To describe the prevalence, severity, and location of ankle injuries as assessed on magnetic resonance imaging (MRI) in athletes participating in the Rio de Janeiro 2016 Summer Olympic Games.
We analyzed all ankle MRIs that were acquired for suspected injury as reported by the National Olympic Committee medical teams and the Organizing Committee medical staff during the Rio 2016 Summer Olympics. Diagnostic imaging was performed through the Olympic Village Polyclinic. Images were interpreted retrospectively according to standardized criteria.
A total of 11,274 athletes participated in the Games, of which 89 (8.8%) were referred for an ankle MRI. Eighty-eight of the 89 (99%) had at least 1 abnormal finding, and some had as many as 27, for an average of 6.2 abnormalities per examination. Around one-fifth of all abnormal findings were considered pre-existing (21%) and 79% were assumed to be the result of an acute or subacute injury. The highest proportion of acute/subacute injuries per athlete occurred in ball sports (7.0 injuries per examination) and in the age group >30. Most pre-existing findings per athlete were identified in the group of others (no track and field or ball sports athletes) with 2.5 findings per examination and respectively in the age group >30 (1.7).
Our study demonstrated a high prevalence of acute and subacute, but also pre-existing injuries in Olympic athletes undergoing ankle MRI. Tendon injuries were the most common acute injuries, found mainly in ball sports athletes. Most pre-existing ankle injuries were identified at the ligaments.
描述参加 2016 年里约热内卢夏季奥运会的运动员在磁共振成像（MRI）上评估的踝关节损伤的患病率、严重程度和位置。
我们分析了所有由国家奥林匹克委员会医疗团队和组织委员会医务人员报告的疑似损伤的踝关节 MRI，这些 MRI 是在 2016 年里约夏季奥运会期间获取的。诊断性成像通过奥运村综合诊所进行。根据标准化标准对图像进行回顾性解释。
共有 11274 名运动员参加了比赛，其中 89 名（8.8%）因踝关节 MRI 而被转诊。89 名患者中有 88 名（99%）至少有 1 处异常发现，有些患者多达 27 处，平均每次检查有 6.2 处异常。所有异常发现中有近五分之一被认为是预先存在的（21%），79%被认为是急性或亚急性损伤的结果。每运动员发生的急性/亚急性损伤中，比例最高的是球类运动（每检查 7.0 处损伤）和年龄>30 岁的运动员。每运动员的预先存在的发现中，比例最高的是在其他组（没有田径或球类运动员）中，每检查有 2.5 处发现，分别在年龄>30 岁（1.7）的运动员中。
我们的研究表明，接受踝关节 MRI 的奥林匹克运动员中存在较高的急性和亚急性，也有预先存在的损伤。跟腱损伤是最常见的急性损伤，主要发生在球类运动运动员中。大多数预先存在的踝关节损伤发生在韧带处。
