Abstract

A retrospective review of 87 patients with loss of elbow flexion secondary to root injuries of the brachial plexus was carried out. Results of nerve grafting, direct nerve transfer with the intercostal nerve, or tendon transfer were analyzed, and treatment recommendations were developed. Nerve transfer provided good or excellent results for injuries that included avulsion of the C5 and/or C6 roots. Nerve grafts were used successfully in cases of single or combined ruptures of C5 and C6. Tendon transfers provided good or excellent results in C5-C6 or C5-C7 avulsions, where nerve grafting was not possible and transferable muscles had good strength. Somatosensory evoked potentials were necessary to demonstrate nerve root avulsions in cases in which the roots appeared ruptured on visual inspection.
