Percutaneous implantation of chronic spinal cord electrodes for control of intractable pain: preliminary report.

A percutaneous technique is described for implanting a dorsal or ventral column stimulator for pain control with minimal surgical trauma. If the patient does not respond to percutaneous on-surface spinal stimulation, a percutaneous cordotomy can be carried out, as the needle is already in the correct position. Stimulation of the cord at the C1-2 level can be used for treatment of trigeminal neuralgia.

Electrical stimulation of the ventral and dorsal columns of the spinal cord for relief of chronic intractable pain: preliminary report.

Serious questions are raised as to whether electrical control of pain is related to stimulation of the dorsal columns per se or the conduction of the electrical impulse via the cerebrospinal fluid to the ventrolateral columns. Percutaneous on-surface spinal cord stimulation is advocated as an accurate screening method before implantation. Of 27 patients who underwent dorsal column stimulator implants, the last three patients also underwent ventral column stimulator implants. Results in the patients with both implants tend to predict much better results with the possibility that ventral column stimulation alone is sufficient.

Back Pain↗

A new approach to the failed, failed back syndrome.

A new screening test and operative technique for the relief of intractable pain in the failed back syndrome has been devised and has yielded a 72% success rate on short-term follow-up (9--30 months) in 26 patients. This syndrome is thought to represent pain emanating from permanently damaged nerve roots and not from the arachnoiditis that was always present. Multiple spinal nerve blocks are carried out sequentially in the foramina under local anesthesia and fluoroscopic control, and if fewer than three nerves are implicated in the causation of the major portion of the patient's pain syndrome, a microsurgical dorsal root rhizotomy in which not more than two contiguous roots are severed is performed. This procedure can be adopted despite severe adhesive arachnoiditis.
