Abstract
Intraspinal recordings of somatosensory evoked potentials have been performed at this centre for several years in patients undergoing radio-frequency percutaneous cervical cordotomy for the relief of malignant pain (Campbell and Lipton, 1983, 1984,1985; Campbell and Bowsher, 1985; Campbell, 1985). These recordings have been used both as a research tool in the investigation of sensory transmission in the human spinal cord and as an extra aid for accurate positioning of the lesion electrode within the spinal cord. Some open neurosurgical procedures also require accurate localization of spinal tracts and it was felt that similar techniques may prove valuable in these cases. As a result, responses evoked by peripheral nerve stimulation have been recorded from various positions within the spinal cord during ablative neurosurgical procedures. Somatosensory evoked potentials have been recorded from the cords of 6 patients undergoing destruction of the dorsal root entry zone (DREZ), 2 patients having a midline myelotomy and 1 patient on whom an open thoracic cordotomy was performed.
