Radiofrequency Ablation
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.
