AbstractIt is more than 60 years since averaged somatosensory evoked potentials (SEPs) were devised. During this period, other evoked potentials including spinal cord evoked potentials and motor evoked potentials (MEPs) were developed. In cases needing identification of the pathologic level of myelopathy and monitoring the function of the spinal cord, these evoked potentials are now indispensable. The combination of these evoked potentials (multimodality monitoring) has been demonstrated to be sensitive and specific for detecting intraoperative neurologic injury during spine surgery. Although there is still a low level of evidence that intraoperative evoked potentials reduce the rate of new or worsened perioperative neurologic deficits, it is recommended to monitor MEP for thoracoabdominal aortic surgery and multimodal evoked potentials including at least spinal cord evoked potentials and MEP for spine surgery, when the spinal cord is considered to be at risk.
