Abstract:
Experience with electrophysiological monitoring during surgery of the spinal vertebrae and spinal cord is reviewed. The cerebral somatosensory evoked potential (CSEP) is used to monitor spinal cord conductivity during mechanical manipulation of the vertebrae, most commonly during correction of the curvature of the spine. Abnormal CSEPs were recorded in 11 out of approximately 700 cases of scoliosis surgery. During percutaneous cordotomy, intracord evoked and spontaneous potentials are recorded in order to identify the cord structure. Experiment models are also discussed.
