Elite American football athletes are at high risk for Jones fractures. Fixation is recommended to minimize nonunion and allow early return to play. The purpose of this investigation was to evaluate the prevalence of Jones fracture repair in athletes invited to the National Football League (NFL) Combine and the impact of fracture repair on short-term NFL participation compared to athletes with no history of repair.
A total of 1311 athletes participating in the Combine from 2012 to 2015 were evaluated. Athletes with history of Jones fracture repair were identified. Athlete demographic information was collected while physical examination findings were recorded. Radiographs were evaluated to determine fixation type and the presence of nonunion. Future participation in the NFL was evaluated based on draft status, games played, and games started in the athlete's first season following the Combine.
Fixation was performed for 41 Jones fractures in 40 athletes (3.1%). The highest prevalence was in defensive linemen (n = 10 athletes), with the greatest rate in tight ends (5.1%, n = 4 of 79 athletes). Intramedullary screw fixation was used for all fractures. Incomplete bony union was present in 3 (8%) fractures. Athletes with a history of repair were not at significant risk for going undrafted ( P = .61), playing ( P = .23), or starting ( P = .76) fewer NFL games compared to athletes with no history of repair during athletes' first NFL season.
Athletes with a history of Jones fracture repair were not at significant risk of going undrafted or for diminished participation during their first season in the NFL.

美国精英橄榄球运动员发生琼斯骨折的风险很高。建议进行固定以尽量减少骨不连，并允许早日重返赛场。本研究的目的是评估受邀参加美国国家橄榄球联盟（NFL）联合试训的运动员中琼斯骨折修复的发生率，以及与无骨折修复史的运动员相比，骨折修复对NFL短期参赛情况的影响。
对2012年至2015年参加联合试训的1311名运动员进行了评估。确定有琼斯骨折修复史的运动员。收集运动员的人口统计学信息并记录体格检查结果。评估X线片以确定固定类型和骨不连情况。根据运动员在联合试训后的第一个赛季的选秀状态、参赛场次和首发场次来评估其未来在NFL的参赛情况。
40名运动员的41处琼斯骨折进行了固定（3.1%）。发生率最高的是防守线锋（10名运动员），其中发生率最高的是近端锋（5.1%，79名运动员中有4名）。所有骨折均采用髓内螺钉固定。3处（8%）骨折存在骨不连。与无骨折修复史的运动员相比，有骨折修复史的运动员在其第一个NFL赛季未被选秀（P = 0.61）、参赛（P = 0.23）或首发（P = 0.76）的风险并无显著差异。
有琼斯骨折修复史的运动员在其第一个NFL赛季未被选秀或参赛减少的风险并不显著。
