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.
