ABSTRACT
This report updates previous analyses of health care burden distributions among active and reserve component service members of the U.S. Armed Forces in deployed settings. Musculoskeletal disorders in combination with administrative and other health services (ICD-10 "Z" codes) accounted for more than half of all medical encounters in 2023 among service members deployed to the U.S. Central Command (CENTCOM) and Africa Command (AFRICOM). Three common injury conditions occurred among male and female service members deployed to U.S. CENTCOM and U.S. AFRICOM: other back problems, arm and shoulder injuries, and knee injuries.

BACKGROUND: The management of upper limb injury is aimed at a timely return to work, and other activities of daily living. The modified hand injury severity score (MHISS) has been found to predict a return to work. Upper limb injuries are common in our subregion, but there is little or no data on the time to return to work. AIM: This study, therefore, aimed to determine the prevalence of return to work and to identify the predictors of time to return to work following reconstruction of upper limb injuries. METHOD: This was a cross-sectional analytic study carried out between April 2022 and March 2023. The statistical test was at a confidence interval of 95%, and statistical significance set at a P value of <0.05. RESULT: A total of 49 upper-limb-injured patients had reconstruction in the time under review. Male-to-female ratio was 4.4:1. The mean MHISS was 87.9 ± 79.2. Of the 43 patients who participated in the return-to-work analysis, 41.9% had returned to work, with a mean time of 14.3 ± 10.5 weeks. Work-related injuries (r = 0.357, P = 0.019), male gender (r = 0.354, P = 0.020), and MHISS (r = 0.333, P = 0.029) correlated significantly with late return to work. On multiple logistic regression, work-related injuries (ß =0.321, P = 0.037), MHISS (ß =0.376, P = 0.032), and male gender (ß =0.326, P = 0.044) were found to be the significant predictors of late return to work. CONCLUSION: There is a low prevalence of return to work, with a high mean time to return. Work-related injuries, MHISS, and male gender are significant predictors of time to return to work.

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.

Reports of children's play-related injuries have remained stagnant according to epidemiology studies of the past 3 decades. This article provides a unique look into the context of playground injuries within an entire school district, demonstrating the prevalence of these injuries. This study reports that playgrounds are the leading location of school injury, comprising one-third of all elementary school injuries. This study found that while head/neck injuries were the most commonly injured body region within the playground environment, the proportion of head/neck injuries decreased with age, whereas the proportion of extremity injuries increased with age. At least 1 upper extremity injury required outside medical attention for every 4 that were treated on-site, making upper extremity injuries roughly twice as likely to require outside medical attention as injuries to other body regions. The data in this study are useful for interpreting injury patterns in the context and evaluation of existing safety standards for playgrounds.

Upper extremity (UE) fractures are prevalent age-related fractures, and stair-associated falls are a common mechanism for these injuries. Our study has identified an increasing incidence of stair-related UE fractures and associated hospitalization rates among the older United States population between 2012-2021. Targeted prevention efforts should be implemented by health systems. INTRODUCTION: To analyze United States (US) emergency department trends in upper extremity stair-related fractures among older adults and investigate risk factors associated with hospitalization. METHODS: We queried the National Electronic Injury Surveillance System (NEISS) for all stair-related fracture injuries between 2012 and 2021 among adults 65 years or older. The US Census Bureau International Database (IDB) was analyzed to calculate incidence rates. Descriptive analysis, linear regression analysis, and multivariate regression analysis were used to interpret the collected data. RESULTS: Our analysis estimated 251,041 (95% CI: 211,678-290,404) upper extremity stair-related fractures among older adults occurred between 2012 and 2021. The primary anatomical locations were the humeral shaft (27%), wrist (26%), and proximal humerus (18%). We found a 56% increase in injuries (R2 = 0.77, p < 0.001), 7% increase in incidence per 100,000 persons (R2 = 0.42, p < 0.05), and an 38% increase in hospitalization rate (R2 = 0.61, p < 0.01) during the 10-year study period. Women sustained the majority of fractures (76%) and most injuries occurred in homes (89%). Advanced age (p < 0.0001), males (p < 0.0001), proximal humerus fractures (p < 0.0001), humeral shaft fractures (p < 0.0001), and elbow fractures (p < 0.0001) were associated with increased odds of hospitalization after injury. CONCLUSION: Stair-related UE fracture injuries, incidence, and hospitalization rates among older adults are increasing significantly, particularly among older females. Improving bone health, optimizing functional muscle mass, and "fall-proofing" homes of older age groups may help mitigate the rising incidence of these injuries.

BACKGROUND: Arm injuries are commonly encountered in baseball as young athletes play into adulthood. The purpose of this study was to examine the incidence of arm injury and risk for surgery in adolescent baseball players followed over a 10-year period from scholastic, age-group, and travel baseball leagues through their highest level of competition. METHODS: A prospective study was conducted enrolling middle and high school baseball players in 2010-2012, then followed for 10 years or until retirement from competitive baseball. Players were included if fully participating in team activities at the time of preseason study enrollment. Players with prior arm (shoulder or elbow) surgery or those diagnosed with time loss arm injury within the past year were excluded. Only shoulder and elbow overuse problems resulting in time-loss from sport and medical attention from a sports medicine physician or orthopedic surgeon were documented as injuries in this study. Musculoskeletal overuse injuries were classified based on the orchard injury classification system. Incidence proportion and risk ratio (RR) and 95% confidence intervals (CIs) for initial injury and injuries requiring surgery were calculated. RESULTS: A total of 261 pitchers (age: 14.2 ± 2.6 years; follow-up: 4.2 ± 2.7 years) were enrolled. Twenty percent of the cohort was followed for ≥7 years. The overall injury incidence was 25.6/100 athletes (95% CI 21-31) with a cumulative surgical incidence of 5.4/100 athletes (95% CI 3.2-8.8). The risk of experiencing shoulder injury (n = 25) and elbow injury (n = 38) were similar (n = 38) (RR 0.7, 95% CI 0.4-1.1). The athletes also presented with a similar frequency of requiring surgery regardless of the injured body part. However, the risk of surgery in those playing beyond the high school level was 4.3 times greater (95% CI 1.2-15.0) than those only playing high school. CONCLUSION: This is the first study to follow a large cohort of youth baseball players as they progress, showing a relatively high arm injury incidence. Shoulder and elbow injury incidence was similar but surgical risk increased playing beyond high school, specifically for the elbow. The high injury frequency and burden of care required by young baseball players as reported in this study is concerning, and strategies to reduce injury should be investigated.

PURPOSE: To perform an analysis of electric scooter (e-scooter)-related upper limb fractures (ULFs), which have increased dramatically in parallel with the rapid rise in the use of e-scooters and shared e-scooter services in recent years. METHODS: We retrospectively reviewed the medical charts of e-scooter-related emergency department visits between January 2017 and January 2020 at a level I trauma center. All patients with ULFs were included in the study, and their data were analyzed for demographics, fracture diagnosis, associated injuries, and required surgical treatment. RESULTS: This study included 356 patients (50% men) with 458 ULFs, of which 23 (5%) were open fractures. The mean age of the cohort was 32.9 years (standard deviation, 10.1 years). The most common mechanism of injury was rider fall (92.1%). The nondominant hand was injured in 53.1% of cases, and 32.1% of all fractures were treated with surgery. A total of 120 (33.7%) patients sustained more than 1 ipsilateral ULF, and 27 (7.6%) patients had a concomitant contralateral ULF. Radial head fracture was the most common fracture type (n = 123, 26.8%), of which 16 (13%) were bilateral. The fifth ray was injured most frequently among the metacarpal and phalangeal fractures (n = 33, 47.1%). Most of the nonextremity-associated injuries were those of the head and maxillofacial bones. CONCLUSIONS: The most common ULF associated with e-scooters was the radial head fracture. Physicians should be alert to and seek associated fractures during initial assessments of e-scooter-related upper limb injuries. Further investigation may be warranted to evaluate the effectiveness of protective measures in reducing the number of injuries. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Glenohumeral internal rotation deficit (GIRD) and weakness in prone external rotation are risk factors for shoulder and elbow injuries in high school baseball pitchers. While a shoulder-stretching prevention program to improve GIRD decreases the injury rate, the effects of external rotation strength remain unclear. This non-inferiority (NI) study investigates the hypothesis that external rotation strength training is not inferior to sleeper stretching for shoulder and elbow injury prevention in high school baseball pitchers. Participants were randomly allocated to the stretching (n = 62; active control group) and muscle-training (n = 51) groups. Specific exercises were performed each night. Elbow and shoulder injuries were monitored for 150 days. Kaplan-Meier survival curves were generated, and the hazard ratios (HRs) for injury occurrence were calculated using multivariate Cox regression. The log-rank test was used to compare the injury-free time. A one-sided NI test using a fixed NI margin was performed (significance level, P = 0.025). The injury rates were 22.6% (n = 14) in the stretching group and 9.8% (n = 5) in the muscle-training group. The muscle-training group had a lower injury rate (P < 0.001) and a lower risk of injury than the stretching group (HR = 0.489). Therefore, external rotation muscle strength training is not inferior to stretching for preventing baseball-related arm injuries.

OBJECTIVES: To (1) evaluate an injury risk model that included modifiable and nonmodifiable factors into an arm injury risk prediction model in Minor League Baseball (MiLB) pitchers and (2) compare model performance separately for predicting the incidence of elbow and shoulder injuries. DESIGN: Prospective cohort. METHODS: A 10-year MiLB injury risk study was conducted. Pitchers were evaluated during preseason, and pitches and arm injuries were documented prospectively. Nonmodifiable variables included arm injury history, professional experience, arm dominance, year, and humeral torsion. Modifiable variables included BMI, pitch count, total range of motion, and horizontal adduction. We compared modifiable, nonmodifiable, and combined model performance by R2, calibration (best = 1.00), and discrimination (area under the curve [AUC]; higher number is better). Sensitivity analysis included only arm injuries sustained in the first 90 days. RESULTS: In this study, 407 MiLB pitchers (141 arm injuries) were included. Arm injury incidence was 0.27 injuries per 1000 pitches. The arm injury model (calibration 1.05 [0.81-1.30]; AUC: 0.74 [0.69-0.80]) had improved performance compared to only using modifiable predictors (calibration: 0.91 [0.68-1.14]; AUC: 0.67 [0.62-0.73]) and only shoulder range of motion (calibration: 0.52 [0.29, 0.75]; AUC: 0.52 [0.46, 58]). Elbow injury model demonstrated improved performance (calibration: 1.03 [0.76-1.33]; AUC: 0.76 [0.69-0.83]) compared to the shoulder injury model (calibration: 0.46 [0.22-0.69]; AUC: 0.62 [95% CI: 0.55, 0.69]). The sensitivity analysis demonstrated improved model performance compared to the arm injury model. CONCLUSION: Arm injury risk is influenced by modifiable and nonmodifiable risk factors. The most accurate way to identify professional pitchers who are at risk for arm injury is to use a model that includes modifiable and nonmodifiable risk factors.

BACKGROUND: Currently, there are few studies that have evaluated the relationship between a lower extremity or trunk injury (kinematic chain) and subsequent arm injury. The purpose of this study was (1) to investigate the relationship between initial kinematic chain (lower extremity or trunk) injury and subsequent arm injury; and (2) to investigate the relationship between initial shoulder or elbow injury and subsequent arm injury. METHODS: A 7-year prospective injury risk study was conducted with Minor League Baseball pitchers. Pitches, pitching appearances, athlete exposures (AEs), and arm injuries (≥1-day time loss) were documented throughout the season. Cox survival analyses with 95% confidence intervals (95% CIs) were performed. Confounders controlled for included age, body mass index, arm dominance, pitching role, previous arm injury, number of pitching appearances, and seasonal pitch load. RESULTS: A total of 297 pitchers participated (total player days = 85,270). Arm injury incidence was 11.4 arm injuries/10,000 AEs, and kinematic chain incidence was 5.2 injuries/10,000 AEs. Pitchers who sustained a kinematic chain injury demonstrated a greater hazard (2.6 [95% CI: 1.2, 5.6], P = .019) of sustaining an arm injury. Pitchers who sustained an initial shoulder injury demonstrated a greater hazard (9.3 [95% CI: 1.1, 83], P = .047) of sustaining a subsequent shoulder or elbow injury compared with pitchers who sustained an initial elbow injury. CONCLUSIONS: Pitchers who sustained an initial lower extremity or trunk injury demonstrated an increased subsequent arm injury hazard compared with pitchers who did not. Pitchers who sustained an initial shoulder injury demonstrated a greater hazard of sustaining a subsequent arm injury compared with pitchers who sustained an initial elbow injury. However, this secondary analysis should be interpreted with caution. Clinicians should monitor risk with workload accumulation, which may be related to pitching compensatory strategies in a fatigued state. Pitchers who sustain a shoulder injury should be evaluated and perform both shoulder and elbow rehabilitation strategies before return to sport.

INTRODUCTION: During the emergence of the SARS-CoV-2 (COVID-19) pandemic, there were substantial changes in United States (U.S.) emergency department (ED) volumes and acuity of patient presentation compared to more recent years. Thus, the purpose of this study was to characterize the incidence of specific upper extremity (UE) injuries presenting to U.S. EDs during the COVID-19 pandemic and analyze trends across age groups and rates of hospital admission compared to years prior. METHODS: The National Electronic Injury Surveillance System (NEISS) database was queried to identify patients who presented to U.S. EDs for an UE orthopaedic injury between 2016 and 2020. Chi-square analysis and logistic regression were used to assess for differences in ED presentation volume and hospital admissions between pre-pandemic (2016 through 2019) and during-pandemic (2020) times. RESULTS: These queries returned 285,583 cases, representing a total estimate of 10,452,166 injuries presenting to EDs across the U.S. The mean incidence of UE orthopaedic injuries was 640.2 (95% CI, 638.2-642.3) injuries per 100,000 person-years, with the greatest year to year decrease in incidence occurring between 2019 and 2020 (20.1%). The largest number of estimated admissions occurred in 2020, with a total 135,018 admissions (95% CI, 131,518-138,517), a 41.6% increase from the average number of admissions between 2016 and 2019. CONCLUSION: There was a 20.1% decrease in the incidence of UE orthopaedic injuries presenting to EDs after the start of the COVID-19 pandemic with a concomitant 41.2% increase in the number of hospital admissions from the ED in 2020 compared to recent pre-pandemic years. We speculate that at least some elective, semi-elective or urgent ambulatory surgeries were canceled or delayed due to the pandemic and were subsequently directed to the ED for admission. Regardless of the cause of increased UE orthopaedic admissions, policy planners and administrators should be aware of the additional stresses placed on already burdened ED and inpatient services. LEVEL OF EVIDENCE: Level III - Retrospective Cohort Study.

CONTEXT: How different pitching roles affect the risk of arm injury in professional pitchers is currently unclear. OBJECTIVES: To investigate differences between professional baseball starting and relief pitchers in the hazard of (1) arm injury and (2) elbow and shoulder injury. DESIGN: Prospective cohort study. SETTING: Minor League Baseball (MiLB) from 2013 to 2019. PATIENTS OR OTHER PARTICIPANTS: Pitchers in MiLB. MAIN OUTCOME MEASURE(S): Pitchers were followed for the entire MiLB season, and athlete-exposures and injuries were recorded. Risk ratios and risk difference were calculated between starting and relieving MiLB pitchers. A Cox survival analysis was then performed in relation to time to arm injury between starting and relieving MiLB pitchers. Subgroup analyses were conducted for elbow and shoulder injuries. RESULTS: A total of 297 pitchers were included, with 85â270 player-days recorded. The incidence of arm injuries was 11.4 per 10â000 athlete-exposures. Starting pitchers demonstrated a greater risk ratio (1.2 [95% CI = 1.1, 1.3]), risk difference (13.6 [95% CI = 5.6, 21.6]), and hazard of arm injury (2.4 [95% CI = 1.5, 4.0]) than relief pitchers. No differences were observed for the hazard of elbow injury between starting and relief pitchers (1.9; 95% CI = 0.8, 4.2). Starting pitchers had a greater hazard of shoulder injury than relief pitchers (3.8 [95% CI = 2.0, 7.1]). CONCLUSIONS: Starting pitchers displayed a 2.4 times greater hazard of arm injury than relief pitchers. Subgroup analyses indicated that starters exhibited a greater hazard of shoulder injury than relievers, but no differences occurred for the hazard of elbow injury. However, due to the wide CIs, these subgroup analyses should be interpreted with caution. Clinicians may need to consider cumulative exposure and fatigue and how these factors relate to different pitching roles when assessing the risk of pitching arm injury.

INTRODUCTION: It is well known that trampolines can be a particular source of danger, especially in children. We sought to examine the profile of those patients with trampoline injuries. We hypothesized there would be certain injury patterns predicative of trampoline injuries. METHODS: All patients submitted to Pennsylvania Trauma Outcome Study database from 2016 to 2018 were analyzed. Trampoline injury was determined by ICD-10 activity code. Injury patterns in the form of abbreviated injury scale body regions were examined. Patient demographics and clinical variables were compared between those with trampoline injury vs those without. RESULTS: There were 107 patients with a trampoline injury. All of these patients were discharged alive and had a blunt mechanism of injury. The most common injury type was injury to the extremities (n=90,[84.1%]) with 54(50.5%) upper extremity injuries and 36(33.6%) lower extremity injuries. Ten (9.35%) patients had injury to the spine and five (4.67%) had head injury. Those with trampoline injuries were significantly younger (13y vs. 48.6y) and more likely to be white or of Hispanic ethnicity. Almost half of the patients injured (49.5%) were under 10 years. Patients with trampoline injuries had significantly lower Injury Severity Scores and significantly higher shock index. DISCUSSION: The majority of patients with trampoline injuries had injury to an extremity. These results help better understand the demographic, physiologic, and anatomic patterns surrounding trampoline injuries. Current government standards recommend that no child under age six should use a full-sized trampoline; however, based of this study, we advise that this age be increased to ten.

BACKGROUND: Traumatic peripheral nerve injuries cause chronic pain, disability, and long-term reductions in quality of life. However, their incidence after extremity trauma remains poorly understood. METHODS: The IBM® MarketScan® Commercial Database from 2010 to 2015 was used to identify patients aged 18 to 64 who presented to emergency departments for upper and/or lower extremity traumas. Cumulative incidences were calculated for nerve injuries diagnosed within 2 years of trauma. Cox regression models were developed to evaluate the associations between upper extremity nerve injury and chronic pain, disability, and use of physical therapy or occupational therapy. RESULTS: The final cohort consisted of 1 230 362 patients with employer-sponsored health plans. Nerve injuries were diagnosed in 2.6% of upper extremity trauma patients and 1.2% of lower extremity trauma patients. Only 9% and 38% of nerve injuries were diagnosed by the time of emergency department and hospital discharge, respectively. Patients with nerve injuries were more likely to be diagnosed with chronic pain (hazard ratio [HR]: 5.9, 95% confidence interval [CI], 4.3-8.2), use physical therapy services (HR: 10.7, 95% CI, 8.8-13.1), and use occupational therapy services (HR: 19.2, 95% CI, 15.4-24.0) more than 90 days after injury. CONCLUSIONS: The incidence of nerve injury in this national cohort was higher than previously reported. A minority of injuries were diagnosed by emergency department or hospital discharge. These findings may improve practitioner awareness and inform public health interventions for injury prevention.

BACKGROUND: Baseball is one of the most popular boy's youth sports, and there has been a rise in the rates of certain overuse injuries among players. Specialization has been identified as a risk factor for overuse injury in high school athlete populations, but there is little understanding of the prevalence or consequences of sport specialization in Little League baseball players. HYPOTHESIS: Sport specialization will be highly prevalent among Little League baseball players and specialization will be associated with worse throwing arm health. STUDY DESIGN: Cross-sectional study. LEVEL OF EVIDENCE: Level 3. METHODS: A total of 246 Little League baseball players (male; N = 241; age, 9.5 ± 1.6 years) between 7 and 12 years old completed an anonymous, online questionnaire with their parent's assistance. The questionnaire consisted of participant demographics and baseball participation information, including sport specialization status and the Youth Throwing Score (YTS), a valid and reliable patient-reported outcome measure for youth baseball players. RESULTS: Only 29 (11.8%) players met the criteria for high specialization. Approximately one-third of all players (n = 77; 31.3%) reported participating in baseball year-round or receiving private coaching outside of their league (n = 81; 32.9%). Highly specialized athletes demonstrated worse scores on the YTS on average compared with low-specialization athletes (mean [SE]: 56.9 [1.6] vs 61.1 [1.2]; P = 0.01). Similarly, pitching in the previous year (P < 0.01) or traveling overnight regularly for showcases (P = 0.01) were associated with a worse score on the YTS. CONCLUSION: While the prevalence of high sport specialization was low among Little League baseball players, other behaviors associated with specialization such as year-round play and the receiving of private coaching were more common. Highly specialized Little League players demonstrated worse throwing arm health compared with low-specialization players. CLINICAL RELEVANCE: Little League players and their parents may represent a potential target audience for dissemination campaigns regarding sport specialization.

BACKGROUND: Evidence suggests that shoulder and elbow injuries account for 31% to 37% of all National Collegiate Athletic Association (NCAA) baseball injuries, and up to 69% of NCAA baseball injuries are the result of noncontact and overuse mechanisms. Early sport specialization may contribute to the high rates of upper extremity injuries in college baseball players. HYPOTHESIS: Higher specialization by age 13 years would be associated with worse subjective throwing arm function and a greater history of shoulder and elbow injury. STUDY DESIGN: Cohort study. LEVEL OF EVIDENCE: Level 2. METHODS: Survey data were collected from college baseball players (N = 129) during midseason of the spring 2019 baseball season. Participants were stratified in low, moderate, and high specialization groups based on a 3-criteria sports specialization questionnaire. Participants' throwing arm function was measured using the Functional Arm Scale for Throwers and the Kerlan-Jobe Orthopaedic Clinic shoulder and elbow questionnaires. Participants' history of a shoulder or elbow injury that resulted in missing ≥2 weeks of baseball activity at any point in their baseball career was also collected. RESULTS: The high specialization group reported worse subjective throwing arm function on the Functional Arm Scale for Throwers questionnaire than the low (P = 0.03) and moderate (P = 0.01) specialization groups. The high specialization group was over 5 times more likely to report a history of shoulder injury than the moderate (odds ratio [OR] = 5.42; 95% CI [1.71, 17.2]; P = 0.004) and low (OR = 5.20; 95% CI [1.87, 14.5]; P = 0.002) specialization groups, and over 3 times more likely to report a history of elbow injury than the moderate specialization group (OR = 3.77; 95% CI [1.05, 13.6]; P = 0.04). CONCLUSION: College baseball players that were highly specialized by age 13 years reported worse subjective throwing arm function and were more likely to have a history of upper extremity injury than players that were moderate or low specialization. CLINICAL RELEVANCE: Early specialization in baseball may be detrimental to long-term upper extremity health in college baseball players.

PURPOSE: The aim of this study was to evaluate changes in both mechanism and diagnoses of injuries presenting to the orthopaedic department during this lockdown period, as well as to observe any changes in operative case-mix during this time. METHODS: A study period of twelve weeks following the introduction of the nationwide "lockdown period", March 23rd - June 14th, 2020 was identified and compared to the same time period in 2019 as a "baseline period". A retrospective analysis of all emergency orthopaedic referrals and surgical procedures performed during these time frames was undertaken. All data was collected and screened using the 'eTrauma' management platform (Open Medical, UK). The study included data from a five NHS Foundation Trusts within North West London. A total of 6695 referrals were included for analysis. RESULTS: The total number of referrals received during the lockdown period fell by 35.3% (n=2631) compared to the same period in 2019 (n=4064). Falls remained proportionally the most common mechanism of injury across all age groups in both time periods. The proportion sports related injuries compared to the overall number of injuries fell significantly during the lockdown period (p<0.001), however, the proportion of pushbike related accidents increased significantly (p<0.001). The total number of operations performed during the lockdown period fell by 38.8% (n=1046) during lockdown (n=1732). The proportion of patients undergoing operative intervention for Neck of Femur (NOF) and ankle fractures remained similar during both study periods. A more non-operative approach was seen in the management of wrist fractures, with 41.4% of injuries undergoing an operation during the lockdown period compared to 58.6% at baseline (p<0.001). CONCLUSION: In conclusion, the nationwide lockdown has led to a decrease in emergency orthopaedic referrals and procedure numbers. There has been a change in mechanism of injuries, with fewer sporting injuries, conversely, there has been an increase in the number of pushbike or scooter related injuries during the lockdown period. NOF fractures remained at similar levels to the previous year. There was a change in strategy for managing distal radius fractures with more fractures being treated non-operatively.

Psychiatric disorders are a common cause of disability and represent an important risk factor for upper-extremity trauma. The review provides an overview of psychiatric illnesses as both contributors and sequelae of 4 major injury patterns: self-inflicted wrist lacerations, self-amputation, upper-extremity fractures, and burns. The authors develop a multidisciplinary model for upper-extremity surgeons to care for patients with psychiatric disorders, with an overview of capacity assessment, optimal psychiatric comanagement, and collaboration with allied health professionals.

Background: Upper extremity injuries represent one of the most common pediatric conditions presenting to emergency departments (EDs) in the United States. We aim to describe the epidemiology, trends, and costs of pediatric patients who present to US EDs with upper extremity injuries. Methods: Using the National Emergency Department Sample, we identified all ED encounters by patients aged <18 years associated with a primary diagnosis involving the upper extremity from 2008 to 2012. Patients were divided into 4 groups by age (≤5 years, 6-9 years, 10-13 years, and 14-17 years) and a trauma subgroup. Primary outcomes were prevalence, etiology, and associated charges. Results: In total, 11.7 million ED encounters were identified, and 89.8% had a primary diagnosis involving the upper extremity. Fracture was the most common injury type (28.2%). Dislocations were common in the youngest group (17.7%) but rare in the other 3 (range = 0.8%-1.6%). There were 73.2% of trauma-related visits, most commonly due to falls (29.9%); 96.9% of trauma patients were discharged home from the ED. There were bimodal peaks of incidence in the spring and fall and a nadir in the winter. Emergency department charges of $21.2 billion were generated during the 4 years studied. While volume of visits decreased during the study, associated charges rose by 1.21%. Conclusions: Pediatric upper extremity injuries place burden on the economy of the US health care system. Types of injuries and anticipated payers vary among age groups, and while total yearly visits have decreased over the study period, the average cost of visits has risen.

INTRODUCTION: During the SARS-COV-2 pandemic and consequent government measures to prevent the overwhelming of public hospitals, emergency department (ED) orthopaedic turnout was significantly altered. This study compared the turnout of patients with upper extremity (UE) and hand & wrist (H&W) emergencies during the SARS-COV-2 pandemic, with the same period of 2019, in the public and private sector. MATERIAL-METHODS: Data from a two-month period [March 23, 2020 (application of severe restrictions of civilian circulation) to May 18, 2020 (two weeks after lockdown cessation)] were collected from a public-university hospital and a private hospital and were compared with data from the same "normal" period in 2019. RESULTS: During the pandemic, the number of patients with orthopaedic, UE, and H&W problems was significantly reduced by 57.09%, 49.77%, 49.92% respectively (p<0.001) compared to 2019. However, the ratios of UE/total orthopaedic emergencies and of H&W/total orthopaedic emergencies increased significantly during the pandemic from 37.17% to 43.32% and from 25.07% to 29.15% (p=0.006 and p<0.001) respectively, compared to 2019. In the private sector, the turnout was increased for patients with UE problems (8.82%, p=0.67) and H&W problems (24.39%, p=0.3), while in the public sector the turnout was significantly decreased for UE (49.77%, p<0.001) and H&W problems (49.92%, p<0.001) in 2020 compared to 2019. DISCUSSION: The extent of lockdown was unprecedented in recent years. The reduction of orthopaedic, UE and H&W emergencies during lockdown can be attributed to the fear of contracting the virus in the hospitals and even more in hospitals serving as COVID-19 reference centers. Despite the decrease -in absolute numbers- of patients, the increased percentages of UE to total orthopaedic and of H&W to total orthopaedic emergencies in 2020 in both hospitals, reflect the new hobbies' uptake and the increase of domestic accidents during the lockdown, despite overall activity decrease, and underline the necessity of presence of hand surgeons in the EDs. This is one of the very few population-based studies worldwide to show trends in incidence of different injuries of the UE at a regional level during the pandemic, and its results could affect future health care policies.
