Olecranon fracture sustained in arm wrestling.

This case report describes an arm-wrestling injury in which a violent triceps contraction was determined to have caused an olecranon fracture. Such a fracture has not been reported in arm wrestling; more typical are fractures of the humeral shaft or medial epicondyle. The authors suggest awareness of this potential and recommend appropriate radiographic studies for injuries involving intense muscle contraction. The patient was treated conservatively. After rehabilitation, he was able to return to his job, which involved lifting, but did not resume arm wrestling.
