title: Accessory head of the biceps brachii. Case report demonstrating clinical relevance.
abstract: Although anatomic variations in the origin of both the coracobrachialis or biceps brachii have been observed, there have been no previous reports of clinical relevance. In a 22-year-old man, recognition and mobilization of an accessory long head of the biceps brachii was necessary for adequate exposure of the shoulder joint dislocation through a deltopectoral incision.
