Abstract

The internal anatomy of the median nerve in the region of the elbow has been studied by microdissection in 20 cadavers. Gross branching patterns were studied in an additional 14 cadavers. There are four major branches or branch groups: I to pronator teres, II to flexor carpi radialis, flexor digitorum superficialis, and palmaris longus; III to the anterior interosseous nerve; and IV to flexor digitorum superficialis. Three of these could be traced proximally within the main trunk of the median nerve, the average being I - 10 cm; III - 7.5 cm; IV - 2 cm. This information should have clinical applications in repair and grafting of the median nerve near the elbow and in understanding clinical nerve compression syndromes. © 1992.
