Background: Impaired neuromuscular function after concussion has recently been linked to increased risk of lower extremity injuries in athletes. Purpose: To determine if National Football League (NFL) athletes have an increased risk of sustaining an acute, noncontact lower extremity injury in the 90-day period after return to play (RTP) and whether on-field performance differs pre- and postconcussion. Study Design: Cohort study, Level of evidence, 3. Methods: NFL concussions in offensive players from the 2012-2013 to the 2016-2017 seasons were studied. Age, position, injury location/type, RTP, and athlete factors were noted. A 90-day RTP postconcussive period was analyzed for lower extremity injuries. Concussion and injury data were obtained from publicly available sources. Nonconcussed, offensive skill position NFL athletes from the same period were used as a control cohort, with the 2014 season as the reference season. Power rating performance metrics were calculated for ±1, ±2, and ±3 seasons pre- and postconcussion. Conditional logistic regression was used to determine associations between concussion and lower extremity injury as well as the relationship of concussions to on-field performance. Results: In total, 116 concussions were recorded in 108 NFL athletes during the study period. There was no statistically significant difference in the incidence of an acute, noncontact lower extremity injury between concussed and control athletes (8.5% vs 12.8%; P = .143), which correlates with an odds ratio of 0.573 (95% CI, 0.270-1.217). Days (66.4 ± 81.9 days vs 45.1 ± 69.2 days; P = .423) and games missed (3.67 ± 3.0 vs 2.9 ± 2.7 games; P = .470) were similar in concussed athletes and control athletes after a lower extremity injury. No significant changes in power ratings were noted in concussed athletes in the acute period (±1 season to injury) when comparing pre- and postconcussion. Conclusion: Concussed, NFL offensive athletes did not demonstrate increased odds of acute, noncontact, lower extremity injury in a 90-day RTP period when compared with nonconcussed controls. Immediate on-field performance of skill position players did not appear to be affected by concussion.

Aim: This study aims at determining the upper and lower extremity injury pattern and severity of motorcycle accidents in the Tamale metropolis, Ghana. Methods: A retrospective hospital-based study comprising data on 190 motorcycle accident victims at the Accident and Emergency Centres of three major hospitals (Tamale Teaching Hospital, Central and West Hospitals) in Tamale metropolis from February to April 2018. Demographic data, injury type, injury location, use of crash helmet and injury outcomes were retrieved from the medical records registry. Data was analysed using SPSS version 23.0. Categorical variables were compared using Chi-square test and One-way ANOVA test was done to compare groups. Results: From the 190 victims, 78.9% were treated and discharged, 17.4% were disabled and 3.7% died. Injury mechanism was significantly (F-test = 22.64, p = 0.00) linked with injury outcome. Victims who had frontal impact collision and died (71.4%) were significantly (p<0.05) more than those who were treated and discharged (26.7%). Accident victims with upper extremity injury who became disabled (18.2%) were more (p<0.05) than those treated and discharged (16.7%). Out of the 190 victims involved in motorcycle accidents, 64.2% were not wearing crash helmet. There was significant relationship (p<0.05) between use of crash helmet and injury outcome. More (23.0%) of accident victims disabled were not wearing crash helmet and among those who died, none (0.0%) had a crash helmet on. Conclusion: Upper and lower extremity injuries as well head and neck injuries were high among motorcycle accident victims. The study recommends capacity building for healthcare professionals to manage head, neck, upper and lower extremity injuries at the Accident and Emergency Centres. Regular training programs should be conducted by law enforcement authorities in northern Ghana to train motorcycle riders and educate them on road traffic regulations. Compliance to the use of crash helmet by motorcyclists should strongly be enforced. Further prospective studies are needed to delineate these injury patterns and ascertain reason behind non-usage of crash helmet by motorcyclist in the Metropolis.

Background: Early identification of the BMI and muscle weakness, can be promoted for developing future rehabilitation by giving proper training in athletes to reduce chance of injuries especially in female athletes. There-for the purpose of this study was to determine the correlation between BMI and hip muscle strength in young female athletes. Materials and Methods: study was conducted among college level female athletes from different colleges of Mangalore, Karnataka, India. 20 college level female athletes between 18-25 years with free from injury and involved at least 2 hrs. per week training session were included in this study. Athletes were excluded if participant had an acute injury during previous six months, had musculoskeletal surgery within the past year. Results: The total number of 20 young female athletes aged between 18- 25 were included in this study. Detailed results enumerated in detail in the results section. Discussion and Conclusion: There was no relationship between BMI and hip muscle strength. Identifying the relationship between BMI and hip muscle strength may help to prevent lower extremity injury risk in female athletes and specific muscle group training can be given as rehabilitation protocol. KEY WORDS: BMI, Hip Muscle Strength, Female Athletes, Lower Extremity Injury.

Abstract Background: Injury becomes life threatening community health problem associated with significant mortality and morbidity worldwide. Road traffic accident is the most commonly encountered trauma and the leading cause of death and disability from injuries in Ethiopia. The aim of this study is to assess the epidemiology and outcomes of injury in Ethiopian University Hospital. Methods: Institutional based retrospective cross-sectional study was conducted from January 2015 to June 2019. Data was collected using questionnaire adapted from WHO injury surveillance guideline. Bivariate and multivariate logistic regressions were performed to determine factors associated with hospital mortality. Results: A total of 376 trauma cases were included in the study. The majority of 196(52.1%) victims were in the age range of 20-40 years. Road traffic accident was the commonest mechanism of injury 178(47.3%) followed by interpersonal violence 113(30.1%). The majority of patients 135(35.9%) had associated with lower extremity injury and there was 23(6%) mortality in this study. Revised trauma score (RTS) < 10 (AOR=2.5; 95% CI, 1.8-25.6), Glasgow coma scale (GCS) (AOR =0.3; 95% CI, 0.13-0.5), Length of hospitalization (LOS) 1-7 days (AOR=0.1; 95% CI, 0.01-0.8), and Time to arrival >24hr were predictors of mortality in a patient with injury. Conclusion: A lower extremity injury was common and mostly associated with RTA. Length of hospitalization > 7 days, RTS<10, decrease GCS and time to arrival >24hr were factors associated with mortality. Pre-hospital emergency medical service system and trauma registry needs to be established to decrease burden of injury. Keywords: Injury, Epidemiology, Outcome, Ethiopia
