Describe ankle injury epidemiology among US high school athletes in 20 sports.
Descriptive prospective epidemiology study.
Sports injury data for the 2005/06–2010/11 academic years were collected using an internet-based injury surveillance system, Reporting Information Online (RIO).
A nationwide convenience sample of US high schools.
Assessment of Risk Factors
Injuries sustained as a function of sport and gender.
Main Outcome Measures
Ankle sprain rates and patterns, outcomes, and mechanisms.
From 2005/06–2010/11, certified athletic trainers reported 5,373 ankle sprains in 17,172,376 athlete exposures [AEs], for a rate of 3.13 ankle sprains per 10,000 AEs. Rates were higher for girls than boys (RR 1.25, 95% CI 1.17–1.34) in gender-comparable sports and higher in competition than practice for boys (RR 3.42, 95% CI 3.20–3.66) and girls (RR 2.71, 95% CI 2.48–2.95). The anterior talofibular ligament was most commonly injured (involved in 85.3% of sprains). Overall, 49.7% of sprains resulted in loss of participation from 1–6 days. While 0.5% of all ankle sprains required surgery, 6.6% of those involving the deltoid ligament required surgery. Athletes were wearing ankle braces in 10.6% of all sprains. The most common injury mechanism was contact with another person (42.4% of all ankle sprains).
Ankle sprains are a serious problem in high school sports, with high rates of recurrent injury and loss of participation from sport.
