UEFA Women's Elite Club Injury Study: a prospective study on 1527 injuries over four consecutive seasons 2018/2019 to 2021/2022 reveals thigh muscle injuries to be most common and ACL injuries most burdensome.

OBJECTIVE: Injuries in women's football (soccer) have scarcely been investigated, and no study has been conducted in the highest competitive level involving club teams from different countries. Our aim was to investigate the time-loss injury epidemiology and characteristics among women's elite football players over four seasons. METHODS: 596 players from 15 elite women's teams in Europe were studied prospectively during the 2018/2019 to 2021/2022 seasons (44 team seasons). Medical staff recorded individual player exposure and time-loss injuries. Injury incidence was calculated as the number of injuries per 1000 playing hours and injury burden as the number of days lost per 1000 hours. RESULTS: 1527 injuries were recorded in 463 players with an injury incidence of 6.7 (95% CI 6.4 to 7.0) injuries per 1000 hours and a nearly fourfold higher incidence during match play compared with training (18.4, 95% CI 16.9 to 19.9 vs 4.8, 95% CI 4.5 to 5.1; rate ratio 3.8, 95% CI 3.5 to 4.2). Thigh muscle injuries (hamstrings 12%, 188/1527, and quadriceps 11%, 171/1527) were the most frequent injury, while anterior cruciate ligament (ACL) injury had the highest burden (38.0 days lost per 1000 hours, IQR 29.2-52.1) with median days lost of 292 (IQR 246-334) days. Concussions constituted 3% (47/1527) of all injuries, with more than half of them (55%, 26/47) due to ball-related impact. CONCLUSION: An elite women's football team can expect approximately 35 time-loss injuries per season. Thigh muscle injury was the most common injury and ACL injury had the highest injury burden.

Thigh compartment syndrome: Outcomes in an urban level 1 trauma center.

INTRODUCTION: Thigh compartment syndrome (TCS) is a rare surgical emergency associated with a high risk of morbidity with mortality rates as high as 47 %. There is sparse literature discussing the management as well as outcomes of these injuries. The purpose of this study is to review a consecutive series of patients presenting to a single urban Level 1 trauma center with TCS to identify injury characteristics, clinical presentation, and outcomes associated with this injury. METHODS: A trauma database was queried for all patients with a diagnosis of TCS at a single level 1 urban trauma center between January 1, 2011 and December 31, 2021. Demographic and injury variables collected included age, sex, BMI, mechanism of injury, and creatine phosphokinase levels (CPK). Hospital quality measures including time from admission to surgery, length of both hospital and ICU stay, complications, and cost of care were collected. Descriptive statistics are reported as median [interquartile range] or N (percent). RESULTS: There were 14 patients identified with a diagnosis of TCS. All were men with an average age 33.5 [23.5 - 38] years and an average BMI of 26 [22.9-28.1]. The most common cause of injury was blunt trauma (71.4 %), and the remaining 28.6 % were gunshot wound injuries. Within the cohort, 6 (42.9 %) patients sustained a femoral shaft fracture, and 4 (28.6 %) patients sustained a vascular injury. The median initial CPK of patients within this cohort was 3405 [1232-5339] and reached a peak of 5271 [3013-13,266]. The median time from admission to diagnosis was 6.8 [0-236.9] hours. The median time from admission to the operating room was 8.2 [0.6-236.9] hours, and the median number of operating room visits was 3 [2 - 6]. Five patients (35.7 %) wounds were closed with split thickness skin grafting. There were 12 (85.7 %) patients who required ICU care. The median ICU length of stay was 7.5 days [4-15]. The median hospital length of stay was 16.5 days [13.25-38.0]. The median total charges for a patient with thigh compartment syndrome was $129,159.00 [$24,768.00 - $587,152.00]. The median direct variable cost for these patients was $86,106.00 For comparison, the median direct variable cost for patients with femur fractures without TCS at this institution was $8,497.28 [$1,903.52-$21,893.13]. No patients required readmission within 60 days. There were no mortalities. CONCLUSION: TCS is a rare and life-threatening injury associated with significant morbidity. Despite rapid diagnosis and fasciotomy, the majority of the patients have prolonged hospital courses, ICU lengths of stay, and significant costs of treatment. Providers can reference the outcomes reported in this study when caring for TCS patients.

Lipoatrofia semicircular en trabajadores de oficinas: una situación que no desaparece tan rápidamente / Semicircular lipoatrophy in public office workers. A situation that does not disappear so quickly

Introducción: La lipoatrofia semicircular (LS) es un trastorno caracterizado por depresiones en forma de banda en la cara anterolateral de los muslos. Objetivos: determinar la prevalencia de los casos de LS en varias instituciones públicas y privadas de la Provincia de Barcelona, España. Material y Métodos: se realizó estudio retrospectivo, en 969 trabajadores de oficinas públicas y privadas, entre 2018 y 2022. A todos los casos se les realizó examen físico completo con mediciones, fotografía y seguimiento de las lesiones. Los resultados fueron analizados mediante el programa Instat Graphpad 3.10 y se aplicó la prueba de Fischer para determinar la significancia estadística. Resultados: se diagnosticaron 96 casos de los cuales 92 eran mujeres. Prevalencia: 9,9%. El promedio de edad fue 49 años (27-64). La mayoría de las lesiones se localizaron en los muslos en forma bilateral. Las lesiones de LS al final del estudio no desaparecieron en el 60% de los casos, mientras que en un 40% si lo hicieron. Conclusiones: Las lesiones de LS toman un tiempo muy variable para revertir, suele ser un proceso lento cuya duración se mide habitualmente en años. Ni el teletrabajo, ni el índice de masa corporal, tuvieron relación estadísticamente significativa en la desaparición de las lesiones. (AU)

Introduction: Semicircular lipoatrophy (LS) is a disorder characterized by band-shaped depressions on the anterolateral aspect of the thighs. Objectives: to determine the prevalence of LS cases in various public and private institutions in the Province of Barcelona, Spain. Material and Methods: a retrospective study was carried out on 969 workers from public and private offices, between 2018 and 2022. All cases underwent a complete physical examination with measurements, photography, and follow-up of injuries. The results were analyzed using the Instat Graphpad 3.10 program and the Fischer test was applied to determine statistical significance. Results: 96 cases were diagnosed, of which 92 were women. Prevalence: 9.9%. The average age was 49 years (27-64). Most of the lesions were located on the thighs bilaterally. LS lesions at the end of the study did not disappear in 60% of cases, while in 40% they did. Conclusions: LS lesions take a highly variable time to reverse, it is usually a slow process whose duration is usually measured in years. Neither teleworking nor the body mass index had a statistically significant relationship in the disappearance of the lesions (AU)

Comparison of eccentric hamstring strength and asymmetry at return-to-sport after hamstring strain injury among those who did and did not re-injure.

OBJECTIVES: The primary aim of this study was to describe eccentric hamstring strength magnitude and asymmetry at the time of return-to-sport (RTS) after an index hamstring strain injury (HSI) and determine if there were differences in strength asymmetry at RTS between those who did and did not go on to re-injure within 1-month and within 3-months of RTS. DESIGN: Cross-sectional study. SETTING: Laboratory-based. PARTICIPANTS: Sixty National Collegiate Athletic Association Division I athletes with index HSI. MAIN OUTCOME MEASURES: Maximum hamstring eccentric strength for each limb, total maximum strength summed across limbs, and between-limb asymmetry at the time of RTS following the index HSI, assessed using the NordBord Hamstring Testing System. RESULTS: Of the 60 index HSIs, 8 (13%), and 11 (18%) re-injuries occurred within 1 and 3-months of RTS, respectively. There were no differences between those who did and did not re-injure in maximum eccentric force of either limb (p-values≥0.52), total force from both limbs (p-values≥0.47), and between limb force asymmetry (p-values≥0.91), regardless if re-injury occurred within 1 or 3-months after RTS. CONCLUSIONS: Eccentric hamstring strength and asymmetry measured at the time of RTS did not differ between those who did and did not re-injure within 3-months of RTS.

Single-stage reconstruction of a traumatic tendocutaneous defect of the Achilles using free composite anterolateral thigh flap with vascularized fascia lata.

Combined tendocutaneous defect of Achilles tendon remains a complex reconstructive challenge whereby both the soft tissue coverage and tendon reconstruction have to be considered to achieve a good functional and aesthetic outcome. A 14-year-old boy who sustained an open right calcaneum fracture (Gustilo-Anderson IIIB) with a transected Achilles tendon and huge skin defect from motorcycle wheel spoke injury was admitted. The Achilles tendon repair site broke down following initial surgical debridement and primary repair, resulting in a sizeable combined tendocutaneous defect. Simultaneous soft tissue coverage and tendon defect reconstruction using composite sensate free anterior lateral thigh (ALT) fasciocutaneous flap with vascularized fascia lata was performed subsequently. The vascularized fascia lata was tubularized to wrap the native proximal stump of Achilles tendon and secured using the modified Krakow suturing technique. The distal end of tubularized fascia lata was, then, secured by drilling across right calcaneum bone, passing the suture transosseously and screwed. He led an uneventful postoperative recovery with satisfactory functional and aesthetic outcomes at one year of follow-up. In conclusion, the present case demonstrates the reliability of this technique and its advantages over other flap choices in reconstruction of a huge combined tendocutaneous defect.

Surgical demographics of acute thigh compartment syndrome.

BACKGROUND: The objective of this study was to identify demographic, injury-related, and treatment-related characteristics of patients who underwent decompressive fasciotomies for acute thigh compartment syndrome. METHODS: A cohort of 38 adult patients with acute thigh compartment syndrome treated with fasciotomy at two tertiary care referral centers over a 10-year time period from January 1, 2006 to June 30, 2015 were retrospectively identified. We searched the electronic medical record for patient-related variables (e.g., age, sex, race, smoking status, diabetes mellitus), injury-related variables (e.g., mechanism of injury, associated fractures, other traumatic injuries), treatment-related variables (e.g., delay to treatment, compartments released, number of debridements, use of split-thickness grafts), and outcomes (e.g., amputation, death, sensory/motor impairments at final follow-up). RESULTS: The mean age of our cohort was 47 years, and 35 patients (92%) were male. There were various mechanisms of injury, but the most common mechanisms were spontaneous hematoma (21%), followed by motor vehicle accidents (16%). Associated leg fractures were present in 15 (39%) patients. Delay between time of injury and fasciotomy was greater than 24 hours in 27 patients (71%), 12 to 24 hours in 6 patients (16%), and less than 6 hours in 3 patients (8%). The most frequently released compartment was the anterior compartment only (68%), followed by both the anterior and posterior compartments (16%) and the posterior compartment only (11%). Six patients (16%) had motor impairment, and 2 patients (5%) had sensory impairment at final follow-up. There were 2 deaths (5%) recorded in the hospital course for this cohort, none of which were directly related to compartment syndrome of the thigh. CONCLUSION: Delays to fasciotomy are frequent in the treatment of acute thigh compartment syndrome. The demographics of acute thigh compartment syndrome demonstrate a strong male predominance. Treating providers should recognize spontaneous hematoma and motor vehicle accidents as the most common causes of acute thigh compartment syndrome.

Injury incidence, severity, and burden in elite youth soccer players - A 3-year prospective study.

OBJECTIVES: This study aimed to investigate age-related injury incidence, severity, and burden over a 3-year period in U14 to U19 elite male soccer players in a German youth academy. DESIGN: Descriptive epidemiology study. METHODS: Time-loss injuries of 166 unique players were prospectively documented and injury incidence, severity, and burden were calculated for each age group, body part, and type of injuries. RESULTS: A total of 562 time-loss injuries were recorded. Across all age groups (U14 to U19), injury incidence was 42.2 per squad season (ranging from 30.5 in the U19 to 67.7 in the U15), severity was 11.0 days lost (ranging from 8.0 in the U15 to 17.0 in the U17), and burden was 464.1 days lost per squad season (ranging from 304.9 in the U19 to 756.7 in the U14). The thigh, knee and ankle were the body parts with the highest injury incidence (9.2; 5.9; 5.9), severity (11.0; 16.0; 13.0), and burden (101.6; 94.9; 76.1). Cruciate ligament injuries had both the highest burden (164.4) and severity (137.0), and muscle injuries the highest incidence (11.0) of all types of injuries. U15 had the highest injury incidence (67.7) of all age groups. U14 and U17 had both the highest injury severity (15.0; 17.0) and burden (756.7; 618.8) of all age groups. Age-related patterns were observed for selected types of injuries such as muscle injuries, tendinopathy, bone-stress injury, and fractures. CONCLUSIONS: Injury incidence, severity, and burden substantially differed descriptively between age groups and clear age-related patterns for selected types of injuries were evident.

Acute compartment syndrome of the thigh in a body builder following open reduction and internal fixation for proximal femur fracture.

Acute compartment syndrome (ACS) of the thigh following femoral fracture has been rarely reported in previous literature. This condition must be diagnosed quickly to prevent the affected limb becoming ischaemic. We document the management of ACS of the thigh in a healthy male patient who suffered a proximal femur fracture following a high-speed road traffic accident. Early identification of characteristic clinical signs allowed for a diagnosis of ACS to be made and then managed with an emergency fasciotomy. The patient is a bodybuilder with an exceptionally large muscle mass. This made ACS more difficult to identify and wound closure a complex process over a period of 13 days. We aimed to highlight the importance of maintaining a high index of suspicion for ACS following traumatic injuries, recognising that ACS in larger patients can be mistaken for an increased analgesia requirement and closing fasciotomies slowly using mass tension sutures.

Acute anterior thigh compartment syndrome in Premiership rugby.

A case study of acute compartment syndrome in the anterior lateral thigh of a professional Rugby Union Flanker with no history of trauma is presented. The report covers all details from initial occurrence; medical history; investigations and surgical treatment; manual stimulus and rehabilitation; return to play; challenges and considerations-resulting in a positive outcome. Resultant observations/recommendations are that investigations should be swift and carefully considered to facilitate surgical intervention via decompressive fasciotomy as required.

Surgical versus conservative management of traumatic proximal adductor longus avulsion injuries: A systematic review.

BACKGROUND: Proximal avulsion injuries of the adductor longus have been managed both conservatively and operatively with good clinical outcomes, but there is no consensus on which option yields the best results. Thus, the present study aimed to review the available literature, comparing the outcomes and the time to return to sports with different management options. MATERIAL AND METHODS: This study was conducted according to the PRISMA statement. The literature search was conducted in September 2020. All the clinical trials investigating the management of traumatic proximal adductor longus avulsion injuries were considered for inclusion. Only studies reporting data from athletes were considered. The outcomes of interest were the time to return to sport and return to preinjury activity level. RESULTS: Data from 46 patients were retrieved. The mean follow-up was 24.6 ± 23.8 months. The study population was represented by male athletes with a mean age of 30.0 ± 4.8. Mean stump retraction was 3.3 ± 0.6 cm in the surgical and 1.7 ± 0.6 in the conservative cohort (P = 0.07). The rate of patients returning to prior activity level was similar in the two groups, but surgically treated patients required a longer time to return to sport (3.9 ± 1.5 months vs. 2.2 ± 1.0 months, P = 0.0001). CONCLUSION: Conservative management for traumatic avulsion of the proximal adductor longus insertion may produce shorter time to return to sport. Both conservative and operative strategies allowed to achieve similar pre-injury activity level. LEVEL OF EVIDENCE: IV, systematic review.

Distal Gracilis Tear in an Equestrian.

ABSTRACT: A 61-yr-old female equestrian presented after 2 wks of left medial thigh pain, which developed suddenly while exiting a car. She denied any history of recent trauma or falls. On examination, she was found to have tenderness at the left distal medial thigh with a palpable region of decreased tissue volume at the gracilis myotendinous junction. Point-of-care ultrasound and magnetic resonance imaging confirmed a high-grade partial thickness tear of the left distal gracilis at the myotendinous junction, as well as pes anserine bursal distention. She received physical therapy and underwent a 1-time ultrasound-guided corticosteroid injection to the left pes anserine bursa. At follow-up, her symptoms had significantly improved, and she had returned to horseback riding after 12 wks. Isolated gracilis myotendinous tear is a rare condition, and this is a unique case with an atypical mechanism of injury as gracilis injuries have only been reported during vigorous exercise-related activities rather than transitional movements. This case illustrates the potential increased risk of distal gracilis injury after repetitive corticosteroid injections (genicular nerve blocks and radiofrequency lesioning) in a patient who was also likely predisposed to gracilis microtrauma due to her equestrian activities. Gracilis injury should be considered in the differential diagnosis of distal medial thigh pain, especially in cases with similar interventional and recreational profiles.

Bilateral Post Traumatic Myositis Ossificans of Adductor Longus in a Young Soccer Player: A Case Report and Literature Review.

ABSTRACT: Myositis ossificans traumatica (MOT) is a self-limiting and self-resolving pathology. In most cases, conservative treatment is chosen as the first step. Surgical treatment is reserved for cases of failure of conservative treatment with persistence of pain and mass. The case presented concerns an 18-year-old soccer player suffering from bilateral adductor longus (AL) MOT results following two different sports injuries. The patient reports the appearance of swelling and palpable mass at the proximal and medial region of the thigh, about 2 cm from the pubic symphysis, along the course of the adductor magnus. The radiological investigation showed the presence of a calcification along the course of the right and left AL muscles. Surgical treatment was considered for the right thigh injury, being symptomatic 1 year after the onset and refractory to other treatments. At 3 months of follow-up, the patient was asymptomatic and completed the rehabilitation program for the recovery of muscle strength and range of motion (ROM). In cases where MOT manifests with resistant pain, ROM restriction and daily activity reduction, surgical excision is the preferred option.

One-Year Clinical and Imaging Follow-up After Exercise-Based Treatment for Acute Complete Adductor Longus Tendon Avulsions in Athletes: A Prospective Case Series.

BACKGROUND: Complete avulsions of the adductor longus tendon are serious injuries, yet we have few data to inform clinical decisions on management. Previous studies are limited by a lack of detailed follow-up. PURPOSE: To describe detailed clinical and imaging measures 1 year after complete proximal adductor longus avulsion injuries in athletes who received exercise-based treatment. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: A total of 16 adult male competitive athletes were included in this study <7 days after an acute adductor longus tendon avulsion injury. All athletes were advised to complete a supervised standardized criterion-based rehabilitation protocol. Standardized clinical examination, a modified Copenhagen Hip and Groin Outcome Score (HAGOS), the Oslo Sports Trauma Research Centre Overuse Injury Questionnaire (OSTRC-O), and detailed magnetic resonance imaging (MRI) assessment were performed after inclusion, on the day of completion of the treatment protocol (return to sport), and at 1-year follow-up after injury. RESULTS: One player was lost to follow-up. Median return-to-sport time was 69 days (interquartile range [IQR], 62-84). One player had an early reinjury and performed an additional rehabilitation period. One-year follow-up was completed a median from 405 days (IQR, 372-540) after injury. The median HAGOS score was 100 for all subscales (IQRs from 85-100 to 100-100), and the median OSTRC-O score was 0 (IQR, 0-0). The median range of motion symmetry was 100% (IQR, 97%-130%) for the bent-knee fall-out test and 102% (IQR, 99%-105%) for the side-lying abduction test. Side-lying eccentric adduction strength symmetry was 92% ± 13% (mean ± SD), and median supine eccentric adduction strength symmetry was 93% (IQR, 89%-105%). MRI results at 1-year follow-up showed that from the original complete discontinuity in all cases, 10 athletes (71%) had partial tendon continuity, and 4 (29%) had complete tendon continuity. CONCLUSION: Nonsurgically treated athletes with a complete acute adductor longus avulsion returned to sport in 2 to 3 months. At the 1-year follow-up after injury, athletes had high self-reported function, no performance limitations, normal adductor strength and range of motion, and signs of partial or full tendon continuity as shown on MRI. This indicates that the primary treatment for athletes with acute adductor longus tendon avulsions should be nonsurgical as the time to return to sport is short, there are good long-term results, and there is no risk of surgical complications.

Muscle activity of cutting manoeuvres and soccer inside passing suggests an increased groin injury risk during these movements.

Cutting manoeuvres and inside passing are thought to increase the risk of sustaining groin injuries. But both movements have received little research attention in this regard. The purpose of this study was to investigate the muscle activity of adductor longus and gracilis as well as hip and knee joint kinematics during [Formula: see text]-cutting and inside passing. Thirteen male soccer players were investigated with 3D-motion capturing and surface electromyography of adductor longus and gracilis while performing the two movements. Hip and knee joint kinematics were calculated with AnyBody Modelling System. Muscle activity of both muscles was significantly higher during the cutting manoeuvre compared to inside passing. Kinematics showed that the highest activity occurred during phases of fast muscle lengthening and eccentric contraction of the adductors which is known to increase the groin injury risk. Of both movements, cutting showed the higher activity and is therefore more likely to cause groin injuries. However, passing might also increase the risk for groin injuries as it is one of the most performed actions in soccer, and therefore most likely causes groin injuries through overuse. Practitioners need to be aware of these risks and should prepare players accordingly through strength and flexibility training.

Tumor de células gigantes del fémur / Tumor of giant cells of the femur

El tumor de células gigantes de hueso es un tumor raro de características benignas con un comportamiento agresivo localmente. Predomina en mujeres y por lo general se presenta en la epífisis y metáfisis de los huesos largos. El propósito de este estudio es presentar el caso de un paciente con una lesión tumoral de rodilla y muslo izquierdos de 2 años de evolución y señalar las características diagnósticas de este tumor al mismo tiempo que se revisan los métodos imagenológicos recientes para su confirmación. Se presenta a un paciente masculino de 19 años de edad, que comenzó con dolor, aumento de volumen de la rodilla y muslo izquierdos, acompañado de impotencia funcional. Se reportaron los hallazgos clínicos, radiográficos e histológicos. Debido a la demora entre el inicio de los síntomas y el diagnóstico se practicó el tratamiento quirúrgico del miembro afectado (amputación). Tras 10 meses de observación no se han presentado recidivas o metástasis. Se envió al Servicio de Oncología para valorar e tratamiento con radioterapia. El tumor de células gigantes del hueso es un tumor raro, de buen pronóstico, pero que puede recidivar y causar metástasis cuando se maligniza. Por la posibilidad de transformación en sarcoma requiere estudio y observación periódica. El tiempo para realizar el diagnóstico es fundamental y debe pensarse en este tumor en caso de lesiones líticas de hueso reportadas por imagenología(AU)

The giant cell tumor of bone is a rare benign tumor with a locally aggressive behavior. It predominates in women and usually occurs in the epiphysis and metaphysis of long bones. To present a patient with a tumor lesion left knee and thigh two years of evolution, also noted the diagnostic characteristics of this tumor while recent imaging methods are reviewed for confirmation. 19-year-old male who began with pain, increased volume of the knee and left thigh, accompanied by functional impotensia. clinical, radiological and histological findings were reported. Because of the delay between the onset of symptoms and diagnosis surgical treatment of the affected limb (amputation) was performed. After ten months of observation there have been no recurrences or metastases. The giant cell tumor of bone is a rare tumor with good prognosis but can recur and metastasize when it becomes malignant. The possibility of transformation in sarcoma requires periodic study and observation. The time for diagnosis is essential and should think of this tumor in case of lytic bone lesions reported by imaging(AU)

Injuries in youth football and the relationship to player maturation: An analysis of time-loss injuries during four seasons in an English elite male football academy.

A better insight into injuries in elite-youth football may inform prevention strategies. The purpose of this prospective cohort study was to investigate the frequency, incidence, and pattern of time-loss injuries in an elite male football academy, exploring injuries in relation to age and maturation status. Across four consecutive playing seasons, playing exposure and injuries to all academy players (U'9 to U'21) were recorded by club medical staff. Maturation status at the time of injury was also calculated for players competing in U'13 to U'16 aged squads. Time-loss injury occurrence and maturation status at time of injury were the main outcome measures. A total of 603 time-loss injuries were recorded, from 190 different players. Playing exposure was 229 317 hours resulting in an overall injury rate of 2.4 p/1000 h, ranging from 0.7 p/1000 h (U'11) to 4.8 p/1000 h (U'21). Most injuries were traumatic in mechanism (73%). The most common injury location was the thigh (23%), and the most common injury type was muscle injury (29%) combining to provide the most common injury diagnosis; thigh muscle injury (17%). In U'13-U'16 players, a higher number of injuries to early-maturing players were observed in U'13-U'14 players, while more injuries to U'15-U'16 players occurred when classed as "on-time" in maturity status. Maturation status did not statistically relate to injury pattern; however, knee bone (not-fracture) injuries peaked in U'13 players while hip/groin muscle injuries peaked in U'15 players.
