Absence of musculocutaneous nerve bilaterally with variant motor innervations of flexors of arm

Variations of the brachial plexus are of great interest for anatomists, clinicians and surgeons, in that they may be incorporated in day to day practice. A middle aged female cadaver on routine dissection showed absence of the musculocutanaous nerve bilaterally. The anterior compartment of both arms were supplied by the median nerve. The median nerve after supplying the coracobrachialis and biceps, gave a common branch for the brachialis and lateral cutaneous nerve of the forearm. The present case may be noted for its clinical and surgical significance in the variations of brachial plexus which can be useful for diagnostic and therapeutic purposes.
