Cooled RFA vs Conventional RFA to Manage Chronic Facetogenic Low Back Pain

This is a prospective, multi-center, randomized, single-blind comparison study examining the outcomes of subjects with chronic axial low back pain that originates in the lumbar facet joints undergoing a procedure to create a radiofrequency lesion in the medial branch nerves with either Cooled Radiofrequency Ablation (CRFA) or Conventional (Standard) Radiofrequency Ablation (SRFA). Approximately 188 participants from approximately 15 sites will be enrolled into this study, with subjects undergoing either CRFA or SRFA in a 1:1 randomization scheme. Follow-up will be conducted for 12 months post-treatment, with the primary endpoint being completed at month 6. Pain, overall outcome, quality of life, pain medication use, and adverse events will be compared between the two treatment groups to determine success.
