Context: Long-lever shoulder strength tests may aid clinical decision-making regarding return to sport after a shoulder injury. The Athletic Shoulder Test (AST) was developed to measure force production in 3 positions of shoulder abduction (90°, 135°, and 180°) using force plates. However, handheld dynamometers (HHDs) are more portable, affordable, and may provide valid and reliable results which would increase the clinical utility of long-lever tests. HHDs vary in shape, design, and their capacity to report parameters such as rate of force production and require further investigation. The aim of this study was to examine the intrarater reliability of the Kinvent HHD and assess its validity against Kinvent force plates in the AST. Peak force (in kilograms), torque (in Newton meters), and normalized torque (in Newton meters per kilogram) were reported. Design: Validity and reliability study. Methods: Twenty-seven participants with no history of upper limb injury performed the test in a randomized order using the Kinvent HHD and force plates. Each condition was assessed 3 times, and peak force was recorded. Arm length was measured to calculate peak torque. Normalized peak torque was calculated by dividing torque by bodyweight (in kilograms). Results: The Kinvent HHD is reliable when measuring force (intraclass correlation coefficient [ICC] ≥.80), torque (ICC ≥.84), and normalized torque (ICC ≥.64) during the AST. The Kinvent HHD is also valid when compared with the Kinvent force plates for force (ICC ≥.79; r ≥.82), torque (ICC ≥.82; r ≥.76), and normalized torque (ICC ≥.71; r ≥.61). There were no statistically significant differences across the 3 trials on analyses of variance (P >.05). Conclusions: The Kinvent HHD is a reliable tool when used to measure force, torque, and normalized torque in the AST. Furthermore, given the lack of significant difference between trials, clinicians can use one test to accurately report relative peak force/torque/normalized torque rather than average 3 separate trials. Finally, the Kinvent HHD is valid when compared with Kinvent force plates. [ABSTRACT FROM AUTHOR]

Purpose: Contraindications to replantation include severe medical or psychiatric comorbidities. Recently, authors have suggested that due to the improving therapeutic options for patients with psychiatric decompensation, this should no longer be listed as a contraindication to replantation. Despite this, authors continue to list severe psychiatric comorbidities as a contraindication to replantation. This case series and review of the literature discusses this complex topic and provides recommendations regarding the management of patients following upper extremity self-inflicted amputations. Methods: The authors present two cases of self-inflicted upper extremity amputations. The cases depict the acute management and the outcomes of these patients. The authors also reviewed the literature to present the available literature on this topic. Results: The first case is a 64-year-old male who deliberately amputated his left hand with a table saw while suffering postictal psychosis. He underwent replantation. The patient was co-managed by the surgical and psychiatric team postoperatively. The patient expressed gratitude for his replantation after being treated for his psychoneurological condition. The second case is that of a 25-year-old male who deliberately amputated his left forearm using a Samurai sword. The patient's limb was successfully replanted. In the post-anesthesia care unit, the patient experienced extreme agitation, and during this event, he reinjured the left forearm. He was again taken urgently to the operating room to revise the replantation. Once psychiatrically stabilized, the patient was thankful for the care he received. Conclusion: The management of upper extremity self-inflicted amputations is controversial and difficult to establish as this presentation is rare. We present two cases which illustrate some of the nuances in the care of these patients. Our review suggests that psychiatric diagnosis be viewed as a comorbidity and not a contraindication to replantation. Thus, an informed consent discussion should be performed with the patients and, as needed, a member of the psychiatric team in order to decide whether to replant or not. [ABSTRACT FROM AUTHOR]

Background The disabilities of arm, shoulder, and hand (DASH) questionnaire addresses the patient's disabilities and symptoms to evaluate the extent and the impact of injuries in the patient's daily-life activities. This study aims to develop a valid and reliable adaptation of DASH into the Kurdish language and culture (DASH-KU). Methods American Association of Orthopedic Surgeons Outcomes Committee guideline was used for the cross-cultural adaptation of DASH to the Kurdish version. This study was conducted at the Shahid Saifaddin consultation clinic in Sulaymaniyah, Iraq between April and October 2022. A total of 300 participants, who were included in the study using an available sampling method, completed the self-report DASH-KU questionnaire during two consecutive assessments with a 24-hour interval. Results The DASH-KU questionnaire demonstrated excellent internal consistency (Cronbach's α = 0.99) and test–retest reliability (intraclass correlation = 0.99). A strong correlation between DASH-KU scores and the patient-rated wrist/hand evaluation tool (r = 0.792) supported its construct validity. Bland–Altman plots showed good agreement between assessments with no floor (3%) or ceiling (0%) effects. Factor analysis found the scale had high adequacy (0.700) and significant sphericity (p < 0.001). The major factor explained 40% of variance with an eigenvalue of 13.14. Additionally, a five-item model explained 81.23% of DASH-KU variance, though responsiveness was suboptimal, possibly due to the short 24-hour interval between measurements. Conclusion Our results demonstrate that DASH-KU has excellent reliability and validity in identifying upper limb injuries, and the psychometric properties of DASH-KU were similar to its original version.

Background: Stress injuries are often missed secondary to their insidious onset, milder symptoms, and subtle or initially absent findings when imaged. Main Body: This review aims to provide strategies for evaluating and treating upper extremity stress fractures. This article outlines the classic presentation of each fracture, the ages during which these injuries often occur, the relevant anatomy and biomechanics, and the mechanism of each injury. Diagnostic imaging and management principles are also discussed, including the use of conservative versus surgical management techniques. Short Conclusion: Upper extremity stress fractures are often mild injuries that resolve with conservative management but can lead to more serious consequences if ignored. Given their increasing incidence, familiarity with diagnosis and management of these injuries is becoming increasingly pertinent. Key Points: Stress injuries are often missed secondary to their insidious onset, milder symptoms, and subtle or initially absent findings when imaged. This review aims to provide strategies for evaluating and treating upper extremity stress fractures. [ABSTRACT FROM AUTHOR]

Introduction Musculoskeletal injuries (MSIs) pose a significant problem for active duty service members (ADSMs). MSIs may compromise readiness and are one of the main reasons for separation from the Navy and long-term disability. Implementation of optimal treatment strategies rests on understanding the characteristics of MSI complaints in a given population. This study reports on the frequency and nature of MSI complaints of ADSMs seeking care at a military treatment facility (MTF). Materials and Methods As part of a larger quasi-experimental study, data on MSIs from ADSMs reporting to an MTF were collected. Subjects completed a baseline questionnaire during an initial evaluation, including the self-reported MSIs for which participants were seeking care, time since onset, and other MSI comorbidities. Results Of the 289 respondents, 118 (41%) were female and 172 (59%) were male. The mean age was 33 years (SD = 8). The most frequently reported injury was low-back pain (n  = 79, 27%), followed by knee pain (n  = 60, 21%) and shoulder pain (n  = 55, 19%). Thirty-four (12%) respondents reported injuries to the ankle or foot. The remaining respondents (21%) reported injuries to the neck, mid-back, arm or hand, hip, or other. Sixty-five (22%) reported an acute/subacute injury of less than 3 months, whereas 224 (78%) reported chronic injury >3 months. Furthermore, MSI comorbidities were reported by 233 (80%) of respondents with 128 of those reporting more than one. Conclusions Back and knee injuries were most prevalent in ADSMs reporting an MSI at a Navy shore-based MTF. Shoulder injuries were also common. Of interest, 80% of ADSMs reported at least one MSI comorbidity and 80% reported chronic injury in this study. These rates are higher than those found in a previous study of ADSMs deployed on a carrier. This is notable because chronicity and multiple MSIs are obstacles to readiness. Our findings suggest that ADSMs reporting to shore-based facilities may be at higher risk for disability than their deployed counterparts. This information is important to the development of targeted care to improve readiness in this population. [ABSTRACT FROM AUTHOR]

Background: Upper extremity injuries (UEIs) are common in the emergency departments, yet they are under-reported in developing countries. This study examined the frequency, injury characteristics, and treatment approaches of upper extremity fractures (UEFs) among hospitalized trauma patients in a nationally representative population. Methods: We conducted a retrospective, observational study including all the hospitalized patients with UEFs in the only level 1 trauma center in Qatar between July 2015 and August 2020. Comparative analyses were performed according to injury mechanisms, severity, and management approach. Results: A total of 2,023 patients sustained UEIs with an average age of 34.4 ± 12.9 years, and 92% were males. Motor vehicle crashes (MVCs; 42.3%) were the primary cause of shoulder girdle injuries in 48.3% of cases. Fractures of the radius, ulna, and hands occurred in 30.8, 16.5 and 14.5%, respectively. Young adults were more involved in MVCs and motorcycle crashes (MCCs), while pedestrians who were typically older had a higher rate of humerus fractures. Patients with MCCs had a higher rate of clavicle and ulna fractures. Pedestrians were at risk of serious injuries, with a higher mean injury severity score and lower Glasgow Coma Scale. Conclusion: Most UEFs patients were young males and mainly affected by MVCs. Shoulder girdle, particularly clavicle and scapula/glenoid fractures, emerged as common injury sites. The study highlighted the potential risk of pedestrian injuries, as reflected in higher injury severity, concomitant injuries, and higher mortality. Future studies are needed to optimize preventive measures by incorporating insights into specific injury mechanisms and patterns of UEIs. [ABSTRACT FROM AUTHOR]

To explore barriers and facilitators to community reintegration experienced by people following traumatic upper limb amputation (ULA). An exploratory qualitative study was conducted with ten adults with major ULA due to trauma. Data from individual, semi-structured interviews was analysed using Braun and Clarke's reflexive thematic analysis. Underlying and influencing community reintegration for participants, was a process of adjustment to the impacts of amputation on everyday function and re-establishing their identity. Participants felt social networks and peer support facilitated the return to social and community activities, as did drawing on personal attributes such as positivity, resilience and self-belief. Prosthetic devices were facilitative for community reintegration by minimising visible differences and unwanted attention through restored cosmesis and in the performance of functional tasks to fulfil social norms and meaningful roles despite issues with comfort and function. Despite the adaptation and evolution of abilities, perspectives and identities, the functional impact of ULA on everyday community activities was an ongoing challenge for all participants. ULA has a significant and lifelong impact on an individual's ability to complete tasks and fulfil meaningful roles in the community. Recommendations based on the study's findings will inform clinicians to support community reintegration for people following traumatic ULA. Rehabilitative environments and interventions that promote self-efficacy, positivity, problem-solving skills and resilience may support adjustment and community reintegration following upper limb amputation. Facilitating appropriate peer support and the strengthening of existing social supports may assist social and community reintegration. The facilitative effects of prosthetics on community participation and reintegration may be enhanced through client-centred, goal-directed and timely prosthetic provision and training. Ongoing barriers and challenges with community participation may indicate the need for ongoing therapeutic intervention and support. [ABSTRACT FROM AUTHOR]

Shoulder and elbow pain are the common complaints associated with throwing injuries in baseball players. Prospective studies evaluating the effectiveness of stretching in increasing posterior shoulder flexibility or strengthening the external rotator muscles as preventive strategies for throwing injuries in baseball players have been published. However, there are limited reviews highlighting the role of preventive interventions for throwing injuries in baseball players. Therefore, this scoping review aimed to summarize the existing literature on preventive interventions for throwing injuries in baseball players. We searched the Cochrane Central Register of Controlled Trials, MEDLINE, and Scopus databases on 3 March 2023. Two independent reviewers screened the studies based on the eligibility criteria. We extracted existing literature on preventive interventions and effectiveness for throwing injuries in baseball players, and participants' characteristics and results were extracted from the studies. This scoping review was performed in accordance with the Extended Preferred Reporting Items for Systematic Reviews and Meta-Analyses Statement for Scoping Reviews. The initial database search yielded 1170 articles, four of which met the eligibility criteria. Of the included studies, two were randomized controlled trials, and the remaining two were prospective cohort studies. Eligible studies targeted youth-to high school-level players and focused on preventive programs for throwing injuries that manifest in the upper extremities of baseball players. The outcome measure most commonly used to quantify the effectiveness of prevention programs was the incidence of shoulder and elbow injuries, although the definitions vary among studies. The prevention program included sleeper stretching, shoulder external rotation strengthening exercises, and comprehensive prevention programs (focusing on improving the elbow, shoulder, and hip range of motion; rotator cuff and periscapular muscle strength; posture; and lower extremity balance). Each prevention program was reported to have the potential to reduce the incidence of throwing injuries in baseball players, and two studies suggested that high compliance with the program led to a lower injury risk. This scoping review confirmed the presence of studies that examined preventive interventions for throwing injuries in baseball players. Preventive interventions that may reduce throwing injuries in baseball players include sleeper stretching, shoulder external rotation strengthening exercises, and comprehensive prevention programs. However, the characteristics of participants (eg, age, sports level, and position) and the definition of injury varied among previous studies. Injury profiles and prevention strategies may differ according to age, sport level, and position of players, and more studies are needed to prove this issue. [ABSTRACT FROM AUTHOR]

Summary: This 5-year longitudinal study investigated the relationship between depressive symptoms and fracture risk in a large Japanese cohort. Depressive symptoms were a significant risk factor for hip fractures in women. Purpose: A relationship between depressive symptoms and fractures has not been clearly demonstrated. We aimed to investigate the relationship between depressive symptoms and 5-year fracture risk in the Japan Public Health Center-based Prospective Study for the Next Generation. Methods: From 2011 to 2016, 114,092 participants were enrolled, and a follow-up survey was conducted 5 years later. We analyzed 30,552 men and 38,063 women aged 40–74 years who had no past fractures at baseline. Presence of depressive symptoms was defined as a modified 11-item Center for Epidemiological Studies Depression Scale score of 8 or higher, a history of depression, or use of antidepressants. Subjects were asked to report vertebral, upper limb, and/or hip fractures, except for traffic or work accidents, that occurred during the follow-up period. The adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for fracture were analyzed via logistic regression analysis to evaluate the relationship between depressive symptoms and fracture. Results: Women with depressive symptoms demonstrated a high AOR for hip fractures (AOR: 2.78, 95% CI: 1.30 – 5.92); this result was consistent in post menopause women. In men, this association was not found for any age group or any type of fracture. Conclusions: Depressive symptoms in women may increase the risk of hip fractures. Further studies are required to explore this relationship in more detail. [ABSTRACT FROM AUTHOR]

Objectives: Combat sports continue to be a popular form of recreation within the United States. With this continually increasing popularity and participation comes an increase in associated injuries as well. Despite this, there remains a paucity of studies characterizing injury patterns, types, and anatomic distributions of injuries sustained during participation in combat sports, thus necessitating further investigation. The goal of this study is to provide an updated description of injuries within combat sports, specifically to the upper extremity and presenting to US emergency departments (EDs). It is our hope that this information may be utilized by participants and trainers to help develop preventative strategies, as well as by health care professionals to diagnose patients and provide the appropriate treatment more readily and accurately. Methods: A retrospective analysis was performed utilizing data from the United States Consumer Product Safety Commission's (CPSC) National Electronic Injury Surveillance System (NEISS) between 2003 and 2022. Data were limited to product codes 1200 (unclassified sports or recreational activity), 1207 (boxing), 1270 (wrestling), and 3257 (martial arts). The year designation variable was added to each year's remaining dataset, and all years were concatenated into a single compiled dataset containing 84,812 observations. Beginning in 2019, the NEISS database updated their gender designations to include sexes which were unidentified or non-binary. Designations of unidentified or nonbinary genders were removed from the dataset, reducing the sample size to 84,807 observations. Data were then filtered to include only injuries of the upper extremity, reducing sample size to 29,364. Anatomic regions of interest included shoulder, upper arm, elbow, forearm, wrist, hand, and fingers. Narratives were reviewed to remove unclassified injuries that did not describe a combat sport of any type, injuries where the reference was to a different primary cause, or terminology overlap. For example, boxing injuries occurring from punching bag arcade games were excluded. Finally, several diagnoses were excluded, such as contusion, crushing injuries, dermatitis, puncture wounds, hematomas, hemorrhages, and other/not stated. Diagnoses of interest included dislocations, fractures, and strains/sprains. The final sample size was 12,642. Injury rates for specific injury types and upper extremity subregions were described as percentages of total injuries, both within each sport category and across all sports. Injury rates were also assessed on a year-by-year basis, and year-to-year variation within and between sports was assessed using chi-square tests. Results: Of the 12,642 upper extremity injuries for which patients presented to US EDs between the years 2003 and 2022, nearly half were sustained from wrestling (6230, 49.3%) whereas the remaining half were more evenly distributed between boxing (3318, 26.2%) and martial arts (3094, 24.5%). There was a significant effect of time on injury distributions by sport (chi-square test: X2 =80.89, P < 0.001). Even when accounting for the years during COVID-19, significant differences between sports and over time were still detected. When assessing anatomic regions injured by sport, wrestling unsurprisingly accounted for most shoulder (59.5%), upper arm (67.7%), elbow (75.3%), forearm (57.6%), and finger (50.3%) injuries given the amount of overall wrestling injuries compared to boxing and martial arts. Boxing, however, accounted for most hand (64.1%) and wrist (37.7%) injuries, despite fewer overall injuries compared to wrestling. The most frequently injured regions within boxing, wrestling, and martial arts were the hand (40.1%), shoulder, (33.8%), and shoulder (28%), respectively. Regarding injury types, wrestling accounted for the highest percentage of each type, including dislocations (55.7%), fractures (46.9), and strains/sprains (50%). Remaining frequencies for dislocations, fractures, and strains/sprains were roughly equal in distributions for boxing and martial arts. Strains/sprains were much more common than dislocations in each sport as well, with a ~4:1 ratio in boxing, and a ~3:1 ratio in wrestling and in martial arts. The most common specific injuries (anatomic region + injury type) sustained across all sports were shoulder strain/sprain (14.7%), followed by hand fractures (13.1%), wrist strain/sprain (9.5%), finger fractures (8.7%), forearm fractures (7.2%), shoulder dislocation (7.1%), finger strain/sprain (6.4%), shoulder fractures (6.2%), wrist fractures (5.4%), and elbow strain/sprain (5.0%). Wrestling accounted for most of these injuries; however, boxing accounted for the majority of hand fractures and dislocations, as well as strains/sprains of the wrist and upper arm. Conclusions: This study demonstrates significant variability in pattern and location of injuries sustained from wrestling, boxing, and martial arts. By providing updated insight regarding the temporal trends and injury patterns to the upper extremity in boxing, wrestling, and martial arts, this study may assist in the efforts to continue advancing safety measures in a group of sports that continues to gain interest in the United States.

Background: Female sex is a significant determinant of anterior cruciate ligament (ACL) injury. It is not understood if sex is a key determinant of other sports-related injuries. Objective: The aim of this systematic review was to identify where differences in injury profiles are most apparent between the sexes in all sports across the six-tiered participant classification framework. Methods: This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and the 'implementing PRISMA in Exercise, Rehabilitation, Sport medicine and SporTs science'(PERSiST) guidance. The databases PubMed, CINAHL, Web of Science, SPORTDiscus, Medline, Scopus, Cochrane Library and EBSCO were searched from database inception to 24 April 2023. Longitudinal, prospective and retrospective cohort studies and cross-sectional and descriptive epidemiology studies that used standard injury data collection were included. Studies were excluded if injuries were not medically diagnosed and if injuries were not reported and/or analysed by sex. Two reviewers independently extracted data and assessed study quality using the Downs and Black checklist. Results: Overall, 180 studies were included (8 tier-5, 40 tier-4, 98 tier-3, 30 tier-2, 5 tier-1 studies; one study included data in two tiers). Of those, 174 studies were of moderate quality and six studies were of limited quality. In sex-comparable sports, there was moderate evidence that female athletes had greater risk of knee injury (relative risk (RR) 2.7; 95% CI 1.4–5.5), foot/ankle injuries (RR 1.25; 95% CI 1.17–1.34), bone stress injury (RR 3.4; 95% CI 2.1–5.4) and concussion (RR 8.46; 95% CI 1.04–68.77) than male athletes. Male athletes were at increased risk of hip/groin injuries (RR 2.26; 95% CI 1.31–3.88) and hamstring injuries (RR 2.4; 95% CI 1.8–3.2) compared with females, particularly in dynamic sports. Male athletes were 1.8 (1.37–2.7) to 2.8 (2.45–3.24) times more likely to sustain acute fractures than female athletes, with the highest risk in competition. Discussion: Most studies in all cohorts were of moderate quality (mean/range of scores tier-5: 17 ± 2.2 [14–20], tier-4: 16.9 ± 1.9 [11–21], tier-3: 16.9 ± 1.5 [11–20], tier-2: 16.3 ± 2.2 [11–20], tier-1 studies: 15.6 ± 1.3 [14–17] out of 28 on the Downs and Black checklist), with only six studies of limited quality. Female athletes' propensity for bone stress injuries highlights opportunities to reinforce development of optimal bone health during adolescence and to outline the effects of energy availability. Earlier strength development and exposure to neuromuscular training programmes and modification of skill development in female athletes may be effective strategies for reducing lower limb injury risk. Key components of neuromuscular training programmes could be beneficial for reducing hip/groin and hamstring injury risk in male athletes. There may be a need for sex-specific prevention and return-to-sport protocols for sports-related concussion in female athletes. Conclusions: Female sex was a key determinant of sports-related injuries beyond ACL injury including foot/ankle injury, bone stress injury and sports-related concussion. Male sex was a key determinant of hip/groin, hamstring injury and upper limb injury. Trial Registry: PROSPERO registration number: CRD42017058806 (last updated on 7th June 2023).

Golf is one of the most participated sports played worldwide. However, how injury distributions change between different golf populations is unknown, and associated injury risk factors are unclear. Therefore, this review aimed to describe the common musculoskeletal injuries in different golf populations and identify their associated risk factors. A systematic search was performed to identify eligible articles through PubMed, SPORTDiscus, EMBASE, and Scopus up until September 4, 2023. Of the 4643 studies identified, 58 satisfied the inclusion criteria. Data from 10,437 subjects were extracted, with the most common area of injury to all golf populations being the lower back. Different injury distributions were found between populations with elite male golfers (n = 1924 injuries, 62% of all injuries) and recreational male golfers (n = 442 injuries, 45% of all injuries) reporting the trunk as the most injured region, whereas upper-extremity injuries were the most prevalent injury in elite female golfers (n = 890 injuries, 42% of all injuries) and recreational female golfers (n = 178 injuries, 47% of all injuries). Range-of-motion deficits at the hip and spine were identified as risk factors for elite golfers, whereas measures of lower-limb and trunk strength endurance were identified as risk factors for recreational golfers, suggesting areas of focus for golf practitioners. However, there is a paucity of robust studies evaluating the epidemiology of musculoskeletal injuries in all golf populations, and because of the variety of methods and measures used, detailed comparisons and definitive recommendations were difficult to make. Nonetheless, this review provides an overview of the common golf injuries and possible risk factors, which can aid partitioners in developing strategies for injury prevention for all golfing demographics.

Background: Pickleball is one of the fastest-growing sports in the United States, with more than an 11-fold increase in injuries from 2010 to 2019. Purpose: To (1) determine the prevalence and demographic variables associated with pickleball-related fractures among patients evaluated at emergency departments in the United States between 2002 and 2022 and (2) identify variables influencing patient disposition status. Study Design: Descriptive epidemiology study. Methods: The US Consumer Product Safety and Commission's publicly available database, the National Electronic Injury Surveillance System (NEISS), was used in this study. Analyses consisted of descriptive statistics for fracture prevalence and demographic variables as well as univariate analysis for disposition status (discharged home vs hospital admission). Results: A total of 397 pickleball-related fractures were recorded between 2002 and 2022, which indicated a 90-fold increase in our study period. Based on weighted national average of NEISS sampling, this equated to approximately 5400 fractures annually. Players who sustained pickleball fractures were primarily aged >60 years (n = 344 [87%]; P <.001) and female (n = 273 [69%]; P <.001). Most fractures involved the upper extremity (n = 262 [66%]; P <.001), with the most common ones involving the radius (n = 79 [30%]), humerus (n = 22 [8%]), and ulna (n = 8 [3%]). Fractures were due most commonly to falls (n = 365 [92%]; P <.001) and occurred in the winter months (n = 142 [36%]; P <.001). There was a significant difference in disposition status, with most patients discharged (n = 320 [81%] vs n = 77 [19%] for hospital admission; P <.001). Univariate analysis revealed that age >60 years, male sex, and fractures to the trunk and lower extremity all led to significantly increased odds of being admitted (odds ratios: 2.27, 2.31, 2.89, and 13.8, respectively). Conclusion: Between 2002 and 2022, there was a 90-fold increase in pickleball-related fractures. Most fractures were of the upper extremity after a fall in women aged >60 years. Despite female fracture predominance, men were 2.3 times more likely to be admitted after sustaining a fracture. [ABSTRACT FROM AUTHOR]

Purpose: Although the term "major fracture" is commonly used in the management of trauma patients, it is defined insufficiently to date. The polytrauma section of ESTES is trying to develop a more standardized use and a definition of the term. In this process, a standardized literature search was undertaken. We test the hypothesis that the understanding of "major fractures" has changed and is modified by a better understanding of patient physiology. Methods: A systematic literature search of the Medline and EMBASE databases was conducted in March 2022. Original studies that investigated surgical treatment strategies in polytraumatized patients with fractures were included: This included timing, sequence and type of operative treatment. A qualitative synthesis regarding the prevalence of anatomic regions of interest and core factors determining decision-making was performed. Data were stratified by decades. Results: 4278 articles were identified. Of these, 74 were included for qualitative evaluation: 50 articles focused on one anatomic region, 24 investigated the relevance of multiple anatomic regions. Femur fractures were investigated most frequently (62) followed by pelvic (22), spinal (15) and tibial (15) fractures. Only femur (40), pelvic (5) and spinal (5) fractures were investigated in articles with one anatomic region of interest. Before 2010, most articles focused on long bone injuries. After 2010, fractures of pelvis and spine were cited more frequently. Additional determining factors for decision-making were covered in 67 studies. These included chest injuries (42), TBI (26), hemorrhagic shock (25) and other injury-specific factors (23). Articles before 2000 almost exclusively focused on chest injury and TBI, while shock and injury-specific factors (e.g., soft tissues, spinal cord injury, and abdominal trauma) became more relevant after 2000. Conclusion: Over time, the way "major fractures" influenced surgical treatment strategies has changed notably. While femur fractures have long been the only focus, fixation of pelvic and spinal fractures have become more important over the last decade. In addition to the fracture location, associated conditions and injuries (chest trauma and head injuries) influence surgical decision-making as well. Hemodynamic stability and injury-specific factors (soft tissue injuries) have increased in importance over time. [ABSTRACT FROM AUTHOR]

BACKGROUND: Although ambient temperature has been linked with injury incidence, there have been few nationwide studies to quantify the temperature-related risk and burden of cause-specific injury hospitalizations. Additionally, the impact of human-induced climate change to injury burden remains unknown. OBJECTIVES: Our objectives are to examine the associations between ambient temperature and injury hospitalizations from various causes and to quantify the contribution of human-induced warming to the heat-related burden. METHODS: We collected injury hospitalization data from a nationwide hospital-based registry in China during 2000–2019. Using a time-stratified case-crossover design, we investigated the associations between daily mean temperature (°C) and cause-specific injury hospitalizations. We also quantified the burden of heat-related injuries under the scenarios with and without anthropogenic forcing, using the Detection and Attribution Model Intercomparison Project to assess the contribution of human-induced warming. RESULTS: Our study included a total of 988,087 patients with hospitalization records for injuries. Overall, compared to the temperature at minimum risk of hospitalization (-12:1°C), the relative risk of hospitalization at extreme hot temperature (30.8°C, 97.5th percentile) was 1.18 [95% confidence interval (CI): 1.14, 1.22], with an approximately linear association between temperature and hospitalization. Vulnerability to heat-related injuries was more pronounced among males, young (<18 years of age) or middle-aged (45–64 years of age) individuals, and those living in the North. The heatrelated attributable fraction increased from 23.2% in the 2000s to 23.6% in the 2010s, with a corresponding increase in the contribution of humaninduced change over time. In the 2010s, the heat-related attributable fractions for specific causes of injury ranged from 12.4% to 54.4%, with humaninduced change accounting for 6.7% to 10.6% of the burden. DISCUSSION: This nationwide study presents new evidence of significant associations between temperature and cause-specific injury hospitalizations in China and highlights the increasing contribution of human-induced warming to the injury burden.

Objective The objective of this study was to perform a meta-analysis of the minimal clinically important difference (MCID) of the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire and its shortened version (ie, the QuickDASH). Methods MEDLINE, EMBASE, CINAHL, PsycINFO, Web of Science, Cochrane Library, and Scopus were searched up to July 2022. Studies on people with upper limb musculoskeletal disorders that calculated the MCID by anchor-based methods were included. Descriptive and quantitative synthesis was used for the MCID and the minimal detectable change with 90% confidence (MDC90). Fixed-effects models and random-effect models were used for the meta-analysis. I 2 statistics was computed to assess heterogeneity. The methodological quality of studies was assessed with the Consensus-Based Standards for the Selection of Health Measurement Instruments checklist for measurement error and an adaptation of the checklist for the studies on MCID proposed by Bohannon and Glenney. Results Twelve studies (1677 patients) were included, producing 17 MCID estimates ranging from 8.3 to 18.0 DASH points and 8.0 to 18.1 QuickDASH points. The pooled MCIDs were 11.00 DASH points (95% CI = 8.59–13.41; I 2 = 0%) and 11.97 QuickDASH points (95% CI = 9.60–14.33; I 2 = 0%). The pooled MDC90s were 9.04 DASH points (95% CI = 6.46–11.62; I 2 = 0%) and 9.03 QuickDASH points (95% CI = 6.36–11.71; I 2 = 18%). Great methodological heterogeneity in the calculation of the MCID was identified among the primary studies. Conclusion Reasonable MCID ranges of 12 to 14 DASH points and 12 to 15 QuickDASH points were established. The lower boundaries represent the first available measure above the pooled MDC90, and the upper limits represent the upper 95% CI of the pooled MCID. Impact Reasonable ranges for the MCID of 12 to 14 DASH points and 12 to 15 QuickDASH points were proposed. The lower boundaries represent the first available measure above the pooled MDC90, and the upper limits represent the upper 95% CI of the pooled MCID. Information regarding the interpretability of the 2 questionnaires was derived from very different methodologies, making it difficult to identify reliable thresholds. Now clinicians and researchers can rely on more credible data. The proposed MCIDs should be used to assess people with musculoskeletal disorders. Heterogeneity was found related particularly to the anchor levels used in the primary studies. To promote comparability of MCID values, shared rules defining the most appropriate types of anchoring will be needed in the near future. [ABSTRACT FROM AUTHOR]

Background: There are few data on throwing arm and shoulder injury in youth softball athletes, and no data on the influence of sport specialization on injury in softball. Hypothesis: We hypothesized that highly specialized athletes, and pitchers in particular, demonstrating various sport specialization behaviors would be more likely to report an upper extremity overuse injury in the previous 12 months. Study Design: Cross-sectional survey. Level of Evidence: Level 4. Methods: An online, anonymous, cross-sectional survey was distributed to a national sample of female youth softball players between the ages of 12 and 18 years in fall 2021. Topics included were indicators of sport specialization and self-reported injuries to the throwing arm. Results: A total of 1309 participants (mean age, 15.1 ± 1.7 years) completed the survey; 19.4% (N = 254) scored as highly specialized, 69.7% (N = 912) as moderately specialized, and 10.9% (N = 143) with low specialization. Of all participants, 27.3% (N = 357) pitched in the previous year. A minority of all players (43.7%; N = 572) reported arm injury in the previous 12 months, with 45.9% of pitchers (N = 164) reporting the same. Multivariate regression showed increased adjusted odds ratio (aOR) of injury history for athletes playing >30 games per year (aOR, 1.74; 95% CI, 1.26-2.40), participating on a club team (aOR, 3.36; 95% CI,1.85-6.07), and in pitchers participating on club teams (aOR, 2.97; 95% CI, 1.18-7.45). Decreased aOR of injury was noted in those participating in >8 months of softball per year (aOR, 0.25; 95% CI, 0.12-0.51) and in pitchers who were moderately specialized (aOR, 0.39; 95% CI, 0.17-0.92) and playing >8 months per year (aOR, 0.33; 95% CI, 0.11-0.96). Conclusion: This sample provides a large proportion of athletes classified as high or moderately specialized in youth softball (89%). A large proportion (43.7%) of subjects reported arm injury in the past year, and insight into injury risk is provided. The results present conflicting data on the risk versus protective effect of specialization in youth softball athletes. Clinical Relevance: This project is a first step toward understanding sport specialization behavior and its influence on injury in youth softball [ABSTRACT FROM AUTHOR]

Background: Golf is one of the most popular sports in the United States (US) and is played by participants of all ages and skill level. Given the popularity and sport-specific demands on the upper torso, golf poses a considerable risk for upper extremity (UE) injuries. Therefore, the aim of the current study was to (1) determine the incidence rate of UE golf injuries presenting to emergency departments (EDs) in the US, (2) determine the most commonly injured body parts and mechanisms of injury, and (3) compare current injury epidemiology with previous trends in the literature. Hypothesis: Male sex, bimodal age extremes (young and elderly), and utilization of golf carts (vs walking) are associated with a higher incidence of golf-related UE injuries. Study Design: Descriptive epidemiology study. Level of Evidence: Level 3. Methods: The National Electronic Injury Surveillance System (NEISS) is a statistically validated injury surveillance system that collects data from ED visits as a representative probability sample of hospitals in the US. We queried the NEISS for the years 2011 to 2020 to examine the following variables for golf-related UE injuries: sociodemographic, diagnosis, body part, and mechanism of injury. Results: From 2011 to 2020, there were a total of 1862 golf-related UE injuries presenting to participating EDs, which correlates to an estimated 70,868 total injuries. Overall, male golf players were disproportionately affected (69.2%) versus female golf players (30.8%) and the most commonly injured age groups were those aged >60 and 10 to 19 years. The most common injuries included fractures (26.8%), strains/sprains (23.4%), and soft tissue injuries (15.9%). The joints injured most frequently were the shoulder (24.8%), wrist (15.6%), and joints in the hand (12.0%). The most common mechanisms of injury were cart accidents (44.63%), falling/tripping (29.22%), and golf club swinging/mechanics (10.37%). Conclusion: Golf-related UE injuries can be acute or due to chronic overuse. Male athletes >60 years of age were the population most commonly presenting to the ED with a golf-related injury. Further, the shoulder, forearm, and wrist were most commonly injured. These findings are consistent with previous epidemiological trends in the literature. Interventions to reduce the incidence of injury should be sport-specific and focus primarily on equipment and golf cart safety and swing modification to optimize the biomechanical function of the UEs. Clinical Relevance: Our findings indicate that golf-related injury prevention programs should target UE injuries, particularly among young (<19) and older (>60 years) golfers with poor swing mechanics.

Background: Axillary-subclavian venous thrombosis (ASVT) is a type of upper extremity deep vein thrombosis (UEDVT). UEDVTs are classified as either primary or secondary depending on their etiology. Although uncommon, clinicians should be aware of the clinical presentation of UEDVT as timely diagnosis and early treatment is critical in preventing possible postthrombotic complications. Case presentation: We report a rare case of axillarysubclavian and internal jugular vein thrombosis in the absence of clear risk factors in a 78-year-old male weightlifter who presented to the office with two-week duration of left upper extremity pain and swelling following strenuous exercise at the gym. Summary: The combination of unusual thrombi location, in addition to the unusual absence of existing thoracic-outlet compression or indwelling medical hardware, makes our case of UEDVT especially uncommon. Clinicians should be aware of this rare disease due to the debilitating effects both in the short and long term. [ABSTRACT FROM AUTHOR]

The purpose of the present study was to characterize the incidence, injury characteristics, and outcomes of patients presented to four trauma facilities located in the upper Midwest with tractor-related agricultural injuries. We performed a retrospective review of the facility level trauma registries of four trauma centers located in North Dakota, South Dakota, and Minnesota between January 1, 2010 and December 31, 2021. We characterized the incidence, severity and outcomes of traumatic tractor-related agricultural injuries for pediatric and adult patients. We described the nature of these injuries by severity, anatomical site, type, age, sex, and length of stay (LoS). Injury severity was evaluated using Injury Severity Score (ISS) and Abbreviated Injury Scale (AIS). Findings indicated that farmers aged 65 and older experience polytraumatic, severe tractor-related agricultural injuries and fatalities. Of the 177 tractor patients analyzed, 40 patients were between the ages of 65 and 74 years and 45 patients were 75 and over. Male farmers aged 65 and older are injured year-round, many are discharged to skilled nursing facilities for additional care, are spending more time in the hospital, and have the highest rate of critical injuries out of all age groups. Moreover, the patients who died as a result of tractor-related agricultural injuries were men over 65 years. The most common tractor-related agricultural injuries include falls from tractors (n = 53), struck by object falling/propelled from tractor (n = 25), rollovers (n = 26), and runovers (n = 24). Falls from tractors accounted for 33% of all tractor-related upper extremity fractures, 36% of head injuries and 29% of chest injuries. The findings from this study indicate that tractor-related agricultural injuries represent a significant problem in the upper Midwest. Older, male farm workers experience a higher incidence of tractor-related agricultural injuries, and all tractor-related fatalities occurred in individuals 65 years of age and older. These results underscore the need for further investigation into aging-related farm safety issues. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to predict and manage physical injuries caused by gym equipment and facilities using the SVM algorithm. Method: This study was of a developmental-applied type. The snowball method was used to select the subjects. Subjects were asked to answer the questionnaire online and send it to friends and acquaintances of athletes. The validity of the instrument was confirmed through the opinions of university professors and convergent validity. Cronbach's alpha was used to check reliability. The sample questionnaire included 612 athletes in the age group of 18 to 60 years. 158 people were healthy, 54 people had head injuries, 211 people had leg injuries, and 189 people had hand injuries. The SVM algorithm was used to classify people. In addition, MATLAB software version 2022 was used for data analysis. The evaluation was conducted based on the clutter matrix and accuracy criteria. Results: The results showed that the SVM algorithm can predict head, arm and leg injuries with 74.6% accuracy and 73.2% accuracy, respectively. Conclusion: This study showed that by discovering hidden patterns and relationships in the data, this algorithm can probably be used correctly to improve the quality of sports facilities management to prevent physical injuries of athletes.

Background: The epidemiology of musculoskeletal injuries at the Australian Open, Wimbledon, and US Open tennis tournaments has been investigated in recent studies; however, there is no published literature on the incidence of musculoskeletal injuries at the French Open. Purpose: To describe the incidence, location, and type of musculoskeletal injuries in tennis players during the French Open tournament from 2011 to 2022. Study Design: Descriptive epidemiology study. Methods: A review was performed of all injuries documented by a multidisciplinary medical team during the French Open from 2011 to 2022. All musculoskeletal injuries that occurred during the main draw of the female and male singles or doubles matches were included. Descriptive statistics were used to summarize the data. Injury locations were grouped into regions as well as into upper limb, trunk, and lower limb. Results: In total, there were 750 injuries in 687 tennis players, resulting in a mean of 62.5 injuries per tournament; however, there were no obvious trends in injury incidence over the time frame evaluated. The number of injuries in female and male players was similar (392 vs 358, respectively). The most common injury regions were the thigh/hip/pelvis (n = 156), ankle/foot (n = 114), and spine (n = 103). The most common injury types were muscle-related (n = 244), tendon-related (n = 207), and joint-related (n = 163), and the most affected muscles were the adductors (n = 45), rectus abdominis (n = 38), and lumbar muscles (n = 25). Conclusion: Over the 12-year period from 2011 to 2022 female and male players experienced similar numbers of musculoskeletal injuries, with most injuries occurring in the lower limbs compared with the upper limbs and trunk.

Collegiate baseball players with professional aspirations often participate in summer leagues; foremost among them is the Cape Cod Baseball League (CCBL). Injuries acquired during the collegiate baseball season can be carried into the CCBL season and vice versa. To assess the history of throwing arm injury and current functionality in midseason CCBL players. Cross-sectional study. Online questionnaire. A total of 123 CCBL players participated. Qualifying athletes were ≥18 years old and were rostered CCBL players with remaining collegiate eligibility. After collecting background information, we used the Kerlan-Jobe Orthopaedic Clinic (KJOC) Shoulder and Elbow questionnaire to assess the history of throwing arm injury and current functionality. The maximum KJOC score is 100.0; higher scores correspond with greater functionality. The mean KJOC score was 86.6 ± 14.5 (n = 92); 24.5% (23/94) of players reported a prior diagnosis of throwing arm injury other than a strain or sprain. A total of 49 (49/96, 51.0%) players had undergone rehabilitation for a throwing arm injury, and 7 (7/96, 7.3%) had experienced a medical procedure. Players with no previous treatment (n = 41, mean KJOC score = 88.9 ± 19.0) more frequently demonstrated KJOC scores of ≥90 than players with such treatment (n = 55, 80.9 ± 17.1; P <.001). The 18 players with time-loss arm injury in the last year had lower mean KJOC scores (71.3 ± 20.0) than players with no injury or time loss (90.3 ± 9.8; P <.001). Similarly, players who reported current arm trouble (n = 15) had lower KJOC scores (71.6 ± 17.5) than players with healthy arms (89.5 ± 11.9; P <.001). The average KJOC score of the CCBL players was <90, with particularly low scores in athletes with prior arm injury and treatment. [ABSTRACT FROM AUTHOR]

Orthopedic costs associated with gunshot wounds (GSWs) totaled approximately USD 510 million from 2005 to 2014. Previous studies have identified differences in injuries associated with self-inflicted (SI) GSWs; however, there remains a gap in understanding injury patterns. This study aims to expand upon the current literature and shed light on injury patterns and outcomes associated with SI vs. non-self-inflicted (NSI) GSWs. This is a retrospective cohort study of upper extremity GSWs from January 2012 to December 2022. Data were analyzed using the two-sample t-test, Pearson's chi-squared test, and Fisher's exact test. SI GSWs tended to be high-velocity GSWs and occurred more often in distal locations compared to NSI GSWs (p = 0.0014 and p < 0.0001, respectively). SI GSWs were associated with higher Gustilo–Anderson (GA) and Tscherne classifications (p < 0.0001 and p = 0.0048, respectively) and with a greater frequency of neurovascular damage (p = 0.0048). There was no difference in fracture rate or need for operative intervention between the groups. GA and Tscherne classifications were associated with the need for and type of surgery (p < 0.0001), with a higher classification being associated with more intricate operative intervention; however, GSW velocity was not associated with operative need (p = 0.42). Our findings demonstrate that velocity, wound grading systems, and other factors are associated with the manner in which GSWs to the upper extremity are inflicted and may thus have potential for use in the prediction of injury patterns and planning of trauma management and surgical intervention.

Recent data reveal an increase in the likelihood of staff injury for those working in the health care and social assistance industries (United States Bureau of Labor Statistics, 2021). Without information summarizing variables pertaining to staff injury in behavior‐analytic service settings, organizational leaders risk the safety of staff they employ. Despite the social relevance, few studies concerning the types of client‐related staff injuries have been published. The purpose of this survey was to gather data on the cause, type, bodily location of, and treatment required for staff injury by surveying organizations that serve individuals with autism spectrum disorder. Respondents ranked the leading cause of injury as client‐to‐staff interactions, type of injury as bite, location of injury as arm, and the most common treatment required as on‐site first aid. These initial data could assist in the identification of job tasks that may be associated with increased risk of injury, potential ramifications of client‐inflicted injuries on staff performance and organizational outcomes, and how to address injuries in settings within an injury‐prone industry. Implications and future research ideas are also discussed. [ABSTRACT FROM AUTHOR]

Handball is a sport that involves high-intensity actions throughout the game, such as sprints, jumps, landings, and high-speed, repeated throws. This, along with competitive and tactical factors, congested schedules, and the need to maintain a high level of performance throughout the season, contributes to a high injury rate. This study aimed to analyse ligament injuries in a professional handball team over six consecutive seasons. A total of 68 elite male Spanish handball players participated, with 54 time-loss injuries (i.e., injuries involving at least one day of absence) observed during this study period. Ligament injury information was recorded following the International Olympic Committee consensus statement. The overall incidence was 0.89 ligament injuries per 1000 h of exposure. Additionally, a higher incidence and burden of ligament injuries was observed during match-play compared to training. Most ligament injuries were classified as minor or moderate (i.e., 79.63% of the total), and 46.29% were reinjuries. A significantly higher incidence of ligament injuries was suffered in the lower limbs compared to the upper limbs (0.81 vs. 0.08 ligament injuries per 1000 h; p < 0.001). Specifically, the highest incidence was observed in the anterior talofibular ligament of the ankle (0.57 injuries per 1000 h of exposure), while the greatest burden was related to the anterior cruciate ligament (24.08 absence days per 1000 h of exposure). This study provides an overview of ligament injuries among professional handball players, highlighting the need to implement strategies with positive effects during competition (e.g., specific activation strategies or training programmes based on strength and balance) and to reduce injury recurrences.

Vascular injuries of the upper extremity are usually associated with nerve damage. Neuropraxis or neurotmesis can cause atrophy of an entire group of muscles. We describe a unique case of a 24-yearold male with an isolated atrophy of the long head of triceps, resulting from a piercing arm injury in his childhood. Early post-operative examination showed acute radial palsy (due to a hematoma), which resolved over time with what seemed a full return to normal function. The patient engaged in bodybuilding 14 years post-trauma. Only after the patient had gained significant muscle mass did the difference in size between triceps brachii muscles become visible. We performed a series of imaging examinations to diagnose and determine the extent of the atrophy. USG and MRI have shown an atrophic long head of triceps brachii, of atypical presentation, intact muscular insertions and an unaffected main course of the radial nerve. Subsequently, the patient underwent a strength test to determine the level of strength deficit. We posit that the most likely aetiology for the atrophy is neurological, with the damage to the radial nerves branch to the long head of the triceps brachii resulting from either direct cutting or pressure exerted by the hematoma.
