Handbook of Spinal Cord Monitoring

Surgery for the treatment of deformities such as scoliosis carries a small but significant risk of damage to the spinal cord through inadvertent compression or interference with the blood supply. Electrophysiological techniques, principally those for recording sensory and motor evoked potentials, offer a means of continuously assessing the conduction of nerve signals up and down the spinal cord and hence the possibility of detecting a defect at an early stage, when the cause may be reversible.
