The value of radiofrequency facet rhizotomy in the treatment of patients with chronic neck and low back pain problems is assessed on the basis of experience with 117 consecutive patients. Only patients with positive responses to facet blocking with local anesthetic were selected. ⋯ Average follow-up time was 13.7 months. We conclude that radiofrequency rhizotomy is a valuable tool in the treatment of chronic neck and low back pain.
