Clinical Correlations of Accessory Head of Flexor Pollicis Longus with Anterior Interosseous Nerve Syndrome: A Case Report

Abstract

During routine cadaveric dissection done for the undergraduate students in 2013, at the Department of Anatomy, Mysore Medical College and Research Institute, Mysore an accessory muscle head in the left forearm of a male cadaver was observed which was supplied by a branch of anterior interosseous nerve. Gantzer's muscle is an accessory portion of the flexor pollicis longus or flexor digitorum profundus muscle located in the forearm which is considered an anatomical variant. The adequate knowledge regarding muscular variations is essential not only for anatomists but also for surgeons while approaching forearm for tendon transfer of flexor digitorum superficialis or anterior approach of elbow.
