The results of percutaneous facet rhizotomy for the treatment of low back and sciatic pain in 30 patients are reported. Satisfactory results were obtained in 76% of cases. No complications were found. This procedure should be tried in every patient with low back and extremity pain and no major neurological deficit before resorting to laminectomy.
