Intraoperative neurophysiological evaluation of central motor conduction time during an untethering surgery: a case report

Tethered cord syndrome is a congenital disease associated with abnormal stretching of the spinal and lumbosacral roots caused by tight terminal filum. Untethering surgery performed to minimize or prevent ongoing neurological deficits in lower limbs, bladder, bowel functions. As untethering itself carries risk inducing additional neural injuries, intra-operative neurophysiological monitoring including electromyography, motor evoked potential (MEP), somatosensory potential, bulbocavernosus reflex essential for improving functional outcomes after surgery. However, as MEP reflects integrity both central peripheral nervous systems, it alone insufficient differentiate between damages nerve roots. Herein, we report first case child whom conduction time were measured during location injuries
