Neurophysiologic Detection of a Unilateral Motor Deficit Occurring During the Noncritical Phase of Scoliosis Surgery

摘要

Study DesignA four-path neurophysiologic monitoring system was designed for spinal cord monitoring during spinal surgery. It was used mainly during scoliosis surgery.ObjectiveTo evaluate the efficacy of this technique.MethodsSensory and motor pathways were continuously monitored bilaterally from skin incision to awakening, with independent evaluation of the right and left pathways for each modality.ResultsThis monitoring technique detected a trensient unilateral motor deficit that occurred during the dissection phase of spinal surgery for scoliosis before any instrumentation or mobilization of the spine.
