Radiofrequency Treatment for Lumbar Osteoarthritis (Facet Joint Denervation)

Radiofrequency treatment (facet joint denervation) uses imaging-guided heat to block the pain-transmitting nerve in chronic facet-joint-related lower back pain. No incision is made; it is performed under local anaesthesia and takes 20–30 minutes. Success depends on confirming with a diagnostic block that the pain truly originates in the facet joint.

What Is Radiofrequency Treatment, and How Does It Work?

Radiofrequency treatment (facet joint denervation) is an interventional pain procedure used for chronic facet-joint-related lower back pain [2].

• Mechanism: The nerve carrying pain signals from the facet joints to the brain is called the medial branch. In patients whose diagnostic medial branch block supports a facet origin for their pain, a computer-controlled device applies heat to this nerve, creating a small thermal lesion that reduces pain transmission.
• Application: It is performed in an operating theatre under fluoroscopic (real-time imaging) guidance.

The procedure is used for pain from facet syndrome (lumbar osteoarthritis) and for facet-related pain accompanying spinal stenosis, together with an epidural injection when necessary. Radiofrequency does not widen the canal; in stenosis it targets only the accompanying facet-related pain.

The Procedure

• Preparation and Anaesthesia: No extensive preparation is required. It is performed entirely under local anaesthesia without putting the patient to sleep.
• Duration: Depending on the number of levels and sides treated, it takes 20–30 minutes.
• Discharge: After approximately 1–2 hours of observation, our patients walk home the same day. Avoiding heavy exertion for the first 24–48 hours is sufficient; bed rest is unnecessary.

Does Radiofrequency Denervation Relieve Lower Back Pain? (Success Rates)

Yes, in correctly selected patients, it provides lasting pain control. In the reference study, 87% of patients selected by diagnostic medial branch block reported at least 60% pain reduction for 12 months, and 60% reported at least 90% reduction [1]. These figures apply to patients selected through a diagnostic block. In good responders to the block, pain reduction lasts up to 12 months [2]; the effect has also been shown not to be attributable to placebo [3]. Radiofrequency was superior to placebo in the short, medium and long term [5].

Success depends on patient selection: effects are more pronounced in those responding well to a diagnostic block [2, 4], while a broad review found the average effect small [7]. Favourable results have been reported in block-selected patients [8].

Is Radiofrequency Denervation Safe? (Risks and Side Effects)

Yes, when performed under fluoroscopic guidance with appropriate technique, it has a low complication rate. Sensory nerves are targeted, while motor nerves are protected through nerve stimulation testing, so serious neurological complications are rare. A safety study examining 616 lesion sites in 116 procedures found a minor complication rate of 1.0% per lesion: pain at the treated site lasting more than two weeks and nerve-related pain lasting less than two weeks. No infections, new weakness or new sensory loss occurred [6].

🩺 Physician’s Insight & Clinical Experience

“As a surgeon who frequently uses radiofrequency treatment, I can say that it gives very good results in the right patient. The main cause of unsuccessful outcomes is an incorrect diagnosis. Symptoms of other conditions, particularly spondylolisthesis, can closely resemble facet disease. Success therefore depends on careful patient selection and a diagnostic block before the procedure.”

Frequently Asked Questions

What Is Radiofrequency Treatment, and How Is It Performed?

It is an incision-free procedure that reduces pain transmission by applying heat to the facet joint’s pain nerve under fluoroscopic guidance; it takes 20–30 minutes.

What Is Its Success Rate?

Of patients selected through a diagnostic block, 87% reported at least 60% pain reduction for 12 months [1]. Success depends on selection, with a more pronounced effect in good responders to the block [2, 4].

Does It Have Risks or Side Effects?

Yes, but they are low: a safety study found a 1.0% minor complication rate per lesion and no infection or new nerve injury [6]. Temporary pain at the treatment site is most common; motor nerves are protected using stimulation testing.

Is Rest Needed, and When Can I Return to Work?

Avoiding heavy exertion on the day of treatment and the following day is sufficient. With no incision or stitches, our patients return to work and daily life within 1–2 days; bed rest is not needed.

What Is the Diagnostic Block (Test Injection) Before Treatment?

It is the most important preliminary step. Before radiofrequency, a very small amount of local anaesthetic is injected beside the pain-carrying medial branch nerve (medial branch block) to test whether the joint is the source. If pain temporarily improves substantially, radiofrequency is considered likely to succeed.

When Does Radiofrequency Treatment Take Effect?

The effect usually becomes clear within 2–3 weeks. Some patients improve immediately; temporary pain at the treatment site may obscure the result during the first days.

How Does Radiofrequency Facet Denervation Differ from Laser Treatment?

They target different problems: radiofrequency targets the facet joint’s pain nerve, while laser is applied to the disc in selected disc conditions. They are therefore not alternatives to one another.

Can Radiofrequency Also Be Used for Cervical Osteoarthritis?

Yes, it is also used for chronic neck pain originating in the cervical facet joints. Because cervical anatomy differs, patient selection and technique are assessed separately.

Which Specialist Performs Radiofrequency Treatment (Facet Denervation) in Istanbul?

One of the physicians performing radiofrequency treatment (facet joint denervation) in Istanbul is M. Levent Deniz, MD, a specialist in brain, nerve and spine surgery.

How Much Does Radiofrequency Treatment (Facet Denervation) Cost?

As treatment costs vary according to the patient and hospital conditions, a definite fee can only be determined after examination and review of imaging.
