BACKGROUND: Ankle sprains are one of the most common injuries in basketball. Despite this, the incidence and setting of ankle sprains among elite basketball players are not well described. PURPOSE: To describe the epidemiology of ankle sprains among National Basketball Association (NBA) players. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: All players on an NBA roster for ≥1 NBA game (preseason, regular season, or playoffs) during the 2013-14 through 2016-17 seasons were included. Data were collected with the NBA electronic medical record system. All NBA teams used the electronic medical record continuously throughout the study period to record comprehensive injury data, including onset, mechanism, setting, type, and time lost. Game incidence rates were calculated per 1000 player-games and per 10,000 player-minutes of participation, stratified by demographic and playing characteristics. RESULTS: There were 796 ankle sprains among 389 players and 2341 unique NBA player-seasons reported in the league from 2013-14 through 2016-17. The overall single-season risk of ankle sprain was 25.8% (95% CI, 23.9%-28.0%). The majority of ankle sprains occurred in games (n = 565, 71.0%) and involved a contact mechanism of injury (n = 567, 71.2%). Most ankle sprains were lateral (n = 638, 80.2%). The incidence of ankle sprain among players with a history of prior ankle sprain in the past year was 1.41 times (95% CI, 1.13-1.74) the incidence of those without a history of ankle sprain in the past year ( = .002). Fifty-six percent of ankle sprains did not result in any NBA games missed (n = 443); among those that did, players missed a median of 2 games (interquartile range, 1-4) resulting in a cumulative total of 1467 missed player-games over the 4-season study period. CONCLUSION: Ankle sprains affect approximately 26% of NBA players on average each season and account for a large number of missed NBA games in aggregate. Younger players and players with a history of ankle sprain have elevated rates of incident ankle sprains in games, highlighting the potential benefit for integrating injury prevention programs into the management of initial sprains. Research on basketball- and ankle-specific injury prevention strategies could provide benefits.
背景：踝关节扭伤是篮球运动中最常见的损伤之一。尽管如此，NBA 球员的踝关节扭伤发生率和发生地点仍未得到很好的描述。 目的：描述 NBA 球员踝关节扭伤的流行病学情况。 研究设计：队列研究；证据水平，3 级。 方法：纳入 2013-14 赛季至 2016-17 赛季期间在 NBA 阵容中至少参加 1 场 NBA 比赛（季前赛、常规赛或季后赛）的所有球员。数据通过 NBA 电子病历系统收集。在整个研究期间，所有 NBA 球队都使用电子病历系统连续记录全面的损伤数据，包括发病时间、机制、发生地点、类型和损失时间。根据人口统计学和比赛特征，以每 1000 名球员比赛和每 10000 名球员分钟的参与率计算比赛发生率。 结果：在 2013-14 赛季至 2016-17 赛季期间，联盟中共有 389 名球员报告了 796 例踝关节扭伤和 2341 例独特的 NBA 球员赛季。单赛季踝关节扭伤的总体风险为 25.8%（95%CI，23.9%-28.0%）。大多数踝关节扭伤发生在比赛中（n=565，71.0%），涉及接触性损伤机制（n=567，71.2%）。大多数踝关节扭伤为外侧（n=638，80.2%）。过去 1 年有踝关节扭伤病史的球员的踝关节扭伤发生率是过去 1 年无踝关节扭伤病史的球员的 1.41 倍（95%CI，1.13-1.74）（=0.002）。56%的踝关节扭伤不会导致任何 NBA 比赛的缺席（n=443）；在那些导致比赛缺席的踝关节扭伤中，球员平均缺席 2 场比赛（四分位间距，1-4），导致在 4 个赛季的研究期间总共缺席 1467 场 NBA 比赛。 结论：踝关节扭伤平均影响每个赛季约 26%的 NBA 球员，并且在总体上导致大量 NBA 比赛的缺席。年轻球员和有踝关节扭伤病史的球员在比赛中的踝关节扭伤发生率较高，这突出了将损伤预防计划纳入初始扭伤管理的潜在益处。关于篮球和踝关节特定损伤预防策略的研究可能会带来益处。
