Nerve injury can be caused by traumatic stretching of the nerve, pressure from tumours or damage from radiation therapy. Symptoms of nerve damage may include difficulty moving the arm, shoulder, hand or fingers, and impairment of the arm or hand. Nerve reconstruction is an option when the nerves are severely damaged and will not recover on their own. This is an extremely complex and lengthy operation where the surgeon rebuilds the nerve with a graft or performs and nerve transfer. With a successful Brachial Plexus Reconstruction,some patients mayregain a little mobility or sensation, providing the surgery is carriedout within a few months from the injury.
