Nearby healthy nerves are not damaged during the procedure. The heat causes a lesion that prevents the nerve from sending pain signals to your brain. An electrode is inserted into the top of the needle, which sends the radio waves through the needle to the targeted nerve. When radiofrequency is applied to nerve tissue, it damages nerves, which prevents or stops the pain signal from reaching the brain and results in pain relief.ĭuring a radiofrequency ablation procedure, a small hollow needle is inserted into the targeted nerve that is causing pain. Radiofrequency ablation uses heat produced from radio waves to target diseased tissue. Facial pain caused by trigeminal neuralgia.Chronic pain caused by conditions including arthritis of the spine ( spondylosis) and sacroiliac (SI) joint pain. Radiofrequency ablation is used to treat: What conditions can be treated with radiofrequency ablation? Reduce the number of pain medications taken.The goals of radiofrequency ablation are to: Why is radiofrequency ablation (RFA) done? RFA can provide lasting relief for people with chronic pain, especially in the lower back, neck and arthritic joints. The heat destroys that area of the nerve, stopping it from sending pain signals to your brain. Radiofrequency ablation (RFA), also called radiofrequency neurotomy, uses radio waves to create a current that heats a small area of nerve tissue. Radiofrequency ablation (RFA) targets specific parts of a nerve so that it stops sending pain signals to your brain.
