Radiofrequency ablation (RFA) is a minimally invasive procedure for treating pain. It works by destroying the nerve fibers that transmit the pain signals to the brain. RFA can offer lasting relief for those suffering from chronic pain, particularly the neck, lower back, and arthritic joints.
How RFA is done
Patients need to show successful response to trial injections or diagnostics to be the right candidate for RFA. So you may undergo the procedure if you have recurrent pain and have experienced good relief with a nerve block injection. Usually, your doctor will do the necessary tests to help you establish candidature. You may not be an ideal candidate if you have bleeding problems or active infections.
Once you are cleared for the procedure, your doctor will issue an intravenous medication to calm you down. You’ll then be required to lie on your back or stomach on an x-ray table where you get anesthesia to numb the area of your skin before the procedure. Your doctor will then:
- Insert a thin needle into the pain area – he/she may use an x-ray to uncover the exact place
- Place a microelectrode via the needle – he/she will identify the right area by
