The brachial plexus consists of the anterior rami of roots C5-C8 and T1. There also may be minor contributions from either C4 and/or T2. The roots then divide to form the three trunks (superior, middle, and inferior). The trunks further divide into three anterior and three posterior divisions as they pass over the first rib and dive below the clavicle. The six divisions then develop into the lateral, medial, and posterior cords as they pass into the axilla. The five primary terminal nerve branches finally formed include musculocutaneous, radial, axillary, median, and ulnar nerves (Figs. 20.2a, b). The brachial plexus typically travels with a vascular supply that is contained within a neural vascular bundle along a large portion of
