Affiliation: Emory Sports Medicine Center & Emory University School of Medicine, Atlanta, GA Background: To compare the incidence of re-injury after lower extremity (LE) injury and the days missed following LE injury in high school athletes who use a criteria-based single leg hop test (SLHT) to determine return-to-play (RTP) versus those that do not utilize a criteria-based method. Methods: Prospective cohort analysis of athletic exposures (AE), injuries, re-injuries, and RTP duration between two high schools during the 2017-2018 fall season. One school (SLHT school) utilized the SLHT to determine RTP after LE injuries. The other school (control school) did not utilize a criteria-based method. Athletes were excluded if they sustained a fracture, high-grade ligament tear, or injury requiring surgery. Incidence rates (IR) of LE injuries, re-injuries, and average RTP duration after LE injury were calculated for each school. Results: At the time of submission, there were 66,100 AEs with 41 LE injuries (LE injury IR = 6.2 per 10,000 AEs, 95% CI 4.6-8.4) at the SLHT school and 45,342 AEs with 34 LE injuries (7.7 per 10,000 AEs, 95% CI 5.5-10.8) at the control school (p=0.34). The average RTP duration after LE injury was 12.3 days at the SLHT school and 12.7 days at the control school (p=0.12). There were no re-injuries after LE injury at the SLHT school, and 1 at the control school. Conclusions: There was no statistically significant difference between LE injury rates or RTP duration between the control and intervention schools. There was only 1 re-injury after LE injury that occurred at the control school. Significance: The SLHT does not appear to influence reinjury risk in RTP progression, however it does not add any additional days missed on RTP compared to control school with no criteria-based progression. We will continue to monitor for differences prospectively for another year of exposures.

Desmoplastic small round cell tumor (DSRCT) is a rare but highly fatal malignancy. Due to the rarity of this neoplasm, no large population based studies exist.Procedure. This is a retrospective cohort analysis. Incidence rates were calculated based on sex and ethnicity and compared statistically. Gender-, ethnicity-, and treatment- based survival were calculated using the Kaplan-Meier method.Results. A total of 192 cases of DSRCT were identified. Peak incidence age was between 20 and 24 years. Age-adjusted incidence rate for blacks was 0.5 cases/million and for whites was 0.2 cases/million (P=0.037). There was no statistically significant difference in survival based on gender or ethnicity. When adjusted for age, there was no statistically significant difference in survival amongst patients who received radiation therapy compared to those who did not (HRadj = 0.73; 95% CI 0.49, 1.11). There was a statistically significant survival advantage for patients who received radiation after surgery compared to those who did not (HR 0.49; 95% CI 0.30, 0.79).Conclusion. DSRCT is more common in males and in people of African-American descent. Although overall survival remains poor, radiation therapy following surgery seems to improve outcome in these patients.

Background: The COVID-19 pandemic has led to changes to in-office orthopedic care, with a rapid shift to telemedicine. Institutions’ lack of established infrastructure for these types of visits has posed challenges requiring attention to confidentiality, safety, and patient satisfaction. Purpose: The aim of this study was to analyze the feasibility of telemedicine in orthopedics during the pandemic and its effect on efficiency and patient satisfaction. Methods: Patients seen by the Emory University Department of Orthopaedics Sports Medicine and Upper Extremity Divisions via telemedicine from March 23 to April 24, 2020, were contacted by telephone. Each patient was asked to respond to questions on satisfaction, ease of use, and potential future use; satisfaction with telemedicine and previous clinical visits were measured using a modified 5-point Likert scale. Results: Of the 762 patients seen, 346 (45.4%) completed the telemedicine questionnaire. Satisfaction varied by visit type, with average scores of 4.88/5 for in-office clinic visits versus 4.61/5 for telemedicine visits. There was no significant difference among age groups for satisfaction ratings. Patients 65 years old or older reported significantly longer visit times and decreased ease of use with the telemedicine platform. Conclusion: Telemedicine in a large orthopedics department was successfully implemented without compromising patient satisfaction. The use of telemedicine allows many patients to be seen quickly and efficiently without diminishing their musculoskeletal clinical experience.

Background: The subject of sex-based differences in postoperative recovery after anterior cruciate ligament reconstruction (ACLR) between males and females has been incompletely investigated, with no published comparative analyses specifically in adolescent sub-populations, which represent those most affected by ACL injury. Purpose/Hypothesis: To compare the 6-month postoperative functional recovery following ACLR between adolescent males and females. We hypothesized that significant differences in postoperative strength, dynamic balance, and functional hop test performance would be seen between the sexes. Methods: All adolescent athletes with closed or closing growth plates who underwent ACLR at a single institution between May 2014 and May 2018 and who underwent functional return-to-sport (RTS) testing between 5-8 months post-operatively were considered for inclusion in this IRB-approved study. To control for potential graft-based rehabilitation differences or donor site morbidity as confounders, only primary ACLRs performed with hamstring autograft were included. Exclusions were previous knee surgery (contralateral or ipsilateral knee), concomitant injury other than meniscus tear, allograft supplementation, and incomplete medical records. Limb Symmetry Indexes (LSI) for strength (quadriceps, hamstrings, hip abductors, hip extensors), dynamic Y-balance (anterior, posterolateral and posteromedial distance), and functional hopping (single hop, triple hop, and cross-over hop for distance, and 6-meter timed hop) were compared between groups. To account for differences in physical characteristics between the sexes, one-way between group multivariate analysis of covariance (MANCOVA) was used, with p = 0.05. Results: Amongst 543 subjects (211 male, 332 female), there was no significant difference in age, BMI, incidence of concomitant meniscal pathology, use of regional anesthesia blocks, or time to functional testing between cohorts. However, height and weight differences were incorporated in the MANCOVA model. Females demonstrated a statistically significant greater deficit in quadriceps strength LSI compared to males (Table 1). Both males and females demonstrated 33% hamstring strength deficits, with no statistically significant sex-based differences in dynamic balance or functional hop testing, though single leg hop deficits were less severe in males, which trended towards significance (-4% vs. -8%, p=0.062). Conclusion: Females demonstrated greater quadriceps strength deficits than males at 6 months post-ACLR with hamstring autograft, which may translate into greater functional hop testing deficits. Severe hamstring strength deficits persist in both males and females at this time point, underscoring the potential importance of mitigating risk of ACL re-tear by delaying return to play until a later time point with more normalized, symmetric, performance-based metrics.

Background: There is limited epidemiologic data on pediatric basketball injuries and the correlation of these injuries with sex-based differences pre- and post-adolescence. Purpose: To describe sex and age-based injury rates associated with common pediatric basketball injuries. Methods: A descriptive epidemiology study was conducted utilizing publicly available injury data from the National Electronic Injury Surveillance System (NEISS) and participation data from the National Sporting Goods Association (NSGA). Data on pediatric basketball injuries from January 2012 – December 2018 in patients ages 7-17 years were extracted and used to calculate national injury incidence rates with 95% confidence intervals. Results: Over 7 years, 9,582 basketball injuries were reported annually in the NEISS in pediatric patients 7-17 years old, which corresponds to an annual national estimate of 294,920 visits. The 5 most common diagnoses were ankle strain/sprain (17.7%), finger strain/sprain and finger fracture (12.1%), concussion/head injury (9.4%), knee strain/sprain (4.5%), and facial laceration (3.3%). There was a notable increase in injury rate in adolescents when compared with childhood ages; 7- to 11-year-old category accounted for 19.1% of estimated injuries (56,242 injuries per year) and the 12- to 17-year-old category accounted for 80.9% (238,678 injuries per year). While boys accounted for the majority of injuries in both age groups [72.6% of all injuries (40,824 injuries per year) in the 7- to 11-year-old category and 74.4% of all injuries (177,572 injuries per year) in the 12- to 17-year-old category], overall, there was no significant difference in injury rate between boys and girls (boys: 91 injuries per 100,000 athlete days, 95% CI = 73-109; girls: 110 injuries per 100,000 athlete days, 95% CI = 92-128; p=0.140). Overall injury rates across the two age groups are reported in Table 1. Head injuries/concussions were a frequent cause of presentation (second only to finger injuries) in 7- to 11-year-olds, and occurred at a similar rate in girls and boys. In adolescents, ankle injuries were the most common injury overall, but there was a most notable increase in the rate of girls’ head and knee injury compared with their boy counterparts within these ages (Table 1). Conclusions: Ankle injuries continue to be the most predominant pediatric basketball injury. However, disproportionate rates of girls’ head and knee injuries during adolescent basketball suggest that style of play and knee injury prevention programs should target girls participating in youth basketball.

Background: Sport-related concussion (SRC) is one of the leading injuries among athletes. Previous epidemiological studies have reported incidence rates of concussion among dual gender sports in which both males and females participate including; soccer, basketball, and baseball/softball yet minimal research has been conducted on differences in recovery time following concussion in the dual gender sports mentioned above. Purpose: The purpose of this study was to examine injury reporting trends associated with recovery time from concussion in dual gender sports from 2012-2017. Methods: Athletes with a reported SRC, ages 12 to 18 participating in baseball, softball, basketball, and soccer from 2012 to 2017 were included in the current study. Injury and exposure data was extracted and analyzed from the Rank One Health Injury Surveillance Database (ROH ISD). SRC counts, percentages, and recovery time in days were reported based on extracted data. All demographic and raw data were summarized using descriptive statistics with point estimates and 95% confidence intervals calculated for all end points. Independent sample t-tests were performed at <0.05 to measure significant differences between groups. Results: 1,306 athletes (males=583, females=723) with an SRC and corresponding date of return to play recorded in the ROH ISD and participating in dual gender sports were analyzed. 242 baseball/softball SRCs (male=103, mean recovery days=17.82; female=139, mean recovery days=22.12), 458 basketball SRCs (male=187, mean recovery days=20.16; female=271, mean recovery days=23.29), and 606 soccer SRCs (male=193, mean recovery days=19.96; female=413, mean recovery days=23.71) were included. A statistically significant difference in recovery time was observed in male and female soccer SRCs ( t=2.09, p=0.02). No significant differences were observed in recovery time in baseball/softball ( t=1.59, p=0.057) and basketball ( t=1.49, p=0.068). Conclusions: This is the first study of its kind to examine gender differences in report recovery time from SRCs in dual gender sports where both males and females participate. Significant gender differences were observed in reported recovery time in soccer athletes. Sports specialization, level of play, injury education level among participants, and training regiments could all be potential causes for the observed differences. Further research is warranted to explore these gender differences and identify potential causes for these findings.

Background: Recent literature has shown that between the two sexes, females sustain concussions at a higher rate than males. However, other studies have shown that males take a longer time recover after a concussion than females. Currently, there is limited research done on gender and recovery time in adolescents. Sex is defined as a biological concept that is assigned at birth whereas gender is defined as somebody’s internal self-identification. This study aims to determine if there is a difference in recovery time between genders. Methods: Patients diagnosed with a concussion in our sports medicine clinic were prospectively enrolled into a mild traumatic brain injury (mTBI) repository. 300 patient charts were reviewed. Age, non-binary gender identification, date of injury, first appointment date, and clearance date (Level V) were identified. Post-concussive syndrome (PCS) was also noted. Patients were also recognized if they were lost to follow up. Level of clearance was determined by the 4th International Conference on Concussion in Sports (Zurich 2012) with the following supervised protocol: Level 4: Non-contact training drills, Level 5: Full contact training after medical clearance. Results: 60% (180/300) of patients were cleared for return to play. 57% (171/180) of patients were cleared for a Level V and 5% (9/180) patients were cleared for a Level IV with gradual return to play. 120 (40%) patients were lost to follow up and not cleared, 60% (73/120) identified as male and 40% (47/120) identified as female. For the patients that were cleared, 67% (121/180) of patients identified as male (mean age=13 years) (range 5 to 18 years) and 33% (59/180) of patients identified as female (mean age=14 years) (range 5 to 20 years). From date of injury to recovery time, male patients were cleared on average after 62 days and female patients were cleared on average after 82 days. There was no significant difference between the two genders identified in this specific population (p=0.17). 14% of females and 15% of males were diagnosed with PCS. From date of injury to first appointment with a physician, male and female patients reported going an average 17 days post injury, with no significant difference (p=0.53). Conclusion: Rate of recovery time for patients that sustained a concussion showed no significant difference among genders. Further research is necessary for a comprehensive review of all genders to identify recovery time and appropriate treatment management.

Background: The average professional soccer team experiences 1 to 2 traumatic leg fractures per season, with unknown effects on player performance. Purpose: To (1) determine the rate and time to return to play (RTP) following leg fracture, (2) investigate the rate of reinjury following RTP, and (3) investigate long-term effects that lower extremity (LE) fracture may have on elite soccer player performance. Study Design: Cohort study; Level of evidence, 3. Methods: Using publicly available records, we identified athletes sustaining a traumatic leg fracture across the 5 major European soccer leagues (English Premier League, Bundesliga, La Liga, Ligue 1, and Serie A) between 2000 and 2016. Athletes with leg fracture (femur, tibia, and/or fibula) were matched 1:2 to controls by demographic characteristics and performance metrics 1 season before the index timepoint. Investigations included the RTP rate, reinjury rate, player characteristics associated with RTP within 2 seasons, long-term player retention, performance metrics during the 4 following seasons, and subgroup analysis by player position. Results: A total of 112 players with LE fracture and 224 controls were identified. Players with LE fractures were absent for a mean of 157 days (range, 24-601 days) and 21 games (range, 2-68 games). The rate of RTP within 1 season was 80%, with 4% experiencing subsequent refracture. Injured players remained active in the league at a higher rate than their uninjured counterparts. As compared with controls, injured athletes played 309 fewer total minutes ( P < .05), scored 0.09 more assists per game ( P < .01) 1 season after injury, and scored 0.12 more points per game 4 seasons after injury ( P < .01). Defenders were most affected by an LE fracture, playing 5.24 fewer games ( P < .05), 603 fewer total minutes ( P < .01), and recording 0.19 more assists per 90 minutes of play as compared with controls 1 season after injury ( P < .001). Attackers and midfielders demonstrated no significant difference in metrics after RTP when compared with controls. Conclusion: Most players sustaining an LE fracture returned to elite soccer at the same level after a significant loss of playing time, with a 4% rate of refracture. Player retention was higher for those sustaining an LE fracture versus uninjured controls. Overall, injured players did not experience a decline in performance after recovery from an LE fracture.

Abstract Objectives To investigate the association of calcium supplementation during the pregnancy with the birth weight of single-born neonates. Methods The survey employed a multistage, stratified and random sampling to investigate 15–49 aged pregnant women in 2010 to 2013 in Shaanxi province. A self - designed questionnaire was utilized. Birth weight between the 10(th) and 90(th) percentile was classified as appropriate for gestational age(AGA) infants. Chi-square test and logistic regression models were conducted to evaluate the association of calcium supplementation with single-born neonatal birth weight. Results A total of 28,490 women was enrolled in this study, 17 349 (60.9%) of participants had calcium supplementation during pregnancy. The incidence rates of small and large gestational age infants were 13.5% and 8.3%, respectively. The study conducted that calcium supplementation had a statistically significant difference in SGA (birth weight percentile &lt;10) (P &lt; 0.01). After adjusting the regression models by confounding factors, we found that calcium supplementation was still protective towards SGA birth, the difference was statistically significant (OR = 0.89, 95% CI: 0.82–0.96, P &lt; 0.05), but there was no significant difference in the birth to LGA (birth weight percentile &lt;10). Conclusions Calcium supplementation during pregnancy reduced the risk of SGA, but was not associated with the birth of LGA. Funding Sources

Background: Athletes in the Women’s National Basketball Association (WNBA) and National Basketball Association (NBA) are subject to high injury rates given the physical demands of the sport. Comprehensive data regarding injury patterns and rates in these athletes are limited. Purpose: To summarize available data on orthopaedic and sports medicine–related injuries through 2020 in professional female and male basketball players. Study Design: Systematic review; Level of evidence, 4. Methods: A search was conducted using PubMed and Embase through April 5, 2020, to identify injury studies regarding WNBA and NBA players. Studies were included if the injury or surgery was considered a direct consequence of game play including musculoskeletal/orthopaedic, concussion, ophthalmologic, and craniomaxillofacial injuries. Systematic reviews, screening studies, or studies without sufficient WNBA or NBA player subgroup analysis were excluded. Results: A total of 49 studies met inclusion criteria, 43 (87.8%) of which detailed musculoskeletal injuries. The lower extremity represented 63.3% of studies. A majority (59.2%) of studies were level 4 evidence. The source of data was primarily comprehensive online search (n = 33; 67.3%), followed by official databases (n = 11; 22.4%). Only 3 studies concerned WNBA athletes compared with 47 that concerned NBA athletes. The lowest return-to-play rates were cited for Achilles tendon repairs (61.0%-79.5%). Variability in return-to-play rates existed among studies even with similar seasons studied. Conclusion: The majority of literature available on orthopaedic and sports medicine–related injuries of NBA and WNBA athletes is on the lower extremity. The injuries that had the greatest effect on return to play and performance were Achilles tendon ruptures and knee cartilage injuries treated using microfracture. The reported outcomes are limited by heterogeneity and overlapping injury studies. There are limited available data on WNBA injuries specifically.
