What Is a Facet Joint?
A facet joint is a small synovial joint at the back of the spine that connects neighboring vertebrae. Facet joints guide spinal movement and help limit excessive twisting or sliding. Each joint contains cartilage, a capsule, and sensitive nerve endings. Irritation or wear in a facet joint may contribute to localized back or neck pain.

Key Takeaways About Facet Joint
- Facet joints sit behind the vertebral bodies.
- Their surfaces guide bending and rotation.
- Facet joint pain differs from disc-related pain.
How Facet Joint Works
A facet joint connects the back portions of neighboring vertebrae. Its smooth cartilage-covered surfaces meet inside a capsule that helps the joint move with the spine. Small nerves around the capsule can detect pressure and position. Movement occurs as the vertebrae bend, extend, or rotate.

Facet joints help direct spinal motion while limiting excessive sliding between vertebrae. Their position changes by spinal region, so cervical, thoracic, and lumbar facet joints support different movement patterns. A clinician considers the pain location, movement response, tenderness, and related findings when assessing whether a facet joint may contribute to back pain. Referred pain can also make the source feel less direct than the joint itself.
From the Advanced Injury Care Clinic team
When we assess a facet joint during back pain care, we consider the pain pattern, spinal movement, and nearby muscle or nerve findings. Our team also checks whether joint loading or specific movements reproduce the person’s symptoms. These observations help us plan care around the whole movement pattern instead of one structure alone.
Facet Joint in Practice: A Real-World Example
A person with lower back pain may feel more discomfort during extension or rotation than during neutral standing. During Back Pain Treatment, the clinical assessment considers facet joint involvement alongside the lumbar spine, muscles, discs, and nerve-related findings.
