Radiofrequency ablation (RFA) is a minimally invasive option used to relieve back pain caused by inflamed facet joints, which are small joints between the vertebrae. This treatment uses carefully targeted heat from radio waves to temporarily “turn off” the nerves that are sending pain signals to the brain.
It’s typically recommended for patients whose back pain hasn’t improved with other treatments like physical therapy or anti-inflammatory medications. Before the procedure, doctors perform diagnostic tests to confirm the specific joint causing pain.
RFA is done while you’re awake, with local anesthesia to numb the area. A thin needle is placed using live X-ray guidance, and heat is applied to the nerve. The whole procedure takes about 30–45 minutes, and most people go home the same day.
