Variations of the musculocutaneous nerve and the median nerve, like the communications between the two, may prove valuable in the traumatology of the shoulder joint and upper arm region. These variations are important in the procedure of blocking the brachial plexus and in clinical neurology.
MATERIALS AND METHODS
The present study was conducted on 100 upper limbs belonging to 50 cadavers (Right 50 &left 50) obtained from the Department of Anatomy, Kakatiya medical college, Warangal, Telangana. Dissection of the infraclavicular part of the brachial plexus was done. The variations in the origin, course and communications with the median nerve were noted.
In 2% of the limbs the nerve was found to give one communicating branch to the median nerve after piercing the coracobrachialis.
Knowledge of possible variations between musculocutaneous nerve and median nerve is necessary to general surgeons, plastic surgeons, neurologists and orthopaedic surgeons.
