Portion of a Nerve Trunk can be Used as a Donor Nerve to Reconstruct the Injured Nerve and Donor Site Simultaneously

Abstract

Abstract: This study aims to estimate the effects of using a portion of a nerve trunk to repair itself and the injured nerve simultaneously. Proximal 1/2 median nerve served as donor nerve to repair the distal 1/2 median and whole ulnar nerve. Four months postoperation, the number of myelinated axons and nerve conduction velocities of the distal half median and ulnar nerve were (2033 ± 135 and 24.6 ± 5.3 m/s) and (1138 ± 228 and 30.3 ± 7.2 m/s). It suggests that using a portion of a nearby nerve truck to reconstruct itself and the injured nerve simultaneously is a practical method for severe peripheral nerve injury.
