両側性前骨間神経麻ひの一例

Abstract

A Case of bilateral anterior interosseous nerve plasy in discussed and the literature reviewed.A 25 old man developed pain in his left elbow flexion side. As the pain subsided, the patient noted the inability to flex his left index finger DIP joint. He had not had any previous trauma nor medical history related to the problem. Showing no recovery, he underwent operation three months after the onset. The operation, showed no evidence of the entrapment of the anterior interosseous nerve. Two months after the operation, the patient recovered functions of the index FDP.Five years later the patient experienced pain in his right elbow flexion side. The next day, he could not flex the IP joint of the thumb nor the DIP joint of the index finger actively. We performed neurolysis eight months after the onset, and found fascicular constriction of the anterior interosseous nerve fasciculus within the main trunk of the median nerve by interfascicular neurolysis.
