Radiofrequency Thermocoagulation (RFTC)

Radiofrequency thermocoagulation (RFTC) is a minimally invasive outpatient procedure used to provide pain relief by utilizing radio waves and heat to destroy targeted nerves, specifically in the case of facet joint pain. This technique has also been successfully employed for treating fast heartbeats and tumors.

The Actual Procedure

RFTC is performed under local anesthesia in an outpatient setting. Intravenous sedation is administered to help the patient relax. During the procedure, a specialized needle is carefully placed into the facet joint under the guidance of X-ray imaging. Radiofrequency waves are then delivered through the needle’s tip, generating heat that coagulates the nerve and renders it unable to transmit pain signals, effectively providing relief.

Post-Procedure and Recovery

Following the RFTC procedure, the patient is taken to a recovery room for a brief monitoring period and given post-procedure instructions before being discharged.

Risks and Complications

RFTC is considered a safe, non-surgical treatment option with minimal risk of complications. While there are potential risks associated with the procedure, they are generally low. Your doctor will discuss the procedure in detail, including the risks involved, and address any questions or concerns you may have.

After the Injection

It is common to experience an initial increase in pain and/or muscle spasms for several days after the procedure. Additional pain medications or muscle relaxants may be prescribed to ensure your comfort.

Swelling and bruising at the needle insertion sites may occur but can be alleviated using cold packs.

You will be provided with an instruction sheet outlining what to do and who to contact in case of any questions or concerns.

Follow-Up and Long-Term Relief

Your doctor will schedule a follow-up appointment or phone consultation within three to four weeks after the RFTC procedure to evaluate your progress.

The degree of pain relief may vary from person to person, with maximum pain reduction typically occurring within three or more weeks. It is common to experience 50 percent or greater pain relief. The duration of pain relief can range from six to 12 months or even longer. While nerve regeneration may occur over time, resulting in pain recurrence, the procedure can be repeated if necessary.

The Importance of Rehabilitation

Rehabilitation plays a crucial role in maximizing the benefits of RFTC. Starting a program of conditioning, strengthening, and range of motion exercises after the procedure is recommended. By enhancing muscle strength around the affected joints, pain relief may be more prolonged following radiofrequency ablation. Rehabilitation also helps mitigate the intensity of pain when nerves regenerate.
