Little is known of the incidence of shoulder instability, despite some evidence that it may be a common injury in young, athletic individuals. The goal of this study was to determine the incidence of shoulder dislocation in United States military personnel, as well as to identify the demographic risk factors for injury.
We performed a query of the Defense Medical Epidemiology Database with the code from the International Classification of Diseases, Ninth Revision, for acute shoulder dislocation for the years 1998 through 2006. An overall injury incidence was calculated, in addition to multivariate analysis, to determine independent risk factors among the following demographic considerations: sex, race, branch of military service, rank, and age.
The overall incidence rate was 1.69 dislocations per 1000 person-years. Significant demographic risk factors were male sex, white race, service in the Army, junior enlisted rank, and an age of less than thirty years (p<0.0001).
The incidence of shoulder instability among U.S. military personnel (1.69 per 1000 person-years) is considerably higher than previous reports for the general U.S. population (0.08 per 1000 person-years). Male sex, white race, and an age of less than thirty years were significant independent risk factors for injury.
尽管有证据表明肩部不稳定可能是年轻运动员常见的损伤，但目前对其发病率知之甚少。本研究的目的是确定美国军事人员肩部脱位的发病率，并确定受伤的人口统计学风险因素。
我们使用国际疾病分类第九版的代码，对1998年至2006年期间国防医疗流行病学数据库中急性肩部脱位的情况进行了查询。除了多变量分析外，还计算了总体损伤发病率，以确定以下人口统计学因素中的独立风险因素：性别、种族、军种、军衔和年龄。
总体发病率为每1000人年1.69例脱位。显著的人口统计学风险因素为男性、白人、陆军服役、初级入伍军衔以及年龄小于30岁（p<0.0001）。
美国军事人员肩部不稳定的发病率（每1000人年1.69例）远高于此前美国普通人群的报告发病率（每1000人年0.08例）。男性、白人以及年龄小于30岁是受伤的显著独立风险因素。
