CORACOBRACHIALIS MUSCLE PIERCED BY TWO NERVES: CASE REPORT

Year 2016, Volume: 10 Issue: 2, 0 - 0, 25.08.2016

Abstract

The brachial plexus is formed by the union of the ventral rami of C5–T1. Contributions to the plexus by C4 and T2 differ. The coracobrachialis muscle is an elongated muscle in the superomedial part of the arm. It is a useful landmark for locating other structures in the arm. Variations exist to the coracobrachialis muscle, and to the formation of the brachial plexus, its terminal branches and its relation to surrounding structures. In this report, the coracobrachialis muscle is pierced by two nerves, and one of these nerves joins the median nerve after piercing the coracobrachialis muscle. Awareness of the possible variations of brachial plexus and its surrounding structures is necessary for adequate clinical, surgical and radiological management.

Keywords: brachial plexus; coracobrachialis; median nerve; musculocutaneous nerve; unnamed nerve
