Variation in the termination of musculocutaneous nerve

The present report describes a case of variation of the musculocutaneous nerve observed in a middle aged Indian male cadaver during routine educational dissection. We examined a variation in the termination of musculocutaneous nerve in right upper limb. After piercing coracobrachialis muscle musculocutaneous nerve divided into lateral cutaneous nerve of the forearm and another branch that joined with median nerve below the insertion of the coracobrachialis. This abnormal branch coming from the musculocutaneous nerve had a very close oblique course over the brachial artery. Precise knowledge of variations of this report may help to plan a surgery in the region of axilla and arm, traumatology of the shoulder joint and plastic and reconstructive repair operations.
