Radiofrequency Denervation (RFA) for Facet Joint Pain in Dubai

What Is Facet Joint Pain and Why Is It So Often Missed?

Facet joint pain refers to discomfort arising from the small paired joints that connect the vertebrae at the back of the spine. These joints, known medically as zygapophyseal joints, are present at every spinal level from the neck to the lower back. Their role is to guide and limit spinal movement while providing stability as you bend, rotate, and extend.

When these joints become worn, inflamed, or arthritic, they can become a significant and persistent source of pain. What makes facet joint pain particularly difficult to identify is that it does not usually follow the clear nerve radiation pattern associated with a disc herniation. It tends to produce a deep ache localised to the neck or back, sometimes referring into the shoulders, buttocks, or hips without the telltale leg or arm shooting pain that points unmistakably to nerve compression.

As a result, many patients go undiagnosed for months or longer. They are told their scans look relatively normal, or that no specific cause can be identified, when in fact their facet joints are the primary source of ongoing daily discomfort. For patients in the UAE seeking clarity after a long period of unexplained spinal pain, a structured diagnostic approach is the only way to confirm or exclude the facet joints as the problem.

Dr. Sherief Elsayed, a UK-trained Consultant Spinal Surgeon, FRCS (Tr & Orth), uses a two-stage process to do exactly that.

What Causes Facet Joints to Become Painful?

Facet joint pain is rarely the result of a single event. It typically develops over time and is influenced by a combination of structural, mechanical, and lifestyle factors.

Common causes include:

• Age-related wear and arthritis within the joint surfaces
• Disc height loss at the same spinal level, which forces the facet joints to carry a disproportionate share of the load
• Repetitive mechanical stress from sustained poor posture, prolonged sitting, or heavy physical work
• Whiplash injuries or road traffic accidents, which are a frequent cause of cervical facet joint damage
• Spinal instability or hypermobility at a particular segment
• Post-surgical changes at segments adjacent to a prior fusion

How patients typically describe the pain:

• A persistent deep ache in the neck or lower back
• Stiffness that is worst on waking or after sitting for an extended period
• Pain that worsens when bending backwards or rotating the spine
• Tenderness when pressing directly over the affected spinal level
• Referred discomfort into the buttocks or down the upper thigh (lumbar) or into the shoulders and upper arms (cervical), without the sharpness or electrical quality of nerve root pain

How Is Facet Joint Pain Diagnosed?

Imaging alone cannot confirm facet joint pain: wear in the facet joints is common on the MRI scans of people with no pain. The test is a medial branch block (local anaesthetic on the small nerves to the joint) or a facet joint injection: if your usual pain eases substantially while the anaesthetic works, the facet joints are the likely source, and if it does not, other structures are looked at instead. Read more about facet joint injections and medial branch blocks.

What Is Facet Joint Denervation?

Once the facet joints have been confirmed as the pain source through a positive diagnostic injection, the next option Dr. Sherief Elsayed offers is facet joint denervation.

Facet joint denervation, also known as radiofrequency ablation (RFA) or medial branch neurotomy, is a minimally invasive procedure that interrupts the nerve supply to the painful facet joint. It does not remove the joint or alter its structure in any way. It prevents the joint from continuing to send pain signals to the brain.

Dr. Sherief Elsayed describes what this involves:

“I’ve confirmed that his facet joints are the problem. So the next thing I’ve offered him is a facet joint denervation. What that means is it is also an injection, but I have passed an electric current down onto the facet joint which disrupts its nerve supply, stops sending pain signals up to the brain.”

The procedure step by step:

1. The patient lies comfortably on a procedure table with fluoroscopic imaging available
2. A fine needle is positioned precisely at the medial branch nerve, the small nerve that carries pain signals from the facet joint to the brain
3. A radiofrequency current is passed through the needle, heating the tip to a carefully controlled temperature
4. This heat disrupts the nerve tissue and stops it from transmitting pain
5. The process is repeated at each level where diagnostic injections have confirmed symptomatic facet joints

The procedure is performed under local anaesthetic; light sedation is available on request. Most patients go home the same day.

What Results Can Patients Realistically Expect?

Results from facet joint denervation are measured primarily by how long patients remain free of their previous pain and how significantly their daily function improves.

What the published evidence shows:

• International guidelines conclude that RFA may benefit well-selected people after a positive medial branch block (Cohen 2020; Hurley 2022), but the research is mixed
• Relief usually starts within 1 to 3 weeks
• Relief is not permanent, because the nerves regrow. In studies of neck RFA, the median time before pain returned was 6 to 14 months (Hurley 2022)
• Because the medial branch nerve can slowly regenerate over time, the procedure can be safely repeated if symptoms return
• Results are most durable when patients use the pain-free window to engage in physiotherapy and address the postural and lifestyle factors that stress the facet joints

It is important to be clear about what denervation does and does not do. It does not cure the underlying arthritis or reverse the wear in the facet joint. It can stop pain signals from that joint for a period, which allows patients to rehabilitate, return to normal function, and improve their quality of life without being limited by constant pain.

How Does This Fit Into a Conservative-First Treatment Philosophy?

Facet joint denervation sits within a broader treatment philosophy that Dr. Sherief Elsayed applies consistently. It is not a first-line response to back pain. It is a targeted intervention offered after a structured conservative phase has not provided adequate relief and after diagnostic confirmation has identified the specific pain source.

The typical pathway looks like this:

1. Clinical assessment, including a full history and physical examination
2. Appropriate imaging to exclude other significant structural problems
3. A structured course of physiotherapy, activity modification, and anti-inflammatory treatment
4. If insufficient relief: diagnostic facet joint injection to confirm or exclude the joints as the pain source
5. If diagnostic injection confirms facet involvement and provides temporary relief: radiofrequency denervation
6. Ongoing physiotherapy following denervation to consolidate the benefit and address underlying mechanical factors

This step-by-step approach reflects the principle that pain is a symptom requiring a confirmed diagnosis, not a target to be guessed at. To seek this kind of structured assessment, patients in the UAE can consult a UAE Spine Surgeon who follows a root-cause diagnostic pathway.

Is Facet Joint Denervation Safe?

Facet joint denervation has a well-established safety profile when performed by an experienced spine surgeon using image guidance. Serious complications are uncommon.

What patients should know:

• Temporary soreness at the injection site is normal for a few days after the procedure
• Some patients experience a brief increase in pain in the first one to two weeks as the nerve responds to the thermal treatment; this typically settles
• In rare cases, temporary altered sensation near the treated area may occur
• The procedure does not affect the structural stability of the spine or the function of surrounding nerves that control movement

Patients on blood-thinning medication, with active local infection, or with certain systemic conditions will require an individual assessment before proceeding. Dr. Sherief Elsayed reviews each patient’s full health profile as part of the consultation process.

Facet Joint Pain and Life in the UAE

Several patterns of daily life in Dubai and across the UAE place consistent stress on the facet joints and make this a commonly encountered presentation in clinical practice.

Long periods of driving: Dubai’s road infrastructure means many residents spend considerable time seated behind the wheel. Sustained driving posture, particularly with lumbar flexion and the vibration of the road, loads the facet joints without recovery time.

Extended desk work: Office environments, laptop use on low surfaces, and screens positioned below eye level all promote a forward head posture that chronically overloads the cervical facet joints. Patients who spend eight to ten hours seated in this position daily are placing their neck joints under continuous stress.

High-impact gym training: Extension-loaded movements such as heavy deadlifts, overhead pressing, and hyperextension exercises can aggravate already sensitised lumbar facet joints.

Road traffic accidents: Rear-end collisions and sudden deceleration injuries are a well-recognised cause of cervical facet joint damage. Many patients who present with persistent neck pain months after such an incident have ongoing facet joint involvement that has not been identified or properly treated.
