WHAT'S KNOWN ON THIS SUBJECT: Shoulder injuries are common among high school athletes. These injuries, both traumatic and overuse, contribute to significant time loss from athletic activity. Understanding sport-specific injury patterns is critical for development of targeted injury prevention programs.
WHAT THIS STUDY ADDS:This study is the most comprehensive analysis of high school shoulder injuries to date, providing national injury estimates while examining injury rates, diagnoses, severity, and mechanisms of injury in 9 interscholastic sports. abstract OBJECTIVES: The objective of this study was to describe shoulder injuries in a nationally representative sample of high school athletes playing 9 sports. A national estimate of shoulder injuries among high school athletes was subsequently calculated.METHODS: Injury data were collected in 9 sports (boys' football, soccer, basketball, wrestling, and baseball; girls ' soccer, volleyball, basketball, and softball) high school athletes in this study sustained 2798 shoulder injuries during 13 002 321 athlete exposures, for an injury rate of 2.15 per 10 000 athlete exposures. This corresponds to a nationally estimated 820 691 injuries during this time period. Rates of injury were higher in competition as compared with practice (rate ratio = 3.17 [95% confidence interval: 2.94-3.41]). The highest rate of injury was in football (4.86) and the lowest in girls' soccer (0.42). The most common types of injury were strain/sprain (37.9%) and dislocation/separation (29.2%). Boys were more likely than girls to sustain their injuries after contact with another person or with the playing surface. Surgical repair was required for 7.9% of the injuries. Time loss from athletic participation varied among sports, with 40.7% of athletes returning within 1 week, whereas 8.2% were medically disqualified for their season/career.
CONCLUSIONS:High school shoulder injury rates and patterns varied by sport and gender. Prospective epidemiologic surveillance is warranted to discern trends and patterns to develop evidence-based interventions to prevent shoulder injuries. Pediatrics 2014;133:272-279
