AIM: To show the anatomical variation in the nerve supply of extensor carpi radialis brevis. RESULTS: The nerve to extensor carpi radialis brevis was found arising from the superficial branch of radial nerve, i.e. the radial nerve proper. CONCLUSION: The awareness of varition or nerve supply to extensor carpi radialis brevis from superficial branch of radial nerve is clinically important of surgeons, orthopaedicians, anaesthetists, physiotherapist & plastic surgeons to avoid damage to nerve during surgery and in interpretation of results. AIM: To show the anatomical variation in the nerve supply to extensor carpi radialis brevis, found in routine dissection. RESULTS: It is found that extensor carpi radialis brevis is supplied by branch of radial nerve (i.e) radial nerve proper in our dissected specimen.

Variations in the anatomy of brachial plexus are common. So is the median nerve anatomy. Knowledge of the variations contributes to the surgeons planning and curative intent during surgical repair of the Median nerve deficiencies. During routine brachial plexus dissections of cadavers for undergraduate students a variation of formation and innervations by the median nerve was identified at our department of anatomy, Rangaraya medical college, kakinada. A total of forty two brachial plexuses were explored and a variation in a male body on the left side was noted.
