Radiofrequency Ablation (RFA), also known as rhizotomy or radiofrequency neurotomy, is a non-surgical procedure used to relieve chronic lower back, neck, or arthritis-related joint pain. It uses radio wave-generated heat to disrupt pain signals from targeted nerves.
During the procedure, you lie on your stomach and receive medication to help you relax. After numbing the area, a physician uses a fluoroscope (live X-ray) to guide a cannula to the medial branch nerves. An electrode is inserted to test nerve location with a mild jolt. Once confirmed, the nerve is heated to block pain signals. Multiple nerves may be treated if needed.
After the procedure, the instruments are removed and a small bandage is applied. Some soreness is normal, and pain relief typically develops gradually over several weeks.
