ABSTRACT Many muscular variations of the upper extremity have been reported. The majority of these varia-tions are associated with forearm muscles. Howev-er, the muscular variations of the hand are uncom-mon. In the current study we found a unique su-pernumerary muscle in the right hand of a middle-aged male cadaver. This muscle originated from the one of the tendons of flexor digitorum superfi-cialis (FDS) muscle that goes to the index finger and then traversed 5 cm distally to attach the same tendon. The knowledge of muscular varia-tions is very essential for surgeons and clinicians to plan the standard surgical approaches.
