Radiofrequency Ablation – RFA

Radiofrequency Ablation – RFA

Radiofrequency ablation or RFA is a minimally invasive technique to treat chronic back and neck pain. Radiofrequency ablation can disable nerve fibers that are carrying the pain signal through the spinal cord to the brain. In the right patients, about 80-90% of RFA procedures provide adequate pain relief that lasts for a year or more. The technique may be useful for some people living with chronic arthritis or degenerative back and neck problems.

RFA Procedure

The procedure is similar to a needle biopsy and involves inserting a needle-like probe into the body. Radiofrequency waves are sent out from the probe into the surrounding tissue, which causes the nearby cells or nerves to die.

To place the tip of the probe in the correct location, the health care provider uses fluoroscope or ultrasound.

Radiofrequency ablation can take place in an office or outpatient setting and requires no general anesthesia. You may get medicine to help you relax for the procedure, as well as local anesthetic agent for the area of the skin where the probe is inserted.

Most people undergoing radiofrequency ablation can go home the same day as their treatment and can return to their normal activities within 24 hours.

Risks and Complications of Radiofrequency Ablation

In general, RFA may have lower risks than open surgery. The chief concern is bleeding or infection where the probe in inserted into the body, but this is a rare occurrence. Some people experience temporary weakness or numbness or swelling or bruising at the insertion site.
