Abstract

Musculocutaneous nerve is the nerve of anterior compartment of the arm & it supplies the muscles of front of the arm and skin on the lateral aspect of forearm. It is the terminal branch of lateral cord of brachial plexus. Variations of musculocutaneous nerve have been reported by previous authors. Here we present a case of unilateral anomalous origin of musculocutaneous nerve along with an additional nerve supply to biceps brachii and brachialis during routine undergraduate dissection in the left arm of 55 years old male cadaver. These variations should be searched during surgical reduction of fractures by orthopaedicians and should not be overlooked by surgeons during nerve repair to prevent damage to the additional branch which supplies muscles of anterior compartment of arm.
