Radiofrequency ablation, also called rhizotomy, is a nonsurgical, minimally invasive procedure that uses heat to reduce or stop the transmission of pain. Radiofrequency waves ablate, or “burn,” the nerve that is causing the pain, essentially eliminating the transmission of pain signals to the brain.

This procedure is most commonly used to treat chronic pain and conditions such as arthritis of the spine (spondylosis) and sacroilitis. It is also used to treat neck, back, knee, pelvic and peripheral nerve pain. The benefits of radiofrequency ablation include: avoiding surgery, immediate pain relief, little to no recovery time, decreased need for pain medication, improved function, and a quicker return to work and other activities.
