C6–C7 Facet Joint Arthritis

C6–C7 facet joint arthritis is a degenerative condition in which the small, paired synovial (facet) joints between the sixth (C6) and seventh (C7) cervical vertebrae wear down, become inflamed, and often enlarge, leading to neck pain, stiffness, and sometimes nerve root irritation Wikipedia. Below is an evidence-based, SEO-optimized overview presented in very simple plain English.

Anatomy of the C6–C7 Facet Joint

Structure and Location

The C6–C7 facet joint is one of two paired synovial plane joints at the back of the lower neck. It sits where the inferior articular process of C6 meets the superior articular process of C7, forming a small capsule-lined joint on each side of the vertebral canal Wikipedia; Radiopaedia.

Origin and Insertion

• Origin: The joint begins at the inferior articular process of the C6 vertebra.

• Insertion: It ends at the superior articular process of the C7 vertebra.
  These bony processes interlock like two facing plates, enabling controlled sliding and gliding movements.

Blood Supply

Arterial blood reaches the C6–C7 facet from the posterior spinal branches of the segmental spinal arteries (branches of the vertebral, ascending cervical, and costocervical trunk arteries). Small veins drain into the internal vertebral venous plexus, then into larger vertebral and segmental veins Home.

Nerve Supply

Each C6–C7 facet receives sensory fibers primarily from the medial branches of the dorsal (posterior) rami of the C6 and C7 spinal nerves. In some people, tiny direct facet branches also supply the joint capsule Wheeless’ Textbook of Orthopaedics; PMC.

Functions

1. Guide Motion: Directs and limits movements—flexion, extension, rotation, and side-bending in the neck.

2. Load Sharing: Bears up to 20% of the load when the neck extends, protecting intervertebral discs.

3. Stability: Prevents excessive forward sliding (anterior shear) of one vertebra over another.

4. Protect Neural Elements: Helps keep the opening (foramen) for nerves from narrowing too much.

5. Shock Absorption: Works with discs to cushion forces from head movement.

6. Proprioception: Houses sensors that tell the brain neck position and movement.

Types of C6–C7 Facet Joint Arthritis

Facet arthritis at C6–C7 can be classified both by cause and by radiographic severity:

• By Cause:

  • Primary (Degenerative) Osteoarthritis – Wear-and-tear with age.

  • Secondary Osteoarthritis – Follows neck injury or surgery.

  • Inflammatory Arthritis – Part of rheumatoid or ankylosing spondylitis.

  • Congenital Facet Tropism – Abnormal joint orientation from birth.

• **By Radiographic Grade (Kellgren-Lawrence for Cervical Facet):

  • Grade 0: Normal joint.

  • Grade 1: Doubtful/minimal osteophytes.

  • Grade 2: Definite osteophytes and possible joint-space narrowing.

  • Grade 3: Moderate narrowing, sclerosis, and larger osteophytes.

  • Grade 4: Severe joint-space loss, sclerosis, and large osteophytes PMC.
