Clavicle fractures are frequent injuries in athletes and midshaft clavicle fractures in particular are well-known injuries in Ironman triathletes. In 2000, Auzou et al. described the mechanism leading to an isolated truncular paralysis of the musculocutaneous nerve after a shoulder trauma. It is well-known that nerve palsies can lead to an atrophy of the associated muscle if they persist for months or even longer. In this case report we describe a new case of an Ironman triathlete suffering from a persistent isolated atrophy of the brachialis muscle. The atrophy occurred following a displaced midshaft clavicle fracture acquiring while falling off his bike after hitting a duck during a competition.
锁骨骨折在运动员中是常见损伤，尤其是锁骨中段骨折在铁人三项运动员中是广为人知的损伤。2000年，奥祖等人描述了肩部创伤后导致肌皮神经孤立性躯干麻痹的机制。众所周知，如果神经麻痹持续数月甚至更长时间，会导致相关肌肉萎缩。在本病例报告中，我们描述了一名铁人三项运动员出现肱肌持续性孤立性萎缩的新病例。这种萎缩发生在一次比赛中撞到一只鸭子后从自行车上摔下导致的移位性锁骨中段骨折之后。
