C2–C3 Facet Joint Arthropathy

C2–C3 facet joint arthropathy is a degenerative condition affecting the small synovial joints that connect the second (axis) and third cervical vertebrae. In this condition, the cartilage lining the joint wears down, the joint space narrows, and bony spurs (osteophytes) form, leading to pain, stiffness, and reduced neck motion. It may also cause referred pain into the head, shoulders, or upper back. RadiopaediaMedscape

Anatomy

Structure and Location

Each facet (zygapophyseal) joint is a paired, true synovial joint lined by cartilage and enclosed in a fibrous capsule. At the C2–C3 level, the inferior articular facet of C2 fits against the superior articular facet of C3 on the back (posterior) and side (lateral) aspects of the vertebral arch. RadiopaediaMedscape

Origin and Insertion

Rather than muscles, facet joints are formed by the articular processes of adjacent vertebrae. The C2–C3 joint “originates” where the inferior articular process of C2 meets the superior articular process of C3; both surfaces are covered with smooth hyaline cartilage to allow gliding motion. Radiopaedia

Blood Supply

Arterial blood to the C2–C3 facet joint comes primarily from the posterior spinal branches of the vertebral and ascending cervical arteries. Venous blood drains via basivertebral and intervertebral veins into the internal and external vertebral venous plexuses. Home

Nerve Supply

Sensation to the C2–C3 facet joint is carried by the medial branches of the dorsal rami of spinal nerves, notably the third occipital nerve (a branch of C3) and occasionally accessory direct facet branches. The innervation pattern can form a plexus-like network around this level. PMC

Functions

  1. Guide and Limit Motion: Facet joints direct cervical flexion, extension, lateral flexion, and rotation.

  2. Stabilize: They provide posterior restraint to excessive movement.

  3. Load Transmission: They share axial loads with intervertebral discs.

  4. Protect Discs: By distributing stress, they shield discs from overload.

  5. Proprioception: Their mechanoreceptors inform the brain about head and neck position.

  6. Maintain Alignment: They help keep adjacent vertebrae properly aligned. Home

Types

By etiology, C2–C3 facet joint arthropathy can be:

  • Primary degenerative: Age-related wear and tear (osteoarthritis) of the joint.

  • Secondary: Resulting from inflammatory arthritis (e.g., rheumatoid arthritis), crystal deposition (gout, pseudogout), infection, or post-traumatic changes.

By severity, imaging-based Weishaupt grading classifies facet osteoarthritis into:

  • Grade 1 (Mild): Joint space narrowing <2 mm, small osteophytes, mild hypertrophy.

  • Grade 2 (Moderate): Moderate narrowing, osteophytes, subchondral sclerosis.

  • Grade 3 (Severe): Marked narrowing, large osteophytes, cysts, severe sclerosis. PMC

When to See a Doctor

If neck pain persists for more than a few weeks, is severe, or is accompanied by arm numbness, tingling, or weakness, obtain medical evaluation. Sudden severe pain after injury, fever, or bladder/bowel dysfunction also warrants urgent attention. Early diagnosis and treatment can prevent chronic pain and complications. Medscape

Frequently Asked Questions

  1. What is C2–C3 facet joint arthropathy?
    It’s degeneration of the synovial joint between the C2 and C3 vertebrae, marked by cartilage loss, bone spur formation, and narrowed joint space, causing neck pain and stiffness. Radiopaedia

  2. How is it diagnosed?
    Through history, physical exam, imaging (X-ray, CT, MRI), and confirmation with diagnostic facet joint or medial branch nerve blocks. Medscape

  3. What are the hallmark symptoms?
    Posterior neck pain, stiffness, reduced rotation/extension, occipital headaches, and occasional referred shoulder/scalp pain. Medscape

  4. Can it cause headaches?
    Yes—degeneration at C2–C3 often leads to occipital headaches due to shared nerve pathways. Medscape

  5. Is non-surgical treatment effective?
    Often—physical therapy, manual techniques, injections, and medications can control pain and improve function. Medscape

  6. When is surgery needed?
    For severe osteophytes compressing nerves/spinal cord, instability requiring fusion, or when conservative care fails. Radiology Key

  7. Which medications help most?
    NSAIDs, muscle relaxants, neuropathic agents (gabapentin), and in some cases, short-term opioids or steroids. Medscape

  8. What exercises are recommended?
    Gentle ROM stretches, isometric strengthening, and stabilization exercises under professional guidance. Medscape

  9. Are facet injections safe and effective?
    Yes—fluoroscopy-guided steroid or anesthetic injections can both diagnose and treat joint pain. Radiopaedia

  10. Will it worsen over time?
    It may progress, but appropriate treatment and lifestyle changes can slow degeneration and manage symptoms. Radiopaedia

  11. Can I prevent facet arthropathy?
    Maintaining good posture, neck exercises, ergonomic habits, and a healthy lifestyle all help reduce risk. Medscape

  12. How can I protect my neck at work?
    Use a supportive chair, adjust monitor height to eye level, take breaks to stretch, and avoid sustained extension. Medscape

  13. Should I rest or stay active?
    Avoid prolonged rest; gentle activity and guided exercises usually yield better outcomes than bed rest. Medscape

  14. Can pain recur after treatment?
    Yes—arthropathy is chronic. Periodic flare-ups may require repeat interventions like injections or adjustment of therapy. Pain Care Florida –

  15. When should I see a specialist?
    If pain persists despite conservative care for 6–8 weeks, or if you develop neurological signs, consult a spine specialist or pain physician. Medscape
