Randomized Trial of Radiofrequency Lumbar Facet Denervation for Chronic Low Back Pain

Abstract

Radiofrequency lumbar zygapophysial joint denervation results in a significant alleviation of pain and functional disability in a select group of patients with chronic low back pain, both on a short-term and a long-term basis.

Factors determining the success of radiofrequency denervation in lumbar facet joint pain: a prospective study

“…According to results of several clinical trials, RF denervation of lumbar facet joints seems to be a very effective therapy with a success rate of 43-87% after 1 year [7,12,13]. Compared to those trials, 22% success rate of our study in 1 year after therapy is disappointing.…”

Outcome of invasive treatment modalities on back pain and sciatica: an evidence-based review

“…Radiofrequency denervation vs sham treatment for chronic facet joint pain The Cochrane review included three trials that showed conflicting evidence on the short-term effect of radiofrequency lesioning on pain and disability [34,57,93]. One trial found that radiofrequency denervation statistically significantly reduced pain intensity and improved functioning at 2 month follow-up [93].…”

“…One trial found that radiofrequency denervation statistically significantly reduced pain intensity and improved functioning at 2 month follow-up [93]. Another trial showed greater improvement in RolandMorris score but not in either Oswestry score or pain score at 4 week follow-up [57].…”

Evaluation of Pulsed Radiofrequency Denervation in the Treatment of Chronic Facetjoint Pain: An Observational Study

“…A 22-gauge needle, 100-mm RF electrode, and active 5-mm tip were used. The cannula tip was placed using the "tunnel vision," per van Kleef et al (15). Once the tip needle was at the target, sensory stimulation was carried out at 50 Hz up to 0.5 V to confirm the proximity to the medial branch.…”
