Radiofrequency ablation sounds like it could be a space-age weapon of war, but it’s actually just a complicated name for a simple procedure. Also known as RFA, radiofrequency ablation is a treatment method physicians use to treat symptoms of arthritis and other types of joint pain. The experts here at Comprehensive Pain & Neurology Center use RFA treatment for patients with chronic low back pain related to joint arthritis.
How does radiofrequency ablation work?
In RFA therapy, a radiowave produces a current to heat nerve tissue. The current heats up a targeted section of the nerve tissue, which decreases its ability to transmit pain signals. Patients with long-lasting pain due to arthritis are good candidates for RFA therapy.
Arthritis causes joints in the body to degenerate, making movement extremely painful. Radiofrequency ablation “numbs” the brain’s ability to sense that pain because it decreases the signals coming from the nerves. You will be given local anesthesia during treatment, which keeps you awake but unable to feel pain. Then, the doctor will use an X-ray machine to guide the needle to the affected area. A microelectrode inserted through the needle will deliver the radiofrequency current. You will feel minimal heat or discomfort during this process.
Is RFA therapy safe?
RFA therapy is indeed safe. It’s also well-tolerated in most cases. Other than a very slight chance of infection or bleeding at the injection site, there are no risks associated with RFA treatment. Side effects are very mild and include minor discomfort and/or swelling and bruising around the treatment area.
If you do experience these side effects, they will generally dissipate in a day or two. There are a small number of people for whom RFA is not appropriate. People who have current infections or a history of bleeding problems should not undergo RFA treatment. An expert at Comprehensive Pain & Neurology Center will be able to tell you if RFA is a good choice for you.
What can I expect after treatment?
For such small risks, RFA therapy offers a great outcome. Depending on the cause and location of your pain, relief from RFA treatment can last anywhere from nine to 24 months. Occasionally, patients will report that the relief lasts for several years. After treatment, you will need someone to drive you home and you should not drive or operate machinery for the next 24 hours due to the sedation given prior to the procedure. You will also be encouraged to take it easy and avoid engaging in strenuous activities for the next few days.
