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.

Operative Findings

Clinical features and X-rays of thirty-four cases with cubitus varus deformity were analysed in order to explain the occurrence of tardy ulnar nerve palsy caused by cubitus varus deformity. Cubitus varus cases with tardy ulnar nerve palsy, compared to cases without it, were older at the first visit to the clinic for cubitus varus deformity. There were no other differences between the two groups in clinical features. Computed tomography showed that the olecranon moved to the ulnar side against the olecranon fossa. Operative findings showed that the medial head of triceps brachii shifted medially and covered the ulnar nerve. Both from computed tomography and operative findings we conjectured the possibility that tardy ulnar nerve palsy was caused because the ulnar nerve was compressed by the forward medial movement of the medial head of the triceps brachii caused by cubitus varus deformity.

Complex Origin

Abstract The coracobrachialis muscle (CBM) originates from the apex of the coracoid process, in common with the short head of the biceps brachii muscle, and from the intermuscular septum. Both the proximal and distal attachment of the CBM, as well as its relationship with the musculocutaneus nerve demonstrate morphological variability, some of which can lead to many diseases. The present case study presents a new description of a complex origin type (four-headed CBM), as well as the fusion of both the short biceps brachii head, brachialis muscle and medial head of the triceps brachii. In addition, the first and second heads formed a tunnel for the musculocutaneus and median nerves. This case report has clear clinical value due to the split mature of the coracoid process, and is a significant indicator of the development of interest in this overlooked muscle.
