Abstract

Compression ulnar neuropathy was predicted by Guyon in 1961,following his anatomical studies of the ulnar tunnel. Nearly a half century later Ramsey Hunt first reported isolated ulnar motor paralysis in the hand, due to chronic occupational trauma. Many authors has tried to describe the etiology of the ulnar nerve compression syndrome at or around the wrist. That is most frequently caused by ganglion, occupational neuritis, thrombosis of the ulnar artery, thickening of volar ligament or different kinds of trauma (e.g. fractures of the carpal bones). Now we experienced a case of the ulnar nerve compression syndrome at distal forearm by an anomalous branch of the ulnar nerve by piercing the distal tendon of the flexor carpi ulnaris.
