High cervical percutaneous cordotomy in intractable pain.

The authors report on 200 cervical percutaneous cordotomies in 146 patients who were suffering from intractable pain. In order to assess the success rate and the incidence of relapse, the neurological findings immediately post-operatively were compared with the results of a later follow-up. The prospect of success in the treatment of pain appears to depend on the anatomical representation in the spino-thalamic tract of the region of the body which is involved. The incidence of complications and the mortality are compared with the observations of other authors and with the results of open cordotomy.
