The posterior antebrachial cutaneous nerve (PABCN) branches from the radial nerve in the axilla. The posterior antebrachial cutaneous nerve branches from the radial nerve just distal to the posterior brachial cutaneous nerve (PBCN) in the axilla and they course through the arm in closely to each other. In the proximal forearm, the posterior antebrachial cutaneous nerve is found on the lateral border of the brachioradialis muscle. The terminal branches innervate the posterior aspect of the forearm distally. Gerwin et al recommended identifying the lower lateral brachial cutaneous nerve first when approaching the humerus posteriorly. It can be traced proximally to safely identify the radial nerve before any proximal exposure of the shaft is done. Gerwin et al in their review also found that the radial nerve crossed the posterior aspect of the humerus an average of 20.7 +/- 1.2 centimeters proximal to the medial epicondyle to 14.2 +/- 0.6 centimeters proximal to the lateral epicondyle. In their review, Zlotolow et al. review the multiple surgical approaches to the humerus. Illustration A depicts the course of the PABCN and its relation to the PBCN and the radial nerve
