What is Radiofrequency Ablation (RFA)?

Radiofrequency ablation, or rhizotomy, is a safe, effective, and minimally invasive procedure aimed at relieving chronic pain. During an RFA procedure, heat from an electrical current is used to decrease pain signals in the affected area. Radiofrequency nerve ablation can help treat patients who suffer from chronic back, neck, and joint pain, especially when pain medication, physical therapy, or other treatment options have proven unsuccessful at doing so. While the duration of pain relief from RFA can vary, many patients have experienced pain relief for 6 to 12 months after treatment.

What Does Radiofrequency Ablation Treat?

Radiofrequency ablation has proven to be successful at managing lower back and neck pain that has not responded to other treatment options. It also helps manage pain related to degenerative joint diseases, such as arthritis. If you’re suffering from chronic pain in your back, neck, or joints, RFA may be a viable treatment option for you.

What to Expect from Radiofrequency Ablation

If you’re deemed to be a good candidate for radiofrequency ablation, our Austin pain specialists will inform you of any precautions that should be taken to prepare for your RFA procedure. Some of these precautions may include fasting or adjusting insulin dosage (if you have diabetes) prior to your procedure and arranging for someone to drive you home after treatment.

During the actual RFA procedure, patients can expect to receive a local anesthetic to numb the treatment area. The doctor will then insert a thin needle into your skin, using a live X-ray to help pinpoint the area where you feel pain. A microelectrode will then be inserted through the needle, sending a safe electric current that heats your nerve tissue and decreases pain signals. This process is then repeated until the nerves in the area where you feel pain have been disrupted to no longer transmit pain signals.

Types of Radiofrequency Ablation Procedures

Continuous Radiofrequency Ablation

Continuous radiofrequency ablation involves gradually increasing the temperature of the microelectrode used to heat the nerve tissue. The heat is maintained for 90 to 120 seconds, which is the time needed to disrupt the nerve’s ability to transmit pain signals. The duration of a continuous RFA procedure will vary depending on the amount of nerves that need to be treated to manage the patient’s pain.

Pulsed Radiofrequency Ablation

Pulsed radiofrequency ablation consists of quick, high voltage currents that last less than half a second. The pulsing currents are maintained until the nerve tissue is disrupted, which can take anywhere from two to eight minutes.

Initial Evaluation

During your initial appointment, our pain specialists will take the time to learn about your chronic pain and any past treatment attempts. This evaluation will help us determine a tailored treatment option that will work for you.


Receive Your RFA Treatment

Patients will be given a local anesthetic to numb the treatment area. The doctor will then insert a thin needle to the area suffering from pain, sending a small electric current to heat your nerve tissue and decrease pain signals.


Short Recovery

While patients can walk on their own after their RFA procedure, driving and engaging in rigorous activity should be avoided for 24 hours. Patients can resume their normal activities after this time period.
