Radiofrequency neurotomy for lumbar pain.
(1) Chronic lumbar (lower back) pain, which affects many Canadians, imposes a large economic burden. (2) Symptoms may occur in the vertebral facet joints of 15% to 40% of patients with lower back pain. (3) Medial branch radiofrequency neurotomy is a minimally invasive outpatient procedure that reduces pain by interrupting the nerve supply to painful facet joints. (4) Four systematic reviews of this procedure offer disparate conclusions. (5) One small well designed observational study has shown positive results, but no equally rigorous randomized controlled trial has been conducted.
