Distal biceps tendon ruptures (DBTR) are uncommon injuries in 40- to 50-year-old men but occur at a younger age in the athlete population. The distal biceps tendon is an important supinator of the forearm and flexor of the elbow. A complete injury results in limiting function in the upper extremity. The current review evaluates the different options in management and the current literature on return to play in athletes.
The distal biceps tendon inserts on the posterior aspect of the radial tuberosity as two independent heads. The long head footprint is more proximal and posterior giving it a better lever arm for supination. The short head footprint is more distal and anterior giving it a better lever arm for flexion. Surgical anatomic repair is highly recommended among the athlete population, to restore proper function of the upper extremity. There is scarce literature on return to play among athletes. The most recent studies on high-performance athletes are on National Football League (NFL) players. These studies showed that 84-94% of NFL players returned to play at least one game after distal biceps repair. Compared to matched control groups, there was no difference in the player's performance after surgery. Anatomic repair of DBTR results in excellent outcomes, high return to work, and high rate of return to play among athletes. When compared to matched control groups, NFL players have the performance score and play the same number of games after surgery.
肱二头肌远端肌腱断裂（DBTR）在40至50岁男性中是不常见的损伤，但在运动员群体中发病年龄较轻。肱二头肌远端肌腱是前臂重要的旋后肌和肘部屈肌。完全损伤会导致上肢功能受限。本综述评估了治疗的不同选择以及目前关于运动员重返赛场的文献。
肱二头肌远端肌腱以两个独立的头附着于桡骨粗隆的后侧。长头附着点更靠近近端和后侧，使其具有更好的旋后杠杆臂。短头附着点更靠近远端和前侧，使其具有更好的屈曲杠杆臂。强烈建议在运动员群体中进行手术解剖修复，以恢复上肢的正常功能。关于运动员重返赛场的文献很少。关于高水平运动员的最新研究是针对美国国家橄榄球联盟（NFL）球员的。这些研究表明，84%至94%的NFL球员在肱二头肌远端修复后至少重返赛场一场。与匹配的对照组相比，球员术后的表现没有差异。DBTR的解剖修复在运动员中产生了优异的结果、高重返工作率和高重返赛场率。与匹配的对照组相比，NFL球员术后的表现得分相同，比赛场次也相同。
