Epidemiology and management of ankle sprain injuries over seven seasons in an elite professional ballet company.

OBJECTIVES: To investigate the epidemiology and management of ankle ligament sprains over seven seasons in a professional ballet company. DESIGN: Descriptive epidemiology study. METHODS: Medical attention injury, time-loss injury, and exposure data pertaining to 140 professional ballet dancers were prospectively recorded by Chartered Physiotherapists over seven seasons (2015/16-2021/22); a period including the COVID-19 global pandemic. RESULTS: Sixty-nine ankle sprains (46 time-loss) in 45 dancers (32 %) were recorded: 51 sprains were classified as grade I, 15 were classified as grade II, and three were classified as grade III; 53 sprains affected only one ligament, whilst 16 were multi-ligament sprains. For time-loss injuries, median time-loss durations varied by grading (I - 31 days, II - 54 days, and III - 147 days) and the number of ligaments affected (one - 31 days, two - 54 days, three - 134 days, four - 137 days), with time-loss ranging from 1 to 188 days. Of the 46 time-loss ankle sprains, eight were mild, nine were moderate, and 29 were severe. The incidence rate (injuries·1000 h-1) of medical attention ankle sprains was 0.073 (95 % CI: 0.046 to 0.117) in male dancers and 0.101 (95 % CI: 0.069 to 0.148) in female dancers, and the incidence of time-loss ankle sprains was 0.044 (95 % CI: 0.024 to 0.080) in male dancers and 0.064 (95 % CI: 0.040 to 0.103) in female dancers. No significant effect of sex was observed on either medical attention (p = .304) or time-loss (p = .327) ankle sprain incidence rates. Ten percent of dancers sustained multiple sprains across the seven seasons. Fifty and 39 % of ankle sprains in female and male dancers, respectively, were preceded by a history of ankle sprains. Jumping and landing (30 sprains) and non-dance movements (16 sprains) were the most common inciting movements. Bone bruising and synovitis were the most common concurrent pathologies. CONCLUSIONS: Ankle sprains placed a considerable burden on the ballet company studied. These time-loss durations specified by number and grade of ligament sprain, injury history, and secondary pathologies can guide return-to-dance rehabilitation pathways.

Analysis of medical services provided to patients with ankle sprains in Korea between 2015 and 2017: a cross-sectional study of the health insurance review and assessment service national patient sample database.

OBJECTIVES: To provide useful information for policy-makers and clinicians by analysing the medical service use-divided into Western medicine (WM) and Korean medicine (KM)-of patients with ankle sprains in South Korea between 2015 and 2017. DESIGN: Cross-sectional, retrospective, observational study. SETTING: Tertiary hospitals, WM hospitals, WM clinics, KM hospitals, KM clinics and others in South Korea. PARTICIPANTS: We analysed claim data and patient information from the 2015 to 2017 Health Insurance Review and Assessment National Patient Sample (HIRA-NPS) dataset, including 151 415 patients diagnosed with a 'dislocation, sprain and strain of joints and ligaments at ankle and foot level' (10th revision of the International Statistical Classification of Diseases code S93) who used medical services at least once in 3 years between January 2015 and December 2017 in South Korea. PRIMARY AND SECONDARY OUTCOME MEASURES: Cost of medical care, number of consultations, type of institution visited, types of treatment. RESULTS: There were 160 200 consultations and 53 044 patients in 2015, 149 956 consultations and 50 830 patients in 2016 and 140 651 consultations and 47 541 patients in 2017. The total treatment costs were US$3 355 044.21, US$3 245 827.70 and US$3 128 938.46 in 2015, 2016 and 2017, respectively. The most common age was 10-19 years. The most frequent type of visit was KM outpatient visit (56%). Physiotherapy was most common in WM outpatient visits, while acupuncture was most common in KM visits. Most patients used one institution, rather than alternating between WM and KM. CONCLUSIONS: By identifying the trends and costs of treatment methods used for ankle sprains and comparing WM and KM, our data provide basic information for future health policy-making. In addition, the duality of the Korean medical system is highlighted as a possible cause of increased costs.

A qualitative study of health professions curricula and management of lateral ankle ligament sprain demonstrates inconsistency.

BACKGROUND: Health educators aim to graduate students who are safe, effective and practice evidence-based medicine (EBM). Clinical Practice Guidelines (CPGs) are tools for translating evidence into clinical practice for health professionals and educators who lack time to appraise the evidence. There have been CPGs published for lateral ankle ligament sprains (LALS) for physiotherapists, nurses, and doctors. Clinical decision rules have also been developed for LALS to increase the safety of practice. The Ottawa Ankle Rules (OAR) were developed to screen for the need for an x-ray following an ankle or foot injury. METHODS: Educators from the Australasian College of Sports and Exercise Physicians (ACSEP), St John Ambulance first aiders, pharmacy, nursing, and physiotherapy disciplines were participants in this study. Using purposeful sampling with semi-structured questions and a LALS case study, 19 Australian educators were interviewed. Curricula and textbooks were also collected and analysed. Two researchers independently analysed the data using a deductive method. RESULTS: Analysis found that no educator used a CPG to inform their teaching. There was no common LALS curriculum for the five groups studied. There were two approaches: a triage curriculum (St John Ambulance, pharmacy, nursing) and a reflective curriculum (ASCEP and physiotherapy). Textbooks influenced curriculum for physiotherapy, pharmacy and first aid educators. The triage curricula recommend rest, ice, compression and elevation (RICE) alone, while the reflective curricula uses OAR, RICE, immobilisation if the LALS is severe, functional support (brace), exercises and manual therapy. In addition, ACSEP and physiotherapy do not recommend electrotherapy. All five groups were cautious about the use of non-steroidal anti-inflammatory drugs (NSAIDs). CONCLUSIONS: Physiotherapy and ACSEP educators teach OAR. Despite not using the CPGs to inform curriculum, physiotherapy and ACSEP have unintentionally aligned their curriculum with current LALS CPG recommendations. However, nursing, pharmacy and first aid trainers are not teaching OAR or aligned with LALS CPGs. Educators in pharmacy, nursing and first aid should re-examine their curricula and consider possibly teaching OAR and using CPG. Clinical practice guideline developers should consider pharmacists and first aiders as users of their LALS CPGs.

Acupuncture for the treatment of ankle sprain: A protocol for a systematic review and meta-analysis: study protocol.

BACKGROUND: Ankle sprain is one of the most common musculoskeletal injuries in our daily life, which may lead to chronic ankle instability, reducing the quality of patients' life and imposing a heavy burden on social medical security system. There are many kinds of methods treating ankle sprain, which can be divided into the conservative treatments and surgical intervention. Acupuncture is one of the conservative treatments for ankle sprain, especially in China. Therefore, we perform a systematic review and meta-analysis to evaluate the evidence for acupuncture's effectiveness, safety and cost benefits for the treatment. METHODS: For the acquisition of required data of eligible randomized controlled trials (RCTs), literature search will be undertaken from the following database: PubMed, Embase, Web of Science, The Cochrane Library, Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov, Chinese National Knowledge Infrastructure (CNKI), VIP Database, and Wanfang database. Quality assessment of the included studies will be independently performed according to the Cochrane Risk of Bias Tool by 2 investigators and the level of evidence for results will be assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method. Statistical analysis will be conducted with Revman 5.3. RESULTS: From the study we will assess the effectiveness, safety and cost benefit of acupuncture on pain relief and functional improvement in patients with ankle sprain. CONCLUSION: The conclusion of this study will provide evidence to ensure the effectiveness, safety and cost benefits of acupuncture on ankle sprain, which can further guide the selection of appropriate interventions.

The health economics of ankle and foot sprains and fractures: A systematic review of English-language published papers. Part 1: Overview and critical appraisal.

BACKGROUND: Ankle and foot sprains and fractures are common injuries affecting many individuals, often requiring considerable and costly medical interventions. The objectives of this systematic review are to collect, assess, and critically appraise the published literature on the health economics of ankle and foot injury (sprain and fracture) treatment. METHODS: A systematic literature review of Ovid MEDLINE, EMBASE, Cochrane DSR, ACP Journal Club, AMED, Ovid Healthstar, and CINAHL was conducted for English-language studies on the costs of treating ankle and foot sprains and fractures published from January 1980 to December 2014. Two reviewers assessed the articles for study quality and abstracted data. RESULTS: The literature search identified 2047 studies of which 32 were analyzed. A majority of the studies were published in the last decade. A number of the studies did not report full economic information, including the sources of the direct and indirect costs, as suggested in the guidelines. The perspective used in the analysis was missing in numerous studies, as was the follow-up time period of participants. Only five of the studies undertook a sensitivity analysis which is required whenever there are uncertainties regarding cost data. CONCLUSION: This systematic review found that publications do not consistently report on the components of health economics methodology, which in turn limits the quality of information. Future studies undertaking economic evaluations should ensure that their methods are transparent and understandable so as to yield accurate interpretation for assistance in forthcoming economic evaluations and policy decision-making.

The health economics of ankle and foot sprains and fractures: A systematic review of English-language published papers. Part 2: The direct and indirect costs of injury.

BACKGROUND: Ankle and foot sprains and fractures are prevalent injuries, which may result in substantial physical and economic consequences for the patient and place a financial burden on the health care system. Therefore, the objectives of this paper are to examine the direct and indirect costs of treating ankle and foot injuries (sprains, dislocations, fractures), as well as to provide an overview of the outcomes of full economic analyses of different treatment strategies. METHODS: A systematic review was carried out among seven databases to identify English language publications on the health economics of ankle and foot injury treatment published between 1980 and 2014. The direct and indirect costs were abstracted by two independent reviewers. All costs were adjusted for inflation and reported in 2016 US dollars (USD). RESULTS: Among 2047 identified studies, 32 were selected for analysis. The direct costs of ankle sprain management ranged from $292 to $2268 per patient (2016 USD), depending on the injury severity and treatment strategy. The direct costs of managing ankle fractures were higher ($1908-$19,555). Foot fracture treatment had similar direct costs ranging from $998 to $21,801. The economic evaluations were conducted from the societal or payer's perspectives. CONCLUSION: The costs of treating ankle and foot sprains and fractures varied among the studies, mostly due to differences in injury type and study characteristics, which impacted the ability of directly comparing the financial burden of treatment. Nonetheless, the review showed that the costs experienced by the patient and the health care system increased with injury complexity.

Assessment of orthotic needs in Iranian veterans with ankle and foot disorders.

BACKGROUND: War-related traumas can lead to orthopedic and neurological disorders in victims. However, the scope of such disorders may expand months or even years after the trauma. Orthotic treatment as a rehabilitation process aims to enable people with disabilities to reach and maintain their optimal physical, sensory, intellectual, psychological, and social functional levels. This study aimed to investigate the rate of using orthoses among Iranian veterans with neuromuscular and skeletal disorders of the ankle and foot. Furthermore, the priorities of orthotic treatment in those veterans were explored. METHODS: This qualitative study was a national health needs assessment conducted in 11 provinces of Iran during 2011-2016. A stakeholder research group was established to survey the veterans in respect to their demographic variables, activities of daily living, current health conditions, and rate of using orthoses. RESULTS: Overall, 907 of the 1124 veteran participants completed the survey (response rate: 80.7%). Most of the veterans were men (97.7%), and their age and disability rate were 52.07 ± 8.13 years and 31.92% ± 14.93%, respectively. Nearly 42% of the veterans had experience in using orthoses on a daily and weekly basis. As physical ambulation was the main problematic activity in veterans, most of them were using medical shoes and foot orthoses. Nearly 37% of veterans were in need of some type of lower limb orthoses on the contralateral side to compensate for their hip inequality. In sequential order, the most in need orthoses for veterans were foot orthoses (n = 538), medical shoes (n = 447), lower limb orthoses on the contralateral side (n = 320), spinal orthoses (n = 273), and upper limb orthoses (n = 86). CONCLUSIONS: In spite of the high demands for orthoses among Iranian veterans with ankle and foot disorders, the use of orthoses is insufficient. Hence, there is a discrepancy between the current rate of orthoses use and its ideal situation, and more resources should be provided for service providers to be able to serve veterans. Moreover, veterans should be educated regarding orthoses, their use, and their impacts on the user's health status. The findings of a needs assessment of orthoses can be used in strategic planning and decision making to improve health care services for Iranian veterans.

Cross-cultural adaptation and validation of Spanish version of The Foot and Ankle Ability Measures (FAAM-Sp).

BACKGROUND: The Foot and Ankle Ability Measure (FAAM) is a Patient Reported Outcome (PRO) commonly used to determine the effectiveness of therapeutic interventions for patients with foot and ankle pathologies and associated impairments of body function and structure, activity limitations, and participation restrictions. The aim of this study was to cross-culturally adapt the FAAM into Spanish. METHODS: Cross-cultural adaptation was performed according to the international guidelines of the International Society for Pharmacoeconomics and Outcomes Research. Cronbach's alpha, test re-test reliability, and item-total and inter-item correlations were analyzed. Confirmatory factor analysis (CFA) was carried out to test construct validity. Pearson correlations were calculated to assess the convergent validity between FAAM and EuroQol-5. RESULTS: Spanish data set comprised 194 patients, with a mean age of 38.45 (16.04) and 130 (67.1%) were female, seeing a podiatrist with a wide variety of foot and ankle related disorders. CFA was carried out to test structure matrix (which has three factors). The test-retest reliability was high with global ICC of 0.95 (95% CI: 0.93 to 0.98). A 15 items version of the FAAM-Sp Activities of Daily Living (ADL) obtained the best fit: relative chi-square (x2/df) of 2.46, GFI 0.90 CFI 0.95, NFI 0.93, and RMSEA 0.08 (90% CI 0.04 to 0.09). For exploratory factor analysis for the FAAM-Sp Sport, a one factor solution was obtained, which explained 76.70% of total variance. CFA corroborated this model with an excellent goodness of fit:: relative chi-square (x2/df) of 0.80, GFI 0.99 CFI 1.00, NFI 0.99, and RMSEA 0.00 (90% CI 0.00 to 0.75). CONCLUSIONS: This study validated a new 15-item FAAM-Sp ADL and FAAM-Sp Sport subscales, which can be used as a self-reported outcome measure in clinical practice and research for patients resident in Spain whose main language is Spanish.

Assessment of Relationships Between Joint Motion Quality and Postural Control in Patients With Chronic Ankle Joint Instability.

Study Design Controlled laboratory study, cross-sectional. Background Lateral ankle sprains are among the most common injuries encountered during athletic participation. Following the initial injury, there is an alarmingly high risk of reinjury and development of chronic ankle instability (CAI), which is dependent on a combination of factors, including sensorimotor deficits and changes in the biomechanical environment of the ankle joint. Objective To evaluate CAI-related disturbances in arthrokinematic motion quality and postural control and the relationships between them. Methods Sixty-three male subjects (31 with CAI and 32 healthy controls) were enrolled in the study. For arthrokinematic motion quality analysis, the vibroarthrographic signals were collected during ankle flexion/extension motion using an acceleration sensor and described by variability (variance of mean squares [VMS]), amplitude (mean of 4 maximal and 4 minimal values [R4]), and frequency (vibroarthrographic signal bands of 50 to 250 Hz [P1] and 250 to 450 Hz [P2]) parameters. Using the Biodex Balance System, single-leg dynamic balance was measured by overall, anteroposterior, and mediolateral stability indices. Results Values of vibroarthrographic parameters (VMS, R4, P1 and P2) were significantly higher in the CAI group than those in the control group (P<.01). Similar results were obtained for all postural control parameters (overall, anteroposterior, and mediolateral stability indices; P<.05). Moreover, correlations between the overall stability index and VMS, and P1 and P2, as well as between the anteroposterior stability index and P1 and P2, were observed in the CAI patient group, but not in controls. Conclusion In patients with CAI, deficits in both quality of ankle arthrokinematic motion and postural control were present. Therefore, physical therapy interventions focused on improving ankle neuromuscular control and arthrokinematic function are necessary in CAI patient care.

What priorities should be considered for Iranian veterans with ankle-foot injuries? A health needs assessment study, 25 years post-conflict.

Despite the passage of time, a large number of veterans are still affected by injuries acquired during Iran-Iraq war. In addition to their primary injuries, the majority of veterans also experience difficulty with long-term, secondary effects. Studies have shown that the most common of these include a range of disabilities, pain, and dramatic decline in mental health and quality of life. Improving living conditions and providing rehabilitation services to veterans has always been a main priority of authorities. The goal of this study was to explain the methods and materials with which these priorities were explored.

A critical evaluation of venous thromboembolism risk assessment models used in patients with lower limb cast immobilisation.

BACKGROUND: There is a recognised link between lower limb cast immobilisation and the development of venous thromboembolism (VTE). Our aim was to assess the diagnostic accuracy of risk assessment models (RAMs) applicable to this patient group. This has not been done before. METHODS: A literature and guideline review identified five RAMs. They were used to retrospectively risk assess a consecutive series of patients who were diagnosed with symptomatic VTE following lower limb injury treated with a cast (Group I). A case-matched cohort who did not suffer symptomatic VTE (Group II) was also retrospectively risk assessed. The RAMs' diagnostic performance indicators were calculated. RESULTS: Groups I and II consisted of 21 patients each. There was no significant difference in the mean age or total number of VTE risk factors between Groups I and II (p=.957 and p=.878 respectively). The Plymouth (2010) RAM achieved the highest accuracy (54.8%). CONCLUSIONS: Each RAM demonstrated significant limitations. Two displayed very limited clinical utility. Three recommended chemical thromboprophylaxis to all patients because they weighted lower limb immobilisation as an absolute risk factor for the development of VTE. Cast immobilisation should not be considered an absolute risk factor when risk assessing patients who all have casts. Prospective evaluation with a larger patient cohort is required.

The Mechanical Functionality of the EXO-L Ankle Brace: Assessment With a 3-Dimensional Computed Tomography Stress Test.

BACKGROUND: A new type of ankle brace (EXO-L) has recently been introduced. It is designed to limit the motion of most sprains without limiting other motions and to overcome problems such as skin irritation associated with taping or poor fit in the sports shoe. PURPOSE: To evaluate the claimed functionality of the new ankle brace in limiting only the motion of combined inversion and plantar flexion. STUDY DESIGN: Controlled laboratory study. METHODS: In 12 patients who received and used the new ankle brace, the mobility of the joints was measured with a highly accurate and objective in vivo 3-dimensional computed tomography (3D CT) stress test. Primary outcomes were the ranges of motion as expressed by helical axis rotations without and with the ankle brace between the following extreme positions: dorsiflexion to plantar flexion, and combined eversion and dorsiflexion to combined inversion and plantar flexion. Rotations were acquired for both talocrural and subtalar joints. A paired Student t test was performed to test the significance of the differences between the 2 conditions (P ≤ .05). RESULTS: The use of the ankle brace significantly restricted the rotation of motion from combined eversion and dorsiflexion to combined inversion and plantar flexion in both the talocrural (P = .004) and subtalar joints (P < .001). No significant differences were found in both joints for the motion from dorsiflexion to plantar flexion. CONCLUSION: The 3D CT stress test confirmed that under static and passive testing conditions, the new ankle brace limits the inversion-plantar flexion motion that is responsible for most ankle sprains without limiting plantar flexion or dorsiflexion. CLINICAL RELEVANCE: This test demonstrated its use in the objective evaluation of braces.

Cost Consequence Analysis of Implementing the Low Risk Ankle Rule in Emergency Departments.

STUDY OBJECTIVE: Implementation of the Low Risk Ankle Rule can safely reduce radiographs for children with acute ankle injuries. The main objective of this study is to examine the costs and consequences of implementing the rule. METHODS: For children aged 3 to 16 years and with an acute ankle injury, we collected data on health care provider visits, imaging, and treatment at the index emergency department (ED) visit and days 7 and 28 post-ED discharge. This was done during 3 consecutive 6-month phases at 6 EDs. After the baseline phase 1, the Low Risk Ankle Rule was introduced in phases 2 and 3 in 3 intervention EDs, but not in the 3 pair-matched control EDs. We compared the effect of the Low Risk Ankle Rule on health care and patient-paid costs, the proportion of radiographs ordered, the proportion of missed clinically important fractures, and the follow-up use of health care resources. RESULTS: We enrolled 2,151 children with ankle injuries, 1,055 at the intervention and 1,096 at the control EDs. Health care costs were $36.93 less per patient at intervention compared with control sites (P=.02). Out-of-pocket costs to the patients were $2.09 more per patient at intervention sites (P=.30). In intervention versus control sites, the main contributor to cost reduction was the 22.9% reduction in ankle radiography. Furthermore, there were no significant differences in the frequency of missed clinically important fractures (0.1% versus 0.9%) or follow-up use of health care resources. CONCLUSION: Widespread implementation of the Low Risk Ankle Rule may lead to reduction of unnecessary radiographs for children and result in cost savings.

The trAPP-study: cost-effectiveness of an unsupervised e-health supported neuromuscular training program for the treatment of acute ankle sprains in general practice: design of a randomized controlled trial.

BACKGROUND: Ankle sprains are one of the most frequent injuries of the musculoskeletal system, with yearly around 680.000 new sprains in The Netherlands. Of these, about 130.000 people will visit the general practitioner (GP) each year. In addition, patients have an increased risk of a recurrent ankle sprain and about a third report at least one re-sprain. No optimal treatment strategy has proven to be effective in general practice, however promising results were achieved in a preventive trial among athletes. Therefore, the objective is to examine the (cost)-effectiveness of an unsupervised e-health supported neuromuscular training program in combination with usual care in general practice compared to usual care alone in patients with acute ankle sprains in general practice. METHOD/DESIGN: This study is a multi-center, open-label randomized controlled trial, with a one-year follow-up. Patients with an acute lateral ankle sprain, aged between 14 and 65 years and visiting the GP within three weeks of injury are eligible for inclusion. Patients will be randomized in two study groups. The intervention group will receive, in addition to usual care, a standardized eight-week neuromuscular training program guided by an App. The control group will receive usual care in general practice alone. The primary outcome of this study is the total number of ankle sprain recurrences reported during one year follow-up. Secondary outcomes are subjective recovery after one year follow-up, pain at rest and during activity, function, return to sport, cost-effectiveness and compliance of the intervention. Measurements will take place monthly for the study period of 12 months after baseline measurement. DISCUSSION: For general practitioners the treatment of acute ankle sprains is a challenge. A neuromuscular training program that has proven to be effective for athletes might be a direct treatment tool for acute ankle sprains in general practice. Positive results of this randomized controlled trial can lead to changes in practice guidelines for general practitioners. In addition, since this training program is e-health supported, positive results can also lead to a novel way of injury prevention. TRIAL REGISTRATION: Dutch Trial Registration: NTR4765.

Musculoskeletal function assessment outcomes scores over time for tibial plafond (OTA/AO 43) and proximal humeral (OTA/AO 11) fractures: a pilot project.

OBJECTIVES: What is the return to function after an isolated proximal humerus or tibial plafond fracture? DESIGN: Prospective observational. SETTING: Orthopaedic outpatient clinics. PATIENTS/PARTICIPANTS: Consecutive patients were enrolled with isolated proximal humerus (N = 155) and tibial plafond fractures (N = 120). INTERVENTION: None. MAIN OUTCOME MEASUREMENTS: Musculoskeletal Function Assessment. RESULTS: Patients who sustained isolated proximal humerus or tibial plafond fractures showed gradual improvement over 1 year. Women consistently demonstrated greater dysfunction than men at 6, 9, and 12 months after tibial plafond fracture. Age had an impact on return to function after injury for both fractures. Younger patients (18-29 years) with either type of injury tended to have better scores compared with the older patients. CONCLUSIONS: Detailed analysis of this data demonstrates variation in patient-based outcomes during recovery from a proximal humerus or tibial plafond fracture. These data need to be reviewed in the context of the individual patient when following a patient's recovery. LEVEL OF EVIDENCE: Prognostic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Assessment of functional treatment versus plaster of Paris in the treatment of grade 1 and 2 lateral ankle sprains.

BACKGROUND: Despite the common occurrence of ankle sprains, no treatment is considered to be the gold standard for the management of such sprains. We assessed functional treatment versus plaster of Paris (POP) for the treatment of lateral ankle sprains, with pain and function employed as the outcome measures. MATERIALS AND METHODS: 126 Patients were eligible for inclusion. They were assigned to either the functional treatment Tubigrip (TG) group or the POP group after applying block randomization. Characteristics such as age, dominant ankle, and gender were assessed at baseline. Pain and functional assessments were done using the visual analog scale (VAS) and the Karlsson score (KS) at baseline (at the start of the study) and during the 2nd and 6th weeks, respectively. Data on other subjective parameters, such as the number of painkillers used, the number of days taken off work, and the number of sleepless nights, were requested from the patients at the end of the study. SPSS version 16 was used for analysis, and p < 0.05 was taken to indicate significance. RESULTS: 60 Patients completed the trial in each group. The mean ages were 28.77 ± 6.72 in the TG group and 29.83 ± 6.30 in the POP group (p = 0.034). There was a slight female predominance. Right and left ankles were equally involved in the TG group, while left ankles were mainly involved in the POP group. Mean differences in VAS and KS between the two groups were statistically significant at the end of the study. The mean number of painkillers used by the patients in the TG group was higher than the number used in the POP group (p < 0.001). The mean number of days taken off work was 4.18 ± 1.73 days in the TG group, and 6.25 ± 2.73 days in the POP group (p < 0.001). The mean number of sleepless nights was higher in the POP group. CONCLUSION: The results of our study indicate that functional treatment provides better functional support and pain reduction than a below-knee POP cast. LEVEL OF EVIDENCE: Level I.

Assessment of Bosworth-type fracture by external oblique radiographs.

INTRODUCTION: Bosworth described an unusual fracture dislocation of the ankle with fixed posterior fracture dislocation of the fibula. This ankle fracture variant is often not recognized in initial radiographs and requires a computed tomographic scan for verification. It is usually not reducible by the closed method, and repeated trials induce more damage. The purpose of this study was to verify the usefulness of simple external oblique radiographs for diagnosis of Bosworth-type fracture. METHODS: We reviewed the 327 patients who were diagnosed as unilateral malleolus ankle fracture in 2002 to 2012. Four cases of Bosworth-type fracture were identified. External oblique radiograph was taken initially, immediately after first closed reduction, and after open reduction (3 phases) was undertaken to check the position of fibula in relation with the talus. Fifty cases of bimalleolar fractures and unaffected ankle were compared. Longitudinal bisecting line along the proximal fibula was drawn, and the talus was divided in 2 parts. Anterior and posterior part of the talus was defined as part α and ß. The ratio resulted from dividing α with (α + ß) implies the fibula position relative to the talus. RESULTS: Mean α/(α + ß) ratio of each phase were 0.4994, 0.4891, 0.2875, 0.2698, and 0.2709. There was significant difference in initial and first reduction phase of Bosworth-type fracture than other groups (P = < .0001). There was no significant difference in open reduced Bosworth-type fracture with bimalleolar fractures and unaffected ankles (P = .528, .602). CONCLUSIONS: An external oblique radiograph provides useful information that can differentiate Bosworth-type fracture from other reducible bimalleolar fractures.

Assessment and management of patients with ankle injuries.

Foot and ankle injuries are common and can have a significant effect on an individual's daily activities. Nurses have an important role in the assessment, management, ongoing care and support of patients with ankle injuries. An understanding of the anatomy and physiology of the ankle enables nurses to identify significant injuries, which may result in serious complications, and communicate effectively with the multidisciplinary team to improve patient care and outcomes.

Epidemiology, management, and outcome of sport-related ankle fractures in a standard UK population.

BACKGROUND: The literature on the outcome of sport-related ankle fractures has focused on operatively managed fractures, despite a large proportion being treated nonoperatively. We describe the epidemiology, management, and outcome of acute sport-related ankle fractures in a UK population. METHODS: All sport-related ankle fractures sustained during 2007 to 2008 in the Lothian Population were prospectively collected when patients attended the only adult orthopaedic service in Lothian. Fractures were classified using the Lauge Hansen and the Pott's Classification. The presence of fracture displacement was also recorded. Patients were contacted in February 2011 to ascertain their progress in return to sport. RESULTS: Ninety-six sport-related ankle fractures were recorded in 96 patients. Eighty-four fractures (88%) were followed up at a mean interval of 36 months (range, 30-42). Most common associated sports were soccer (n = 49), rugby (n = 15), running (n = 5), and ice skating (n = 3). The mean time for return to sport was 26 weeks (range, 4-104), the return rate to sport 94%, and the persisting symptom rate 42%. Fifty-two fractures (all nondisplaced) were managed nonoperatively-43 isolated lateral malleolar (30 Weber B, 13 Weber A), 2 isolated medial malleolar, 7 bimalleolar. Forty-four fractures were managed operatively-42 were displaced (2 isolated lateral malleolar, 3 isolated medial malleolar, 18 bimalleolar equivalent, 9 bimalleolar, 3 trimalleolar equivalent, 7 trimalleolar), 2 were un-displaced (2 trimalleolar). The mean times for return to sport were 20 weeks (range, 4-52) for the nonoperative cohort (NOC) and 35 weeks (range, 8-104) for the operative cohort (OC) (P < .001), the return rates to sport were 100% for NOC and 87% for OC (P < .016), and the persisting symptom rates were 17% for NOC and 71% for OC (P < .001). CONCLUSIONS: Nondisplaced ankle fractures in athletes were successfully managed with nonoperative care. They had greater return rates to sport, quicker return times, and lower persisting symptom rates but had less severe injuries. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Health care consumption and costs due to foot and ankle injuries in the Netherlands, 1986-2010.

BACKGROUND: Foot and ankle injuries account for a large proportion of Emergency Department attendance. The aim of this study was to assess population-based trends in attendances due to foot and ankle injuries in the Netherlands since 1986, and to provide a detailed analysis of health care costs in these patients. METHODS: Age- and gender-standardized emergency attendance rates and incidence rates for hospital admission were calculated for each year of the study. Injury cases and hospital length of stay were extracted from the National Injury Surveillance System (non-hospitalized patients) and the National Medical Registration (hospitalized patients). Data were grouped into osseous and ligamentous injuries for foot and ankle separately. An incidence-based cost model was applied to calculate associated direct health care costs. RESULTS: Since 1986 the overall emergency attendance rate decreased from 858 to 640 per 100,000 person years. In non-admitted patients (90% of cases), ligamentous injuries approximately halved, whereas osseous injuries increased by 28% (foot) and 25% (ankle). The incidence rate for hospital admission increased by 35%, mainly due to an almost doubling of osseous injuries. Attendance rates showed a peak in adolescents and adults until ~45 years of age in males and (less pronounced) in females. The total number of hospital days decreased to 58,708 days in 2010. Hospital length of stay (HLOS) increased with age and was highest for osseous injuries. HLOS was unaffected by gender, apart for longer stay in elderly females with an osseous ankle injury. Health care costs per case were highest for osseous injuries of the ankle (€ 3,461). Costs were higher for females and increased with age to € 6,023 in elderly males and € 10,949 in elderly females. Main cost determinants were in-hospital care (56% of total costs), rehabilitation/nursing care (15%), and physical therapy (12%). CONCLUSIONS: Since 1986, the emergency attendance rate of foot and ankle injuries in the Netherlands decreased by 25%. Throughout the years, the attendance rate of (relatively simple) ligamentous injuries strongly reduced, whereas osseous injuries nearly doubled. Attendance rates and health care costs were gender- and age-related. Main cost determinants were in-hospital care, rehabilitation/nursing care, and physical therapy.
