Intraoperative neurophysiological monitoring in spinal surgery.

Subspecialty: Spine

Type: Clinical Summary

Intraoperative neurophysiological monitoring (IOM) during resection of intramedullary spinal cord tumor is grounded in real‑time assessment of the spinal cord’s ascending and descending long tracts to detect imminent mechanical or ischemic injury and allow immediate corrective action. This review synthesizes evidence and methods for the principal modalities—SSEP, MEP (including muscle MEP and epidural D wave), plus related techniques (dorsal‑column mapping, EMG, triggered EMG) and perioperative management (anesthesia, thresholds, recovery maneuvers)—with diagnostic performance data and practic…
