Commissural myelotomy

The effect of commissural myelotomy in 24 cases with intractable pain is described. The operative technique employed with the operating microscope or magnifying glasses and a special myelotome is outlined. The results suggest an outstanding advantage in patients with bilateral metastases from malignancies except intrapelvic metastases. Patients with lumbar arachnoiditis showed a total failure of pain relief after 2 to 5 years, in spite of good relief temporarily.
