Typically, RFA is performed after steroid, epidural, or other injection treatments are tried in the sacroiliac or facet joint’s nerves for treating pain symptoms. When Radiofrequency Ablation Is Considered The magnitudes of the heat lesions depend on the temperature and size of the needle, as well as the duration of the procedure. All three types of RFA are used to treat facet and sacroiliac joint pain.

4ĬRF and PRF produce well defined small lesions, while WCRF produces larger lesions involving larger tissue areas.

The water allows a regulated flow of current and also prevents the needle tip from being over-heated. Water-cooled radiofrequency (WCRF) ablation uses a specialized needle that is heated up to 140 degrees Fahrenheit but also cooled by a continuous flow of water.The needle is heated to approximately 107 degrees Fahrenheit in PRF. Pulsed radiofrequency (PRF) ablation uses a needle that delivers short bursts of high-voltage current with silent phases in between when no current is passed.The tip of the needle is heated between 140 to 176 degrees Fahrenheit. Conventional continuous radiofrequency (CRF) ablation uses a needle that delivers continuous high-voltage current to produce a heat lesion.Three types or variations of RFA may be used to produce heat lesions on tissues and are discussed below.

See Lower Back Pain Symptoms, Diagnosis, and TreatmentĮven if the pain is not completely eliminated, RFA may provide moderate pain-relief and restoration of function for daily movements.

Avoid or delay surgery, which could carry additional risks and a long recovery period.

Reduce the intake of pain medications, which tend to have serious side effects or risks when used long term.

Improve neck and back function for more range of motion, which may allow the patient to continue with a physical therapy program.

Reduce neck or back pain for longer periods of time, typically for more than 6 months.

The goals of treating facet and sacroiliac joints with RFA are to: This resulting lesion prevents the nerve from sending pain signals to the brain. RFA involves heating a part of the pain-transmitting nerve with a radiofrequency needle to create a heat lesion. Watch: Lumbar Radiofrequency Neurotomy Video In RFA, a small amount of electrical current is carefully passed through a specialized radiofrequency needle on a pain-transmitting nerve to create a heat lesion.
