Disparities in concussion diagnoses compared to ankle injuries.

BACKGROUND: Health disparities related to concussions have been reported in the literature for certain minority populations. Given the significant impact of concussions on long- and short-term function, the mitigation of barriers to accessing care is an important public health objective. OBJECTIVE: To determine if racial and ethnic disparities exist in patients who seek care for concussions compared to a control group with orthopedic ankle injuries (sprains and fractures) to minimize confounding factors that predispose to injury. DESIGN: Cohort study. SETTING: Single institution between February 2016 and December 2020. PATIENTS: A retrospective review of electronic medical records was completed for patients with International Classification of Diseases, Tenth Revision (ICD-10) diagnosis codes for concussion, ankle sprain, and ankle fracture. A total of 10,312 patients were identified: 1568 (15.2%) with concussion, 4871 (47.3%) with ankle sprain, and 3863 (37.5%) with ankle fracture. INTERVENTIONS: Patients were stratified by demographic factors, including sex, ethnicity, race, and insurance type. MAIN OUTCOME MEASURES: Diagnosis of concussion. RESULTS: The concussion group was the youngest (28.3 years ± 18.0) and had the fewest females (53.1%) compared to the ankle sprain (35.1 years ± 19.7; 58.7%) and fracture groups (44.1 years ± 21.3; 57.3%). The concussion group had a smaller proportion of Hispanic patients than the ankle sprain group (odds ratio [OR] 0.71, 95% confidence interval [CI] 0.55-0.92, p = .010) and fracture group (OR 0.58, 95% CI 0.44-0.75, p = <.001). In addition, the concussion group was less likely to be Asian (OR 0.70, CI 0.52-0.95, p = .023) than the sprain group and less likely to be Black/African American than both sprain (OR 0.65, 95% CI 0.46-0.93, p = .017) and fracture groups (OR 0.62, 95% CI 0.43-0.89, p = .010). There were no differences across racial groups between ankle sprains and fractures. Patients with Medicaid/Medicare and self-pay had a higher likelihood of being in the concussion group than those with private insurance. CONCLUSION: Differences in concussion diagnosis may exist between certain demographic groups compared to those with ankle injuries. Efforts to mitigate disparities in concussion care are worthwhile with a focus on patient and caregiver education.

Epidemiology of Ankle Sprain in the Active-Duty Military Population.

¼: Ankle sprain is one of the most prevalent injuries within the military population, resulting in health-care costs, time away from active duty, and negative impacts on overall readiness. ¼: Female service members appear to be more likely to sustain ankle sprains than male service members. ¼: There is a need for additional research on prevention methods and rehabilitation programs for ankle sprains in the military population because the rate of ankle sprain in this population exceeds that in populations with less physically demanding lifestyles. Consequently, low-cost prevention strategies could yield substantial benefits.

Assessment and management of adult ankle fractures: understanding the evidence.

Ankle fractures are a common injury. Assessment should include looking at the mechanism of injury, comorbidities, associated injuries, soft tissue status and neurovascular status. Emergent reduction is required for clinically deformed ankles. Investigations should include plain radiographs and a computed tomography scan for more complex injuries or those with posterior malleolus involvement. An assessment of ankle stability determines treatment, taking into account comorbidities and preoperative mobility which need special consideration. Non-operative management includes splint or cast, allowing for early weightbearing when the ankle is stable. Operative management includes open reduction and internal fixation, intramedullary nailing (of the fibula and hindfoot) and external fixation. Syndemosis stabilisation includes suture button or screw fixation. The aim of treatment is to restore ankle stability and this article explores the current evidence in best practice.

Insurance Does Not Affect Adverse Events While Awaiting Surgery for Ankle Trauma in One System.

INTRODUCTION: Ankle injuries that are not properly cared for can have devastating effects on a patient's health and ability to maintain an active lifestyle. Recommended outpatient surgery may be difficult to obtain for many groups of patients, including those without insurance or minority races. Patients who are of low socioeconomic status also have worse outcomes following trauma. The purpose of this study was to examine whether insurance status impacts the number of adverse events that patients face prior to receiving surgical treatment following an emergency department (ED) visit for an acute ankle injury. METHODS: We conducted a retrospective chart review at two medical centers within the same healthcare system. The sample included 192 patients presenting to the ED with an unstable ankle injury between October 1, 2015- May 1, 2018. We used chi-square and t-test analysis to determine differences in rates of adverse events occurring while awaiting surgery. RESULTS: Few (4%) patients presented as being self-pay. Neither Medicare (χ2 (1) (N = 192) = 2.389, p = .122), Medicaid (χ2 (1), (N = 192) = .084, p = .772), other insurances (χ2 (1) (N = 192) = .567, p = .452), or private insurance (χ2 (1) (N=192) = .000, p = .982) was associated with a difference in rates of adverse events. Likewise, gender (χ2 (1) (N = 192) = .402, p = .526), race (χ2 (3) (N = 192) = 2.504, p = .475), and all other demographic variables failed to show a difference in occurrence of adverse events. Those admitted to the hospital did show a lower rate of adverse events compared to those sent home from the ED (χ2 (1) (N = 192) = 5.452, p = .020). Sampled patients were admitted to the hospital at a high rate (49%). CONCLUSION: The sampled facilities did not have adverse event rates that differed based on insurance status or demographic features. These facilities, with hospital-based subsidy programs and higher than expected admission rates, may manage their vulnerable populations well and may indicate their efforts to eliminate health disparity are effective.

Australian netball injuries in 2016: An overview of insurance data.

OBJECTIVES: The objective of this study is to profile the netball-specific sporting injuries from in a national community-level insurance claim database. DESIGN: An audit of insurance injury claims. METHODS: An electronic dataset containing successful injury insurance claim data from the 2016 netball season was retrospectively coded. Data were de-identified and coded to meet the Orchard Sports Injury Classification System. Descriptive data reported included age, injury date, activity type, anatomical injury location, nature of injury, weather conditions, indoor/outdoor surface, quarter injury occurred, and open text for injury description. RESULTS: The dataset contained 1239 claims that were approved for payment by the insurance company. The overall incidence rate was 2.936 successful injury claims per 1000 participants. The average age of players with claims was 34years. The majority of successful claims came from players aged 22 to 29years (n=328; 27%) and 30-39years (n=279; 23%) age groups. Of the successful claims for injury, most occurred during matches (n=1116; 92%), and were for injuries to the knee (n=509; 42%) and ankle (n=356; 29%) and for sprains/ligament damage (n=687; 57%) or fractures (n=182; 15%). CONCLUSIONS: Netball injuries profiled by an injury insurance dataset of successful claims mostly occurred to the knee and ankle. Sprains and ligament damage were the most common type of injury. This study strengthens the evidence for national injury prevention policies and strategies. Findings from the current study could be used in future to expand into mechanisms of injury, and injury diagnoses.

Is Radiography Necessary for Pediatric Emergency Department Clinicians to Safely Manage Ankle Injuries?

OBJECTIVES: Ankle radiography in the pediatric emergency department exposes a radiosensitive population to harmful ionizing radiation and is costly to health care systems. This study aimed to determine if ankle injuries in children could be managed safely and effectively without radiography. METHODS: This prospective study enrolled 94 patients with ankle injuries between July 14, 2015, and December 16, 2015. Participating clinicians filled out a tick-box questionnaire describing their predicted diagnosis and management. In March 2016, we looked retrospectively at TRAK to determine how these patients were actually managed and compared this with the predictions. RESULTS: Agreement was calculated for the predicted and actual presence of a fracture, with a κ value of 0.433. The intraclass correlation coefficient was calculated to determine interrater reliability between predicted management and actual management, showing an average score of 0.801. Of the 16 patients found to be Low Risk Ankle Rule positive, none were found to have high-risk fractures. CONCLUSIONS: This study found that radiographs are necessary for the management of pediatric ankle injuries. However, there is scope to reduce radiography by implementing the Low Risk Ankle Rule.

Current Trends in the Management of Lateral Ankle Sprain in the United States.

OBJECTIVE: To characterize trends in the acute management (within 30 days) after lateral ankle sprain (LAS) in the United States. DESIGN: Descriptive epidemiology study. PATIENTS: Of note, 825 718 ankle sprain patients were identified; 96.2% were patients with LAS. Seven percent had an associated fracture and were excluded from the remaining analysis. SETTING: Primary and tertiary care settings. INTERVENTIONS: We queried a database of national health insurance records for 2007 to 2011 by ICD-9 codes for patients with LAS while excluding medial and syndesmotic sprains and any LAS with an associated foot or ankle fracture. MAIN OUTCOME MEASURES: The percentage of patients to receive specific diagnostic imaging, orthopedic devices, or physical therapy treatments within 30 days of the LAS diagnosis and the associated costs. RESULTS: Over two-thirds of patients with LAS without an associated fracture received radiographs, 9% received an ankle brace, 8.1% received a walking boot, 6.5% were splinted, and 4.8% were prescribed crutches. Only 6.8% received physical therapy within 30 days of their LAS diagnosis, 94.1% of which performed therapeutic exercise, 52.3% received manual therapy, and 50.2% received modalities. The annual cost associated with physician visits, diagnostic imaging, orthopedic devices, and physical therapy was 152 million USD, 81.5% was from physician evaluations, 7.9% from physical therapy, 7.2% from diagnostic imaging, and 3.4% from orthopedic devices. CONCLUSIONS: Most patients with LAS do not receive supervised rehabilitation. The small proportion of patients with LAS to receive physical therapy get rehabilitation prescribed in accordance with clinical practice guidelines. The majority (>80%) of the LAS financial burden is associated with physician evaluations.

Injuries in Swedish floorball: a cost analysis.

The epidemiology of sport injuries is well documented. However, the costs are rarely discussed. Previous studies have presented such costs in specific sports or localization. No study has investigated the costs related to injuries in elite floorball. Thus, the aim of this study was to estimate cost of injuries in Swedish elite floorball players. During 1 year, 346 floorball players were prospectively followed. All time-loss injures were recorded. The injured players were asked to complete a questionnaire regarding their costs tied to the injury. Mean costs were calculated by multiplying the total resource use with the collected unit costs and dividing these total costs with the number of injuries as well as players. The results showed that the average cost per injury increased with the level of severity and ranged from 332 to 2358 Euros. The mild and moderate overuse injuries were costlier than the corresponding traumatic injuries. However, the severe traumatic injuries were associated with higher costs than overuse injuries. Knee injuries were the costliest. Our results indicate that there are costs to be saved, if floorball injuries can be avoided. They should be of interest to decision makers deciding whether to invest in preventive interventions.

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.

Incidence and Cost of Ankle Sprains in United States Emergency Departments.

BACKGROUND: Ankle sprains represent a common injury in emergency departments, but little is known about common complications, procedures, and charges associated with ankle sprains in emergency departments. HYPOTHESIS: There will be a higher incidence of ankle sprains among younger populations (≤25 years old) and in female patients. Complications and procedures will differ between ankle sprain types. Lateral ankle sprains will have lower health care charges relative to medial and high ankle sprains. STUDY DESIGN: Descriptive epidemiological study. LEVEL OF EVIDENCE: Level 3. METHODS: A cross-sectional study of the 2010 Nationwide Emergency Department Sample was conducted. Outcomes such as charges, complications, and procedures were compared using propensity score matching between lateral and medial as well as lateral and high ankle sprains. RESULTS: The sample contained 225,114 ankle sprains. Female patients sustained more lateral ankle sprains (57%). After propensity score adjustment, lateral sprains incurred greater charges than medial ankle sprains (median [interquartile range], $1008 [$702-$1408] vs $914 [$741-$1108]; P < 0.01). Among complications, pain in the limb (1.92% vs 0.52%, P = 0.03), sprain of the foot (2.96% vs 0.70%, P < 0.01), and abrasion of the hip/leg (1.57% vs 0.35%, P = 0.03) were more common in lateral than medial ankle sprain events. Among procedures, medial ankle sprains were more likely to include diagnostic radiology (97.91% vs 83.62%, P < 0.01) and less likely to include medications than lateral ankle sprains (0.87% vs 2.79%, P < 0.01). Hospitalizations were more common following high ankle sprains than lateral ankle sprains (24 [6.06%] vs 1 [0.25%], P < 0.01). CONCLUSION: Ankle sprain emergency department visits account for significant health care charges in the United States. Age- and sex-related differences persist among the types of ankle sprains. CLINICAL RELEVANCE: The health care charges associated with ankle sprains indicate the need for additional preventive measures. There are age- and sex-related differences in the prevalence of ankle sprains that suggest these demographics may be risk factors for ankle sprains.

Evidence review for the 2016 International Ankle Consortium consensus statement on the prevalence, impact and long-term consequences of lateral ankle sprains.

Lateral ankle sprains (LASs) are the most prevalent musculoskeletal injury in physically active populations. They also have a high prevalence in the general population and pose a substantial healthcare burden. The recurrence rates of LASs are high, leading to a large percentage of patients with LAS developing chronic ankle instability. This chronicity is associated with decreased physical activity levels and quality of life and associates with increasing rates of post-traumatic ankle osteoarthritis, all of which generate financial costs that are larger than many have realised. The literature review that follows expands this paradigm and introduces emerging areas that should be prioritised for continued research, supporting a companion position statement paper that proposes recommendations for using this summary of information, and needs for specific future research.

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.

CT assessment of the prevalence of retinacular injuries associated with hindfoot fractures.

OBJECTIVE: To determine the incidence of injuries to the flexor and peroneal retinacula in hindfoot fractures as demonstrated on ankle computed tomography (CT). MATERIALS AND METHODS: Study patients were identified via review of CT records at a single institution. CT scans were retrospectively reviewed and compared with surgical reports. RESULTS: Hindfoot fractures undergoing CT showed flexor retinacular injuries in 23.7% of cases and peroneal retinacular injuries in 10.2%. The posterior tibial tendon was partly torn in 4.2% of cases, and entrapped between fracture fragments in 16.1%. The peroneal tendon was rarely injured, being entrapped in 1.7% of cases. Pilon, distal tibial shaft, malleolar, talar, and calcaneal fractures were all associated with retinacular injuries. CT findings correlated well with surgical findings; there were no false-positive CT findings, and only 1 false-negative finding, a posterior tibial tendon that was entrapped at surgery, but in a normal position on the CT. CONCLUSIONS: Retinacular injuries are commonly demonstrated on CT in patients with ankle fractures. The contribution of these injuries to fracture outcomes is unknown.

The epidemiology of injury in skateboarding.

The purpose of this report is to review the available literature to provide an epidemiological overview of skateboarding injuries, as well as to suggest possible areas for future research. A literature search was performed with the databases of PubMed, Sport Discus, Google and Google Scholar using the search terms 'skateboard', 'skateboarding', 'injury' and 'injuries', with all articles published in refereed journals in the English language being considered. An ancestry approach was also used. Articles from non-juried journals were also infrequently included to provide anecdotal information on the sport. Comparison of study results was compromised by the diversity of different study populations and variability of injury definitions across studies. The majority of injuries affect young males although conflicting arguments arise over the issues of age and experience in relation to injury severity. Most injuries are acutely suffered, and the most commonly affected body part was the wrist and forearm, with lower leg and ankle injuries also common. The incidence was relatively high but reports on severity differed. Clear conclusions could not be drawn on environmental location and risk factors. Most injuries tend to occur from a loss of balance leading to a fall, in more recent times due to a failed trick. Research on injury prevention is not conclusive although protective equipment and skatepark use are recommended. Further research using more rigorous study designs is required to gain a clearer picture of the incidence and determinants of injury, and to identify risk factors and viable injury countermeasures.

Is surgical fixation for stress-positive unstable ankle fractures cost effective? Results of a multicenter randomized control trial.

OBJECTIVES: A recent multicenter randomized control trial demonstrated similar quality of life at 1 year after open reduction and internal fixation (ORIF) compared with nonoperative treatment for stress-positive unstable isolated lateral malleolar fractures. We sought to determine the cost-effectiveness of ORIF compared with nonoperative management of these isolated lateral malleolar fractures. DESIGN: Cost-utility analysis using decision tree and Markov modeling based on data from a prospective randomized control trial and previously published literature. A single-payer perspective with 1-year and lifetime time horizons was adopted. SETTING: Clinical trial data from 6 Canadian level I trauma hospitals. INTERVENTION: Lateral malleolus ORIF versus nonoperative treatment. MAIN OUTCOME MEASUREMENTS: Incremental cost-effectiveness ratio (ICER). RESULTS: The base case 1-year ICER of the ORIF treatment was $205,090 per quality-adjusted life year gained, favoring nonoperative treatment. For the lifetime time horizon, ORIF becomes the preferred treatment with an ICER of $16,404 per quality-adjusted life year gained. This conclusion is stable provided ORIF lowers the lifetime incidence of ankle arthrosis by >3% compared with nonoperative treatment. Probabilistic sensitivity analysis demonstrated that 33% of model simulations favored ORIF in the 1-year time horizon and 65% of simulations in the lifetime time horizon. CONCLUSIONS: From a single-payer governmental perspective, ORIF does not seem to be cost effective in the 1-year time horizon; however, if operative fixation decreases the lifetime incidence of posttraumatic ankle arthrosis by >3%, then ORIF becomes the economically preferred treatment. LEVEL OF EVIDENCE: Economic Level II. See Instructions for Authors for a complete description of levels of evidence.

Rest easy? Is bed rest really necessary after surgical repair of an ankle fracture?

INTRODUCTION: Bed rest with elevation of the affected limb is commonly prescribed postoperatively following ankle fracture fixation although there is no evidence that this is necessary. AIM: The aim of this prospective, randomised study was to investigate the effects of early mobilisation following surgical fixation of an ankle fracture on wound healing and length of stay (LOS). METHOD: A total of 104 patients underwent primary internal fixation of an ankle fracture at The Alfred hospital, Melbourne between July 2008 and January 2010. INTERVENTION: The strategy included either early mobilisation group (first day post surgery) or control group (bed rest with elevation until day 2 post surgery). OUTCOME MEASURES: Data collected included demographic, injury type and surgical procedure. Outcome data included inpatient LOS, wound condition at 10-14 days, opioid use and re-admission rate. RESULTS: Groups were comparable at baseline. Wound breakdown rate was 2.9% (3 patients in the control group). Median LOS of the early mobilisation group was 55 h compared with 71 h in the control group (p<0.0001). Opioid use for the control group was an average of 90 mg morphine equivalent in the first 24 h post surgery compared with 67 mg morphine equivalent for the early mobilisation group (p=0.32). CONCLUSION: This study indicates that early mobilisation following surgical fixation of an ankle fracture results in a shorter hospital stay without evidence of an increased risk of re-admission or wound complication.

Systematic review of the parachute ankle brace: injury risk reduction and cost effectiveness.

INTRODUCTION: Military parachuting has been shown to result in injuries. This investigation systematically reviewed studies examining the influence of the parachute ankle brace (PAB) on injuries during military parachuting and performed a cost-effectiveness analysis. EVIDENCE ACQUISITION: Parachute ankle brace studies were obtained from seven databases, personal contacts, and other sources. Investigations were reviewed if they contained original, quantitative information on PAB use and injuries during parachuting. Meta-analysis was performed using a general variance-based meta-analysis method that calculated summary risk ratios (SRR) and 95% CIs. EVIDENCE SYNTHESIS: Five studies met the review criteria. Compared with PAB users, PAB non-users had a higher risk of ankle injuries (SRR=2.1, 95% CI=1.8-2.5); ankle sprains (SRR=2.1, 95% CI=1.4-3.1); ankle fractures (SRR=1.8, 95% CI=1.1-2.9); and all parachuting injuries combined (SRR=1.2, 95% CI=1.1-1.4). The PAB had little effect on lower body injuries exclusive of the ankle (SRR [no PAB/PAB]=0.9, 95% CI=0.7-1.2). Cost-effectiveness analysis estimated that, for every dollar expended on the PAB, a savings of about $7 to $9 could be achieved in medical and personnel costs. CONCLUSIONS: The PAB reduces ankle injuries by about half and is a cost effective device that should be worn during military airborne operations to reduce injury risk.

Epidemiology of foot injury in a high-income developing country.

OBJECTIVES: To study the epidemiology of foot injuries and factors predicting their severity in a high-income developing country so as to define prevention priorities. PATIENTS AND METHODS: All patients admitted to Al-Ain Hospital with foot injury between March 2003 and March 2006 were identified from a prospectively collected Trauma Registry. Injuries were scored using foot and ankle severity scale (FASS). Bilateral, multiple or segmental injuries, open fractures or those with FASS score higher than 3 were included in severe foot injury group and compared with simple foot injury group regarding patients' demography, co-morbidities, trauma mechanism and energy, incident location, number of associated injuries, Injury Severity Score (ISS) and hospital stay using a univariate analysis. A logistic regression model was then used to study factors predicting severity of foot injury. RESULTS: 171 patients (156 males) were studied. The average (range) age was 34 (2-75). 95 had right foot injury, 66 had left, and 10 had both. Fall from height was the most common mechanism. 105 (61%) had work-related injuries. 130 (76%) had isolated foot injury. 151 (88%) had 212 foot fractures. 20 (12%) had soft tissue injuries. 70 (41%) had severe injuries while 101 (59%) had simple ones. The multiple logistic model was highly significant (p=0.002). Number of associated injuries (p=0.025) and location of trauma (p=0.044) were significant while the amount of energy (p=0.054) showed a strong trend to predict severity. CONCLUSIONS: Fall from height is the most common mechanism of foot injury in United Arab Emirates. The number of associated injuries, high-energy trauma, and being work related are predictors of foot injury severity. Prevention priorities include counteractions against falling from height and falling heavy objects as occupational hazards.
