Communication Between Radial And Ulnar Nerve At A High Humeral Level.

ABSTRACT

Various communications between the different branches of brachial plexus have been reported by many authors but the communication between the radial and ulnar nerve; the branches of posterior and medial cords of brachial plexus in the arm is very rare. It features the communicating ramus travelling from proximal radial nerve and distal ulnar nerve at a high humeral level in the right arm of a 56 year old male cadaver. Knowledge of such variations may be of importance in the evaluation of certain entrapment phenomenon of ulnar nerve or unexplained sensory loss after trauma or surgical interventions in that particular area is also of clinical significance in anaesthetic blocks.
