Dermatomal evoked potentials are being used to obtain accurate information concerning the viability of specific nerve root pathways and the quality and extent of nerve root decompression. Twelve patients with quantifiable weakness were selected and tested before, during, and after surgery. Nine patients showed dramatic intraoperative electrical improvement, including decreased latencies and/or increased amplitudes; all had postoperative relief of pain and motor return. Three patients showed… CONTINUE READING
