Neurophysiological studies of autogenous sural nerve grafts.

摘要: Sixteen autogenous sural nerve grafts used for ulnar and median injuries in the forearm have been studied neurophysiologically up to two a half years after operation. Motor sensory conduction studies revealed slow but sustained improvement during follow-up period. By years, motor velocity across graft itself reached most cases 40 85% of contralateral normal limb. Some reduction was observed uninjured proximal this less marked. Sensory action potentials were obtained 44% nerves 18 months although all amplitude their velocity, greatly reduced.
