An Unusual Fracture in Arm Wrestling.

In brief: Previous reports of arm wrestling fractures have involved the distal third of the humerus. What makes this case unique is that the fracture occurred at the radial neck. The mechanism of injury probably involved extreme pronation where the radial head is locked into the capitellum-an area of potential weakness. Treatment was conservative, consisting of keeping the elbow flexed, 90° in a sling.
