Lumbar Osteoarthritis and Facet Syndrome Treatment

What Is Lumbar Osteoarthritis?

Lumbar osteoarthritis (facet syndrome) is wear over time in the facet joints that connect the lower-back vertebrae at the rear of the spine [1]. These small joints connect the five lumbar vertebrae and help the spine move flexibly forwards, backwards and sideways. Osteoarthritis becomes very common with age, reaching 89% in the 60–69 age group; however, no association was found between osteoarthritis seen on imaging and lower-back pain [2]. An imaging finding alone therefore does not show that the joint is the pain source. Facet syndrome, in which degeneration causes clinical pain, is established separately through examination and further assessment.

What Causes Lumbar Osteoarthritis?

The most common cause is age-related wear.

• Repeated mechanical loading
• Excess weight
• Previous lower-back injuries
• Physically demanding work or uncontrolled lifting (it can also occur in younger people)

What Are the Symptoms of Lumbar Osteoarthritis?

The most typical symptom is morning stiffness.

• Morning Stiffness: Intense stiffness, a feeling of being “rusty” and difficulty moving the lower back at the start of the day.
• Pain When Leaning Backwards: Increased severe pain from joint compression when extending the trunk backwards.
• Referred Pain: Pain spreading to the buttock and back of the thigh, but usually not below the knee or to the toes.
• A Cycle of Inactivity: Pain reduces movement, which weakens muscles and worsens symptoms.

How Is Lumbar Osteoarthritis Diagnosed?

Lumbar osteoarthritis is recognised through the patient’s history and examination; MRI, X-rays and a diagnostic block establish the diagnosis. The examination looks for tenderness and pain over the facet joints during backward bending (extension) or rotation. Standing lumbar X-rays show joint-space narrowing and bony outgrowths (osteophytes). Lumbar MRI is requested to assess associated problems such as disc degeneration and thickening of the ligament within the spinal canal (ligamentum flavum). In uncertain cases, substantial pain relief after an image-guided diagnostic facet block (temporary numbing test) supports the joint as the pain source and guides treatment.

How Does Lumbar Osteoarthritis Improve?

Pain improves with non-surgical methods in most patients. Exercise and physiotherapy come first; radiofrequency treatment (facet joint denervation) is added for patients whose pain comes from the facet joint.

• First Stage (Pain Relief): International guidelines recommend a stepwise approach: exercise and physiotherapy first; if pain appears facet-related, a diagnostic facet block is performed, and facet joint denervation (radiofrequency treatment) is considered as an algology procedure (interventional pain treatment) in patients responding well [4]. Radiofrequency reduces pain for up to 12 months in suitable patients [3].
• Second Stage (Patient Education and Protection): This is at least as important as the first. Once pain has eased, patients receive a personalised exercise programme to prevent further joint wear and learn which daily behaviours support healthy spinal structure and which to avoid.

🩺 Physician’s Insight & Clinical Experience

“The most common misconception I encounter in patients with lumbar osteoarthritis is treating the degeneration seen on imaging as the sole explanation for their pain and accepting it as an inevitable part of ageing. What really matters is establishing with a diagnostic block whether the pain actually comes from the facet joint. Radiofrequency denervation can provide meaningful relief in patients selected accordingly. The regular exercise habit we help patients build during this process is at least as important as interventional treatment; strong back and abdominal muscles help reduce the load on the facet joints.”

Frequently Asked Questions

What Happens If Lumbar Osteoarthritis Is Not Treated?

Degeneration progresses over time and bony spurs (osteophytes) develop, contributing to canal narrowing in some patients. Reduced movement due to pain also weakens the lower back muscles, creating a cycle of worsening symptoms.

Can Lumbar Osteoarthritis Be Treated Without Surgery?

Yes, non-surgical methods are the first choice: treatment starts with physiotherapy and exercise. If the pain appears facet-related, a diagnostic facet block is performed, followed by radiofrequency denervation in patients with a good response.

Are Morning Lower Back Stiffness and Pain Signs of Osteoarthritis?

Yes, morning stiffness is the most typical feature of facet syndrome: a “rusty” feeling on waking that eases with movement within 15–20 minutes. However, this alone does not establish the diagnosis; similar symptoms occur in other spinal conditions.

When Does Lumbar Osteoarthritis (Facet Disease) Require Surgery?

Surgery is considered if degenerative changes compress nerves and cause weakness or a marked limitation of walking distance (spinal stenosis), or if spondylolisthesis also occurs and symptoms progress despite non-surgical treatment. Decompression without screws or stabilisation with screws is then assessed.

Can Lumbar Osteoarthritis Cause Pain Radiating to the Legs?

Yes, but it differs from disc-herniation pain. Facet-related “referred pain” spreads to the buttock and back of the thigh, rarely extends below the knee and does not follow a specific nerve pathway. Pain extending below the knee to the calf and toes with numbness suggests an accompanying lumbar disc herniation.

Which Doctor Treats Lumbar Osteoarthritis?

Neurosurgery, physical medicine and rehabilitation, and algology (interventional pain treatment) specialists treat lumbar osteoarthritis.

Which Specialist Treats Lumbar Osteoarthritis in Istanbul?

One of the physicians treating lumbar osteoarthritis in Istanbul is M. Levent Deniz, MD, a specialist in neurosurgery.

How Much Does Lumbar Osteoarthritis Treatment 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.
