Abstract

Anomalous muscles usually do not result in adverse symptoms but are of academic interest. However, these muscles can create neurovascular compression at times. Muscle anomalies of the upper extremity are recognized causes of peripheral nerve disorder. Koloh-Nevin Syndrome (Anterior Interosseous Nerve Syndrome) caused by the compression neuropathy of the anterior interosseous nerve in the forearm is believed to occur because of its compression by the accessory heads of flexor pollics longus (FPLah) and flexor digitorum profundus (FDPah). The above two accessory muscles are also called Gantzer's muscle. During routine cadaveric dissection, we encountered multiple Gantzer's muscles in a 60 year-old- formalin embalmed male cadaver. Along with the usual FPLah and FDPah described by Gantzer, we too observed an accessory muscle in relation to the flexor digitorum superficialis (FDS). All the three anomalous muscles had a common origin from the under cover of the FDS fibers and by fibrous band above the insertion of brachialis. The presence of multiple additional muscles in the forearm flexor compartment is rare and clinically significant.
