Radiofrequency Ablation (RFA)

Radiofrequency Ablation (RFA) is a procedure that is designed to provide longer term pain relief than which is provided by simple injections or nerve blocks.

We are welcoming new patients that have been involved in auto, motorcycle, bicycle or pedestrian auto accidents

Radiofrequency ablation/lesioning is a process used to provide longer term pain relief than that provided by simple injections or nerve blocks. Many patients who are being considered for RFA have already undergone simple injection techniques like Epidural Steroid Injections (ESI), Facet Joint Injections (Medial Branch Blocks), or other nerve blocks with pain relief that was less prolonged than desired. By selectively destroying nerves that are carrying pain impulses, the painful structure can be effectively denervated and the pain reduced or eliminated for anywhere from a few months up to 12 months.

Once the structure has been determined to be a pain generator (through previous pain injections), its nerve supply is targeted for interruption. A small insulated needle or RF cannula is positioned next to the nerves with fluoroscopy guidance (live x-ray). The shaft of the cannula is covered with a protective insulation so that the current only passes through the very tip. A local anesthetic is then injected to numb the area. The RF generator is then used to heat the cannula tip for up to 90 seconds, and the target nerve is destroyed.

The procedure itself is no more painful than other injection procedures. It is quite common for neck or back pain to increase for a few days or longer after the RF procedure before it starts to improve.

You will be monitored for up to 30 minutes after the RFA. When you are ready to leave, the staff will give you discharge instructions. Take it easy for the rest of the day. You may feel sore for one to four days. It may be due to muscle and nerve irritation. Maximum pain relief normally comes in two to three weeks but can take as long as six to eight weeks.
