Radiofrequency Treatment for Cervical Osteoarthritis (Cervical Facet Joint Denervation)

Pain originating in the facet joints is carried by small nerve fibres called medial branches. Radiofrequency denervation is an interventional treatment that reduces pain transmission by applying controlled heat to these nerves in patients with facet-related pain. The procedure takes place in operating theatre conditions under local anaesthesia; it lasts 20–25 minutes, and the patient walks home the same day. In appropriately selected patients, relief lasts for months; the procedure can be repeated when pain returns.

The Facet Radiofrequency Treatment Process

• Imaging Guidance: The procedure is performed in operating theatre conditions under live X-ray imaging (fluoroscopy); a thin cannula is used to reach the targeted nerve fibre.
• Controlled Heat Technology: A device producing radio waves (radiofrequency) applies controlled heat to the nerve fibre, aiming to reduce transmission through the medial branch carrying the pain signal. Motor nerves supplying the arms are identified and protected using stimulation testing during the procedure.
• Local Anaesthesia and Short Duration: The procedure requires no extensive preparation, is performed under local anaesthesia and takes 20–25 minutes in most patients.
• Rapid Discharge: Patients walk home after a brief observation period. Avoiding heavy physical activity and sudden strain on the neck for the first 24–48 hours is sufficient.

This interventional pain procedure forms part of cervical osteoarthritis treatment for chronic facet-related neck pain; if needed, it can be performed in the same session as an epidural injection. Radiofrequency denervation does not eliminate spinal stenosis or compression of the spinal cord or nerve roots. When pain radiates into the arm and nerve root compression is suspected, treatment is planned according to the approach for cervical spinal stenosis.

Does Cervical Radiofrequency Denervation Relieve Chronic Neck Pain? (Success Rates)

Yes. In appropriately selected patients with facet-related pain, radiofrequency denervation significantly reduces neck pain. In a sham-controlled study, pain took approximately 9 months (263 days) to return to half its original level in the radiofrequency group, compared with 8 days in the sham group [1]. In 61–74% of appropriately selected patients, pain disappeared completely or was substantially reduced for at least 6 months, and patients returned to work [2]; repeating the procedure when pain returns can restore relief [3]. In patients diagnosed by clinical examination, the effect may not be apparent in the first months but can emerge over the longer term [6]; in some patients, the procedure is repeated within 6–12 months [4]. Appropriate patient selection has the greatest influence on the outcome [5].

What Are the Risks of Cervical Radiofrequency Treatment?

Serious complications are rare. Motor nerves supplying the arms are identified and protected by stimulation testing during the procedure; the studies cited above reported no permanent nerve injury or weakness [1, 4]. The most common side effect is temporary numbness in the skin area supplied by the treated nerves; patients experiencing this in the study did not find it troublesome [1]. Temporary skin sensitivity (local neuritis) or muscle pain lasting 1–2 weeks may also occur at the treatment site; these resolve on their own. Infection and bleeding are uncommon; sterile technique and imaging guidance reduce this risk.

🩺 Physician Insight & Clinical Experience

“The mistake I most often see in my patients with cervical osteoarthritis is trying not to move their neck at all because of pain; muscles weaken in an inactive neck, and pain and restricted movement reinforce each other. My aim with radiofrequency is not to destroy the joint itself, but to silence the pain alarm travelling from it to the brain. When I target the nerve precisely under imaging and deliver the radiofrequency current, the patient’s pain decreases substantially. Once pain is relieved, the patient starts moving their neck comfortably and doing their exercises; that is the real benefit.”

Frequently Asked Questions

What Is Cervical Radiofrequency Treatment and How Is It Performed?

It reduces pain transmission by applying controlled heat under fluoroscopic guidance to the medial branch nerves carrying pain signals from the facet joints. The procedure takes place under local anaesthesia and lasts 20–25 minutes.

What Is the Success Rate of Cervical Radiofrequency Treatment?

In approximately two-thirds of appropriately selected patients, pain disappears completely or decreases substantially for at least 6 months [2]; the procedure can be repeated when pain returns [3].

Does Cervical Radiofrequency Treatment Have Risks or Side Effects?

Yes, but serious complications are rare. The most common effects are temporary numbness in the skin area supplied by the treated nerves and skin sensitivity at the treatment site that can last a few weeks; both resolve on their own [1]. Motor nerves supplying the arms are protected by stimulation testing.

Is There a Risk of Paralysis During Radiofrequency Facet Joint Denervation?

No, paralysis is not an expected complication of this procedure. Radiofrequency energy is applied only to the medial branch nerve transmitting pain from the joint; motor nerves supplying the arms are identified and protected by stimulation testing, and the procedure is performed in an operating theatre under live imaging. New weakness or widespread numbness after the procedure requires urgent medical assessment.

Is Rest Necessary After Radiofrequency Treatment?

No prolonged rest is needed; avoiding heavy physical activity and sudden strain on the neck for the first 24–48 hours is sufficient.

Will I Be Asleep During Radiofrequency Treatment, and Is It Painful?

No, you will not be put to sleep. The procedure is performed under local anaesthesia; brief stinging or pressure may be felt when the cannula makes contact, but there is no unbearable pain.

How Many Minutes Does Facet Joint Denervation Take? Can I Go Straight Home?

The procedure takes 20–25 minutes. After a brief observation period, you can walk home the same day.

Which Specialist Performs Radiofrequency Treatment for Cervical Osteoarthritis in Istanbul?

One of the physicians performing radiofrequency treatment for cervical osteoarthritis in Istanbul is Op. Dr. M. Levent Deniz, a specialist in brain, nerve and spine surgery.

How Much Does Radiofrequency Treatment for Cervical Osteoarthritis Cost?

The cost depends on the number of facet joint levels treated, whether a combined injection is needed and hospital conditions; an exact price can only be determined after examination and assessment of imaging.
