The ulnar nerve is considered the thickest terminal branch of the medial cord in the brachial plexus and most authors does not mention the possibility of this nerve emitting branches to the arm. However, some studies reported that the ulnar nerve could supply the medial head of triceps brachii muscle. The main objective in this study was identifying the presence of ulnar nerve branches in triceps brachii muscle. Sixty upper limbs of adult Brazilian corpses of both sexes were used. The estimated age was between 25 and 80 years old. Every studied piece had the nerves and their branches quantified and measured with a manual mechanic caliper. The branches were photographed and had the data registered in individual files. Were found ulnar nerve branches for all the heads of triceps brachii muscle: 1 branch (9,1%) to lateral head, 2 branches (18,1%) to long head and 8 branches (72,7%) to medial head. Thus, we can conclude that the contribution of ulnar nerve to triceps brachii muscle constitutes an important anatomical variation.Key words: Ulnar nerve; Triceps brachii muscle; Innervation.

Some cases of cubital tunnel syndrome are caused by anatomical abnormalities such as the epitrochleo-anconeus muscle or snapping and bulkiness of the medial head of the triceps brachii muscle. We report a rare cause of cubital tunnel syndrome that has not been reported previously. It was caused by an abnormal insertion of the medial head of the triceps muscle into the medial epicondyle. The clinical course and operative findings are described.

Abstract Introduction: Various studies have been done on triceps brachii muscle but the description of the highest extent of lateral and medial head of triceps brachii muscle remained unexplored that is why this study was undertaken to know the extent of their proximal attachments in relation to anatomical neck of humerus and capsule of shoulder joint. Materials and Methods: The shoulder region of 50 formalin fixed upper limbs were dissected to explore the capsule of shoulder joint to reach the highest extent of lateral & medial head of triceps brachii muscle where the nature of fibres, fleshy or tendinous was noted. Oblique and vertical distances of proximal attachment of lateral & medial head of triceps brachii muscle to the anatomical neck of humerous was measured with the help of a sliding caliper. Results: Medial head of triceps brachii muscle in all the cases was fleshy in origin while that of lateral head; fibres were fleshy and tendinous in 82% & 18% of cases, respectively. Fibres of lateral and medial head were blending with the capsule of shoulder joint in 28% & 6% of cases respectively. Maximum cases of lateral head were having their oblique and vertical distances between 21-40 mm (64% & 58% respectively) while those for medial head were >40 mm (68% & 74% respectively). Conclusion: Accurate knowledge of these anatomical patterns of triceps brachii muscle are of considerable clinical importance in the conduct of reparative open access and arthroscpic surgeries around the shoulder and the fracture management of the upper end of humerus.
