Osteochondral lesion of the talus (OCLT) is frequently described as an uncommon diagnosis; however, little is known of its incidence. In light of increased awareness combined with the continued evolution of radiologic and treatment modalities, more attention has been given to this diagnosis. Serving a young, athletic population with unique occupational requirements, we have perceived an increase in the diagnosis of OCLTs. The goal of this study was to determine the incidence of OCLTs in an active duty military population, as well as demographic risk factors for OCLTs.
We performed a query of the Defense Medical Epidemiology Database (DMED) of the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) code for OCLTs which in the Armed Forces Health Longitudinal Technology Application (AHLTA) system is uniquely assigned the code 732.5. An overall injury incidence was calculated, in addition to multivariate analysis to determine independent risk factors among the following demographic considerations: gender, race, rank, branch of military service, and age. Year of diagnosis was also considered.
The overall incidence rate for the 10-year period (1999 to 2008) was 27 OCLTs per 100,000 person-years. Significant demographic risk factors were female gender, white race, enlisted rank, service in the Army and Marines, and age greater than 20 years. Incidence rate was 16 per 100,000 in 2002, with steady annual increases resulting in an incidence rate of 56 per 100,000 person-years in 2008, corresponding to the years of active involvement in global combat operations.
The incidence of OCLTs in the active duty military population was higher with female gender, white race, enlisted rank, increased age, and Army or Marine service.
距骨骨软骨损伤（OCLT）通常被描述为一种罕见的诊断；然而，其发病率知之甚少。鉴于人们对这种疾病的认识不断提高，加上放射学和治疗方式的不断发展，人们对这种诊断给予了更多的关注。我们的患者群体是年轻的运动员，他们具有独特的职业需求，因此我们发现 OCLT 的诊断数量有所增加。本研究的目的是确定现役军人中 OCLT 的发病率，以及 OCLT 的发病的人口统计学危险因素。
我们对国际疾病分类，第九修订版，临床修正（ICD-9-CM）代码为 OCLT 的国防医疗流行病学数据库（DMED）进行了查询，在 AHLTA 系统中，OCLT 唯一分配的代码是 732.5。除了多元分析以确定以下人口统计学因素中的独立危险因素外，我们还计算了总体损伤发生率：性别、种族、军衔、军种和年龄。还考虑了诊断年份。
在 10 年期间（1999 年至 2008 年），总体发病率为每 100000 人年 27 例 OCLT。性别、种族、军衔、陆军和海军陆战队服役、年龄大于 20 岁是显著的人口统计学危险因素。2002 年的发病率为每 100000 人 16 例，随后每年稳步上升，导致 2008 年的发病率达到每 100000 人年 56 例，这与参与全球作战行动的年份相对应。
在现役军人中，女性、白种人、现役军人、年龄较大、陆军或海军陆战队服役的 OCLT 发病率较高。
