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.
