Radiofrequency Ablation RFA

Radiofrequency Ablation, also known as Facet Rhizotomy and Medial Branch Neurotomy, utilizes a radiofrequency probe to electrochemically denervate the medial branches, thus rendering the facet joints pain free. The medial branches do in fact re-innervate over time to a mild degree, whereby the RFA can be done again.

How does Radiofrequency Ablation Work?

First the medial branch is localized using sensory / motor stimulation and imaging. Next, the targeted area is locally anesthetized for comfort. Finally, the RFA device generates a radial sphere of "electrical frequency" at 80 degrees for 90 seconds at the tip of the probe over each Medial Branch Block. Applying the radiofrequency energy to the facet joint nerve involves placing an insulated wire near the nerve tissue.

Advantages of Radiofrequency Ablation

RFA is a semi-permanent procedure for facet joint pain in the lower back. No steroid is necessary for this procedure. It is useful for axial low back pain and neck pain from degenerative spine conditions even after surgery. Little risk to the patient if it is done properly by a board certified physiatrist. It is important to note that this procedure is not recommended for patients suffering from neuropathic radicular pain.
