Slide2Overview of the study
Radiofrequency denervation for chronic low back pain Maas et al (2015)
Objectives: To assess the effectiveness of radiofrequency (RF) denervation procedures for the treatment of patients with chronic LBPMethods:Evidence current up to 29 May 2014Participants: People with chronic LBP with a positive response to diagnostic block or discography
Intervention: RF denervation
Outcomes:
Primary: Pain, functional status, global improvement, health-related quality of life and complications
Secondary: Ability to work and satisfaction with treatment
Slide3Results & Conclusions

Radiofrequency denervation for chronic low back pain Maas et al (2015)
Adverse events: Few, transient events were found, such as subsiding pain and lower limb weakness. It seemed to be more common and lasted longer in the RF groupFacet joint RF denervation may have a small effect compared to placebo and steroid injections on chronic low back pain. It seems to have no effect on discogenic LBP and a small effect in the long term for sacroiliac join pain.
