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. Each joint has cartilage, a joint capsule, and sensory nerves. Irritation or wear in these structures can 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 is not the same as disc pain.
How Facet Joint Works
A facet joint connects the back portions of neighboring vertebrae and helps direct spinal motion. Smooth cartilage covers the joint surfaces, while a capsule surrounds the joint and helps hold it together. Small sensory nerves near the capsule can detect movement and irritation.

Facet joints work with the intervertebral disc and spinal muscles during bending, extension, and rotation. The joint's angle differs across the neck, mid-back, and lower back, so each region permits a different pattern of movement. Wear, inflammation, or altered movement can increase stress around a facet joint and produce pain near the spine. Facet-related symptoms may stay local or spread a short distance into nearby tissues.
From the Advanced Injury Care Clinic team
When we assess facet joint concerns during Back Pain Treatment, we consider the pain location, spinal movement, muscle tension, and related findings together. Our team also reviews how symptoms change with bending, extension, or rotation. This helps us distinguish a facet-related pattern from other possible sources of back pain.
Facet Joint in Practice: A Real-World Example
A person with lower back pain may notice more discomfort during backward bending or rotation. During Back Pain Treatment, the clinician may examine spinal movement and nearby muscle tension while considering whether the pattern fits facet joint irritation.
