Abstract

Introduction: Palmaris longus, one of the superficial flexor muscles of the anterior compartment of the forearm is the most variable muscle of the upper limb. Purpose: To note the variations of palmaris longus for tendon grafts. Methods: Forty formalin-fixed upper limb specimens of South Indian population were dissected to note the variations of Palmaris longus muscle. Results: Out of the forty upper limb specimens, two variants of the palmaris longus were noted. In one specimen, a reversed palmaris longus was noted. It had a long tendinous origin with a muscle belly and a short flat tendon at insertion. The tendon inserted partly into the flexor retinaculum and partly into palmar aponeurosis. In another specimen, apart from the normal palmaris longus muscle, an additional smaller muscle was noted. It was the Palmaris profundus. This muscle took origin in the form of a tendon from the middle of the shaft of the radius, continued as a muscle belly and then terminated as a tendon which later inserted into the flexor retinaculum, close to the tendon of palmaris longus muscle. At its insertion, the superficial palmar branch of radial artery hooked it. The anterior interosseous nerve supplied the Palmaris profundus. Conclusion: These variations are worthy to be noted for tendon grafts.
