Abstract

Anterior interosseous nerve palsy is known to occur uncommonly because of its compression by the accessory head of flexor pollicis longus(AHFPL) in the forearm. During routine educational dissection, we found 7 AHFPLs in 12 upper limbs of 6 adults Korean Jeju islander cadavers, which inserted onto flexor pollicis longus. Three AHFPLs of them arose from coronoid process of the ulna, and the others arose independently from the flexor digitorum superficialis (FDS). Using the topographical relationship of the anterior interosseous nerve to the AHFPL, all anterior interosseous nerve was crossed the tendinous part of the AHFPL. This study has shown that there are discrepancies in the origin of AHFPL and the location of the anterior interosseous nerve in Koreans, which is supposed to be related to unique genetic pool in Jeju Island.
