摘要：In a routine dissection conducted in the Department of Anatomy, Amrita School of Medicine Kochi, additionalorigins of the first and second lumbricals were observed on the right hand of a male cadaver. The additionalbelly originated from the radial side of the tendon of flexor digitorum superficialis (FDS) of the index finger,deep to the flexor retinaculum. Distally the tendon of both bellies united and inserted to the dorsal digitalexpansion of the index finger. In the case of the second lumbrical the additional belly arose from the ulnar sideof the tendon of Flexor digitorum profundus (FDP) of the index finger and inserted into the dorsal digitalexpansion of middle finger. Knowledge of possible variations helps the clinician find aetiology for variouscompressive syndromes so that treatment modality can be tailored and customised. This presentation will addto the compendium of information.
