Radiofrequency Ablation

What is radiofrequency ablation?

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.

What types of conditions will respond to Radiofrequency Lesioning?

There are a multitude of chronic pain conditions that respond well to this treatment. Chronic spinal pain, including spinal arthritis (spondylosis), post-traumatic pain (whiplash), pain after spine surgery, and other spinal pain conditions are those most commonly treated with RFL. Other conditions that are known to respond well to RFL include some neuropathic pain conditions like Complex Regional Pain Syndrome (CRPS or RSD), peripheral nerve entrapment syndromes, and other assorted chronic pain conditions. A patient’s candidacy for RFL is usually determined by the performance of a Diagnostic Nerve Block. This procedure will help to confirm whether a patient’s pain improves just for the duration of the local anesthetic (or not). Patients who have little to no pain relief after a diagnostic nerve block are not candidates for a neurodestructive procedure like RF Lesioning.
