The Color of Innocence Essay Example for Free

The Color of Innocence Essay With regards to The Picture of Dorian Gray, one of the most observable and significant themes is that of the shading white and its variations, including, however not restricted to, pale and drowsy. The significance of this shading develops as the novel advances, changing according to Dorians character. While the theme may never truly change in appearance, it prevails with regards to switching meaning totally, implying the extraordinary differentiation in Dorians soul between the start of the novel and the end. In the absolute starting point of the novel, as Basil discusses his first experience with Mr. Dark, he noticed that when their eyes met, I [Basil] felt that I was developing pale (9). The theme comes to mean a kind of tentative straightforwardness; as though Dorians virtue mollifies everything around he comes into contact with. Essentially, Lord Henry utilizes the theme while portraying Dorians youth, marking it as his rose-white childhood (21). Soon after, Dorian is portrayed as having the white virtue of childhood (37). In both of these entries, the theme speaks to its most fundamental implication, that of guiltlessness, especially, the blamelessness of youth. White gives Dorians appearance a feeling of vivacity. Ruler Henry portrays Dorians soul as having gone to this white young lady [Sibyl Vane] and bowed in love before her (57). The theme indicates a young virtue or imperativeness in Sibyl Vanes soul, in all likelihood one that is shared by Dorian Gray. Her guiltlessness before long develops to fuse honest love for Dorian, as subsequent to kissing him, She trembled all finished, and shook like a white narcissus (74). The theme has not turned around its significance now; rather, it joins an ideals like youth and blamelessness, that of adoration. Moreover, as Sibyl Vane performs in front of an audience, Dorian tells how Her hair bunched round her face like dim leaves around a pale rose (74). The composition in Sibyls face recommends an unadulterated wonderful that encapsulates everything attractive to Dorian. He has utilized the theme in portraying Sibyls youth, honesty, energy, and magnificence, all of which appears to reflect Dorians face and soul, as is obvious in Basils depiction of him. The themes significance has arrived at the peak of goodness here, connoting characteristics Oscar Wilde holds in most elevated regard. Be that as it may, it doesn't possess this situation for long, as the following eventsâ begin a broad bastardization of the hues criticalness. As Sibyl Vane proceeds as Juliet before Basil and Lord Henry, The bends of her throat were the bends of a white lilyyet she was inquisitively slow (81). In this presentation Sibyl holds her physical excellence, yet her essentialness has gotten away from her. In a solitary sentence the theme spins to a negative implication, coming to propose an insipid void where there had recently been such intense life. Sibyl, whose obvious flawlessness and ability once encapsulated the theme, has become to Dorian A trashy rate entertainer with a pretty face (85). Her baffling appearing, a conspicuous difference to past exhibitions, prevails in profoundly influencing Dorians meaning of the theme too, as Dorian Gray developed pale as he watched her (81). Afterward, as he cancels his affection for Sibyl, He looked glad, pale, and aloof (83). A word utilized just pages before to depict the excellence of a rose has changed in such extent to be gathered close by such words as glad and detached. The theme used in the representation of Sibyls unhindered fondness is currently used to portray Dorians absence of affection through and through. Profoundly injured by Dorians rant and outcry of only dislike for her, The young lady [Sibyl Vane] developed white, and trembled (85). Though Sibyl had recently taken on such a shading and shivered in the wake of offering her first kiss to Dorian, she does it here because of losing Dorians love. The theme changes from meaning enthusiastic enthusiasm to energetic pity and dread. A shading that gave Sibyl motivation to carry on with her life to the fullest rapidly takes her will and pushes her to end her own life. It is spoken to from a strict perspective too, as Lord Henry portrays the instrument of her demise as having either prussic corrosive or white lead in it (96). Upset by Sibyls inauspicious demise, Dorian dreams, Can they feel, I wonder, those white quiet individuals we call the dead? (96). Rather than depicting enthusiasm, or magnificence, the theme is related with that of a cadaver. Basil alludes to Sibyl Vanes body correspondingly, broadcasting, Why, man, there are detestations coming up for that little white body of hers! (105). Be that as it may, instead of Dorian, Basils utilization of the theme safeguards the immaculateness of Sibyl Vane, perceiving her guiltlessness as an individual. Just Dorians discernments have changed on the importance of the shading; it has become something evil andâ deathly to him, as though the hues significance and essentialness kicked the bucket alongside Sibyl Vane. Master Henry indicates that a drawn out relationship with Sibyl Vane would have been useless, and Dorian concurs, saying, I guessed it would,' as he was strolling here and there the room, and looking horrendously pale (97). As Dorians esteem for human life retreats, and his spirit obscures, one would anticipate that his face should diminish too, as it would have built up the lines and shadows joined by such nature. Be that as it may, this themes meaning, much similar to the pictures appearance, has been compelled to change while Dorian remains the equivalent. Afterward, when Basil demands seeing the appalling representation, Dorian reacts, Basil he stated, looking exceptionally pale, you should not take a gander at it. I dont wish you to' (108). Basil turned pale upon first gathering Dorian, suggesting a modest dread of the young men unadulterated job. Here, when Dorians mystery is compromised, when his detestable soul is at risk for being uncovered and he shows a comparative respons e, it turns out to be evident that whatever dread Basil experienced before is vastly different than the dread Dorian is encountering now. Basil became apprehensive out of veneration, while Dorian became apprehensive out of disgrace. While the theme was already equivalent with virtue, it has embraced a vile, calloused significance with Dorian. Further on, Dorian would put his white hands next to the coarse enlarged hands of the image, and grin. He taunted the deformed body and the bombing appendages (124). In nineteenth century England, white hands were an indication of gentry, and magnificence. Be that as it may, when compared with the dreadful awfulness of the picture and Dorians soul, they appear to be fiendish, and haunting. The theme changes meaning in Dorians eyes, yet in addition in the perusers eyes too. Some time after this, squeezed against the window of the center, similar to a white tissue, he [Dorian Gray] had seen the substance of James Vane watching him (190). Albeit Dorian didn't know about James guarantee to murder him, he comprehends James reason for being there. The theme, completely changed in significance at this point, is an agonizing image of death that Dorian has come to fear. Dorian comes back to the gathering subsequent to seeing James, and As the idea crawled through his cerebrum, he developed pale with fear, and the air appeared to him to have gotten out of nowhere colder (192). Dorians dread of death mirrors James desire for death. The enthusiasm Dorian initially had for what this shading meant hasâ turned into a detestable dread of all it encapsulates. Dorian Grays static appearance can never really stop the change of his general surroundings, or, all the more critically, his spirit. The shading white turns into a theme in the novel that mirrors Dorian Gray; its appearance continues as before, yet as the story advances, it starts to pass on an importance significantly less guiltless than right off the bat. The juxtaposition between the whiteness of virtue at an early stage and the whiteness of death at long last gives the peruser an away from of the advancement of Dorians soul, and in doing as such, it gives a compact comprehension of the plot in general

A Hidden Ocean Might Exist Under Ganymedes Icy Surface

When you think about the Jupiter system, you think of a gas giant planet. It has major storms whirling around in the upper atmosphere. Deep inside, its a tiny rocky world surrounded by layers of liquid metallic hydrogen. It also has strong magnetic and gravitational fields that could be obstacles for any kind human exploration. In other words, an alien place.   Jupiter just doesnt seem like the kind of place that would also have tiny water-rich worlds orbiting around it.   Yet, for at least two decades, astronomers have suspected that the tiny moon Europa had subsurface oceans. They also think that  Ganymede has at least one (or more) oceans as well.  Now, they have strong evidence for a deep saline ocean there. If it turns out to be real, this salty subsurface sea could have more than all the water on Earths surface. Discovering Hidden Oceans How do astronomers know about this ocean? The latest findings were made using the Hubble Space Telescope to study Ganymede. It has an icy crust and a rocky core. What lies between that crust and core have intrigued astronomers for a long time. This is the only moon in the entire solar system that is known to have its own magnetic field. Its also the largest moon in the solar system. Ganymede also has an ionosphere, which is lit up by magnetic storms called aurorae. These are mainly detectable in ultraviolet light.   Because aurorae are controlled by the moons magnetic field (plus the action of Jupiters field), astronomers came up with a way to use the motions of the field to look deep inside Ganymede. (Earth also has aurorae, called informally the northern and southern lights).   Ganymede orbits its parent planet embedded in Jupiters magnetic field. As Jupiters magnetic field changes, the Ganymedean aurora also rock back and forth. By watching the rocking motion of the aurorae, astronomers were able to figure out that theres a large amount of salt water beneath the crust of the moon.The saline-rich water suppresses some of the influence that Jupiters magnetic field has on Ganymede, and that is reflected in the motion of the aurorae.   Based on Hubble data and other observations, scientists estimate the ocean is 60 miles (100 kilometers) deep. Thats about ten times deeper than Earths oceans. It lies under an icy crust thats about 85 miles thick (150 kilometers). Beginning in the 1970s, planetary scientists suspected the moon might have a magnetic field, but they didnt have a good way to confirm its existence. They finally got information about it when the  Galileo spacecraft took brief snapshot measurements of  the magnetic field in 20-minute intervals. Its observations were too  brief to distinctly catch the cyclical rocking of the oceans secondary  magnetic field. The new observations could only be  accomplished with a space telescope high above Earths atmosphere, which  blocks most ultraviolet light. The Hubble  Space Telescope Imaging Spectrograph, which is sensitive to ultraviolet light given off by the auroral activity on Ganymede, studied the aurorae in great detail.    Ganymede was discovered in 1610 by astronomer Galileo Galilei. He spotted it in January of that year, along with three other moons: Io, Europa, and Callisto. Ganymede was first imaged up-close by the Voyager 1 spacecraft in 1979, followed by a visit from Voyager 2 later that year.  Since that time, it has been studied by the Galileo and New Horizons missions, as well as Hubble Space Telescope and many ground-based observatories.The search for water on worlds such as Ganymede is part of a larger exploration of worlds in the solar system that could be hospitable to life.   There are now several worlds, besides Earth, that could (or are confirmed) to have water: Europa, Mars, and Enceladus (orbiting Saturn). In addition, the dwarf planet Ceres is thought to have a subsurface ocean.

Our writers will create an original "Post Merger Performance Of Acquiring Firms From Different Industries Finance Essay" essay for you Create order 1.2 AIMS To analysis the financial statement and Investment ratio of a company or sector during pre and post mergers. (Where they were and where they are). LITERATURE REVIEWS In the last four decades, there were ample number of studies on merger and acquisitions and numerous of theories have been proposed and tested for observed corroboration (Mantravadi, 2008). In an article by Canyon et. al, 2000, merger activity of this form has implications for corporate governance. Although the shareholders may gain from such breach of trust, whereas other stakeholders may suffer and the net consequences are far from clear. While Pillof et.al, 1996, argues, that mergers and acquisition activity results in overall benefits to shareholder when the consolidated post- merger firm is more valuable than the two different entities (pre-merger). Researchers have studied the economic impact of mergers and acquisitions on industry consolidation, returns to shareholders following mergers and acquisitions, and the post-merger performance of companies. Several measures have been suggested for analysing the success of mergers. Such measures have included both short term and l ong-term impacts of merger announcements, effects on shareholder returns of aborted mergers hostile takeover attempts and open offers etc. 3. METHODOLOGY In the effect of merger, this research will calculate a set of financial ratios such as share price difference, price earning, liquidity ratio, debt ratio, market ratios, earning per share, profitability ratios etc, these financial ratios were computed on the basis of pre and post mergers (3 years each). Financial ratios will help the firm to analyse their position. These ratios are also useful to estimate the complete financial position of a firm or an organisation. (Megginson et. al, 2008, p46-51). The post-merger performance will be comparing with the pre-merger performance and tested for significant differences, using paired t test. Further, companies in the sample should not have been engaged in further mergers/acquisitions within four years after the merger under study. A list of companies involved in mergers during 1995-2006 will be compiling from various sources like business magazines, investment web sites, web sites of the BSE and NSE, SEBIs web site (for details of co mpanies making open offers for takeovers), and databases of Capitoline and Prowess. Merger cases where at least two years of data for pre-merger period and at least four years data for post-merger period was not available were removed from the study sample. 4 . METHOD Data Collection and Analysis 4.1 Data collection Data on operating performance ratios for up to three years prior and three years after the acquisition year for each acquiring company in the sample was extracted from Prowess database of CMIE. The sample list of firms was further divided into industry-wise sub-samples (for significant sample sizes). 4.2 Data analysis Pre-merger and post-merger operating performance ratios were estimated and the averages computed for the entire set of sample firms, which have gone through mergers during the period 1995 to 2006. The average ratios for each of the industry sub-samples were also computed. Average pre merger and post merger financial performance ratios were compared to see if there was any statistically significant change in operating performance due to mergers, using paired two sample t-test at confidence level of 0.05. 5. PERSONAL SUITABILITY 5.1 Research background The researcher is graduated from Pune University with commerce as background in 2009 with first class with distinction. During the 3 years of bachelor degree, the researcher undertook various subjects such as accounting, costing, economics, etc. This will help the researcher to write the dissertation on the above topic. 5.2 Present position The researchers currently studying in masters course on management in John Moores University.

Rob Nixon of the New York Times called Naomi Klein’s â€Å"This Changes Everything: Capitalism vs. the Climate† â€Å"a book of such ambition and consequence that it is almost unreviewable.[1]† Naomi Klein researches the impact of Climate change and its relationship with free market capitalism. She discusses capitalism as failed economic system. She goes into great depth on the subject of resource extraction, pollution and the events of surrounding the affected communities in these regions across the world. However, rather than concluding that things are hopeless Naomi Klein argues that: We can build something better and†¦show more content†¦There are people working to make a buck against their own ethical standards and then leaving dirty energy as soon as they can. The openly recognize that the answer to a better life is right under their noses. There are green jobs that could employ the same pool of people same, but not enough political will to support it. Naomi flashes to Hurricane Sandy and talks about the absence of governmental action, she cites the role of government in greece with the economic crisis there and notes how the mining companies have come to prey on that society. Along with what was being promoted as the way out for Greece, the same thing happened in Spain Italy. It is exploitation of resources and sell off whatever you have mentality that gold mining, oil drilling and ultimately in Klein’s opinion; the role of capitalism. She notes that in natural disaster capitalism is predatory and vicious. The agencies that respond to disaster have been gutted due to Reagan-era politics by limiting the role of government in the free market. Unfortunately, this brand of politics purports a â€Å"let’s protect our own† kind of attitude and â€Å"every man for himself.† She talks about the stories that we tell ourselves; the oligarchs are going to save us or the super-hero billionaires will save us with some techno-fix.

Which paragraph was the statement in? A few signs that Elisa is living in a man’s world is the facts that the men were allowed to smoke cigarettes, work outside the home, and engage in business conversations. While the women had to stay home, cook, clean and tend to the children. Elisa attempted to overcome this obstacle and prove to the world she could be as good, if not better than any man. Throughout the story Elisa was only able to prove her strength while behind the fencing of her yard and inside her garden tending to her flowers. You could add more to conclution.

Calculations with Negative Numbers

Calculations with Negative Numbers The introduction of negative numbers can become a very confusing concept for some people. The thought of something less than zero or nothing is hard to see in real terms.  For those that find it hard to understand, lets take a look at this in a manner that may be easier to understand. Consider a question such as -5 ? -12.  What is ?.  The basic math is not hard but for some, the answer would appear to be 7. Others may come up with 17 and sometimes even -17.  All these answers have indications of a slight understanding of the concept, but they are incorrect.   We can look at a few of the practices that are used to help with this concept. The first example comes from the financial view.   Consider This Scenario You have 20 dollars but choose to purchase an item for 30 dollars and agree to hand over your 20 dollars and owe 10 more.  Thus in terms of negative numbers,  your cash flow has gone from 20 to -10.  Thus  20 - 30 -10.  This was displayed on a line, but for financial math, the line was usually a timeline, which added complexity above the nature of negative numbers.   The advent of technology and programming languages has added another way to view this concept that may be helpful for many beginners.  In some languages, the act of modifying a current value by adding 2 to the value is shown as   Step 2.  This works nicely with a number line.  So lets say we are currently sitting at -6.  To step 2, you simply move 2 numbers to the right and arrive at -4.  Just the same a move of Step -4 from -6 would be 4 moves to the left ( signified by the (-) minus sign.One more interesting way to view this concept is to use the idea of incremental movements on the number line.  Using the two terms,  increment- to move to the right and decrement- to move to the left,  one can find the answer to negative number issues.  An example:  the act of adding 5 to any number is the same as increment 5.  So should you start at 13,  increment 5 is the same as moving up 5 units on the timeline to arrive at 18. Starting at 8,  to handle -15,  you w ould decrement 15 or move 15 units to the left and arrive at -7.    Try these ideas in conjunction with a number line and you can get over the less than zero issue, a step in the right direction.

European Union's Policy in Telecommunications Essay

European Union's Policy in Telecommunications - Essay Example Thus the EU telecom market has been undergone some revolutionary process, where new players have come to the market along with offering innovative new services, quality products and low prices. Mobile communications, online services, information through the super highway or the internet have revolutionized the continuous growth and use of telecommunication in almost every sphere of the EU region. Telecommunication companies in EU in particular have introduced not only new but also cheaper combined fixed and mobile service packages with alternative pricing formulas and new ways of paying methods (Noam, 1992). Thus these new developments in the telecommunication policy of EU will be crucial to become a part of the modern Information Society. In fact liberalization of telecommunication is the cornerstone of EU's transition, with lowering the price of communicating, encouraging innovation and investment in new services and networks and contributing to improved competitiveness and increased employment. Thus the Information and Communication Technology (ICT) acquired a significant dimension in the coordination efforts of EU in their both the regional and global operations. ICT i s increasingly becoming the world's most important determinant of integration related issues and actions. For instance EU's significance in the internal and external telecommunication strategy in its global operations can be seen with regard to the level of its applications in coordinating inter-country and intra-country operations. The changing telecommunication environment at overseas and operations has such a big impact on the ICT related decision making process in EU.Thus the transition from monopoly to liberalized telecommunication policy in the competitive world would be a very challengeable to the EU commission. In order to have concrete effects, detailed rules are necessary for the EU and also the application of those rules needs to be careful supervised. So the resources had to be focused on scrutinizing the implementation and practical application of the EU regulatory framework in the Member States. The National Regulatory Authorities (NRAs) for telecoms have been establis hed in member states of EU and range of tasks has set by the EU regulatory framework in order to grant number of telecom services including - to granting new mobile and fixed network licenses; to approving interconnection prices and agreements; policing prices charged to customers for changing operators, and dealing with the allocation of numbers to new market players. Thus the national competition authorities are also occupied with scrutinizing the new telecoms market. In the 1980's telecommunication policy in the EU was characterized by some public monopolies and run with postal services. Thus it has been revolutionized with the privatization and limited competition in some member countries in EU (Damro, 2000). The development of the telecommunication industry has basically been driven by the increasing application of modern information technology in the telecommunica

Follow prompt 3 - Essay Example In the liberation era, there was marked participation of women in the collective labor, contributing to the surplus production that helped the socialist state industrialize. Nonetheless, this period was also characterized by constrained continuation of patriarchal structure that stipulated the type and value of women labor (Hairong 580). At the juncture, women liberation was realized through the participation of women in labor as opposed to the arduous housework they undertook during the earlier days, but gendered division of labor remained intact. Nonetheless, Women’s voices were vociferous in the debates on new modernization policies, as women liberation was related to the defense of the nation (Rofel 43). The women in the later cohort were however more concerned about their personal welfare. Women in the middle cohort are those who matured during the Cultural Revolution era. This group characteristically resisted authority and managerial authority in the industrial workplace. For instance, the cohort resisted younger supervisor Xiao Ma, whereby ignoring her authority was a significant political project (Rofel 222). By refusing the authority of a woman, the cohort essentially expressed its opposition to authoritarianism throughout the society. Workers rights were valued over the labor itself. Middle aged working women defied authority through activism and had extreme attitudes during labor protests. They were opposed to their management’s focus on efficiency by refusing to produce. Their refusal to remain in positions at the shop floor indicates defiance of state power; they exposed the symbolic violence in a natural economic order that is the mainstay of power in the post-socialist modernity (Rofel 19). Therefore, this cohort was against any form of authoritarian ism in factory and in the country in general. There is a similarity in the way the women

Travelodge And Budget Hotels In The Uk Tourism Essay

Travelodge And Budget Hotels In The Uk Tourism Essay Travelodge is the first budget hotel launched in 1985 in UK. It operates 380 hotels with 26,500 room in the UK. Travelodge is planning to grow 1000 more hotels by 2020. It employs above 5500 people and 87% of the booking are made online. The UK hotel market is estimated around 700,000 rooms (source: Melvyn Gold, Qualification of serviced accommodation supply in UK, December 2007) UK hotel market is segmented mainly into four categories, Brander full service which has 14% of the market share, branded budget 12% branded mid market 62% and unbranded independents 62%.the current economic environment has seen increase in drop out of unbranded independents and people prefer to book with branded budget due to network coverage, brand strength strong balance sheet and distribution. Grant Hearn, Travelodge CEO, commented: 2008 was another record year of growth for the Travelodge brand with over 19% revenue growth. Room sold increased by 9 percent to 6 million The growth of Travelodge has been incredible but company faced a few challenges and one of the major challenge company is facing is overbooking. Overbooking is one of the important revenue management tool in hotels operation management to operate effectively and enhance profitability. Revenue Management is seen as an important technique in the hotels operation and therefore to maximize their revenues, hotels are increasingly implementing Revenue Management practices (Hwang and Wen, 2009). As a consequence of implementing such systems, many companies in the service sector such as hotels systematically overbook capacity in order to maximize the revenue at one particular point in time (Wangenheim and Bayà ³n, 2007). If overbooking is not implemented correctly it can result in loss of room revenue, loss of hotel reputation, decreased customer loyalty and decrease hotels profitability. This report discusses the main characteristics of overbooking and its impact on the company in theoretical and practical prospective. Theoretical insights of overbooking One of the central concepts in Revenue Management is overbooking. The practice of overbooking can be defined as confirming more reservations than the hotels available physical capacity to provide the service. (Ivanov, 2006; Ivanov, 2007; Chiang et al 2007; McGill, van Ryzin,1999; Kamath, Bhosale, Manjrekar,2008). Hence, the objective of overbooking is to improve the expected profit and instead of selling each room once, profit can be increased by selling it several times (Birkenheuer, 2009). In fact, overbooking as an integral part of Revenue Management has received significant attention from literature. From a historical perspective, overbooking is present in the studies of Falkson (1969), Simon (1968), Vickrey (1972) and many others. The major objective of these studies was to outline a control practice for cancellations. Nowadays, overbooking has become an emerging matter in industries with perishable products. It yields considerable impacts on companies performance. In terms of the hospitality industry, the profitability of hotels is largely dependent on their utilization of capacity. Conversely, demand for rooms and extensions of stay are very unstable and are hard to predict (van Ryzin, 2005). Hoteliers are challenged by how to determine the occupation of rooms for customers who are financially unequal and meanwhile maintain a stable rate of demand given the hard to predict circumstances (Okumus, 2004). This is all possible utilizing overbooking, which enables proper allocation of resources and optimization of sales. However, maximizing the number of sold rooms per night cannot be easily accomplished. One of the most challenging tasks of the hotel operation management is to deal with the unpredictable nature of the customers, because not all booked reservations will turn into real service consumption (Lai et al, 2005). To this end overbooking may entail a company from the hospitality industry not being able to serve all its customers properly because of lower number of initially expected people that do not appear as agreed. In this respect, overbooking may have both positive and negative impact. On the one hand, it may result in refusal to provide a service, but on the other, it can also take the form of compensation for those bookers, who cannot received the value package they have agreed on and paid for (Kimes and Wagner, 2001). From their practical experience managers know that all not bookings confirmed for a particular date will be really used (Ivanov, 2006). There are several possible scenarios that can cause this. Despite of their reservations, because of different circumstances some guests cancel their stay and terminate their reservations, some does not cancel their booking but fail to show up, or other guests reduce their stay and as a result the room remains unsold and hence capacity not utilize is lost forever (Ivanov, 2006, Talluri et al, 2004; Chiang et al, 2007; Hung, 2004; Bitran; Leon, 1989). Therefore hotels adopt overbooking in order to protect against losses with no-shows and to offset the effect of cancellations and shortened stays (Hwang and Wen, 2009; Kamath et al, 2008; Selmi, 2008; Chiang et al 2007; Hung, 2004; Sulistio, Kim, and Buyya, 2008). Impacts of overbooking on hotels operation management Apart from the opportunity of the hotel to minimize the effect of reservation uncertainties there are possibilities the number of cancellations and no shows to be less then the number of overbookings, then some of the clients will not be accommodated and should be walked to other hotels (Ivanov, 2006). Thus, if a hotel decides to employ overbooking in its operations it should manages carefully not only the opportunity cost of the unsold room but also the overbooking costs for alternative hotel accommodation and transportation that the hotel has to pay in order to compensate a customer in case of overbooking (Ivanov, 2006; Hung, 2004). Besides the evident financial costs occurring in case of walking a guest having already booked, costs the lost hotels goodwill and reputation and the risks of dissatisfaction, loss of trust, loss of future customer loyalty are much more expensive for the hotel (Selmi, 2007). Overbooking policy and control According to Selmi (2007), the risk of customer refusal appears if the overbooking is no realized precisely. In this regard, Kimes (1989) emphasized on the importance of a clearly stated overbooking policy within the hotel operation management. The objective of overbooking policy and control is to find an optimal overbooking level to maximize the expected revenue and to minimize the potential risk of denied service (Chiang et al 2007). Netessine and Shumsky (2002) as cited by Ivanov (2006; 2007) proposed a basic mathematical model for calculating the optimal number of overbookings and according to his findings the optimal overbooking level is inversely related to the amount of cance llation charges applied the closer the cancellation charge to the room rate, the lower the missed benefit from the unoccupied room and the less stimuli to overbook. In case of presence of guaranteed and non-guaranteed bookings, Ivanov (2007) suggests that the optimal number of overbookings has to be set separately for each type. Alternatively, according to Hung (2004) factors that could be considered while setting overbooking limits include: probabilities of cancellation and no-show; room demand distribution over time and conditions of length of stay; stay extension probabilities influenced by the intended length of stay. Moreover Hung (2004) assumes that the proportion of cancellations depends on the customer category, intended length of stay, day of week of first stay over, and time until first stay over. Impact of overbooking on customer behavior According to Talluri et al (2004) overbooking is frequently cited in customer complaints and remains the primary source of dissatisfaction. Moreover, results of an experiment made by Wangenheim and Bayà ³n (2007) confirm that the practice of overbooking is likely to be perceived as unfair by service customers. Wangenheim and Bayà ³n (2007) analyze behavioral consequences of the fairness towards overbooking by proposing and confirming several hypotheses. According to their research the negative consequences of service failure arising from overbooking are stronger for the high status customer than for the low status customers and therefore, hoteliers have to carefully overbook its high-values classes. Additionally, Wangenheim and Bayà ³n (2007) emphasize on the importance that if a hotel ignores the log-run behavior consequences of overbooking, this may lead to negative consequences on its operations. One such negative consequence is proposed to be a customer who faces a denied service due to overbooking and still remains hotels client because of either high fixed switching barriers or current loyalty membership programs. However, in response to the service failure the customer may adjust its investment into the exchange relationship not only by decreasing the number of sales, but also by trying to take advantage of discount offers or purchasing lower level services from the hotel (Wangenheim and Bayà ³n, 2007). On the other hand, Hwang and Wen (2009) analyze the effect of the perceived fairness toward hotels overbooking and compensation practices by examining customers reactions toward hotel overbooking. Some of their most vital findings from this study are that women are more likely than men to feel that overbooking is unfair, customers perceptions to the fairness of overbooking is not affected by other customer variables including length of stay, membership status, payer source, reservation channel, and reservation time; participants perceived fairness toward the hotels overbooking and compensation policies were strongly correlated with positive word-of-mouth publicity. One of the most important results of the research shows that the perceived fairness of the participants toward the hotels compensation policy is related to their loyalty. Therefore, Hwang and Wen (2009) propose that hotels should consider designing compensations that help positively influence customers perceived fairness t oward overbooking and that encourage customers ongoing patronage and loyalty. In a conclusion, issues like determining the optimal number of excess reservations, minimizing compensation cost, and dealing with the negative effects from customers facing a denied service are considered as the most challenging areas of the practice of overbooking and every hotel striving to maximize its profitability should not underestimate them (Sulistio, Kim, and Buyya, 2008). Practical Implications of overbooking As the hospitality industry is evolving, hotel owners and hotel managers are constantly seeking to update their approaches in order to achieve optimal allocation of resources. Novelli, Schmitz and Spencer (2006) have discovered that hoteliers make every effort to employ contemporary technologies in their business. By this implication, hotel managers and owners do not only sustain competitive advantage, but also create new products and services. In view of this, it can be concluded that implementation of new technologies that create new products is a technological innovation (Evangelista, 1999). On the other hand, the implementation of innovative technologies to a service company can have a significant influence in terms of operational efficiency (Freeman and Soete, 1997). Additionally, Porter (1990) supports the latter thesis by highlighting that the performance of a company is highly dependent on new technologies. In view of technological innovations today many hotels recognize the importance of overbooking practice and thus its implementation has become generally accepted step toward hotels successful operations. The practical application of Revenue Management and Overbooking incorporates the following integral elements (Vinod, 2004): Figure 1 Revenue Management application C:UsersamadDesktopCapture.JPG Source: Vinod, B. (2004), Journal of Revenue Pricing Management Market segmentation: Segmenting customers according to their preferences and spending patterns is a must to make sure the most appropriate customers with perfectly fitted attributes are sold the proper rooms that can maximize revenues (Oliveira, 2003). Defining rate classes (inventory pooling): Involves creating groups of the existing rates that close in terms of value (Vinod, 2004). Demand forecasting: demand forecasting is essential to determine room occupancy. In the context of Revenue Management it is important as it can control occupancy using the data of length of stay. This can be achieved by possessing data on rate class demand and duration of stay (Vinod, 2004). Supply forecasting: earlier and late checkouts can also determine room occupancy, which is an element also involved in Revenue Management. Overbooking control: encompasses sales of rooms exceeding the maximum available number of rooms to offset for no shows and cancellations. However, there are some risks associated with overbooking as it may result in grievances from unsatisfied customers who have received an inappropriate room. In such cases hoteliers offer compensations and fringe benefits (Smith, 1982). According to Vinod (1992) Revenue Management can bring 20% of the total revenues. Revenue mix control and exception processing: involves planning important future dates with discretion and matching them with overbooking levels (Vinod, 2004). Performance measurement and management reporting: closely scrutinizing the Revenue Management processes is essential to track down the data quality and future planning basis. However, in order to lead a hotel into a winning direction, overbooking has to be managed and controlled very carefully. Ivanov (2006) defines the management of overbooking as a set of managerial techniques and activities connected with continuous planning, reservation and control and he outlined two main groups of activities that should be performed in the daily hotel operation. The hotel managers should on one hand, to define an optimal number of overbookings for each date and continuously to modify it according to the market changes of the hotel and the specific demand and booking patters and on the other hand, to manage carefully decisions and operational activities related with walking guests with overbookings. In this regard, Ivanov (2006) proposes that factors such as length of stay, rooms rates and client status have to be considered by hotel managers while dealing with walking a guest with confirmed reservation. Additionally, Kimes (1989) analyzes several managerial concerns essential for an effective overbooking practice and states that top management cannot assume that Revenue Management will just happen, it requires careful planning and training. Thus employees have to be i ntensively trained in order to clearly understand the aim and characteristics of overbooking. Moreover, employees who are directly dealing with overbooking decisions have to be periodically trained how to behave in possible customer conflicts and to take their own decisions in an unfamiliar situation (Ivanov, 2006). In order to be minimized the possible customer dissatisfaction in case of overbooking, it is vital for the hotel to establish service recovery programmes with standardized procedures and to make employees to be aware and follow them (Ivanov, 2006) For a profitable applied overbooking in the hospitality industry, hotels must understand not only consumers behavior but also to consider the impact of competition and the currently economic situation that imposes significant supply and demand fluctuations. As hotels compete with each other in order to attract more customers, Revenue Management decisions of one hotel inevitably influence the demand for other hotels in the same region or area. However, recent trends propose that hotels should collaborate with is competitors that result in increased number of formed alliances with each other to maximize their revenue (Chiang et al, 2007) Revenue Managements challenges in the hospitality industry As explained before, Revenue Management finds application to two significant industries: hospitality and airline. The first one, however, is much more complex in terms of industry saturation and rooms management. This creates hurdles for the optimal operation of Revenue Management techniques. I n the hotel industry Revenue Management can be applied either locally or via centralized system. The second one involves gathering data and taking decisions from a focal site for other properties. In practice only a limited number of hotels and hotel chains are able to manage centralized data processing and therefore the majority of players on the hospitality industry opt for property based Revenue Management. Recommendations for future research Despite of the acknowledged importance of overbooking as one the most effective successful Revenue Management techniques used in hotel operation and widely discussed topic in research literature, there are no current studies discussing the overbooking management of Bulgarian hotels and its impact on their operation. Therefore, future research may focus on the possible application of Revenue Management techniques to the Bulgarian hospitality industry. Future studies may also focus on the demand side of Bulgarian tourism as the country has witnessed fluctuating visitor rates during the past two decades despite the growing profits generated by the particular industry. Conclusions In order to survive in the furious competition and to generate more revenue while using the same amount of recourses it is necessary and critical to the hotels operation management to use effectively its reservation inventory and to increase its occupancy rate (Hung, 2004). Revenue Management techniques and the models of overbooking if applied appropriately would maximize the revenues of hotels (Kamath et al, 2008). However, the possibilities of customer dissatisfaction, and risk of loss of reputation because of denied service, force many hotels to avoid the practice of overbooking. Therefore, before hotel managers to deicide whether or not to implement overbooking they should first consider what Birkenheuer (2009) explained the best estimation of risk and opportunity will provide the best profit. In this study we have outlined the dynamic nature of service industries and have demonstrated the importance of Revenue Management and most notably one of its most significant aspects ove rbooking. We have narrowed the scope of this research down to the hospitality industry and have found major differences in the demand patterns towards such companies in the former industry. Some customers prefer flexible cancellation terms, while others are not much attentive to that. Hoteliers offer differential pricing to their own advantage to hedge against fluctuating demand. We have also found that substitution is one of the most effective method of managing overbooking practices, but yet a cost/benefit analysis must be performed in order to track down the real consequences. Essentially, within the current dynamic decision making situation in the hospitality industry, overbooking levels have been found to have significant revenue maximizing properties. In view of this, through this study we have discovered some of the chief management objectives that could be achieved through overbooking in the framework of Revenue Management: profit maximization; capacity allocation; maximizat ion of average revenue per customer; maximization of net present value; and minimization of customer grievances. Finally, as hospitality industry on a global scale is a mass volume-driven business, overbooking has become an emerging topic as vacant rooms do not bring any profits. However, perhaps even more significant remains the problem how to manage customer disappointment, in cases they cannot be relocated to similar hotels as a result of overbooking.

Shakespeare’s Richard II Essay: Search for Identity in Richard II

Search for Identity in Richard II Â   Shakespeare's Richard II tells the story of Richard's fall from power. Being dethroned by Bolingbroke forces Richard to confront the limitations and nature of his power as king. As audience members, we follow Richard on his journey of self-discovery, which enlightens him even as his life is shattered by Bolingbroke's revolt. Paradoxically, it is in utter defeat that Richard comes closest to understanding what it is to be human. Unfortunately he is unable to accept life as an ordinary subject after having tasted what it means to rule. For God's sake, let us sit upon the ground, And tell sad stories of the death of kings- How some have been deposed, some slain in war, Some haunted by the ghosts they have deposed, Some poisoned by their wives, some sleeping killed, All murdered. For within the hollow crown That rounds the mortal temples of a king Keeps Death his court; and there the antic sits, Scoffing his state and grinning at his pomp, Allowing him a little breath, a little scene, To monarchize, be feared, and kill with looks, Infusing him with self and vain conceit, As if this flesh which walls about our life Were brass impregnable; and humored thus, Comes at the last, and with a little pin Bores through his castle wall; and farewell, king. Cover your heads, and mock not flesh and blood With solemn reverence. Through away respect, Tradition, form, and ceremonious duty, For you have but mistook me all this while. I live with bread, like you; feel want, Taste grief, need friends. Subjected thus, How can you say to me I am a king? (III.ii. 151-1173) Â   The above speech expresses nicely Rich... ...n is, With nothing shall be pleased till he be eased With being nothing. (V.v.38-41) Richard can never bring himself to be "eased" with being ordinary, with being what he sees as "nothing" and so he can never live as a subject instead of a ruler. It is perhaps significant that when he dies he seeks to return to the only identity he really knew, that of a ruler, and warns that "Exeter, thy fierce hand / Hath with the King's blood stained the King's own land" (V.v. 109-10). He has accepted intellectually the transient nature of kings' power and understands he can no longer possess even that, yet in death he reaches for the only identity he ever really held, that of absolute monarch.

K-19 Disaster

Leadership is the process in which an individual influences the group of individuals to attain a common goal. Good leadership ensures that the goal is attained by mutual cooperation and cohesive behavior. An effective leader infuses a sense of positivist and efficiently directs others to reach the specified goal.The captain in the movie placed too much emphasis on power. A captain who attempts to control circumstances with power most often becomes authoritarian in his expression which can lead to dissent among subordinates. On the other hand, a captain who communicates effectively and collaborates with all team members is often respected and becomes more successful. In K- 10, the co-captain was an antithesis to the actual captain. The stark contrast between the two men's leadership styles conveyed a message about the relative effectiveness of each one.The crew embers were more loyal to the co-captain because he worked as a team to reach a goal Instead of ordering his subordinates ar ound. When disaster struck the crew was more apt to follow orders from the authority figure who worked with them as a team because they trusted him to care for their well-being. The only way to efficiently govern a large number of people is to instill a sense of trust. Those who abuse their power will not be trusted and thus will not become effective leaders. During war time people tend to experience and strong sense of nationalism.A citizen of Russia n the movie would feel patriotism for his own country starting at a very early age. It's a socio-cultural phenomenon that has been examined for ages. Many social psychologists believe that the patriotism is derived from the innate human desire to belong. Therefore, when Russian begins to experience military tensions during the onset of WWW, many citizens felt the need to defend and protect not only the country's honor, but their own as well. This explains why it was so hard for the captain to abandon the mission that his government had assigned him to.He felt that it was only right to risk his life defending his country and his own reputation, When technology advances rapidly, there is often a discrepancy between the capabilities of technology and the capabilities of the people in charge of said technology. Examples of such discrepancies can be found throughout all time periods. During the industrial revolution, for example, the technology allowed for mass production of goods, but the society of the time did not have regulations in place to successfully prepare workers for the hazardous conditions. As a result many lives were tragically lost.During WWW, Germany was beginning to use planes In the war. However, the first airplane had been flown Just over a decade earlier and the technology was still in its Infancy. Consequently, the average life span of a fighter pilot In WWW was only two weeks. When watching K-19 it is quite easy to understand why such a disaster could occur. The government at the time was despera te to have the cutting-edge technology, but did not have time to properly train those who would be working with the equipment. In today's society our technology Is once again advancing at a 1 OFF startling rate.As social medial becomes more prominent, minors are more expos to the adult world and the dangers that accompany it. We must be careful, as a society, to guard against technology being controlled by those who don't know how to properly utilize it. The movie was a powerful, reality based drama that causes viewers to consider the effects of nuclear power and the dangers of radiation. However, it also has underlying tones that speak to the very nature of humans. Leadership skills, nationalism, and technological innovation continue to be pressing issues in society throughout the ages.

INTRODUCTION Injuries to the distal tibiofibular syndesmosis are complex and remained controversial with regard to diagnosis and management. Don’t waste time! Our writers will create an original "Treatment of ankle syndesmosis injuries" essay for you Create order In United Kingdom, ankle fractures are the most common fracture among patients aged between 20 and 65 with the annual incidence reported as 90,000 (1). Twenty percent20% of ankle fractures requireing internal fixation (2), and or 10% of all ankle fractures are associated with syndesmosis disruption (3). Syndesmotic injuries have also been reported in the absence of fracture and sometime called as high ankle sprainwith incidence reported somewhere between 1% and 11% of all ankle fractures or 0.5% of all ankle sprains (4-6). Despite the considerable tremendous amount of work load these injuries provide for orthopaedic surgeons, there is no consensus regarding the optimal treatment of these injuries, resulting and sometime results in under or over treatment of syndesmotic injuries, especially those without fibular fracture. It is therefore important to understand the anatomy, biomechanics and the mechanism of injuries involving the tibiofibular syndesmosis. 1.1. Anatomy The inferior tibiofibular joint is a syndesmotic joint formed by two bones and four ligaments. The distal tibia and fibula form the osseous part of the syndesmosis held together by four ligaments providing stability that is integral for proper functioning of the ankle joint (6-8). These ligaments include the anterior inferior tibiofibular ligament (AITFL), the posterior inferior tibiofibular ligament (PITFL), the transverse tibiofibular ligament and the interosseous ligament. At the apex of syndesmosis, the interosseous border of tibia bifurcates caudally into an anterior and posterior margin. The anterior margin ends in the antero-lateral aspect of the tibial plafond called the anterior tubercle (Chaputs tubercle). The posterior margin ends in the posterolateral aspect of the tibial plafond called the posterior tubercle. The anterior and posterior margins of the distal tibia enclose a concave triangular notch called insisura fibularis, with its apex 6-8 cm above the level of the talocrural joint (9-11). The anterior tubercle is more prominent than the posterior tubercle and protrudes further laterally and overlaps the medial two thirds of the fibula (9-11). The fibular part of the syndesmosis is convex and matches with its tibial counterpart. The crista interossea fibularis, i.e. the ridge on the medial aspect of the fibula, also bifurcates into an anterior and posterior margin and forms a convex triangle that is located above the articular facet on the lateral malleolus. The base of the fibular triangle is formed by the anterior tubercle (Wagstaffe-Le Fort tubercle) and the, almost negligible, posterior tubercle (9). Shape of insisura fibularis varies among individual. Elgafy et al (12) described two main morphological patterns in their study of 100 normal ankle syndesmoses. In 67% the insisura was deep, giving the syndesmosis a crescent shape while in 33% it was shallow, giving the syndesmosis a rectangular shape (12). The anterior inferior tibiofibular ligament AITFL runs obliquely from anterior tubercle of distal tibia to anterior tubercle of fibula [Fig. 1.1]. AITFL consists of multifascicular bundle of fibers that run obliquely downwards and laterally and prevents excessive fibular movement and external talar rotation (13). The AITFL is the first ligament to fail in external rotation injuries (9). Posterior inferior tibiofibular ligament PITFL is a strong ligament. It originates from posterior tubercle of distal tibia and runs obliquely downwards and laterally to the posterior lateral malleolus (14) [Fig. 1.2]. PITFL works along with AITFL to hold the fibula tight in insisura fibularis of the tibia. The lower part of the PITFL runs more horizontally and is considered as a separate anatomical entity called transverse ligament. The transverse ligament is a thick, strong structure with twisting fibers. It passes from the posterior tibial margin to the posterior margin of malleolar fossa of distal fibula. The location of the transverse ligament below the posterior tibial margin creates a posterior labrum, which deepens the articular surface of the distal tibia and helps to prevent posterior talar translation [Fig. 1.2]. The interosseous tibiofibular ligament is a thickening of lower most part of interosseous membrane and consists of numerous short, strong, fibrous bands which pass between the contiguous rough triangular surfaces of the distal tibia and fibula and form the strongest connection between these bones, providing stability to talocrural joint during loading. The ligament is thought to act like a spring, allowing for slight separation between the medial and lateral malleolus during dorsiflexion at the ankle joint and thus for some wedging of the talus in the mortise (9). Ogilvie-Harris et al (15) studied the relative importance of each of the ligaments in the distal tibiofibular syndesmosis using 8 fresh-frozen cadaver specimens to evaluate the percentage of contribution of each ligament during 2 mm of lateral fibular displacement. The anterior inferior tibiofibular ligament provided 35%; the transverse ligament, 33%; the interosseous ligament, 22%; and the posterior inferior ligament, 9%. Thus, more than 90% of total resistance to lateral fibular displacement is provided by 3 major ligaments. Injury to one or more of them result in weakening, abnormal joint motion, and instability. 1.2. Biomechanics The primary movements at the ankle joint include dorsiflexion and planterflexion. The normal ankle allows approximately 15o to 20o of active dorsiflexion which may be increased to 40o passively and between 45o to 55o of plantar flexion (16). The superior surface of the talus is wedge shaped and wider anteriorly than posteriorly with an average difference of 4.2 mm (17). During dorsiflexion, the wider anterior portion of the talus wedges between the medial and lateral malleoli, and much of the mortise becomes occupied (6). Up to 6o of talar external rotation occurs during ankle dorsiflexion and the talusit rotates internally and supinates slightly during plantar flexion, as a result of its conical and wedged shape (17-19). During normal ankle motion, some movement occurs normally at the distal tibiofibular syndesmosis. Although ankle syndesmosis is a tightly held fibrous joint it allows 1 to 2 mm of widening at the mortise as the foot is moved from full plantar flexion to full dorsifl exion. This widening of mortise occurs partly as a result of 3o to 5o of fibular rotation along its vertical axis during plantar flexion and dorsiflexion (6, 18, 20). When fixing ankle fractures, it is vital necessary to restore normal anatomic relations of distal tibiofibular syndesmosis, as slight discrepancy can lead to significant change in biomechanics and sub optimal long term results. Ramsey and Hamilton (21) demonstrated that as little as 1 mm of lateral shift of the talus in the ankle mortise resulted in a 40% loss of tibiotalar contact surface area and increase in contact stresses. Similar findings were also confirmed by another recent study by Lloyd et al (22) in 2006. Taser et al (23) showed using three-dimensional computed tomographic (CT) reconstructions that a 1 mm separation of the syndesmosis can lead to a 43% increase in joint space volume. 1.3. Mechanism of Injury The 3 proposed mechanisms of ankle syndesmotic injury include external rotation of the foot, eversion of the talus and hyper dorsiflexion (6, 24). External rotation injuries result in widening of the mortise as the talus is forcefully driven into external rotation within the mortise. Forceful eversion of the talus also results in widening of the mortise. These mechanisms are most common in sports like football and skiing. Hyperdorsiflexion injuries are seen in jumping sports and also result in widening of mortise when wider anterior part of the talus dome is forcefully driven into the joint space. In all cases, the fibula is pushed laterally and if the forces are strong enough, leads to diastasis of ankle syndesmosis (24-30). Lauge-Hansen (31) classified the ankle fractures according to the mechanism of injuries. This classification system was based on cadaveric study and takes into account the position of foot at the time of injury and the deforming force. According to this syndesmotic disruption most commonly occurs in Pronation-External Rotation (PER) injuries. Depending on the severity of the force applied, this abnormal movement will result in rupture the deltoid ligament or fracture the medial malleolus in its first stage, with subsequent injury to the syndesmotic ligaments and the interosseous membrane, and finally a spiral fracture of the fibula above the level of syndesmosis (31, 32). Most of the complete syndesmotic disruptions are associated with Weber C fracture with smaller proportion having Weber B fracture with widening of the mortise and, occasionally, a Maissonneuve fracture (33). Syndesmotic diastesis rarely occurs in isolation without bone injury and poses a diagnostic challenge. These injuries are sometime referred as high syndesmotic sprain (4, 27, 34). 1.4. Diagnosis Diagnosis of syndesmotic injury can sometime be challenging and depends on high index of suspicion, taking into consideration, the mechanism of injury and the clinical findings and confirming with radiological assessment or examination under anaesthesia. Several clinical tests have been described in literature but lack high predictive value in acute cases as it might be difficult to perform these tests because of excessive pain in acute situations. Some examples of these tests include Squeeze test (34), Point test (35), External rotation test (32, 35) and Fibular translation test (32, 36). Radiographs are important in diagnosis of tibiofibular syndesmotic diastasis. Three radiographic parameters have been described based on anterior-posterior and mortise views but controversy exist among researchers with regard to the optimal parameter for accurate diagnosis. The tibiofibular clear space is defined as the distance between the lateral border of the posterior tubercle and the medial border of the fibula. The tibiofibular overlap is the distance between the medial border of the fibula and the lateral border of the anterior distal tibial tubercle and the medial clear space is the distance between the articular surface of medial malleolus and the adjacent surface of talus (32, 37). Harper et al (38) radiographically evaluated normal tibiofibular relationship in 12 cadaver lower limbs and based on a 95% confidence interval, demonstrated following criteria as consistent with a normal tibiofibular relationship: (1) a tibiofibular clear space on the anterior-posterior and morti se views of less than approximately 6 mm; (2) tibiofibular overlap on the anterior-posterior view of greater than approximately 6 mm or 42% of fibular width; (3) tibiofibular overlap on the mortise view of greater than approximately 1 mm. The study concluded that the width of the tibiofibular clear space on both anterior-posterior and mortise views appeared to be the most reliable parameter for detecting early syndesmotic widening and medial clear space greater than a superior clear space is indicative of deltoid ligament injury (38). The accuracy of these measurements has been questioned in several studies. Beumer et al (39) demonstrated that these measurements are greatly influenced by the positioning of ankle while taking radiographs. Similar findings were confirmed by Nelson et al (40) and Pneumaticos et al (41) except that the later study reported that the tibiofibular clear space did not change significantly by rotation of ankle (41). CT and MRI scanning are more sensitive tha n radiography for detecting minor degrees of syndesmotic injury and provide an important diagnostic tool in suspicious cases (7, 42). 1.5. Treatment of Syndesmosis diastasis and review of literature Injuries to distal tibio-fibular syndesmosis are complex and require accurate reduction and fixation for optimal outcome (43, 44) but the choice of fixation still remained controversial. Kenneth et al (45) studied the effect of syndesmotic stabilization on the outcome of ankle fractures in 347 patients at a minimum follow up of 1 year and concluded that patients requiring syndesmotic stabilization in addition to the malleolar fixation had poorer outcome as compared to patients requiring only malleolar fixation. Although, the use of metal screw has been the most popular means of stabilizing the syndesmosis (32), controversy exists with regard to the size and number of screw, number of cortices engaged, level of screw placement above the tibial plafond, need for routine removal and the timing of the screw removal (46-48). Beumer et al (49) in their cadaveric study, reported no difference in fixation of the syndesmosis when stainless steel screws were compared to titanium screws through three or four cortices. Hoiness et al (46) conducted a randomised prospective trial comparing single 4.5 mm quadricortical screw with two 3.5mm tricortical screws for ankle syndesmosis injuries in 64 patients. The study showed improvement in early function in the tricortical group, but after one year there was no significant difference between the groups in their functional score, pain or dorsiflexion (46). Further report on the same study group with 8.4 years average follow up did not show any significant diff erence in clinical outcome (50). Moore et al (51) also reported similar functional outcome with either three or four cortical fixation using 3.5 mm screws with slightly higher trend toward loss of reduction in tricortical group. Although there is no clinical consensus regarding number and size of the screws, biomechanical studies have shown that two screws are mechanically superior to single screw (52). There is no significant difference between 3.5 mm and 4.5 mm syndesmosis screw when used as tricortical screw (48) but when used as quadricortical screw 4.5 mm screw showed higher resistance to shear stress than 3.5 mm screw (53). Routine removal of syndesmosis screw is another controversial issue. Some authors advocate routine removal before starting full weight bearing as screw provides rigid fixation of syndesmosis where micromotion occurs normally and can therefore lead to screw loosening or fatigue failure (54-57). Miller et al (58) demonstrated improved clinical outcomes follow ing syndesmosis screw removal in a series of 25 patients. Manjoo et al (59) retrospectively reviewed 106 patients treated with syndesmosis screw. Seventy-six returned for follow up. The study concluded that intact screw was associated with a worse functional outcome as compared with loose, broken or removed screws. However there were no differences in functional outcomes comparing lose or broken screws with removed screws (59). Both these studies had inherent limitations including of retrospective studies study design and lack of a the control group. Malreduction of tibiofibular syndesmosis has been reported as a significant problem with screw fixation and is an independent predictor of functional outcome (44). Gardner et al (60) reported 52% of malreduction of syndesmosis in weber C fractures treated with screw fixation. Bioabsorbable screws haves also been used as an alternative to metal screws to avoid hardware related complications and haves demonstrated equal effectiveness in fixation of diastesis (61-63). However, these implants did not gain popularity because of concerns including osteolysis, foreign-body reaction, late inflammatory reaction and osteoarthritis due to polymer debris entering the joint (64-67). The Arthrex Tightrope is a relatively new surgical implant based on the suture endobutton design. It is a low profile system comprised of a No. 5 FiberWire ® loop which, tensioned and secured between metallic buttons placed against the outer cortices of the tibia and fibula, provides physiologic stabilization of the ankle mortise and obviates the need for a second procedure for removal, therefore late diastasis is unlikely (68). Biomechanical testing and clinical trials have shown equivalent strength and improved patient outcome with the tightrope technique (69, 70). In 2005 Thornes et al (71) performed a clinical and radiological comparison of 16 patients treated with suture-button techniques with similarand a similar cohort of patients treated with syndesmosis screw fixation. Patients in suture button group demonstrated significantly better American Orthopaedic Foot and Ankle Society (AOFAS) score and returned to work earlier than screw group. As with any novel technique, th e follow-up reported in the literature is short and the number of cases are limited [Table 1]. The largest case series so far, has reported the outcome in 25 cases patients (72, 73). Although initial series did not report any complications, some cases of implant removal have been reported in more recent literature because of soft tissue irritation. In a series of 16 patients, two tightropes were removed, one due to infection, and the other due to soft-tissue irritation (74). Willmott et al (75) reported 2 cases of tightrope removal because of soft tissue inflammation, out of 6 patients treated with ankle tightrope (33%). One of them was removed because of inflammation over medial button. Coetzee et al (76) in their results of a prospective randomized clinical trial also reported removal of one tightrope because of infection, out of 12 cases. In a most recent series of 24 cases DeGroot et al (77) reported removal of hardware in 6 patients due to soft tissue complication. They also re ported subsidence of endo-button due to osteolysis in adjacent bone in 4 cases but did not have any effect on clinical outcome as it was a late occurrence. There were also 3 cases of heterotopic bone formation in this series. Table 1 : Studies reporting o n clinical outcomes and complications of Tightrope fixation .

Despite satisfactory short term clinical outcomes, few complications have also been reported related to soft tissue irritation and also there is a concern that tightrope might be inferior to screw in maintaining the syndesmosis. So far, the literature is limited with regard to tightrope fixation and the issue of malreduction has not been properly investigated. Radiological measurements in most of the studies are performed on radiographs. It has been previously noted that radiographic measurements are influenced by the rotation of ankle and therefore not accurate. Thornes et al performed axial CT scan on 11 of 16 patients treated with tightrope at 3 months and did not find any malreduction (71). CT scans were performed only after 3 month of surgery and none of the patient in control group had a CT scan and therefore undermines the significance of this part of their study. Significant malreduction of tibiofibular syndesmosis has been reported in literature for patients treated with sy ndesmosis screw (50, 60). As malreduction of syndesmosis is the most important independent predictor of long term functional outcome we aim to fill the gap in literature regarding tightropes ability to maintain syndesmosis integrity in longer term.

PATIENTS AND METHODS We conducted a cohort study to assess the radiological and clinical outcomes of patients after treatment of ankle injuries involving distal tibiofibular syndesmosis. Two different methods of syndesmosis fixation were compared (standard transosseous syndesmosis screw fixation and a relatively new, Tightrope fixation technique) for the accuracy and maintenance of syndesmosis reduction and its correlation with the functional outcome scores after at least 18 months following the index procedure. The accuracy of syndesmosis reduction was measured primarily on axial Computed Tomographic (CT) scans and anterio-posterior (AP) radiographs of ankles using uninjured contralateral ankle as a control. The study was conducted in department of Trauma and Orthopaedics and the department of Radiology in Our Lady of Lourdes Hospital, Drogheda, Republic of Ireland after approval by the Institutional Review Board (appendix i). The patients were recruited using trauma theatre database. The data regarding all patients treated for ankle injuries was reviewed. The inclusion criteria were as follows: adults ( 18 years) with acute ankle syndesmosis injury willing to give informed consent to participate in the study , fixation of the injuryed over a 2 years period from July 2007 to June 2009 provided they did not fit into the exclusion criteria. The exclusion criteria set out for this study included: P patients with open fracture, I i ndividuals with diabet es ic or neuropathic arthropathy, M multi trauma patients and P patients who had a previous injury or surgery on the contra-lateral ankle as those could not be used as a control. Pregnancy was included in exclusion criteria B because of radiation exposure in this study. pregnancy was also mentioned as exclusion criteria. i I ndividuals unwilling to consent to the study Patients were treated by six Orthopaedic consultants in a single trauma unit using two different techniques for syndesmosis fixation including traditional screw and tightrope fixation technique. Three consultants used screw fixation while the other three consultants used tightrope technique for all of their patients requiring syndesmosis fixation irrespective of age, sex and the type of associated fractures. The diagnosis of tibiofibular diastasis was based on careful clinical examination, consideration of the fracture pattern and radiographic parameters including widening of medial clear space (MCS), increased tibiofibular clear space (TFCS) and reduced tibio-fibular overlap (TFOL) preoperatively; and intraoperative confirmation under fluoroscopy using external rotation stress test and hook test in which fibula was pulled laterally after fixation of fracture using a bone hook and widening of syndesmosis was observed using image intensifier. Concomitant fractures of fibula and medial malleolus were fixed according to standard AO principles. Ankle syndesmoses were stabilized with either Transosseous Screw or Tightrope depending on the consultants preference. All patients were immobilized in below knee plaster back slab for two weeks followed by non-weight bearing cast for another four weeks. Casts were removed in after six weeks time and patients were referred for physiotherapy and allowed full-weight bearing as tolerated. Patients were followed up in clinic at 2 weeks, 6 weeks and then after 3 months. Patients were finally reviewed in January 2011 for the collection of study data. Patients who consented for the research participationto this study underwent a clinical examination by an independent clinician who was blinded for the type of syndesmosis fixation. Two functional scoring systems were used to assess clinical outcome, including a clinician reported American Orthopaedic Foot and Ankle Society (AOFAS) scoring system (78) and a patient reported Foot and A nkle Disability Index (FADI) score (79). Radiographic assessment included anterior-posterior radiograph of both the ankles together and an axial CT scan of both the ankles together at 1 cm above the tibial plafond. All the CT scans were performed by single, senior CT Radiographer using same specifications.   All patients were scanned supine in the axial plane with no gantry tilt.   Survey CT scan image was obtained first instead of scanning the whole ankle, to reduce the radiation dose. The area of ankle syndesmosis was scanned using single slice CT scan. The thickness of the CT slice was 3.8 mm and was centred at 12 mm from the tibial plafond as measured on the survey scan image. This sSingle slice scan provided two axial images, one at approximately 1 cm from the tibial plafond and other at 1.4 cm approx [Fig. 2.1]. This technique was adopted in order to reduce the radiation exposure to the patient without compromising the quality of the scans and the axial images th us obtained correspond to the same level as used for the measurements on radiographs i.e. 1 cm above tibial plafond. 2.1. Outcome Variables The accuracy of syndesmosis reduction on axial CT scan was considered as primary outcome variable to compare the two different treatment options. The criterion for malreduction of syndesmosis was set at 2 mm of difference in the width of syndesmosis as compared with the normal contralateral ankle when measured on the axial CT scan. The width of posterior part of syndesmosis joint space was measured for the purpose of this comparison as this measurement correspond to the tibiofibular clear space on AP radiographs. The criterion was set at 2 mm in accordance with previous literature (60) and the assumption that this difference will result in sufficient level of joint incongruity which may lead to increased contact pressures in ankle joint and the risk of early degenerative changes (21, 22). Elgafy et al (12) reported that the average width of syndesmosis posteriorly is 4 mm with standard deviation of 1.19 mm. As this area corresponds to the tibiofibular clear space on AP radiographs a nd 6 mm of tibiofibular clear space is considered abnormal, the criterion of 2 mm would be justified.   Syndesmosis integrity was also assessed on AP radiographs of ankle, using parameters including tibiofibular clear space (TFCS 6 mm), tibiofibular overlap (TFOL 6 mm) and medial clear space (MCS 5 mm). Clinical outcomes were assessed using two functional scores, time to full weight bearing and rate of complications. Functional scoring systems include American Orthopaedics Foot and Ankle Society (AOFAS) score (appendix ii) which has been widely used in previous ankle studies. It is a clinician reported scoring system which looks at the pain, functional status, alignment and range of motion of foot and ankle. Foot and Ankle Disability Index (FADI) score (appendix iii) is a patient reported functional scoring system and looks at pain and various functional activities. Both the scores range from 0 to 100 with higher scores indicating better function. In the statistical analysis, factors considered potential confounders were patients age and the durationtime since surgery. These confounders were adjusted using regression analyses. 2.2. Data Collection and Measurements Demographic data of the patients and the data regarding the mechanism of injury, type of fractures and the type of fixation were extracted from patients clinical notes. Radiographic parameters of syndesmosis integrity were measured on preoperative and the latest AP ankle radiographs 1 cm proximal to the tibial plafond. The tibiofibular clear space is defined as the distance between the lateral border of the posterior tibial tubercle and the medial border of the fibula. The tibiofibular overlap is the distance between the medial border of the fibula and the lateral border of the anterior distal tibial tubercle and the medial clear space is the distance between the articular surface of medial malleolus and the adjacent surface of talus (32, 37). The width of syndesmosis was measured on axial CT scan for both operated and normal ankles simultaneously. Measurements were performed on axial scan 1 cm proximal to the tibial plafond as described earlier to provide measurements that are comparable to those obtained on standard radiographs. The distal fibula shows considerable variation with regard to the prominence of the borders. Four borders of fibula have been mentioned in anatomy textbooks including anterior, posterior, medial and interosseous border [Fig 2.2]. As the cross-sectional anatomy of distal tibia is more constant than fibula we used anterior and posterior tibial tubercle as our reference points for the measurements of anterior and posterior syndesmosis width. Although anterior width of syndesmosis was not used for comparison of malreduction, it was measured to evaluate normal anatomic variations in uninjured ankle syndesmosis. Two measurements were performed. Anterior width was measured from anterior tibial tubercle to the nearest point on the fibula. Similarly, the posterior width was measured from posterior tibial tubercle to the nearest point on the medial boarder of fibula [Fig. 2.3]. Measurements were performed by an independent musculoskeletal rRadiologist on using digital software on CT work station. CT measurements were performed twice at an interval of 2 weeks without the knowledge of previous readings, to assess the intra-observer agreement. Clinical assessment was performed by an independent clinician who was blinded for the type of syndesmosis fixation. AOFAS and FADI scores were completed at this review. As this was a non-randomised study there were possibilities of bias and every effort was made to reduce the bias. All consecutive patients who fulfilled the eligibility criteria were invited for participation in the study to reduce the selection bias. It was confirmed retrospectively that different methods of syndesmosis fixation were assigned to patients only on the basis of surgeons preferred choice, irrespective of age, sex or type of associated fracture. This means thatIn essence, patients admitted on certain days of the week were fixed with syndesmosis screw and patients attending on the remaining days were treated with tTightrope fixation technique. Measurements on the CT scan and radiographs were performed by an independent radiologist. As blinding was not possible, measurements were performed twice at an interval of 2 weeks to assess intra-observer reliability of measurements. Finally, the clinical assessment was performed by an independent clinician not directly involved in the study and was blinded to the type of fixation. This was important to reduce assessors or interviewers bias. 2.3. Sample Size Sample size was calculated on stata 11.1 for comparison of two means, using measurements of normal syndesmosis on CT scan as reported by Elgafy et al (12) . Using mean of 4 mm and standard deviation of 1.19 and considering 2mm as clinically significant difference gives minimum of 10 cases in each group for 90% power. Although 2 mm difference is used for detection of malreduction in individual patient, there might not be a mean difference of 2 mm. Therefore we calculated the sample size for one standard deviation difference from the normal mean value which requires 22 cases in each group. A sample size calculation was performed based on the primary outcome measure i.e. measurements of normal syndesmosis on CT scan as reported by Elgafy et al (12) Elgafy et al . The formula used to determine the number of participants required in the study involved the prediction of the standard deviation ( à Ã†â€™ ) for normal CT measurements and an anticipated significant clinical change or deviation from normal CT measurements of the ankle (Ά) [Fig. 2.4] . The value for the à Ã†â€™ was obtained from the paper by Elgafy et al (12) Elgafy et al . Although 2 mm difference is widely used for detection of malreduction in individual patient s , the difference is often not 2 mm in individuals presenting with problems. Therefore we considered 1 millimetre as a clinically significant difference (Ά) so that the final power of the study is not undermined . The value of the constant K, 7.8, was dictated by the significance level chosen for the study, in this case a two- sided significance level of 5% with an 80% chance of detecting a treatment effe ct. Based on a two group comparison, power calculations indicated that a minimum of 46 participants were required to detect a change of 1mm on the CT measurements at a two-sided significance level of 5% and a power of 80%, assuming a à Ã†â€™ of 1.19 points. This analysis was confirmed using Stata 11.1  ® statistical software. Number of participants required in each of the comparison groups must be greater than the value calculated using the following formula 2 (Constant K) ( à Ã†â€™ of the normal CT measurements) 2 (What is considered to be a clinically significant change in CT measures) 2 2 (7.8 for two sided test with significance level of 0.05) (1.19) 2 (1) 2 2 (7.8) (1.42) 1 23 participants per group Therefore in order to detect a clinically significant change of 1 mm deviation on the CT measurement, a minimum of 46 participants were required in total 2.4. Statistical Analysis Statistical analysis was performed on Stata 11.1 ®. Demographics were compared for the two groups using mean values and proportions. Mean, standard deviation, ranges and confidence interval (CI) were calculated for the continuous variables including age, follow-up, time to full weight bearing, radiographic and CT parameters and functional outcome scores. Mean values were calculated for the radiographic and CT parameters for both operated and normal ankle in two groups separately and compared using t-test within each group for measurement of statistical significance. Difference in the width of syndesmosis between normal and operated side were calculated and compared using unpaired t-test with p-value 0.05 to be considered statistically significant. 22 table was formulated for categorical variables including malreduction of syndesmosis and complications and were analysed to calculate relative risk and statistical significance using fishers exact test. Potential confounders incl uding age and duration since surgery were accounted for using regression analysis when analysing the correlation of syndesmosis malreduction with functional outcome scores.   As our primary outcome variable was accuracy of syndesmosis reduction based on syndesmotic width measured on axial CT scans, we also assessed intra-observer agreement for CT measurements using intra-class correlation coefficient (ICC) (80). The values for ICC range from 0.0 to 1.0 and can be interpreted as follows: 0-0.20 indicates poor agreement: 0.21-0.40 indicates fair agreement; 0.41-0.60 indicates moderate agreement; 0.61-0.80 indicates strong agreement; and 0.80 indicates almost perfect agreement. 2.5. Data protection The study was approved by the institutional review board and due consideration was given to data protection rules (appendix ivii). Patients were fully informed about the purpose of the study and outcome measures using an information leaflet (appendix iv). All patients included in the study voluntarily signed an informed consent (appendix vi). Patients data was stored on electronic database using unique identification code making it completely anonymous for analysis and storage purpose. Research data will be retained for a minimum of 5 years after the publication of the research.   Chapter No. 3 R ESULTS 3. 1. Participants Of the 228 consecutive patients operated for ankle fractures during the study period of 2 years, 167 patients did not have any syndesmosis injury.   Sixty one patients had associated syndesmosis injuries and were potentially eligible for study inclusion. Six of those 61 patients were excluded on the basis of study exclusion criteria. One patient died before recruitment, 2 were visitors from abroad and were   uncontactable, 2 had compound injury and 1 had bilateral injuries to his ankles. Fifty five patients were finally eligible for the study and invited for participation. Forty nine consented for the study, 5 refused to participate in the study as they did not have any problem and thought a review is unnecessary. One more patient moved abroad by that time. Out of 49 patients who consented for the study, 3 more were not able make it to the appointment because of work commitments leaving 46 patients for final analysis who attended for final follow up and CT scan. 3.2. Patients demographics and injury classification Forty-six patients finally attended for the review, 23 in tightrope group and 23 in screw group. Mean age was 41.65 years (range 24 69 years) and 39.82 years (range 18 65 Table 3.1: Comparison of patients demographics and injury pattern between two groups Tightrope Group Syndesmosis Screw Group Total number 23 23 Gender Male 17 (74%) 16 (70%) Female 06 (26%) 07 (30%) Age(years) 41.65 (24 69) 39.82 (18 65) Side Right 08 (35%) 10 (43%) Left 15 (65%) 13 (57%) Mechanism of injury Sports 5 (21.7%) 6 (26.1%) Fall from height 6 (26.1%) 3 (13.1%) Trip and fall 9 (39.1%) 7 (30.4%) Slipped on ice 3 (13.1%) 5 (21.7%) Dancing 0 2 (08.7%) Classification Weber B (SER) 02 (08.7%) 02 (08.7%) Weber C (PER) 13 (56.5%) 15 (65.2%) Maisennouve 08 (34.8%) 06 (26.1%) Number of fixations Single 16 20 Double 7 3 years) respectively in each groups. There were 17 (74%) male and 6 (26%) female in tightrope group while screw group had 16 (70%) male and 7 (30%) female. Right ankle was operated in 8 (35%) in tightrope group and 10 (43%) in screw group while left ankle was operated in 15 (65%) and 13 (57%) patients respectively.   There were 2 weber B fractures, 13 weber C and 8 Maisennouve fractures in tightrope group while 2 weber B, 15 weber C and 6 Maisennouve fractures in screw group. In tightrope group single tightrope was used in 16 patients while two tightropes were used in 7 patients. In screw group 20 patients had single syndesmosis screw while 3 patients required double screw fixation. Mean follow up was 30.2 months (range 18 41 months) in tightrope group and 29 months (range 18 41 months) in syndesmosis screw group. 3.3. Computed Tomographic measurements Measurements for the normal tibiofibular syndesmosis are summarized in [Table 3.2]. Mean tibiofibular width in normal ankles were 2.85 mm (range 1.9 4.4mm), anteriorly and 4.03 mm (2.2 6.3mm), posteriorly. In men the mean anterior width was 2.7 mm and posterior width was 4.12 while in women mean width was 3.23 mm anteriorly and 3.81 mm posteriorly. The measurements were performed twice in random order at least two weeks apart and analysed for intra-observer agreement. The intra-class correlation coefficient value was 0.91 for the two measurements. Comparison of syndesmosis width between normal and operated ankle showed mean values of 4.04 + 0.95 mm for normal side and 4.37 + 1.12 mm for operated side in tightrope group ( p = 0.30, t-test). In syndesmosis screw group the mean width of syndesmosis was measured as 4.02 +0.87 mm on the normal side and 5.16 + 1.92 mm on the operated side ( p = 0.01, t-test) [Table 3.3] [Fig. 3.2].

The primary outcome measure, malreduction of syndesmosis was diagnosed on the basis of pre-defined criteria of 2 mm difference from the normal side [Table 3.4]. There was no case of malreduction in tightrope group as compared to 5 (21.7%) cases of malreduction out of 23 cases of syndesmosis screw fixation (p 0.05, Fishers exact test) [Fig. 3.3]. Risk of malreduction was 21.7% higher in screw group than tightrope group. 3.4. Radiographic measurements Radiographic parameters of syndesmosis integrity were measured on standard AP radiograph of ankle 1 cm above the tibial plafond. Mean pre operative and post operative values are compared in [Table 3.5] [Fig. 3.4]. Mean post operative medial clear space (MCS) was 3.36 + 0.5 mm in tightrope group and 3.23 + 0.6 mm in syndesmosis screw group (p = 0.48). In tightrope group the mean post operative tibiofibular clear space (TFCS) was 4.04 + 0.8 mm as compared to 5.0 + 1.8 mm in screw group (p 0.05) while mean tibiofibular overlap (TFOL) was 8.21 + 2.0 mm and 7.47 + 2.0 mm respectively (p = 0.22).

Only 3 patients with true malreduction on CT scan were correctly diagnosed using radiographic parameters while 6 had a false positive result [Table 3.6]. Table 3.6: Comparison of CT scan and radiographs for diagnosis of syndesmosis malreduction Malreduction on CT scan Malreduction on radiographs Total No Yes No 35 6 41 Yes 2 3 5 Total 37 9 46 The radiographic criteria for syndesmosis malreduction included TFCS 6 mm or TFOL 6 mm on standard AP ankle radiographs. On CT scans malreduction was diagnosed if there was 2 mm difference in the width of syndesmosis as compared with normal side. 3.5. Clinical outcomes Mean time to full weight bearing was 8 + 1.2 (range 6 10) weeks in tightrope group as compared to 9.1 + 1.8 (range 6 13) weeks in screw group (p = 0.11) [Fig. 3.5]. Mean American orthopaedic foot and ankle society (AOFAS) hind foot score was 89.56 + 8.6 (95% CI 85.83 93.29) in tightrope group and 86.52 + 9.6 (95% CI 82.34 90.70) in screw group (p = 0.26). Similarly foot and ankle disability index (FADI) score was 82.42 + 11.2 (95% CI 77.56 87.27) in tightrope group and 81.22 + 15.6 (95%CI 74.46 87.97) in screw group (p = 0.76) [Table 3.6]. Both functional scores were measured on a scale of 0 100 with higher scores associated with better functional outcomes. None of the clinical outcome measures differ significantly between the two groups ( t -test) [Fig. 3.6]. Table 3.6: Clinical outcomes Tightrope group Syndesmosis screw group p value Time to full weight bearing 8.0 + 1.2 weeks (6 10) 9.1 + 1.8 weeks (6 13) p = 0.11 AOFAS Score 89.56 + 8.6 (69 100) 86.52 + 9.6 (65 100) p =0.26 (95%CI 85.83 93.29) (95%CI 82.34 90.70) FADI Score 82.42 + 11.2 (58.7 97.1) 81.22 + 15.6 (47.1 98.1) p =0.76 (95%CI 77.56 87.27) (95%CI 74.46 87.97) Regression analysis was performed to find any significant correlation between the two groups and the clinical outcome score (AOFAS) while adjusting for potential confounders [Table 3.7]. Type of fixation was not significantly associated with the clinical outcome score. Malreduction of syndesmosis on CT scan was the only variable that reached statistical significance when keeping other variables constant with regression coefficient -12.39; t = 2.43 and p 0.05 [Table 3.7].

Chapter No. 4 D ISCUSSION In this study we compared the accuracy and maintenance of syndesmosis reduction, based on computed tomographic scans and its correlation with the clinical outcomes. This study showed that there was significant difference in the mean width of syndesmosis between operated and normal ankles in screw group as compared with tightrope group. Students t-test was used to compare the means between operated and normal ankles. The p value for screw group was 0.01 as compared to 0.30 in tightrope group confirming that the results were statistically significant. According to our criteria of malreduction there were 5 cases of malreduction in screw group while none of the tightrope group showed malreduction. There was 21.7% increased risk of syndesmosis being malreduced when treated with screw fixation rather than tightrope technique (p 0.05, Fishers exact test). This is in accordance with previous literature regarding syndesmosis screw fixation. The incidence of malreduction of syndesmosis has b een reported between 16% and 52% (44, 50, 60, 81) . Weening et al (44) reported 16% of malreduction of syndesmosis in patients treated with syndesmosis screw. The diagnosis of malreduction in that study was based on standard radiographic parameters of syndesmosis integrity and demonstrated a direct relation of malreduction with poor functional outcome scores. As the literature has suggested that the standard radiographic measurements are not accurate (7, 39, 82, 83) and sufficient to diagnose syndesmotic malreduction, several authors has used CT scans for this purpose. Gardner et al (60) has reported 52% of syndesmosis malreduction in there series of 25 patients treated with syndesmosis screw based on CT scans as compared to only 24% using   standard radiographic criteria. This is the highest incidence of malreduction, reported so far in the literature but the validity of the results is limited by the lack of comparison with the uninjured ankle and the lack of clinical correl ation. Furthermore they considered the difference of more than 2 mm between anterior and posterior measurement of syndesmosis as significant for the diagnosis of malreduction. This criterion is questionable as Elgafy et al (12) has demonstrated in their study of CT measurements of normal ankle syndesmosis that the mean difference in the anterior and posterior width of syndesmosis was 2 mm. When comparing male and female separately the mean difference was 3 mm for male and 2 mm for female (12) . Our study also showed similar variations in anterior and posterior width of syndesmosis. The mean difference was 1.2 mm (range 0 3.3 mm) with wider difference in males than females on normal uninjured side [Table 3.2]. Considering the magnitude of normal variations, Gardner et al probably over estimated the incidence of malreduction in their study. Wikeroy et al (50) reviewed 48 patients treated with syndesmosis screw from an earlier randomised controlled study after 8.4 years and also repor ted 20.8% incidence of malreduction based on axial CT scan when comparing with normal side. Similar to Wikeroy et al our study showed 21.7% incidence of malreduction in screw group. Radiographic criteria of syndesmosis integrity as described by Harper et al (38) is routinely used in practice to diagnose syndesmosis diastasis despite several reports questioning the accuracy of those parameters . Our study showed no significant difference between the two groups regarding medial clear space (MCS) (p = 0.48) and tibiofibular overlap (TFOL) (p = 0.22) using t-test . Tibiofibular clear space was although significantly wider in screw group than tightrope group (p 0.05, t-test ). When radiographic parameters were used to diagnose diastasis there were nine cases of malreduction but did not correlate well with the CT diagnosis. Three out of five of the true malreductions were correctly diagnosed by radiographs while there were six false positive. This also confirms the findings of previous studies (7, 39, 82, 83) . Although, there was a trend towards better clinical outcomes in tightrope group but when adjusted for potential confounders such as age and duration since surgery there was no statistically significant difference in time to full weight bearing and functional outcome scores (AOFAS, FADI). Malreduction of the syndesmosis was the only independent variable which significantly affected the functional outcome scores. Similar findings were also reported by weening et al (44) and Wikeroy et al (50) . Accurate reduction of syndesmosis is essential to restore normal biomechanics of ankle joint. Malreduction leads to mismatch in tibial and talar articular surfaces and significantly reduce the contact area and increase the joint reaction forces which can results in early arthrosis and long term morbidity. Tightrope fixation for syndesmosis injury is a relatively new technique which provides dynamic fixation and obviates the need for routine removal of implant. So far the literature is limited regarding Tightrope and mainly comprises of few case series and nonrandomised comparative studies with limited number of patients and shorter follow up. Thornes et al (71) and Cottom et al (73) compared Tightrope and syndesmosis screw fixation in non randomized comparative study and reported a trend towards better functional outcomes. Thornes et al also performed CT scan in 11 out of 16 patients in Tightrope group after three months and did not find any loss of reduction. None of the syndesmosis screw group had a CT scan limiting the significance of that part of the study. Coetzee et al (76) reported similar trend of better clinical outcomes in there preliminary results of a randomized controlled trail. Earlier studies did not report any complication with this technique but later it has become e vident that like any novel technique there is a learning curve and cases of hardware removal has been reported in few studies due to soft tissue irritation over the lateral knot (75-77) . We did not have any complication in Tightrope group requiring hardware removal. In all our cases of tightrope fixation great care was taken to bury the knot deep. We created a periosteal recess at the posterior aspect of fibula before inserting the Tightrope and the knot was buried sub-periosteally. Theoretically, this technique might have helped in reducing the soft tissue irritation over the lateral knot but the association could be just incidental and no hard evidence can be provided on the basis of this study. So far this is on the only study that compared the accuracy and maintenance of syndesmosis reduction between Tightrope and syndesmosis screw group and showed that Tightrope fixation was significantly better in maintaining the reduction even after a mean duration of 30 months post surgery. The reason for high incidence of malreduction in syndesmosis screw group is hard to determine from this study as CT scans were not performed immediately post operatively which make it hard to discern at which time the diastasis occurred. Whether the syndesmoses were malreduced at the time of surgery or evolved over time. The possibility of increased gap after removal of syndesmosis screw cannot be ruled out. On the other hand Tightrope doesnt require routine removal and thus continue to maintain reduction. As Tightrope is a flexible device one possible explanation of accurate reduction is that fibula is pulled into the concave incisura of distal tibia as it is tightened. There are several limitations in this study. Firstly, this is a non randomized study and the treatment choice was based on the consultants preference. As no other variable influenced the choice of fixation, the demographics and the injury pattern in the two groups were comparable. Secondly, it is not possible to identify exactly the reason for higher incidence of malreduction in screw group. It was also not possible to blind the assessor for radiographic and CT measurements as it was obvious which group they belong. To reduce the measurement bias all the measurements were performed by an independent Musculoskeletal Radiologist. CT measurements were repeated at an interval of two weeks in random order, without the knowledge of previous measurements. Intra-class correlation coefficient of 0.91 showed high level of intra observer concordance. Clinical assessment and interviews were performed by an independent assessor who was blinded to the group of patients and two functional outcome scores one clinician reported (AOFAS) and other patient reported (FADI) were used to increase the validity. Despite these limitations, considering the appropriate sample size and follow up duration the results of the study are valid and show that Tightrope fixation is at least equivalent to the conventional screw fixation for the treatment of syndesmosis injuries with potential advantages of providing and maintaining accurate reduction and avoiding need for routine removal. The technique is simple and can be used both in isolation and with plate fixation. It minimise the risk of hardware complication associated with screw fixation and the need for second operation. Like any novel technique, there is a learning curve and care must be taken to avoid soft tissue complications that may require implant removal. Further long term randomized controlled trials would be helpful in clarifying the issue.  Ãƒâ€šÃ‚   Chapter No. 5 C ONCLUSION Ankle syndesmosis injuries are complex and require accurate reduction and fixation to restore normal biomechanics of ankle joint and avoid long term complications. Syndesmosis screw and Tightrope fixation are both valid options for the treatment of syndesmosis injuries. Although, short to medium term clinical results were comparable for both the groups, Tightrope provides and maintains more accurate reduction of syndesmosis as compared to screw fixation and obviates the need for routine removal of implant. The radiographic parameters of syndesmosis integrity routinely used are inaccurate and care must be taken to appropriately reduce the syndesmosis before fixation as malreduction of syndesmosis is the most important independent predictor of long term functional outcome.
