Understanding Facet Joint Arthropathy
Facet joint arthropathy refers to degeneration or arthritis of the small paired joints located at the back of each vertebra, which guide and stabilize spinal movement.
These joints are subject to significant repetitive stress over a lifetime, making facet joint arthropathy a common source of localized back or neck pain, particularly with movements such as extension and rotation.
What Causes Facet Joint Arthropathy?
- Age-related cartilage wear within the facet joints
- Cumulative mechanical stress from repetitive spinal movement
- Previous spinal injury altering joint loading patterns
- Adjacent disc degeneration increasing stress transferred to the facet joints
Symptoms
- Localized back or neck pain, often worse with extension or twisting movements
- Stiffness that may be more noticeable in the morning
- Pain that can radiate to the buttock or thigh in lumbar facet arthropathy, though typically not as far as true sciatica
- Discomfort that eases with rest and flexion-based positions
Diagnosis
Diagnosis combines a clinical examination that reproduces pain with specific extension and rotation movements, along with imaging such as X-ray or MRI showing facet joint degeneration. Diagnostic injections are sometimes used to confirm the facet joint as the specific pain generator.
Treatment Options
- Physiotherapy focused on flexion-based exercises and core stabilization
- Postural adjustments to reduce sustained extension loading
- Anti-inflammatory medication for symptomatic flare-ups
- Facet joint injections for more persistent, well-localized pain
- Radiofrequency ablation considered for cases with recurrent, confirmed facet-driven pain
Frequently Asked Questions
What is facet joint arthropathy?
It refers to degeneration or arthritis affecting the small joints at the back of the spine that guide and stabilize movement, commonly contributing to localized back or neck pain.
How is facet joint pain different from disc-related pain?
Facet joint pain typically worsens with extension and twisting movements and improves with flexion, while disc-related pain often worsens with prolonged sitting or forward bending.
Can facet joint arthropathy be managed without injections?
Yes, many cases respond well to physiotherapy and activity modification, with injections reserved for more persistent or significant cases.
