Context: Surveillance data regarding injuries caused by ball contact in collegiate athletes have not been well examined and are mostly limited to discussions of concussions and catastrophic injuries. Objective: To describe the epidemiology of ball-contact injuries in 11 National Collegiate Athletic Association (NCAA) sports during the 2009–2010 through 2014–2015 academic years. Design: Descriptive epidemiology study. Setting: Convenience sample of NCAA programs in 11 sports (men's football, women's field hockey, women's volleyball, men's baseball, women's softball, men's and women's basketball, men's and women's lacrosse, and men's and women's soccer) during the 2009–2010 through 2014–2015 academic years. Patients or Other Participants: Collegiate student-athletes participating in 11 sports. Main Outcome Measure(s): Ball-contact–injury rates, proportions, rate ratios, and proportion ratios with 95% confidence intervals were based on data from the NCAA Injury Surveillance Program during the 2009–2010 through 2014–2015 academic years. Results: During the 2009–2010 through 2014–2015 academic years, 1123 ball-contact injuries were reported, for an overall rate of 3.54/10 000 AEs. The sports with the highest rates were women's softball (8.82/10 000 AEs), women's field hockey (7.71/10 000 AEs), and men's baseball (7.20/10 000 AEs). Most ball-contact injuries were to the hand/wrist (32.7%) and head/face (27.0%) and were diagnosed as contusions (30.5%), sprains (23.1%), and concussions (16.1%). Among sex-comparable sports (ie, baseball/softball, basketball, and soccer), women had a larger proportion of ball-contact injuries diagnosed as concussions than men (injury proportion ratio = 2.33; 95% confidence interval = 1.63, 3.33). More than half (51.0%) of ball-contact injuries were non-time loss (ie, participation-restriction time <24 hours), and 6.6% were severe (ie, participation-restriction time ≥21 days). The most common severe ball-contact injuries were concussions (n = 18) and finger fractures (n = 10). Conclusion: Ball-contact–injury rates were the highest in women's softball, women's field hockey, and men's baseball. Although more than half were non–time-loss injuries, severe injuries such as concussions and fractures were reported.

Background. Article investigates youngster physical activity (PA) habits, finding tendencies of PA participation, factors promoting and impeding it. Methods. The methods include literature analysis, cross-sectional study with self-reported questionnaire consisting of 11 questions and statements about most popular leisure sports, frequency, venues, significant others, and neighbourhood influence. The questionnaire, based on EU Special Eurobarometer 412 “Sport and Physical Activity”, research in Northern and Eastern countries, as well as in the Netherlands, was sent by e-mail to 91 Grade 10 subjects in a Latvian mainstream secondary school in the academic year of 2015/2016; the response rate was 60%. The statistical analysis was carried out with Index method and SPSS software. Results. The Cronbach’s alpha for neighbourhood section (5 items) of the questionnaire was .74. The validity of the questionnaire was based on the consideration that the questions were drawn from surveys, described in reliable sources. Most of the students with friends or alone did three sports at sport schools (69.50%), as well as in parks, woods, seaside, at home, most popular sports were team games (basketball, volleyball), winter sports (skiing and snowboarding), fitness sports (running), strength sports (gym workout) and gymnastics. Statistically significant, medium strong correlations were found between good relations with neighbours and high level of well-being (r = .38, p = .05). Conclusion. The student choice to practice team games and gymnastics might be influenced by traditional youngster values and their status as trendy sports, but winter sports in Latvia traditionally are among the most popular ones. Good neighbourhood relations could help youngsters be more physically active.

ObjectiveQuantify income-based inequalities in self-reported moderate-to-vigorous physical activity (MVPA) in England and the USA by sex.DesignPopulation-based cross-sectional study.Participants4019 adolescents aged 11–15 years in England (Health Survey for England 2008, 2012, 2015) and 4312 aged 12–17 years in the US (National Health and Nutrition Examination Survey 2007–2016).Main outcome measuresThree aspects of MVPA: (1) doing any, (2) average min/day (MVPA: including those who did none) and (3) average min/day conditional on participation (MVPA active). Using hurdle models, inequalities were quantified using the absolute difference in marginal means (average marginal effects).ResultsIn England, adolescents in high-income households were more likely than those in low-income households to have done any formal sports/exercise in the last 7 days (boys: 11%; 95% CI 4% to 17%; girls: 13%; 95% CI 6% to 20%); girls in high-income households did more than their low-income counterparts (MVPA: 6 min/day, 95% CI 2 to 9). Girls in low-income households spent more time in informal activities than girls in high-income households (MVPA: 21 min/day; 95% CI 10 to 33), while boys in low-income versus high-income households spent longer in active travel (MVPA: 21 min/week; 95% CI 8 to 34). In the USA, in a typical week, recreational activity was greater among high-income versus low-income households (boys: 15 min/day; 95% CI 6 to 24; girls: 19 min/day; 95% CI 12 to 27). In contrast, adolescents in low-income versus high-income households were more likely to travel actively (boys: 11%; 95% CI 3% to 19%; girls: 10%; 95% CI 3% to 17%) and do more.ConclusionsPolicy actions and interventions are required to increase MVPA across all income groups in England and the USA. Differences in formal sports/exercise (England) and recreational (USA) activities suggest that additional efforts are required to reduce inequalities.

Category: Ankle Introduction/Purpose: Osteochondral lesion of talus (OLT) is treated by several procedures such as bone marrow stimulation technique, cartilage fragment fixation, or autologous osteochondoral bone implantation. The choice of surgical methods depends on the size of lesion and cartilage condition. For unstable small lesion, excision of osteochondral fragment is usually performed. Good clinical results after this procedure is reported, but it is unclear that the morphological repair of subchondral bone and cartilage like tissue at the lesion. The purpose of this study is to evaluate the restoration of subchondral bone and cartilage like tissue after arthroscopic microfracture with excision of osteochondral fragment, and to investigate the clinical outcomes of this operation for the athletes. Methods: From 2005 to 2015, 11 patients (6 men and 5 women) were performed arthroscopic microfracture with excision of osteochondral fragment for OLT. Average age was 28.6 years old (17 - 59 years old). The site of OLT was 10 medial and 1 lateral. The cases of athletes were 7 of 11 cases. The size of preoperative OLT by MRI, measure the depth of the resected site on 3-month postoperative MRI. And we evaluated the appearance of the repair site on 1 year postoperative MRI, clinical outcome using American Orthopaedic Foot and Ankle Society Clinical Rating System (AOFAS), return rate to sports, and period of return to the sports. Results: Preoperative size of lesion on MRI was 9.8 mm in sagittal view, and 6.0 mm in coronal view. Depth of the resected site in 3 months postoperative MRI was 3.1 mm. On one year postoperative MRI, the resected site was filled with cartilage like tissue, and the shape of restored site was good that mimicked the original shape (Figure 1). As for clinical outcome, AOFAS score was 65.4 points preoperatively, and it improved to 93.4 points 1 year postoperatively. In clinical outcomes of the athletes, all cases could return to sports. Average period to return sports was 5.6 months. Only in 1 case, mild pain during sports activity was remained. Preoperative AOFAS score of athletes was 71.4 points and it improved to 98.5 points postoperatively. Conclusion: According to this study, even if a symptom is mild, an early operation will be more likely to result in the early return to sports and good outcomes. In addition, these good outcomes and good congruency on 1 year postoperative MRI suggest that the restored cartilage like tissue is enough for the high activities. The cartilage is repaired with maintaining original shape of talus cartilage. And this method was effective for athletes and was able to get them return to sports with good outcome.

Background: Although eye injuries constitute a small percentage of high school and college sports injuries, they have the potential to be permanently debilitating. Hypothesis: Eye injury rates will vary by sport, sex, and between the high school and college age groups. Study Design: Descriptive epidemiology study. Level of Evidence: Level 3. Methods: Data from eye injury reports in high school and college athletes were obtained from the National High School Sports-Related Injury Surveillance System, High School Reporting Information Online (HS RIO) database over a 10-year span (2005-2006 through 2014-2015 school years) and the National Collegiate Athletic Association (NCAA) Injury Surveillance Program (ISP) over an 11-year span (2004-2005 through 2014-2015 school years). Injury rates per 100,000 athlete-exposures (AEs), injury rate ratios (RRs), and 95% CIs were calculated. Distributions of eye injuries by diagnosis, mechanism, time loss, and surgery needs were also examined. Results: A total of 237 and 273 eye injuries were reported in the HS RIO and the NCAA ISP databases, respectively. The sports with the highest eye injury rates (per 100,000 AEs) for combined high school and college athletes were women’s basketball (2.36), women’s field hockey (2.35), men’s basketball (2.31), and men’s wrestling (2.07). Overall eye injury rates at the high school and college levels were 0.68 and 1.84 per 100,000 AEs, respectively. Eye injury rates were higher in competition than practice in high school (RR, 3.47; 95% CI, 2.69-4.48) and college (RR, 3.13; 95% CI, 2.45-3.99). Most injuries were contusions (high school, 35.9%; college, 33.3%) and due to contact (high school, 89.9%; college, 86.4%). Only a small percentage of injuries resulted in time loss over 21 days (high school, 4.2%; college, 3.0%). Conclusion: Eye injury rates and patterns vary by sport, sex, and between the high school and college age groups. Although severe injuries do occur, most eye injuries sustained by high school and college athletes are minor, with limited time loss and full recovery. Clinical Relevance: Additional focus needs to be placed on preventing eye injuries at the collegiate level in women’s and men’s basketball, women’s field hockey, and men’s wrestling.

Abstract Purpose Among juvenile apophyseal avulsion injuries of the pelvis in adolescents, fractures of the ischial tuberosity are rare but sustainably debilitating. Also because informations on surgical repair options are very sparse and so far limited to general reviews, reports of individual cases or heterogeous small case series, practitioners, patients and their parental environment still feel a comprehensible hesitation regarding operative treatment. Therefore we intended to investigate patient related outcome measurements and return to sports rates after different types of surgical intervention in an own case series, so far unprecendented in its size. Methods Patient data of adolescents that underwent surgical intervention for a displaced apophyseal avulsion fracture of the ischial tuberosity between 01/2015 and 12/2019 in our institution were gathered. Patients were then evaluated using the hamstring injury specific Perth Hamstring Assessment Tool (PHAT). Furthermore the return to sports level in comparison to the particular pre-injury level was rated. Results Eleven adolescents with an acute or chronic mean fragment dislocation of 3.3 cm (SD ± 1.7) underwent surgical intervention in the assigned period. The mean post-operative PHAT score was 86.9 (0–100, SD ± 11.9) and thus good to excellent. The majority of adolescents (10/11) was able to return to their pre-injury sports, whereas 63.6% achieved full or nearly full level. Conclusions Surgical refixation or restoration of aphoyseal avulsion fractures of the ischial tuberosity result in good to excellent outcomes and return to sport rates, irrespective of the type of intervention. Here prompt diagnosis with a timely intervention seems more promising than delayed interventions in chronic cases. Beyond 1.5 cm of fragment displacement affected patients should be counselled for surgical intervention.

BackgroundCalcific tendinitis of the rotator cuff is one of the most common causes of shoulder pain. (1) Ultrasound guided percutaneous lavage (UGPL) is indicated when conservative treatments have failed. (2) Recent reports have shown the interest of topical sodium thiosulfate (STS) in the treatment of other diseases characterizes by ectopic calcifications (3, 4, 5).ObjectivesTo assess the efficacy and safety of UGPL with STS versus with saline solution (standard of care - SOC) in calcific tendinitis.MethodsDouble-blinded randomized clinical trial including adult patients with calcific tendinitis, shoulder pain for more than 3 months and at least one positive shoulder impingement test. Only dense type A calcifications (according to the Molé Classification) > 5 mm in diameter were included. Patients were randomized in two groups: STS and saline solution lavage. Informed consents were collected. Both groups were reevaluated at week 1, month 1 and month 3 after UGPL. Pain Visual Analogue Scale (VAS) at rest and during activities, shoulder range of motion and strength, impingement tests, Disabilities of the Arm, Shoulder and Hand (DASH), DASH-Work, EuroQol five-dimensional (EQ5D) and University of California at Los Angeles (UCLA) scores, ultrasound (US) and radiographic evaluations were performed on all follow up visits.SPSS was used for statistical analysis and significance level was defined as 2-sided p<0.05.ResultsTwenty-six patients were included, where 76.9% (20) were women, with a mean age of 51.2 (SD=9.0) years old. The mean duration of pain before the procedure was 12.7 months (SD=11.3) (minimum of 3 months and a maximum of 48 months).Fifteen patients (57.7%) were randomized to the control group (SOC) and performed a saline UGPL; the other 11 patients (42.3%) were randomized to the treatment group (STS). Demographic and baseline clinical characteristics are shown in Table 1. Since patient inclusion is dynamic, our sample met 23 patients at week 1 (SOC group = 13 and STS group = 10), 19 patients at month 1 (SOC group = 10 and STS group = 9) and 16 patients at month 3 (SOC group = 8 and STS group = 8).Table 1.Demographic and baseline clinical characteristics.STS lavage(n=11)Saline solution lavage (n=15)p-valueAge (years), M (SD)52.3 (10.6)50.3 (8.0)NSSex, female % (n/N)72.7% (8/11)80% (12/15)NSDominant side, right % (n/N)100% (11/11)93.3% (14/15)NSNocturnal pain, yes % (n/N)100% (11/11)100% (15/15)NSVAS at rest (0–10), M (SD)5.7 (2.0)5.9 (2.1)NSVAS during activities (0–10), M (SD)7.1 (1.8)6.0 (2.5)NSDASH Score, M (SD)60.2 (14.0)52.6 (13.8)NSDASH-Work Score, M (SD73.4 (11.0)63.4 (22.6)NSEQ5D, M (SD)0.2897 (0.3)0.4070 (0.2)NSVAS EQ5D (0–100), M (SD)54 (15.9)58 (20.0)NSUCLA score, M (SD)18.7 (4.1)14.7 (3.3)0.014Bursitis, yes % (n/N)72.7% (8/11)66.7% (10/15)NSCalcification morphology, % (n/N)Acr-shaped18.2% (2/11)40% (6/15)0.039Fragmented18.2% (2/11)26.7% (4/15)Nodular and dense, well-defined63.6% (7/11)33.3% (5/15)Calcification size, median (IQR)12.6 (5.7)10.5 (6.3)NSSD: Standard deviation; M: Mean; NS: non-significant; IQR: interquartile rangeOverall, there were no differences between control (SOC) and treatment group (STS).

Context Understanding time loss resulting from sport-related concussion (SRC) within individual sports allows high school athletic trainers to provide accurate and evidence-based clinical information. Currently, research regarding patterns of clinical recovery outcomes in high school student-athletes across sports is lacking. Objective To describe the time to authorized unrestricted return to participation (RTP) after SRC in a large cohort of high school student-athletes in a variety of sports using a time-to-event analysis. Design Descriptive epidemiology study. Setting Aggregate injury and player exposure data from the Michigan High School Athletic Association Head Injury Reporting System. Patients or Other Participants High school student-athletes. Main Outcome Measure(s) Dates for SRC injury events and authorized unrestricted RTP were entered into the Head Injury Reporting System for each case and were used to calculate time to unrestricted RTP. Survival analysis indicated the time to authorized RTP for males and females in weekly increments across sports and academic years. Separate Kaplan-Meier analyses adjusted for SRC cases with a history of concussion also identified the proportions of student-athletes who obtained authorized medical clearance in weekly increments. Results A total of 15 821 SRCs, 10 375 (65.6%) in males and 5446 (34.4%) in females, were reported during the 2015–2016 through 2018–2019 academic years. The median time to authorized unrestricted RTP was 11 days for all patients. Approximately 30% of concussed student-athletes were not cleared for unrestricted RTP by 14 days after their SRC diagnosis, with 13% taking longer than 21 days to return to unrestricted RTP after SRC. Conclusions The results from this multisite, state-based injury surveillance system indicated that it is not abnormal for high school student-athletes to take longer than 14 days to fully recover from an SRC. This information may be useful for educating high school student-athletes and sport stakeholders, normalizing SRC recovery trajectory perceptions, and establishing realistic RTP timeline expectations.

Background & Objectives: To evaluate the visual outcomes of children presenting with unilateral traumatic cataract.Materials & Methods: We conducted a retrospective study of 111 children (70 males and 41 females) below 16 years of age who were diagnosed with unilateral traumatic cataract between June 2013 and May 2015 and who underwent surgical intervention and completed at least six months follow up at Paediatrics department (supported by ORBIS International), R. M. Kedia eye hospital, Birganj, Nepal. Data regarding demographic profile, causative agent, clinical course and visual outcomes were recorded.Results: There was a male predilection with a male to female ratio of 1.70:1. The age group more frequently affected was five to nine years (58.5%). Commonest causative agent was trauma with wooden stick in 20 eyes (18%) followed by firecrackers in 15 eyes (14%) and pen in 11 eyes (10%). Pre-existing posterior capsular defects were observed intraoperatively in six eyes. Anterior uveitis was evident in 21 cases and Posterior capsular opacification in 10 eyes. Best corrected visual acuity of 6/6-6/60 at six months was achieved in 91 cases (81%). Duration between injury and cataract surgery did not affect the final visual outcome of traumatic cataract patients.Conclusion: The best possible visual outcome of traumatic cataract depends on its management and its complication. Ocular trauma and traumatic cataract formation can be avoided by taking protective measures in sports, work and patient education.JCMS Nepal. 2016;12(2):40-3

Objectives: Hamstring tears are one of the most common muscular injuries seen in athletes [1]. These injuries are especially prevalent in sports associated with sprinting or jumping, with previous literature indicating that football, soccer, and track athletes are most at risk [1]. Hamstring injuries are classified into strains (Grade I), partial tears (Grades 2) and full thickness tears (Grade 3). Previous literature has described the epidemiology of hamstring strains/tears in NCAA athletes from 2009-2014 [1]. The aim of this study was to describe the epidemiology of hamstring tears in NCAA sports during 2014/15-2018/19. Methods: This study utilized NCAA Injury Surveillance Program (ISP) exposure and injury data submitted by athletic trainers (ATs) at participating institutions (via their respective Electronic Medical Records system) during the 2014/15-2018/19 academic years. Hamstring Tear (Partial or Complete) rates (stratified by sport, event type, and sex) per 10,000 athlete-exposures (AEs) and rate profile plots by event type stratified by sex were constructed. The distribution of injuries by history (new, recurrent) and timeloss (>1 day [TL]; non-timeloss [NTL]) was also examined. Injury Rate Ratios (IRRs) were constructed to evaluate differential injury rates by event type (practice, competition) and sex (male, female [for sex-comparable sports]) and injury proportion ratios (IPRs) were used to evaluate differential proportions by injury history (new, recurrent) and timeloss (TL, NTL); effect estimates with 95% CIs excluding 1.00 were considered statistically significant. Results: Across the study period, 2,096 hamstring tears from 8,474,400 AEs (2.47 per 10,000 AEs) were reported to the NCAA ISP. Amongst men’s sports, overall injury rates were highest in soccer (5.97 per 10,000 AEs), football (4.35 per 10,000 AEs), and track & field (3.57 per 10,000 AEs). In women’s sports, overall injury rates were highest in soccer (3.13 per 10,000 AEs), field hockey (2.09 per 10,000 AEs), and track & field (1.98 per 10,000 AEs). The rate of hamstring tear injuries in men’s/women’s competitions increased between 2014/15 and 2015/16, then decreased across the study period. Whereas the rate of hamstring tear injuries in men’s/women’s practice remained stable across the study period. Recurrent hamstring tears accounted for comparable proportions of all hamstring tears in men’s (14.8%) and women’s (11.5%) sports. A greater proportion of injuries in men’s sports (as compared with women’s sports) resulted in TL (IPR=1.33; 95% CI=1.21, 1.47). Among sex-comparable sports, injury rates were higher in the following men’s sports (as compared with respective women’s sports): baseball (IRR= 1.79; 95% CI=1.31, 2.44) [compared to women’s softball], soccer (IRR= 1.91; 95% CI=1.54, 2.37), and track & field (IRR= 1.80; 95% CI= 1.43, 2.27). Conclusions: Across all NCAA sports, hamstring strain incidence was highest in men’s soccer, men’s football, and men’s track & field. Hamstring tear incidence was higher among men’s baseball, soccer, and track & field compared to women’s comparable sports. Elucidating contributory factors that explain higher hamstring tear incidence in men’s sports (compared to sex-comparable women’s sports) warrants further attention. The development and improvement of hamstring tear injury prevention programs to reduce the burden of this injuries in all NCAA athletes remains critical. In evaluating the temporal patterns in hamstring tear incidence in NCAA sports by event type and stratified by gender, the competition-related injury rate in men’s and women’s sports followed a similar pattern and was lower in 2018/19 compared to 2014/15. A greater proportion of hamstring tears in Men’s sports resulted in time loss of >1 day as compared with hamstring tears in women’s sports. Compared to the previous study period (2009/10-2013/14), a higher proportion of all injuries in the present study were recurrent hamstring tears and a higher proportion of all injuries in this study resulted in time loss of >1 day. [1] In sum, this information can aid sports medicine professionals in identifying athletes who may be at risk for injury and may be valuable in counseling patients with regards to rehabilitative treatment timeline expectations. In order to decrease risk of hamstring tear incidence, sport and athlete specific preventative rehabilitation techniques isolating and targeting the hamstring muscles may be beneficial.
