Introducing a supernumerary muscle in the anterior compartment of the hand: A cadaveric study

ABSTRACT

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