Clinical Usefulness of Spinal Cord Evoked Potentials
Spinal cord evoked potentials were recorded from the cervical or thoracic epidural space following spinal cord stimulation in 21 patients with cervical spondylotic myelopathy, 18 with ossification of the posterior longitudinal ligament and 7 with spinal cord injury due to fracture-dislocation. Thirteen cases were monitored during surgery. Amplitude or waveform abnormalities were detected in the majority of cases, and could often be used to determine the affected vertebral levels. Amplitude was sometimes greatly increased after decompressive surgery.
