Facet Joint Syndrome.
What is facet joint syndrome?
Facet joints — also called zygapophyseal joints — are the paired synovial joints connecting each vertebra to the one above and below it at the back of the spine. They guide and limit spinal movement at each level, and like all synovial joints they are lined with cartilage, enclosed by a capsule, and richly innervated — making them a significant and well-documented source of pain when they become irritated, inflamed or degenerated.
Facet joint syndrome refers to pain arising from these joints, most commonly in the lumbar spine. Research using controlled diagnostic medial branch nerve blocks — the gold-standard diagnostic technique — estimates that lumbar facet joints account for approximately 15 to 45% of chronic lower back pain in adults, making them one of the most prevalent structural sources of spinal pain. For cervical facet joint syndrome — the neck equivalent — see our dedicated cervical facet joint syndrome page.
What causes lumbar facet joint syndrome?
The most common cause is age-related degeneration — the facet joint cartilage gradually thins and deteriorates, osteophytes (bone spurs) form around the joint margins, and the joint capsule thickens and becomes fibrotic. This process mirrors osteoarthritis in other synovial joints and accelerates with age, prior injury and sustained postural loading.
Poor posture, particularly prolonged extension postures or repetitive twisting movements, can stress the facet joints and contribute to syndrome development. Jobs and activities involving sustained lumbar extension — heavy manual work, prolonged standing, overhead work — are associated with higher rates of facet-sourced back pain. Spondylolisthesis — where one vertebra slips forward on the one below — places sustained asymmetric loading on the facet joints and is a common associated finding.
Acute facet joint injury — from a sudden twisting or hyperextension force — can produce an acute inflammatory response in the joint capsule that causes the characteristic sudden onset of severe back pain and muscle spasm. This acute presentation, sometimes called a "locked back" or acute facet lock, is among the most common reasons for sudden-onset severe back pain in active adults.
What are the symptoms?
The characteristic symptom is lower back pain that is worse with extension — bending backward — and rotation, particularly combined extension and rotation toward the painful side, which compresses the ipsilateral facet joint. This is the key feature that distinguishes facet-sourced pain from lumbar disc herniation, where flexion is typically more aggravating.
Pain is usually localised in the lower back and may radiate into the buttocks, hips and thighs — a referral pattern that is frequently mistaken for sciatica. Importantly, true facet referral rarely extends below the knee, while sciatic nerve pain from disc herniation typically radiates into the calf and foot with associated neurological symptoms. Stiffness on waking that eases with movement, and difficulty straightening up from a flexed position, are characteristic features of facet joint syndrome.
How is it diagnosed?
Diagnosis involves a combination of clinical assessment, medical history and imaging studies. X-ray and MRI can reveal signs of facet joint degeneration and other structural changes. However, as with most spinal conditions, imaging findings of facet degeneration are extremely common in asymptomatic adults and must be correlated with clinical findings — the presence of facet joint changes on MRI does not confirm they are the source of the patient's pain.
Clinical assessment identifies the most likely pain source through specific provocation testing, palpation of the posterior spinal joints, and assessment of the movement pattern that aggravates and relieves symptoms. Definitive diagnosis, when required for treatment planning, involves medial branch nerve blocks performed by a pain specialist or anaesthetist.
How can physiotherapy help?
Physiotherapy can be an effective and important part of the treatment plan for individuals with facet joint syndrome, providing targeted interventions to help manage pain, improve mobility and enhance overall spinal function.
Manual therapy is the most evidence-based short-term intervention for facet joint syndrome — specifically lumbar joint mobilisation targeting the restricted or painful segments. Mobilisation reduces pain through neurophysiological mechanisms, improves segmental mobility, and normalises the movement pattern that the painful joint has disrupted. In acute facet lock presentations, gentle mobilisation or manipulation — when clinically appropriate — can produce rapid relief of the acute muscle spasm and restore movement far more quickly than rest alone.
Deep stabilising muscle retraining — specifically the multifidus and transversus abdominis — is central to the long-term management of facet joint syndrome. Strengthening the muscles that support the spine, particularly the core and paraspinal muscles, helps stabilise the spine and reduce stress on the facet joints. These muscles are consistently inhibited in people with chronic back pain, and their rehabilitation significantly reduces pain and recurrence. Real time ultrasound guides this retraining by providing direct visualisation of the deep muscles, making their activation teachable in a way that verbal instruction alone cannot achieve.
Hip and gluteal strengthening is equally important — the gluteal muscles are the primary load-sharing partners of the lumbar spine, and their weakness forces the lumbar facet joints to absorb load that the hip musculature should be managing.
Clinical Pilates is an excellent environment for facet joint syndrome rehabilitation — providing structured core and gluteal strengthening with emphasis on spinal alignment and movement quality. Dry needling of the lumbar multifidus and erector spinae assists with pain management and muscle relaxation, particularly during acute flare-ups where guarding is limiting mobility work.
Posture and body mechanics education — teaching patients how to maintain proper posture and move in ways that reduce stress on the facet joints — is an important component of long-term management. Ergonomic assessment of workstation, driving posture and lifting mechanics addresses the environmental contributors that will perpetuate the problem if not modified alongside the clinical treatment.
For patients whose facet joint syndrome developed following a workplace injury or motor vehicle accident, WorkCover and CTP funded physiotherapy is available.
