Abstract
The aim of this study was to demonstrate the distribution and branching of terminal branch of superficial radial nerve in Koreans. We dissected 28 upper extremities of 14 cadavers. The radial nerve became superficial in the distal forearm, approximately 76 mm proximal to the styloid process. The superficial radial was found to divide into 2 terminal branches at a point 47 mm proximal to styloid process. The anterior and posterior terminal branches passed 7.0±3.0 mm anterior to and 10.0±3.0 mm posterior to the styloid process, respectively. Fifteen of the 28 extremities revealed a communication between the superficial radial nerve and the lateral antebrachial cutaneous nerve. The mean forearm length was 235±
15 mm and the mean ratio of forearm length to the distance from styloid process to superficial radial nerve piercing point was 32%. Therefore, in Koreans, antidromic superficial radial nerve conduction study should be performed with stimulation at 7 cm proximal from styloid process or 10 cm proximal from active recording electrode.
