C3–C4 facet joint arthritis is a form of wear-and-tear inflammation affecting the small paired joints (facet joints) that link the third and fourth cervical vertebrae in the neck. Over time, the smooth cartilage that cushions these joints can thin or crack, causing bone edges (osteophytes) to rub or press on nearby tissues. This leads to pain, stiffness, and reduced neck mobility. Because the C3–C4 level sits close to the top of the spine, arthritis here can also trigger headaches, nerve irritation, and muscle spasms in the upper shoulders and head.
Anatomy of the C3–C4 Facet Joints
Structure
Each facet joint is a true synovial joint formed by the inferior articular process of C3 meeting the superior articular process of C4. A thin layer of smooth cartilage covers each bone surface, while a fibrous capsule lined with synovial membrane surrounds the joint and produces lubricating fluid.
Location
The C3–C4 facet joints sit at the back of the neck, just off the midline. They lie posterior to the intervertebral disc that separates C3 from C4, helping to stabilize and guide motion between these two vertebrae.
Origin & Insertion (Articular Surfaces)
Origin: The inferior articular processes of C3.
Insertion: The superior articular processes of C4.
These matching surfaces lock together much like two shallow cups, allowing smooth gliding during neck movements.
Blood Supply
Small branches from the ascending cervical artery—a branch of the thyrocervical trunk—supply the joint capsule and surrounding ligaments. Tiny capillaries from the vertebral artery also contribute to the joint’s nourishment.
Nerve Supply
Sensory fibers from the medial branches of the dorsal rami of the C3 spinal nerve carry pain and position signals from the C3–C4 facet joints into the spinal cord.
Key Functions
Load Bearing: They share vertical pressure with intervertebral discs when the head and neck bear weight.
Guiding Movement: Facet orientation controls and limits motion, preventing over-rotation or excessive flexion/extension.
Shock Absorption: The joint fluid and cartilage cushion jolts during sudden head movements.
Spinal Stability: By “locking” adjacent vertebrae, facets help maintain alignment, especially during twisting or bending.
Protecting Neural Elements: They limit extreme ranges of motion, guarding against pinching of spinal nerves and cord.
Proprioception: Nerve endings in the joint capsule provide feedback on neck position, aiding coordination and balance.
Types of Facet Joint Arthritis at C3–C4
Osteoarthritis (Degenerative): The most common form, caused by gradual cartilage wear and tear.
Inflammatory Arthritis: Includes rheumatoid arthritis and other autoimmune disorders attacking the joint lining.
Post-Traumatic Arthritis: Develops after neck injuries such as whiplash or fractures that damage cartilage.
Septic (Infectious) Arthritis: A rare form where bacteria invade the joint space, causing acute inflammation.
Causes of C3–C4 Facet Joint Arthritis
Age-Related Wear: Over decades, cartilage thins and roughens, leading to joint degeneration.
Repeated Neck Strain: Poor posture at work or during sports can overload facet joints.
Whiplash Injuries: Sudden flexion-extension motions can crack cartilage or damage the joint capsule.
Previous Neck Surgery: Altered mechanics after surgery can accelerate facet wear.
Genetic Predisposition: Family history of osteoarthritis raises risk of early-onset degeneration.
Obesity: Excess body weight increases mechanical stress on all spinal joints.
Smoking: Toxins impair blood flow and cartilage repair, speeding degeneration.
Inflammatory Diseases: Autoimmune conditions like rheumatoid arthritis attack joint linings.
Infection: Bloodborne bacteria can infect the synovial membrane, triggering septic arthritis.
Occupational Hazards: Jobs involving heavy lifting or prolonged neck extension (e.g., painting overhead).
Congenital Spine Abnormalities: Misaligned facets or fused vertebrae increase local stress.
Poor Ergonomics: Non-adjustable chairs and low screens force unhealthy neck positions.
High-Impact Sports: Football, gymnastics, and diving risk neck hits and joint injury.
Repetitive Motions: Activities like heavy manual work or extended phone use.
Cartilage Disorders: Conditions like chondromalacia reduce cartilage resilience.
Diabetes: High blood sugar can weaken joint tissues over time.
Hormonal Changes: Post-menopausal estrogen loss can affect joint health.
Vitamin D Deficiency: Poor bone health increases load on facet joints.
Calcium Metabolism Disorders: Abnormal mineral balance may weaken bone margins.
Neuromuscular Imbalance: Weak neck muscles shift stability burden to the joints.

Stiffness: Difficulty turning or tilting the head, especially after rest.
Referred Shoulder Pain: Pain spreading into the upper shoulders or between the shoulder blades.

Frequently Asked Questions
What exactly is C3–C4 facet joint arthritis?
C3–C4 facet joint arthritis is degeneration of the tiny joints linking the third and fourth cervical vertebrae. As cartilage breaks down, bones rub together, causing inflammation, pain, and stiffness in the neck.What causes this arthritis in the neck?
It most often results from age-related wear and tear but can also follow injuries like whiplash, inflammatory diseases (e.g., rheumatoid arthritis), or infections.How is C3–C4 facet arthritis diagnosed?
Your doctor will review your history, perform a physical exam, and order imaging—typically X-rays, CT, or MRI. Diagnostic injections may confirm the facet joint as the pain source.Can this arthritis lead to nerve problems?
Yes. Bone spurs or swelling can press on nearby nerve roots, causing arm pain, numbness, or weakness (cervical radiculopathy).What lifestyle changes help manage symptoms?
Good posture, regular neck exercises, ergonomic workspace adjustments, and weight management all reduce joint stress and pain.Are there effective non-drug treatments?
Physical therapy, heat/cold packs, acupuncture, TENS units, and massage often relieve pain and improve mobility without medication.When are medications needed?
If home measures fail, doctors may prescribe NSAIDs, muscle relaxants, or, in severe cases, short-term opioids or injectable steroids.Is surgery ever required?
Surgery is reserved for severe pain not controlled by other means or when there’s significant nerve compression causing weakness or incoordination.How long does recovery take after facet injections?
Many people notice relief within 48–72 hours; benefits can last weeks to months.Can the arthritis at C3–C4 worsen over time?
Degenerative arthritis is progressive, but symptoms can often be well-managed with treatment and lifestyle adjustments.Does exercise make facet arthritis worse?
Gentle, guided exercises strengthen supporting muscles and usually improve symptoms, though high-impact or extreme ranges should be avoided.Are there alternative medicines that help?
Supplements like glucosamine may offer mild relief for some, but evidence is mixed. Always discuss supplements with your healthcare provider.Can poor sleep position aggravate arthritis?
Yes—using a pillow that doesn’t support your neck’s natural curve can increase morning stiffness and pain.What is the long-term outlook?
With proper management, most people maintain good function and minimal pain, though occasional flare-ups can occur.How can I prevent it from happening in younger years?
Early attention to posture, regular neck strengthening, ergonomic setups, and avoiding smoking are key preventive steps.
