Glenohumeral instability is a common injury sustained by young athletes. Surprisingly, little is known regarding the incidence of glenohumeral instability in collegiate athletes or the relevant risk factors for injury. A better understanding of the populations most at risk may be used to develop preventive strategies.
The incidence of glenohumeral instability in collegiate athletics is high, and it is affected by sex, sport, type of event, and mechanism of injury.
Descriptive epidemiologic study.
The National Collegiate Athletic Association injury database was queried for all glenohumeral instability events occurring between the years 1989 and 2004. An analysis of the injuries was performed by sport, activity (competition versus practice), sex, type of event (primary versus recurrent), mechanism of injury, and time loss from athletic performance. Incidence rates and incidence rate ratios were calculated.
A total of 4080 glenohumeral instability events were documented for an incidence rate of 0.12 injuries per 1000 athlete exposures. The sport with the greatest injury rate was men's spring football, with 0.40 injuries per 1000 athlete exposures. Overall, athletes sustained more glenohumeral instability events during games than practices (incidence rate ratio [IRR], 3.50; 95% confidence interval [CI], 3.29-3.73). Male athletes sustained more injuries than did female athletes (IRR, 2.67; 95% CI, 2.43-2.93). Female athletes were more likely to sustain an instability event as the result of contact with an object (IRR, 2.43; 95% CI, 2.08-2.84), whereas male athletes were more likely to sustain an event from player contact (IRR, 2.74; 95% CI, 2.31-3.25). Time lost to sport (>10 days) occurred in 45% of glenohumeral instability events.
Glenohumeral instability is a relatively common injury sustained by collegiate athletes. More injuries occurred during competition and among male athletes.
盂肱关节不稳定是年轻运动员常见的损伤。令人惊讶的是，对于大学生运动员盂肱关节不稳定的发生率以及相关的损伤危险因素知之甚少。更好地了解风险最高的人群，可能有助于制定预防策略。
大学生运动员盂肱关节不稳定的发生率较高，受性别、运动、事件类型和损伤机制的影响。
描述性流行病学研究。
查询了 1989 年至 2004 年期间发生的所有盂肱关节不稳定事件的全国大学生体育协会损伤数据库。对运动、活动（比赛与练习）、性别、事件类型（初次与复发性）、损伤机制以及运动员表现的时间损失进行分析。计算发生率和发生率比。
共记录了 4080 例盂肱关节不稳定事件，发生率为每 1000 名运动员暴露 0.12 例。受伤率最高的运动是男子春季足球，每 1000 名运动员暴露 0.40 例。总体而言，运动员在比赛中比在练习中更容易发生盂肱关节不稳定事件（发生率比[IRR]，3.50；95%置信区间[CI]，3.29-3.73）。男性运动员比女性运动员更容易受伤（IRR，2.67；95% CI，2.43-2.93）。女性运动员更有可能因与物体接触而发生不稳定事件（IRR，2.43；95% CI，2.08-2.84），而男性运动员更有可能因球员接触而发生事件（IRR，2.74；95% CI，2.31-3.25）。超过 10 天的运动时间损失（>10 天）发生在 45%的盂肱关节不稳定事件中。
盂肱关节不稳定是大学生运动员常见的损伤。更多的损伤发生在比赛中，且更多的男性运动员受伤。
