Abstract: Variations in the branching pattern of the brachial plexus is not uncommon. But the variation found in the present case in a male cadaver during routine dissection is a rarest one. A communication was found between the radial and ulnar nerves in the upper arm. In addition the median nerve was formed by three roots, one medial and two lateral roots. Knowledge of the variations of brachial plexus will provide useful information for the surgeons for doing flap surgeries and also to minimize the possible complications of regional anesthesia.
