Epidemiology and Characteristics of Ankle and Foot Injuries in Electric Scooter-Related Accidents.

Background: The use of electric scooters (e-scooters) continues to increase as a simple, inexpensive means of transport, resulting in a sharp increase in the incidence of scooter-related accidents. No study to date has closely examined the injury extent to the lower leg, joints, and extremities from e-scooter-related accidents. Here, we investigated the epidemiology and injury patterns of such accidents, focusing on injuries to the ankle and foot. Methods: Based on data from a single tertiary hospital's database, the demographics of 563 patients with scooter-associated injuries were analyzed retrospectively. Among the patients, 229 patients who were injured by e-scooter riding were further investigated. Based on the data, the general demographics of whole scooter-associated injuries and the injury characteristics and fracture cases of the lower leg, ankle, and foot were analyzed. Results: During the 4-year study period, the number of patients injured by e-scooters increased every year. Lower extremities were the most common injury site (67.2%) among riders, whereas injuries to the head and neck (64.3%) were more common in riders of non-electric scooters. Among the lower leg, ankle, and foot injuries of riders (52 cases), the ankle joint (53.8%) was the most commonly injured site, followed by the foot (40.4%) and lower leg (21.2%). The fracture group scored significantly higher on the Abbreviated Injury Scale than the non-fracture group (p < 0.001). Among the fracture group (20 cases), ankle fractures (9 cases) were most common, including pronation external rotation type 4 injuries (4 cases) and pilon fractures (2 cases). Five patients (25%) had open fractures, and 12 patients (60%) underwent surgical treatment. Conclusions: The ankle and foot are the most common injury sites in e-scooter-related accidents. Given the high frequency and severity of e-scooter-related ankle and foot injuries, we suggest that more attention be paid to preventing these types of injuries with greater public awareness of the dangers of using e-scooters.

Clinical analysis of 1301 children with hand and foot fractures and growth plate injuries.

BACKGROUND: Fractures of hands and feet are common in children, but relevant epidemiological studies are currently lacking. We aim to study the epidemiological characteristics of hand and foot fractures and growth plate injuries in children and provide a theoretical basis for their prevention, diagnosis, and treatment. METHODS: We retrospectively analyzed the data of children with hand and foot fractures who were hospitalized at Shenzhen Children's Hospital between July 2015 and December 2020. Data on demographic characteristics, fracture site, treatment method, etiology of injury, and accompanying injuries were collected. The children were divided into four age groups: infants, preschool children, school children, and adolescents. The fracture sites were classified as first-level (the first-fifth finger/toe, metacarpal, metatarsal, carpal, and tarsal) and second-level (the first-fifth: proximal phalanx, middle phalanx, distal phalanx, metacarpal, and metatarsal) sites. The changing trends in fracture locations and injury causes among children in each age group were analyzed. RESULTS: Overall, 1301 children (1561 fractures; 835 boys and 466 girls) were included. The largest number of fractures occurred in preschool children (n = 549, 42.20%), with the distal phalanx of the third finger being the most common site (n = 73, 15.57%). The number of fractures in adolescents was the lowest (n = 158, 12.14%), and the most common fracture site was the proximal phalanx of the fifth finger (n = 45, 29.61%). Of the 1561 fractures, 1143 occurred in the hands and 418 in the feet. The most and least common first-level fracture sites among hand fractures were the fifth (n = 300, 26.25%) and first (n = 138, 12.07%) fingers, respectively. The most and least common first-level foot fracture locations were the first (n = 83, 19.86%) and fourth (n = 26, 6.22%) toes, respectively. The most common first-level and second level etiologies were life related injuries (n = 1128, 86.70%) and clipping injuries (n = 428, 32.90%), respectively. The incidence of sports injuries gradually increased with age, accounting for the highest proportion in adolescents (26.58%). Hand and foot fractures had many accompanying injuries, with the top three being nail bed injuries (570 cases, 36.52%), growth plate injuries (296 cases, 18.96%), and distal severed fracture (167 cases, 10.70%). Among the 296 growth plate injuries, 246 occurred on the hands and 50 on the feet. CONCLUSIONS: In contrast to previous epidemiological studies on pediatric hand and foot fractures, we mapped the locations of these fractures, including proximal, shaft, distal, and epiphyseal plate injuries. We analyzed the changing trends in fracture sites and injury etiologies with age. Hand and foot fractures have many accompanying injuries that require attention during diagnosis and treatment. Doctors should formulate accident protection measures for children of different ages, strengthen safety education, and reduce the occurrence of accidental injuries.

Acute, isolated fractures of the metatarsal bones: an epidemiologic study.

INTRODUCTION: Although metatarsal fractures are common, the significance of previous epidemiologic studies is limited to specific fracture entities, subpopulations, or heterogeneous fracture aetiologies. The aim of the study was to assess the epidemiology of isolated metatarsal fractures in an adult population at a level-1 trauma centre. MATERIALS AND METHODS: Radiological and clinical databases were searched for a five-year period. Eligible were all patients with acute isolated metatarsal fractures over the age of 18 years with radiographs in two planes available. Stress fractures, injuries affecting Lisfranc joint stability, and concomitant injuries to other regions than the metatarsals were excluded. Data collection included general demographics, mechanism of injury, season of the trauma and fracture details. RESULTS: Out of 3259 patients, 642 patients met the inclusion criteria and were included for the analysis. The patients' mean age was 44.5 ± 18.9 years, 50.6% were female. 83.3% suffered an isolated, 16.7% multiple metatarsal fractures. Single metatarsal fractures occurred predominantly at the fifth metatarsal bone (81.3%), their frequency decreased with increasing age, with a seasonal peak during the summer. Patients suffering multiple metatarsal fractures were significantly older (51.6 ± 21.2 vs. 43.0 ± 18.1 years; p < 0.001) and the injury resulted significantly more often from a high-energy trauma (6.7% vs. 23.4%; p < 0.001). Multiple metatarsal fractures occurred evenly throughout all metatarsals but revealed a focus on female population with no seasonal differences. CONCLUSION: Single metatarsal fractures predominantly occurred at the fifth metatarsal bone and showed a seasonal, gender and age dependency. Multiple metatarsal fractures were homogeneously distributed between the different metatarsals with distinct age-dependent gender differences. LEVEL OF EVIDENCE: Level III.

Incidence and clinical results of tendinous injuries in calcaneus and pilon fractures.

PURPOSE: The aims of this study were: (1) to define the incidence of tendinous injuries in calcaneus and pilon fractures with different fracture severity and (2) to determine the clinical impact of such injuries. STUDY DESIGN AND METHODS: CT-scans of 121 patients with calcaneus and pilon fractures were retrospectively analyzed over a 4-year period. The tendinous injuries were identified and correlated with the type of fracture (location and classification). Clinical analysis was performed using the American Orthopedic Foot and Ankle Society (AOFAS) and SF-36 (Short Form-36 Health Survey) scores. RESULTS: Tendinous injuries were observed in 36% of all CT-scans analyzed, with the most common injury being incarceration (n = 20) and dislocation (n = 24). Calcaneus fractures sanders type 3/4 were 9 times more prone to tendon injury (p < 0.001; OR 8.67; 95% CI 2.49-30.24). Pilon fractures Ruedi-Allgower type 2/3 were 8 times more prone to tendon injury (p = 0.005; OR 7.5; 95% CI 1.72-32.80). No significant differences (p > 0.05) were found in AOFAS and SF-36 scores between patients with/without tendon injuries for fractures with the same severity. CONCLUSION: The incidence of tendon injuries in calcaneus/pilon fractures is high and may be underreported. Calcaneus fractures are prone to peroneal tendon injury. In pilon fractures, it is important to look for tibialis posterior tendon injury, especially entrapment. The presence of tendinous injuries does not affect function and pain for the same type of calcaneus and pilon fractures at the long term. LEVEL OF EVIDENCE: Level 3 retrospective study.

Epidemiological Study of Foot Injuries in the Practice of Sport Climbing.

BACKGROUND: Climbing is a multidisciplinary sport, where the main objective is to reach the highest point of a rock wall or to reach the end of an established route. There are different types of modalities: sport climbing and traditional climbing. The risks and precautions taken with respect to this sport will directly affect the epidemiology of injuries related to its practice. The present study was designed to identify and characterize the most frequent injuries in the feet of climbers and to determine if there is a relationship between the injuries that appear and the time spent practicing the sport. METHODS: A total of 53 people were collected, 32 men and 21 women, corresponding to the climbers of the FEXME (Extremadura Federation of Mountain and Climbing). To determine the diagnoses, exploratory tests, classified according to the variables to be studied, are carried out: inspection variables and questionnaire variables. RESULTS: The average number of years of climbing was seven years, and the average number of hours of training per week was 6.6 h. Some type of alterations were presented in 70% of the respondents, and foot pain was present during climbing in 45% of the participants. The p-value showed a relationship between years of climbing and the occurrence of chronic foot injuries (p = 0.035), however, there is no relationship between the occurrence of injuries and chronological age. CONCLUSION: We can see that the most frequent injuries in the practice of climbing are claw toes, dermal alterations such as bursitis of the first toe and hallux limitus, followed by hallux valgus. Similarly, only a significant relationship was found between the number of years of climbing and the appearance of foot injuries.

[Analysis of 6851 foot and ankle injuries from 2010-2017 in an emergency department]. / Analyse von 6581 Fuß- und Sprunggelenkverletzungen einer Notaufnahme im Zeitraum von 2010­2017.

BACKGROUND: Foot and ankle injuries are among the most common lesions in traumatology, accounting for more than one in ten human fractures. The aim of this study was to investigate the demographic changes of patients with foot and ankle injuries, the temporal occurrence and the development over the years in an emergency department. MATERIAL AND METHODS: Retrospective study of patients treated for foot and ankle injuries in the emergency department from 2010-2017. Patients were identified by ICD codes and demographic changes, temporal occurrence and the development over the years were analyzed. Using quantile-quantile plots, continuous variables were tested for normal distribution and, if applicable, tested for significance using t­tests or non-parametric Mann-Whitney U­tests. RESULTS: A total of 6581 foot and ankle injuries were included in the analysis. The mean age of patients with a foot fracture was 39 ± 17.4 years and with an ankle fracture 47 ± 19.2 years (p < 0.001). Ligamentous ankle injuries occurred particularly in younger patients during the summer months. The age distribution of ankle fractures showed a peak incidence between 30-39 years of age for men and an increased occurrence in women over 50 years. In the age group between 65 and 75 years trimalleolar ankle fractures represented the second most common ankle fracture. Fractures of the foot most commonly affected patients aged 20-29 years, with a second peak incidence in women between the ages of 50 and 59 years. CONCLUSION: Ligamentous injuries of the ankle joint are common injuries in the emergency department and affect mainly younger patients. Ankle fractures showed a bimodal age distribution for women and especially bimalleolar and trimalleolar fractures were more common in women aged 65 years and older. Because of the increased prevalence of foot and ankle fractures in older women, further osteoporosis evaluation should be initiated in this patient population.

Epidemiology and Clinical Outcomes of Foot and Ankle Trauma During the First Wave of the COVID-19 Pandemic in the New York Metropolitan Area.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a novel respiratory virus that has rapidly changed the practice of medicine. The authors sought to evaluate the clinical presentation and clinical outcomes of patients presenting with foot and ankle (F&A) trauma to the emergency department during the first wave of the pandemic. The authors retrospectively studied all patients who presented to an emergency department within their multicenter institution during the first wave of the pandemic in their region from March 1 to June 30, 2020, with F&A trauma. They compared this cohort with a matched control group of patients who presented the prior year. Demographics, perioperative factors, coronavirus disease 2019 (COVID-19) polymerase chain reaction testing/positivity rates, 30-day readmissions, and 30-day mortalities were collected and analyzed. During the pandemic, the authors saw a 62.0% decrease in the total number of patients presenting with F&A trauma. Patients who presented during the pandemic were significantly older and a greater proportion were male. There was a greater proportion of ankle fractures, fewer ankle sprains, and more open fractures presenting during the pandemic. A greater proportion of patients presenting to the emergency department were admitted (18.2% vs 12.5%). The 30-day readmission (n=13 [5.8%] vs n=38 [9.3%]) and mortality (n=4 [1.8%] vs n=3 [0.7%]) rates for admitted patients were similar (P=.114 and P=.232, respectively). The authors found that 9.6% of patients who presented had a positive COVID-19 polymerase chain reaction test result and that these patients had 20% mortality and readmission rates.

Management of foot burns with an emphasis on high-risk groups.

BACKGROUND: Burns injuries are dynamic and evolve over time. Burn injuries to the feet present with seasonal variation, affecting clinical outcomes for certain high-risk groups. Although they affect a very small percentage of the body, burn injuries to the feet can affect mobility, morbidity and rehabilitation, particularly in patients with diabetes. OBJECTIVE: The aim of this article is to provide an understanding of seasonal variation in foot burns for high-risk groups and how to manage them appropriately. This article provides a comprehensive analysis on epidemiology, pathology and management, with the aim of providing guidance for general practitioners (GPs). DISCUSSION: The management of foot burns is multidisciplinary, involving GPs, allied health specialists, nurses, medical and surgical specialties. The epidemiological variations of these injuries have shown differences in clinical outcomes among high-risk groups such as the elderly and people with diabetes. Education and prevention are crucial in reducing the rate of injury in the rising number of patients in high-risk groups.

Retrospective analysis of treatment decisions and clinical outcome of Lisfranc injuries: operative vs. conservative treatment.

PURPOSE: Lisfranc injuries are rare and often pose a challenge for surgeons, particularly in initially missed or neglected cases. The evidence on which subtypes of Lisfranc injuries are suitable for conservative treatment or should undergo surgery is low. The aim of this study was to retrospectively analyze treatment decisions of Lisfranc injuries and the clinical outcome of these patients within the last ten years. METHODS: All patients treated due to a Lisfranc injury in a German level I trauma centre from January 2011 until December 2020 were included in this study. Radiologic images and medical data from the patient files were analyzed concerning the classification of injury, specific radiologic variables, such as the Buehren criteria, patient baseline characteristics, and patient outcome reported with the Foot Function Index (FFI). RESULTS: Ninety-nine patients were included in this study (conservative = 20, operative = 79). The overall clinical outcome assessed by the FFI was good (FFI sum 23.93, SD 24.93); patients that were identified as suitable for conservative treatment did not show inferior functional results. Qualitative radiological factors like the grade of displacement and the trauma mechanism were more strongly associated with the decision for surgical treatment than quantitative radiologic factors such as the distance from the first to the second metatarsal bone. CONCLUSION: If the indication for conservative or operative treatment of Lisfranc injuries is determined correctly, the clinical outcome can be comparable. These decisions should be based on several factors including quantitative and qualitative radiologic criteria, as well as the trauma mechanism.

Worldwide epidemiology of foot and ankle injuries during military training: a systematic review.

INTRODUCTION: Musculoskeletal foot and ankle injuries are commonly experienced by soldiers during military training. We performed a systematic review to assess epidemiological patterns of foot and ankle injuries occurring during military training. METHODS: A review of the literature was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search, done on 14 February 2019, resulted in 1603 reports on PubMed, 565 on Embase and 3 on the Cochrane Library. After reading the remaining full-text articles, we included 91 studies. RESULTS: Among a population of 8 092 281 soldiers from 15 countries, 788 469 (9.74%) foot and ankle injuries were recorded. Among the 49 studies that reported on length of training, there were 36 770/295 040 (18.17%) injuries recorded among women and 248 660/1 501 672 (16.56%) injuries recorded among men over a pooled mean (±SD) training period of 4.51±2.34 months. Ankle injuries were roughly 7 times more common than foot injuries, and acute injuries were roughly 24 times more common than non-acute injuries. Our findings indicated that, during a 3-month training period, soldiers have a 3.14% chance of sustaining a foot and ankle injury. The incidence of foot or ankle injury during military parachutist training was 3.1 injuries per thousand jumps. CONCLUSIONS: Our findings provide an overview of epidemiological patterns of foot and ankle injuries during military training. These data can be used to compare incidence rates of foot and ankle injuries due to acute or non-acute mechanisms during training. Cost-effective methods of preventing acute ankle injuries and non-acute foot injuries are needed to address this problem.

Population-based incidence and epidemiology of 5912 foot fractures.

BACKGROUND: The present study aimed to report a full overview of the incidence and epidemiology of foot fractures. METHOD: Population-based epidemiological cohort study including all foot fractures over 5 years. All patient charts and radiology were manually assessed. RESULTS: A total of 4938 patients sustained 5912 foot fractures during the study period. Patients' mean age at the time of fracture was 36.1 (21.7 SD) years. The overall incidence of foot fractures was 142.3/100,000/year. The hind foot incidence was 13.7/100,000/year, the mid foot incidence 6.5/100,000/year, and the fore foot incidence 123.9/100,000/year. The most common mode of injury was due to low energy trauma (98.7%). CONCLUSION: This study shows an overall incidence of foot fractures to be 142.3/100,000/year. The hind foot incidence is 13.7/100,000/year, the mid foot incidence 6.5/100,000/year, and the fore foot incidence 123.9/100,000/year.

A Single Center Review of the Dangers of Recreational Fires in the Pediatric Population.

The increasing trend of admissions due to recreational fires prompted a 5-year review. The retrospective chart review of pediatric burn injuries from campfires or bonfires treated at a single medical center's burn unit. The study included children within the ages of 0 to 15 admitted or transferred from January 2012 to December 2016 with first, second, and/or third degree burns by bonfires. These patients accrued burns due to active fires as well as postfire ember contact. Two hundred-eighty nine (289) were pediatric admissions out of which 66 (22.8%) were pediatric admissions associated with recreational fires. The mean annual admission for campfire or bonfire burns was 13 ± .98. The mean age was 4 ± 2.47 years. Gender distribution revealed 21 female and 45 male pediatric patients under the age of 15. From the available data, 8 (12%) of these burns occurred at home in the backyard and 16 (24%) at a public camp or park. Injury mechanisms were more commonly a result of direct contact with hot coals and embers (65%). Falls into open flame accounted for 23% (n = 15) of injuries, and flash flames accounted for 12% of injuries (n = 8). The presence of supervision was unknown in 56%; however, lack of supervision was a factor in 14% of our study population. By gaining a better understanding of the type of injury, mechanism of injury, and the demographic of recreational fire burn victims, policy, and awareness campaigns were instituted in an effort to reduce the incidence of recreational fire burns.

The COVID-19 Pandemic: The effect on open lower limb fractures in a London major trauma centre - a plastic surgery perspective.

BACKGROUND: COVID-19 has created huge pressures on healthcare systems. The ongoing provision of major trauma services during this time has proved challenging. We report our experience of managing open lower limb fractures (oLLFs) during the pandemic in a London major trauma centre (MTC). METHODS: This was a prospective study of all open lower limb fractures presenting to our unit over the initial 48 days of UK government lockdown - 24th March till 10th May 2020. Results were compared to the same time period in 2019 retrospectively. Epidemiological data, mechanism, Gustilo-Anderson (G-A) severity grading, time to initial debridement and definitive coverage were analysed. RESULTS: There was a 64% reduction in emergency department (ED) attendances (25,264 vs 9042). There was an 18% reduction in oLLFs (22 vs 18). Approximately three-quarters of injuries were in males across both cohorts (77% vs 78%) and tended to occur in younger patients (median age, 37 vs 35). Road-traffic-accidents (RTAs) were the most common injury mechanism in both 2019 and lockdown, but a rise in jumpers from height was seen in the latter. A similar pattern of G-A severities were seen, however only 3 injuries during lockdown required major soft tissue reconstruction. There was no significant difference in times taken for initial debridement (p = 0.72786) or definitive wound coverage (p = 0.16152). A greater proportion of independent operating was seen during lockdown between orthopaedics and plastic surgery. CONCLUSIONS: Despite government lockdown measures, oLLFs still placed significant burden on our MTC. Notwithstanding significant staffing alterations and theatre pressures, we have been able to ensure these lower limb emergencies remain a surgical priority and have managed to utilise resources appropriately.

Foot Health Assessment and Problem Identification in a Dominican Batey Community: A Descriptive Study.

PURPOSE: Foot problems can adversely impact foot function and quality of life. Foot problems are often overlooked, particularly in populations with limited health care access. Little is known about the foot health of Haitian immigrants who live and work in the bateyes (rural sugarcane villages) of the Dominican Republic. These immigrant workers may experience foot problems that could affect foot function and the ability to work and provide for their families. DESIGN: Cross-sectional, exploratory, descriptive study design. SUBJECTS AND SETTING: A convenience sample of adults was recruited from an ongoing community-based participatory research project evaluating a mobile hypertension screening and treatment clinic program in 11 Dominican batey communities. METHODS: Foot health was assessed using the Foot Problems Checklist, a 24-item survey instrument developed for this study based on a review of the literature and foot clinician expertise. A certified foot care nurse recorded foot health data on the Foot Problems Checklist via visual and physical inspection. RESULTS: Study participants were 25 females and 16 males, aged 18 to 90 years, and all had at least one foot health problem. The most common foot problems were calluses (78%), dry skin (76%), thick nails (59%), jagged nails (29%), long/overgrown nails (17%), and skin fissures (12%). CONCLUSIONS: While the foot problems we observed were not considered serious, they could become progressively debilitating and be prevented with proper self-management guided by appropriate knowledge and skills and available supplies. We recommend the development and testing of foot care self-management interventions deliverable via mobile clinics to increase access and improve foot health outcomes.

Epidemiología y Tratamiento de las fracturas luxaciones del mediopie / Epidemiology and Treatment of fracture-dislocations of the midfoot

OBJETIVO: Análisis de las características demográficas, tipos de tratamiento quirúrgico y resultados de pacientes con lesión de Lisfranc. MATERIAL Y MÉTODOS: Se recogieron los datos de 42 fracturas luxaciones de Lisfranc. Analizamos las características demográficas de nuestra serie y comparamos los resultados entre 25 pacientes intervenidos mediante reducción abierta y fijación interna (RAFI) y 17 mediante artrodesis primaria. RESULTADOS: En relación a las características demográficas, en el 77.8 % de las mujeres el mecanismo de acción fue de baja energía, frente al 45.8% de los hombres con una relación estadísticamente significativa (p = 0.037). No se encontraron diferencias estadísticamente significativas en la escala AOFAS según el mecanismo de acción, la clasificación de la lesión y el tipo de cirugía definitiva. No encontramos una diferencia estadísticamente significativa entre el tipo de tratamiento y las complicaciones con una P de 0.228. No incluimos la retirada de material protocolizada como complicación en el grupo de reducción abierta y fijación interna. CONCLUSIONES: Las lesiones de Lisfranc producidas por mecanismos de baja energía son más frecuentes en mujeres. No se ha podido demostrar la superioridad de un tratamiento respecto a otro en relación a la tasa de complicaciones y los resultados funcionales en la escala AOFAS

OBJECTIVE: Analysis of demographic characteristics, types of surgical treatment and results of patients with Lisfranc lesions. MATERIAL AND METHODS: Based on 42 Lisfranc dislocation, we analyze the demographic characteristics of our series and compare the results between 25 patients treated by open reduction and internal fixation (ORIF) and 17 by primary arthrodesis. RESULTS: In relationto demographic characteristics, in 77.8% of women the mechanism of action was low-energy, compared to 45.8% of men with a statistically significant difference (p 0.037). No statistically significant were found on the AOFAS scale based on mechanism of action, injury classification and type of final surgery. We do not find a statistically significant difference between the type of treatment and complications with a p of 0.228. We do not include the removal of material protocolized as a complication in the ORIF group. CONCLUSIONS: Lisfranc lesions caused by low-energy mechanisms are more common in women. The superiority of one treatment over another in relation to the complication rate and functional results on the AOFAS scale could not be demonstrated

Epidemiology of Foot Injuries Using National Collegiate Athletic Association Data From the 2009-2010 Through 2014-2015 Seasons.

CONTEXT: Researchers analyzing data from the National Collegiate Athletic Association Injury Surveillance Program have not considered the differences in foot injuries across specific sports and between males and females. OBJECTIVE: To describe the epidemiologic differences in rates of overall foot injuries and common injuries among sports and between sexes. DESIGN: Descriptive epidemiology study. SETTING: Online injury-surveillance data from 15 unique sports involving males and females that demonstrated 1967 injuries over 4 821 985 athlete-exposures. PATIENTS OR OTHER PARTICIPANTS: Male and female athletes competing in National Collegiate Athletic Association sports from the 2009-2010 through 2014-2015 seasons. MAIN OUTCOME MEASURE(S): Foot injury rates (per 10 000 athlete-exposures) and the proportion of foot injuries were calculated for each sport. The effect of sex was calculated using Poisson-derived confidence intervals for 8 paired sports. A risk analysis was performed using a 3 × 3 quantitative injury risk-assessment matrix based on both injury rate and mean days of time loss. RESULTS: Foot injury rates differed between sports, with the highest rates in female gymnastics, male and female cross-country, and male and female soccer athletes. Cross-country and track and field had the highest proportions of foot injuries for both female and male sports. The 5 most common injuries were foot/toe contusions, midfoot injuries, plantar fascia injuries, turf toe, and metatarsal fractures. Only track and field athletes demonstrated a significant sex difference in injury rates, with female athletes having the higher rate. The quantitative injury risk-assessment matrix identified the 4 highest-risk injuries, considering both rate and severity, as metatarsal fractures, plantar fascia and midfoot injuries, and foot/toe contusions. CONCLUSIONS: Important differences were present among sports in terms of injury rates, the most common foot injuries, and the risk (combination of frequency and severity) of injury. These differences warrant further study to determine the mechanisms of injury and target intervention efforts.

An Epidemiological Study of Foot and Ankle Motocross Motorcycling Injuries in the United Kingdom.

BACKGROUND: Motocross is a recreational and competitive sport involving motorcycle racing on off-road circuits. Participants have enjoyed their sport worldwide for over 100 years. In the United Kingdom, there are over 200 clubs, with over 900 events annually. Unfortunately, little evidence exists on motocross injuries and their prevention. The aim of this study is to report and to quantify the different foot and ankle injuries observed in motocross. METHODS: Data was collected prospectively between August 2010 to August 2015 at our regional trauma unit, regardless of whether the sport was performed competitively or recreationally. RESULTS: Foot and ankle related injuries were identified in 210 patients (age range 4-78 years), with the majority being male participants (189, 90%). The majority of injuries occurred within the 21- to 30-year-old-age group. Most injuries were sustained around the start of the motocross season, in early spring and the summer months. A total of 76 patients (36%) required operative intervention. The most common injury was ankle fracture (49, 23%), followed by ankle sprain (44, 21%). CONCLUSION: This is the first epidemiological study in the United Kingdom documenting foot and ankle injuries in motocross. The frequency and severity of motocross-related injuries is presented. This may serve to provide recommendations and guidelines in the governing bodies of this sport. The surge in motocross popularity is correlates with an increase in injuries and inevitably the resources required to treat them. LEVEL OF EVIDENCE: Prospective descriptive epidemiological study. Level 1.

Injury Incidence Rates and Profiles in Elite Taekwondo during Competition and Training.

This study aimed to investigate exposure adjusted injury incidence rates and profiles associated with training and competition in an elite taekwondo athlete population. 82 athletes were investigated for injuries over a period of 5 years. Individual fight time exposure for training and competition was recorded. The type and location of the injuries were classified and exposure-adjusted injury incidence rates (IIR) were calculated per 1000 h for training and competition. 66 athletes with a mean age of 19.3±4.2 years and 172 injuries were included in the final data assessment. The exposure adjusted IIR was significantly higher during competition (p<0.001) with a rate ratio of 6.33 (95% CI 4.58-8.69). Ankle and foot region as well as hand and wrist were most affected with significant higher IIR in competition (p<0.001). Joint injuries, fractures, and bruising occurred the most. Fractures occurred mainly to the hand and wrist region. Future investigations should focus on exposure adjusted injury data including analyses of the detailed mechanism leading to especially severe injuries to improve specific injury prevention in competition and promote evolution of protective gear.

Acute Deep Venous Thrombosis and Pulmonary Embolism in Foot and Ankle Trauma in the National Trauma Data Bank: An Update and Reanalysis.

The data regarding rates of deep venous thrombosis and pulmonary embolism after foot and ankle trauma remain sparse. In this study of the National Trauma Data Bank Data set (2007-2009 and 2010-2016), these rates were reexamined and risk factors associated with these complications were assessed. Data quality is improved in the later data set; the incidence of deep venous thrombosis and pulmonary embolism was 0.28% and 0.21%, respectively, in the 2010-2016 data. Prophylaxis, male gender, treatment in a university hospital, open reduction, chronic obstructive pulmonary disease, and hypertension were notable significant risk factors for pulmonary embolism. For deep venous thrombosis, male gender, bleeding disorder, angina, and prophylaxis were risk factors. Careful, individualized assessment of the risk factors associated with deep venous thrombosis and pulmonary embolism is important, and the merits of routine prophylaxis remain in question.
