Lumbar Radiofrequency Ablation
The goal of a radiofrequency ablation is to prolong the relief received from a medial branch block or facet joint injection. Typically, the radiofrequency ablation relieves pain in the back for up to 6-12 months. Radiofrequency ablations are only performed once a patient receives pain relief from an injection and the appropriate source of pain has been identified.
What is a Lumbar Radiofrequency Ablation?
A radiofrequency ablation interrupts the sensory signal to the involved facet joint through the use of thermal energy that ablates the nerves. After a local skin anesthetic is applied to the patient’s back, the physician guides a needle via fluoroscopy x-ray to the transverse process bone. The needle is positioned over the bone where the nerves are typically located. Thermal energy is then delivered to create a lesion on the nerve, thus disrupting the pain signal.
