Radiofrequency Ablation

Radiofrequency Ablation, is a minimally invasive procedure designed to alleviate facet joint pain in the spine. This technique involves delivering controlled pulses of heat energy through radio waves to the nerves controlling pain signals from the painful joints in the back. Its objective is to interrupt the processing of pain signals originating from injured facet joints—the minute joints nestled between the vertebrae.

Typically, this method of pain management is reserved for cases where the patient’s pain remains unresponsive to conservative treatments like anti-inflammatory medications or physical therapy. The primary aim of a radiofrequency ablation is to mitigate back pain without compromising function. Preceding the procedure, diagnostic assessments are generally conducted to pinpoint precisely which joints are the source of the problem.

The Radiofrequency Ablation Procedure

During a radiofrequency ablation, the patient assumes a prone position. The procedure is conducted on an outpatient basis, typically under local anesthesia. The duration of the procedure is approximately 30-45 minutes. After numbing the targeted area, a small needle is employed to penetrate the skin covering the spine. By focusing concentrated heat, the affected nerve(s) are targeted, blocking the transmission of pain signals to the brain.

Fluoroscopy, an advanced imaging technique, is employed throughout the process to ensure accurate placement of the small needle in relation to the relevant facet. Depending on the patient’s condition, the needle might be inserted at multiple points along the spine.

Post Radiofrequency Ablation

Patients can typically resume their normal activities the day after the procedure, although they might experience mild soreness, numbness, itchiness, or weakness in the treated region for several weeks. Pain relief is generally seen by 3 weeks after the procedure. As with many pain management treatments, the effectiveness of radiofrequency ablation can vary among patients. While the nerves treated do eventually grow back, the procedure generally offers pain relief for several months or even beyond a year.

Risks of a Radiofrequency Ablation

Although the procedure is broadly regarded as safe, it carries inherent risks similar to any procedure. Severe complications such as bleeding, infection and inadvertent nerve damage are exceedingly rare, but they are possible.
