Overview
what it is and why it mattersFacet joint arthropathy is degenerative arthritis affecting the zygapophyseal (facet) joints of the spine, which guide and limit spinal motion at each level. Like any synovial joint, facets can develop cartilage loss, osteophyte formation, joint space narrowing, and synovitis. It is an extremely common cause of axial neck or back pain — especially in older adults.
Facet-mediated pain is typically worse with extension and rotation, eased by forward flexion, and may radiate to the shoulder or buttock (referred pain, not radiculopathy). The diagnosis is confirmed by response to medial branch nerve blocks.
Diagnosis
exam first, imaging secondX-rays and CT show facet joint hypertrophy and sclerosis. MRI demonstrates synovial cysts and ligamentum flavum thickening. However, imaging findings do not reliably predict who has facet pain — diagnostic medial branch nerve blocks (controlled, fluoroscopy-guided) are the gold standard for confirming facet-mediated pain before ablation.
Treatment Path
how care progresses at OSIPhysical therapy
Extension and rotation exercises, core stabilization.
NSAIDs
For acute flares.
Facet intra-articular injection
Corticosteroid injected into the facet joint.
Medial branch nerve block
Diagnostic local anesthetic block; if two controlled blocks give >80% relief, the patient is a candidate for ablation.
Radiofrequency ablation (RFA)
The medial branch nerves supplying the arthritic facets are ablated with radiofrequency energy, providing 12–18+ months of relief. Repeatable as nerves regenerate.
If Surgery Is Truly Needed
rare for most patientsSurgery helps only a small minority of spine patients — usually those with a specific structural problem plus a nerve issue that isn’t getting better with a structured non-operative trial. When that step is genuinely warranted, OSI coordinates it the same way we coordinate every other part of your care: imaging, records, and the handoff are handled for you, so no part of the process falls on your shoulders.
