A CASE REPORT ON DOUBLE FIRST LUMBRICAL

During routine dissection for first MBBS students on 70 years donated embalmed male cadaver in the Department of Anatomy, K. J. Somaiya Medical College, Sion, Mumbai, India, we observed an accessory belly of first lumbrical originating from the radial side of the most radial tendon of the flexor digitorum profundus (corresponding to the index finger) in the right hand. It passes posteriorly along the radial side of the index finger. The two bellies of first lumbricals join with each other to insert on the extensor expansion near the metacarpophalangeal joint. The photographs were taken for proper documentation. The existence of two bellies of first lumbrical should be kept in mind by surgeons operating on hand.
