Facet Joint Syndrome

The facet joints are the small, paired joints at the back of each level of your spine that let you bend and twist. Like any joint in the body, they can develop osteoarthritis over time — producing a deep, localized ache that's often worse with standing, walking, or arching the back.

Understanding Facet Joint Syndrome

Every spinal level has a pair of facet joints that guide and limit motion. As the discs between vertebrae lose height with age or injury, more mechanical load gets shifted onto these joints, accelerating wear — much like how a misaligned knee eventually wears unevenly. The result is arthritis-like degeneration that can become a persistent source of pain.

Facet-related pain typically feels like a deep, localized ache near the spine that worsens with extension (arching backward) or rotation, and often eases when sitting or leaning forward — a pattern that can look similar to other causes of back pain but behaves differently on exam.

Care Pathway

How treatment typically progresses

1

Start with Conservative Care

Medications

NSAIDs are typically the first line given their effect on joint inflammation, with acetaminophen as an alternative when NSAIDs aren't well tolerated. Topical NSAID gels can also help for a well-localized facet joint without the systemic side effects of an oral medication.

Physical Therapy & Exercise

Because facet joints load more heavily in extension, effective PT generally emphasizes flexion-biased core stabilization and general mobility work rather than the extension-focused McKenzie protocols sometimes used for disc-related back pain — a good example of why the right exercise approach depends on getting the diagnosis right first.

Activity & Behavior Modifications

Avoiding prolonged standing or walking with an arched lower back, adjusting a mattress or workstation that forces extension, and pacing activities that involve repetitive bending backward all reduce strain on an irritated joint, consistent with first-line, non-invasive management.

If Conservative Care Isn't Enough

Diagnostic Medial Branch Block (MBB)

A diagnostic medial branch block numbs the small nerves supplying the suspected facet joint. Because imaging alone can't confirm the facet joint as the pain source, this block is the deciding step. Learn more on the Medial Branch Blocks (MBB) & Radiofrequency Ablation (RFA) treatment page.

Radiofrequency Ablation (RFA)

If the block gives clear, if temporary, relief, radiofrequency ablation of the same nerves typically extends that relief substantially, with results commonly lasting into the 9 to 18 month range. For most patients, repeating RFA periodically is a perfectly reasonable long-term plan.

Regenerative Treatment: Platelet-Rich Plasma (PRP)

For select patients — particularly those looking to space out repeat ablations — intra-articular PRP is an option worth discussing alongside or in place of a repeat RFA, though the evidence for it here is still less established than for the medial branch block and RFA pathway.

Surgical Endoscopic Rhizotomy (Last Resort)

In rare cases where percutaneous RFA gives real but consistently short-lived relief, Dr. Foster also offers surgical endoscopic rhizotomy — a more permanent procedure that sections the medial branch nerves under direct visualization. It's seldom necessary given how effective and low-risk repeat percutaneous RFA is, but for patients who want a single, more durable solution, it's an option he can perform himself as part of your ongoing care, rather than a referral elsewhere.

This is a logical progression based on your response to each step — not a jump straight to the most invasive option, and not a rigid ladder you have to climb regardless of your diagnosis.

How We Build Your Plan

The clinical reasoning behind this recommendation

1

What's the diagnosis?

A physical exam showing pain reproduced with spinal extension and rotation, correlated with imaging showing facet degeneration at the matching level — but confirmed only by a diagnostic medial branch block, not imaging alone.

2

What's the mechanism?

Facet joints are true synovial joints that can develop osteoarthritis. As discs degenerate and lose height, they transfer more load onto the facets, accelerating that wear and irritating the joint capsule and the small medial branch nerves that carry its pain signal.

3

What are the options?

Activity modification and targeted physical therapy, a diagnostic medial branch block, radiofrequency ablation (RFA) of the medial branches if the block is positive, regenerative treatment for select patients, and — rarely — surgical endoscopic rhizotomy, which Dr. Foster performs himself.

4

Why this approach?

Facet degeneration shows up on imaging in plenty of people with no back pain at all, so a scan showing arthritis doesn't prove it's the cause of your symptoms. The medial branch block is what actually tests whether that specific joint is generating your pain — and it's the same diagnostic step that determines candidacy for RFA.

5

What are the tradeoffs?

Radiofrequency ablation provides substantial, often long-lasting relief, but it isn't a permanent fix — it interrupts the pain signal rather than reversing the arthritis, and relief typically fades as the treated nerves regenerate, at which point the procedure can be repeated.

Prognosis

A condition to manage well, not one that disappears

Facet joint syndrome comes from arthritis-like degeneration in the joint itself, and that underlying wear doesn't reverse — so this is generally a chronic, long-term condition rather than one with a defined cure. The good news is that the pain itself responds very well to treatment: most patients get substantial, repeatable relief from radiofrequency ablation, often maintaining good function for years with simple periodic retreatment rather than an escalating series of procedures, and surgery is rarely needed. It's a condition most patients end up managing quite comfortably over the long run.
