Introduction: In accordance with the Polish law, pneumatic weapons are weapons that use compressed gas to set a bullet in motion and generate a discharge energy of more than 17J. In recent years, Poland has seen an increase in crimes committed with pneumatic weapons. The research aim of the present study was to measure the velocity of selected 5.5 mm and 6.35 mm caliber shot and to create a model of a human thigh using a pig femur. Material and methods: This study used Air Arms Hi-Power Xtra FAC cal. 5.5 mm and FX Bobcat Mk II cal. 6.35 mm carbines and Haendler& Natterman's Spitzkugel, Hollow Point and Baracuda cal. 5.5 mm and 6.35 mm lead shot and Excite Apollo cal. 5.5 mm and Black Max Lead-Free cal. 6.35 mm lead-free shot. The velocity of the shot at a distance of 10 m was measured and its kinetic energy was calculated; pig femurs were measured and CT imaging was performed. Results: The 5.5mm caliber shot reached velocities between 253 m/s and 278 m/s, obtaining energies between 27J and 44J. The 6.35 mm cal. shot reached velocities between 242 m/s and 254 m/s and energies between 52J and 59J. Pig femurs had an average weight of 410 g, a length of 239 mm, and a shaft diameter at mid-length of 30.6mm. The thickness of pig femur shaft walls was variable. A ballistic model of the human thigh was created using gelatin available in Poland. Conclusions: 1. The number of registered crimes with pneumatic weapons and the wide access to pneumatic devices with the possibility of design modifications justify the initiation of experimental studies on the assessment of gunshot injuries from pneumatic weapons. 2. The parameters of the shaft of a pig femur obtained from pigs weighing about 115 kg are similar to those of a human adult femur, which makes it possible to create a human thigh model. 3. Of the 5.5 mm cal. shot, the highest impact energies were generated by barracuda type shot, and of the 6.35 mm cal. shot, it was barracuda type and lead-free shot. 4. The thickness of the bony layer of the pig femur shaft is heterogeneous; the posterior wall of the shaft is the thickest, the lateral wall is the thinnest; however, it shows the greatest individual variability.

Introduction: The development of pneumatic shooting has led to the construction of technologically advanced devices with discharge energies similar to those of firearms. The pneumatic weapons ammunition market offers a variety of shot which varies in penetration properties and the extent of gunshot damage. In view of the ease of "tuning" of air rifles, a study was conducted of the inlet damage to the anterior femoral surface after pneumatic gunshots. The paper shows the differences in damage parameters depending on the type of shot. Material and methods: In the study, Air Arms Hi-Power Xtra FAC cal. 5.5 mm and FX Bobcat Mk II cal. 6.35 mm pneumatic carbines were used and lead shot by Haendler&Natterman's Spitzkugel type, Hollow Point and Baracuda cal. 5.5 mm and 6.35 mm, as well as lead-free shot Excite Apollo cal. 5.5 mm and Black Max Lead-Free cal. 6.35 mm. Measurements were taken of the extent of inlet damage to the anterior surface of the femoral shaft with X-ray and CT imaging. Results: HollowPoint shot caused the greatest range of gunshot penetration damage in both bone and periosteum, Apollo lead-free shot caused the least. At the same time, HollowPoint shot showed the greatest susceptibility to ricocheting. Conclusions: 1. The type of shot used influences diversified morphology of the holes and the nature of gunshot damage to the femoral shaft. The differences concern both the gunshot holes and the nature, course and extent of associated fractures. 2. The smallest inlet holes and damage to the periosteum with a regular shape are caused by gunshots with pointed and pointed tip pellets. The greatest extent of bone and periosteum inlet damage was observed in gunshots with Hollow Point type shot due to its predisposition to deformation and fragmentation. 3. Radio-imaging studies are a valuable complement to macroscopic visual assessment providing a useful value for identifying the type of shot used.

A retrospective evaluation of individual thigh muscle volume disparities based on hip fracture types in followed-up patients: an AI-based segmentation approach using UNETR.

Background: Hip fractures are a common and debilitating condition, particularly among older adults. Loss of muscle mass and strength is a common consequence of hip fractures, which further contribute to functional decline and increased disability. Assessing changes in individual thigh muscles volume in follow-up patients can provide valuable insights into the quantitative recovery process and guide rehabilitation interventions. However, accurately measuring anatomical individual thigh muscle volume can be challenging due to various, labor intensive and time-consuming. Materials and Methods: This study aimed to evaluate differences in thigh muscle volume in followed-up hip fracture patients computed tomography (CT) scans using an AI based automatic muscle segmentation model. The study included a total of 18 patients at Gyeongsang National University, who had undergone surgical treatment for a hip fracture. We utilized the automatic segmentation algorithm which we have already developed using UNETR (U-net Transformer) architecture, performance dice score = 0.84, relative absolute volume difference 0.019 ± 0.017%. Results: The results revealed intertrochanteric fractures result in more significant muscle volume loss (females: -97.4 cm3, males: -178.2 cm3) compared to femoral neck fractures (females: -83 cm3, males: -147.2 cm3). Additionally, the study uncovered substantial disparities in the susceptibility to volume loss among specific thigh muscles, including the Vastus lateralis, Adductor longus and brevis, and Gluteus maximus, particularly in cases of intertrochanteric fractures. Conclusions: The use of an automatic muscle segmentation model based on deep learning algorithms enables efficient and accurate analysis of thigh muscle volume differences in followed up hip fracture patients. Our findings emphasize the significant muscle loss tied to sarcopenia, a critical condition among the elderly. Intertrochanteric fractures resulted in greater muscle volume deformities, especially in key muscle groups, across both genders. Notably, while most muscles exhibited volume reduction following hip fractures, the sartorius, vastus and gluteus groups demonstrated more significant disparities in individuals who sustained intertrochanteric fractures. This non-invasive approach provides valuable insights into the extent of muscle atrophy following hip fracture and can inform targeted rehabilitation interventions.

Mixed burn injury to thigh secondary to D-cell lithium battery explosion.

There is an increasing trend globally of fire incidents as a direct consequence of battery failures[1-6], but a dearth of reporting in medical literature regarding injuries associated with primary lithium cell explosions. We present the case of an electrical engineer referred to the burns team as a chemical burn secondary to a D-cell lithium battery explosion. Initial assessment revealed an entry wound on the anteromedial thigh leaking contaminated fluid. Orthogonal X-rays demonstrated the battery casing lodged within the posterior thigh compartment. The wound was managed similar to that of a ballistic injury with staged debridement, washout and delayed primary closure. This is the first reported case of a lithium-thionyl chloride battery explosion causing injury. The case highlights various issues for attending teams, including appropriate first aid for chemical burns, consideration of significant soft tissue trauma deep to seemingly innocuous wounds and safeguarding concerns surrounding domestic explosive devices.

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.

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.

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.

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.

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.
