C3-C4 facet joint syndrome is a condition affecting the small joints in the neck, leading to pain and reduced mobility. The cervical spine consists of seven vertebrae labeled C1 through C7. The C3-C4 facet joints are located between the third (C3) and fourth (C4) cervical vertebrae. These joints, also known as zygapophyseal joints, are synovial joints that allow for smooth movement between the vertebrae.
Anatomy of the C3–C4 Facet Joint
Structure and Location
The C3–C4 facet joint is a paired synovial joint formed by the inferior articular process of the third cervical vertebra (C3) articulating with the superior articular process of the fourth cervical vertebra (C4). Each joint is lined with a smooth layer of articular cartilage and surrounded by a fibrous capsule reinforced by ligaments. It lies immediately posterior to the spinal canal and just lateral to the vertebral arch PhysioPedia.
Origin and Insertion of the Joint Capsule
The joint capsule attaches tightly around the margins of the articular facets: its superior band originates on the rim of C3’s inferior facet and its inferior band inserts onto the rim of C4’s superior facet. This cuff of tissue seals the joint and contains synovial fluid, which nourishes and lubricates the articular surfaces Ontosight.ai.
Blood Supply
Blood to the C3–C4 facet joint comes predominantly from small branches of the vertebral and deep cervical arteries. These vessels penetrate the joint capsule, supplying oxygen and nutrients to the cartilage and synovium Medscape.
Nerve Supply
Sensory innervation is provided by the medial branches of the dorsal rami of the C3 and C4 spinal nerves. Each C3–C4 joint typically receives articular branches from the medial branch at its own level (C4) and from the one above (C3), allowing precise location of joint pain PhysioPediaResearchGate.
Key Functions
Load Bearing: Shares vertical load with intervertebral discs, reducing stress on the discs.
Motion Guidance: Directs and limits flexion, extension, lateral bending, and rotation of the neck.
Stability: The paired joints resist excessive shear and translational forces.
Proprioception: Richly innervated with mechanoreceptors that inform the brain about joint position and movement.
Protection of Neural Structures: Helps prevent undue narrowing of the spinal canal during motion.
Shock Absorption: Synovial fluid and cartilage cushion loads transmitted through the cervical spine.
Types of C3–C4 Facet Joint Syndrome
Acute Traumatic Syndrome – sudden injury from falls or impact

Frequently Asked Questions (FAQs)
What causes C3–C4 facet joint syndrome?
Wear and tear (osteoarthritis), injury (whiplash), or inflammatory arthritis can damage the joint surfaces and capsule, leading to pain.How is it different from a herniated disc?
Facet pain arises from the small posterior joints of the spine, while a herniated disc involves the soft pad between vertebral bodies.Can imaging always diagnose it?
X-rays and MRI may show degeneration but cannot confirm the source; diagnostic injections are more specific.Is facet joint syndrome permanent?
It can be chronic, but many patients improve significantly with combined non-surgical treatments.Do I need surgery?
Surgery is a last resort, reserved for severe cases unresponsive to conservative care or with neurological compromise.Are steroid injections safe?
Yes, when performed under imaging guidance, they carry low risk and can provide months of relief.How long does radiofrequency ablation last?
Pain relief often lasts 6–12 months until the nerve regenerates.Can exercise worsen my pain?
Improper or excessive movements may aggravate pain; guided, gentle exercises are recommended.What is the recovery time after facet fusion?
Typically 3–6 months for fusion to solidify, with gradual return to activities.Will I have limited neck motion forever?
Most treatments aim to preserve or restore motion; only fusion permanently limits movement.Can stress cause facet joint pain?
Indirectly—stress can increase muscle tension around the joint, worsening pain.Is massage therapy effective?
Yes, it can reduce muscle spasm and improve circulation around the joint.Should I use a neck collar?
Short-term use (days) may help acute flare-ups but long-term immobilization weakens neck muscles.How do I prevent recurrence?
Maintaining posture, doing regular neck exercises, and ergonomic adjustments help prevent future episodes.When should I see a specialist?
If you have neurological symptoms, severe unrelenting pain, or no improvement after 6 weeks of conservative care.
