Low back pain leads to major social and economic consequences. Treating chronic low back pain with radiofrequency denervation showed no significant improvement.
Treating chronic low back pain with radiofrequency denervation resulted in either no improvement or no clinically important improvement in three randomized trails, reveals a new study published by JAMA. Low back pain causes more //disability than any other condition and has major social and economic consequences. Even though radiofrequency denervation is a commonly used treatment, high-quality evidence for its effectiveness is lacking.
‘Radiofrequency denervation is a procedure that is performed with different techniques like the application of an electric current to the pain-conducting nerve.’
Esther T. Maas, Ph.D., of Vrije Universiteit Amsterdam, the Netherlands, and colleagues report the results of three randomized clinical trials that were conducted in 16 pain clinics in the Netherlands.Trial participants, who were unresponsive to conservative care, had chronic low back pain originating in potential sources of the spinal column: the facet joints, sacroiliac joints, or a combination of facet joints, sacroiliac joints, or intervertebral disks.
All participants received a 3-month standardized exercise program and psychological support if needed. Participants in the intervention group received radiofrequency denervation as well, which is usually a 1-time procedure, but the maximum number of treatments in the trial was three.
Among 681 participants who were randomized, 599 (88 percent) completed the 3-month follow-up, and 521 (77 percent) completed the 12-month follow-up.
The researchers found that two trials assessing radiofrequency denervation for the sacroiliac joints and a combination of the facet joints, sacroiliac joints, or intervertebral disks showed a statistically significant but not clinically important improvement in pain intensity three months after the intervention.

"The findings do not support the use of radiofrequency denervation to treat chronic low back pain from these sources," the authors write.
