Electrophysiological monitoring, including cerebral somatosensory evoked potentials (CSEPs), helps assess spinal cord function during scoliosis surgery. Abnormal signals were noted in 11 of 700 surgeries, indicating potential for monitoring spinal cord conductivity.

Area of Science:

  • Neurosurgery
  • Spinal Surgery
  • Neurology

Background:

  • Electrophysiological monitoring is crucial for assessing spinal cord integrity during complex spinal surgeries.
  • Cerebral somatosensory evoked potentials (CSEPs) are a key technique for evaluating spinal cord conductivity.
  • Scoliosis correction surgery often involves mechanical manipulation that can risk spinal cord injury.

Purpose of the Study:

  • To review the utility of electrophysiological monitoring in spinal surgery.
  • To highlight the application of CSEPs in monitoring spinal cord function during scoliosis correction.
  • To discuss the recording of evoked and spontaneous potentials during percutaneous cordotomy.

Main Methods:

  • Review of surgical cases involving electrophysiological monitoring of the spinal cord.

  • Utilizing cerebral somatosensory evoked potentials (CSEPs) to assess spinal cord conductivity.
  • Recording intracord evoked and spontaneous potentials during percutaneous cordotomy.

    • Main Results:

    • Abnormal CSEPs were identified in 11 out of approximately 700 scoliosis surgery cases.
    • Electrophysiological monitoring provides valuable data on spinal cord status during vertebral manipulation.
    • Specific techniques are employed to identify cord structures during procedures like percutaneous cordotomy.

    Conclusions:

    • Electrophysiological monitoring, particularly CSEPs, is effective in assessing spinal cord conductivity during scoliosis surgery.
    • Abnormalities detected via CSEPs can signal potential neurological compromise.
    • The techniques discussed are vital for intraoperative neuroprotection during spinal procedures.
