Abstract

Variations in the musculocutaneous nerve are very common. But, the absence of the nerve is rare. One such case of total absence of musculocutaneous nerve which was observed in a male cadaver during routine dissection is reported here. The coracobrachialis muscle which is normally supplied by the musculocutaneous nerve was innervated by a direct branch of lateral cord of brachial plexus, whereas biceps brachii and brachialis muscles are supplied by branches from the lateral aspect of median nerve. Lateral cutaneous nerve of forearm was arising from the lateral aspect of median nerve in common with nerve to brachialis and was partly supplying the area of innervation of a normal lateral cutaneous nerve of forearm. The remaining of its area was supplied by the posterior cutaneous nerve of forearm, a branch of radial nerve. Further, a literature review about the case was done and the surgical and clinical importance of the case was discussed.
