Background: The extensor compartment of the arm is occupied by triceps muscle, through which runs the radial nerve and profunda brachii artery. Triceps arises by three heads namely long head, lateral head and medial head. Triceps is innervated by radial nerve (C6,C7 and C8) with separate branches for each head. Triceps muscle and its main motor nerve namely the radial nerve have multiple connection modalities. Each of the motor branches to triceps might be used as a donor for nerve transplantation
