Avulsion of the rectus femoris origin is a rare injury. The only previous report of this injury in professional American football has been limited to the kicking athlete.
To describe the incidence and treatment of proximal rectus femoris avulsion in the National Football League (NFL).
Case series; Level of evidence, 4.
The NFL Injury Surveillance System (NFLISS) was reviewed for any proximal rectus femoris avulsion injuries from 1986 to 2006, including the type and mechanism of injury, player demographics, method of treatment, and time to return to play. The NFL team physicians and trainers were surveyed as to their experience with these injuries as well.
A total of 11 cases of proximal rectus femoris avulsion were identified starting in 1997. These injuries occurred in athletes in a variety of positions. All of these were treated nonoperatively, and the mean return to play was 69.2 days.
Rectus femoris avulsions are uncommon injuries in the NFL, occurring about once a year in the entire league (once magnetic resonance imaging facilitated correct diagnosis of these injuries). Conservative treatment of these injuries usually results in return to play after 6 to 12 weeks.
Proximal avulsions of the rectus femoris can be treated nonoperatively with a high degree of predictability for return to full, unrestricted participation in professional American football.
股直肌起点撕脱是一种罕见的损伤。此前关于美国职业橄榄球运动中这种损伤的唯一报告仅限于踢球的运动员。
描述美国国家橄榄球联盟（NFL）近端股直肌撕脱的发生率及治疗情况。
病例系列；证据等级，4级。
回顾1986年至2006年NFL损伤监测系统（NFLISS）中所有近端股直肌撕脱损伤情况，包括损伤类型和机制、运动员人口统计学资料、治疗方法以及重返赛场时间。同时也对NFL球队医生和训练师关于这些损伤的经验进行了调查。
从1997年开始共确定了11例近端股直肌撕脱病例。这些损伤发生在不同位置的运动员身上。所有病例均采用非手术治疗，平均重返赛场时间为69.2天。
股直肌撕脱在NFL中是不常见的损伤，在整个联盟中大约每年发生一次（自从磁共振成像有助于对这些损伤进行正确诊断后）。这些损伤采用保守治疗通常在6至12周后可重返赛场。
近端股直肌撕脱采用非手术治疗，对于完全、无限制地重返美国职业橄榄球运动具有高度可预测性。
