Radiofrequency Ablation, or RFA, uses radiofrequency to disrupt nerve signals. This procedure is performed to prevent a nerve from transmitting pain signals from an injury.
During the Procedure
First, a physician will numb the area of the injection with a local anesthetic. A contrast dye is then injected, allowing guidance of the needle using fluoroscopy. The physician will then position the needle at the proper nerve. Once the physician properly places the needle at the nerve, an anesthetic is administered, and radiofrequency energy is released into the nerve, disrupting nerve signals.
After the Procedure
After the procedure, expect to be monitored for about 30 minutes. You will be instructed to rest the day following the procedure. Full pain relief is expected after a few weeks.
