Entrapment of the median nerve after dislocation of the elbow.

An unusual case of posterior dislocation of the elbow, complicated by entrapment of the median nerve, is reported. Entrapment occurred in the reduction of an associated medial humeral epicondyle fracture. Because the nerve was not in the joint, differentiating the entrapment from a nerve traction injury was difficult. Careful diagnosis and delayed specific surgery can secure an excellent outcome.
