TRANSCRANIAL MAGNETIC MOTOR-EVOKED POTENTIALS IN SCOLIOSIS SURGERY

Spinal cord monitoring using SSEPs is an accepted adjunct in the surgi cal correction of spinal deformities, but does not directly assess mot or function, Motor-evoked potentials have been introduced in an effort to meet this important need, In this series of 18 patients, the feasi bility of intraoperative monitoring using transcranial magnetic motor- evoked potentials is documented, The potential value of this neurophys iologic monitoring technique, as well as the pitfalls in interpretatio n, are reviewed.
