An International Survey on the Practice of Lumbar Radiofrequency Ablation for Management of Zygapophyseal (Facet)-Mediated Low Back Pain.

This survey study provides a summary of the application of lumbar RFA for the treatment of axial low back pain in the real-world setting. We highlight a significant portion of providers who perform lumbar RFA yet do not have pain fellowship training at an ACGME-accredited institution or do not maintain current pain medicine board certification. We also report deviations from standard practice, specifically the type of local anesthetic used for comparative diagnostic blocks and the omission of contrast injection during diagnostic blocks.
