A new application of TCE-MEP:: Spinal cord monitoring in patients with severe neuromuscular weakness undergoing corrective spine surgery

The importance of spinal cord monitoring during corrective scoliosis surgery is widely acknowledged. However, for patients with preoperative neurologic deficits, its use is technically difficult. In this article, we describe intraoperative transcranial electrical motor evoked potential (TCE-MEP) monitoring in nine patients with neuromuscular weakness who underwent corrective scoliosis surgery. In each patient, eight muscle groups were recorded and stable responses were obtained in all patients. We conclude that TCE-MEP pen-nits monitoring of the spinal cord in patients with disturbed motor function.
