Radiofrequency Ablation (RFA)

Long-Lasting Pain Relief by Deactivating Pain Nerves

Radiofrequency ablation (RFA) is a minimally invasive procedure that uses heat from radio waves to disable small pain nerves. It’s most often used for patients with facet joint arthritis or sacroiliac joint pain after diagnostic nerve blocks confirm the pain source.

What is RFA?

In simple terms: RFA uses heat to stop pain signals from specific nerves.
Scientifically: RFA involves percutaneous placement of radiofrequency electrodes adjacent to medial branch or lateral sacral branch nerves, applying thermal coagulation (80°C for 60–90 seconds) to denature nociceptive fibers and provide long-lasting relief.
