A combined anomaly comprising triple muscular variations - An aberrant flexor indicis profundus lateralis associated with gantzer's muscle and flexor indicis profundus

Abstract

Aberrations in the deep wrist flexors are frequently documented. These varied muscles might account for anterior interosseous nerve compression syndrome. The present study describes a case with three variations in the deep flexor of wrist comprising two separate small muscle bellies with their tendons and a higher level cleavage of the lateral tendon of flexor digitorum profundus muscle. Such a triple anomaly is a rare occurrence that has to be borne in mind by hand surgeons in case of nerve entrapment syndromes.
