Radiofrequency (RF) denervation is also referred to as radiofrequency ablation and is a treatment used to provide longer lasting relief of facet joint and sacroiliac joint injuries. In this procedure a needle is placed near the innervating nerves of the joint (each joint has multiple nerves) and those nerves are then blocked for a prolonged period of time using radiofrequency energy. These nerves are precisely identified with electrical stimulation at low currents. Once the nerve is identified it is then lesioned. This procedure typically takes 6-8 weeks in order to see full results and is associated with 1-2 weeks of postoperative discomfort. Pulsed Radiofrequency treatments deliver less energy and utilize lower temperatures can be applied to the dorsal root ganglions when there is a specific spinal nerve that has been injured (or peripheral nerve). Very few carriers cover Pulsed RF today.
