Facet "denervation" in the treatment of low back syndrome.
Long-term pain relief occurred in 21% of patients with low back and leg pain who underwent injection or radiofrequency rhizotomy. When pain was accompanied by unequivocal limitation of straight leg raising, neither injection nor rhizotomy produced long-term relief. Leg pain improved more than low back pain. Improvement was limited to pain relief as reported to the physician and reduction of medication. There was no improvement in work or activity status. Despite the low success rate, facet "denervation" is uncommonly safe and seems to be of some usefulness in the treatment of patients with low back pain and sciatica.
