Cervical Subarticular Disc Compression Collapse is a condition of the neck (cervical spine) in which one of the cushioning discs between two adjacent vertebrae weakens and loses height (collapse) in its subarticular zone—the part just under the facet joint. As the disc collapses, it can press on nearby nerve roots or the spinal cord itself. This pressure causes pain, numbness, weakness, or other nerve-related problems in the neck, shoulders, arms, or hands.
Anatomy
Structure & Location
Intervertebral Disc: A round, flat cushion made of an outer fibrous ring (annulus fibrosus) and an inner gel-like core (nucleus pulposus).
Subarticular Zone: The area immediately below the facet joint where spinal nerves exit.
Location in the Neck: Between the vertebral bodies of the cervical spine (C1 through C7), most often affecting levels C5–C6 or C6–C7.
Origin & Insertion
The disc “originates” where the annulus fibrosus attaches firmly to the top and bottom bony endplates of adjacent vertebral bodies.
It “inserts” along those same endplates, forming a tight seal that holds the nucleus pulposus in place.
Blood Supply
Discs are mostly avascular (no direct blood vessels) in their core.
Peripheral vessels from the vertebral bodies and small capillaries supply the outer layers of the annulus fibrosus.
Nerve Supply
Tiny branches of the sinuvertebral nerves wrap around the outer annulus.
These nerves carry pain signals when the disc is injured or collapses.
Key Functions
Shock Absorption: Cushions impact when you move or bear weight.
Load Distribution: Spreads pressure evenly across the vertebral bodies.
Flexibility: Allows the neck to bend, twist, and tilt.
Stability: Helps keep adjacent vertebrae in correct alignment.
Height Maintenance: Keeps proper spacing for nerve roots to exit.
Protection: Shields the spinal cord and nerve roots from direct impact.
Types
Cervical subarticular disc collapse can be classified by both shape and severity:
By Shape (Morphology):
Bulge: Generalized rounding of the disc margin.
Protrusion: Focal extension of the disc beyond its normal boundary, <25% of disc circumference.
Extrusion: Nucleus material pushes through a tear in the annulus, >25% of disc circumference.
Sequestration: Free fragments of disc material break off and move into the spinal canal.
By Severity (Height Loss):
Mild Collapse: Up to 25% loss of normal disc height.
Moderate Collapse: 25–50% loss.
Severe Collapse: More than 50% loss, leading to marked narrowing of the neural foramen.
Causes

Frequently Asked Questions
What exactly is Cervical Subarticular Disc Compression Collapse?
It’s when a neck disc under the facet joint loses height and presses on nerves or the spinal cord.How is it different from a regular herniated disc?
A herniation is disc material bulging or leaking out. Collapse is loss of disc height, often with nerve root narrowing.What are the first signs I should watch for?
Early signs include stiff neck, mild radiating arm pain, or tingling in your fingers.Can it heal on its own?
Mild cases may improve with rest, physical therapy, and time, but severe collapse often needs more treatment.What home exercises help?
Gentle neck stretches, chin tucks, and shoulder blade squeezes under a physical therapist’s guidance.Are steroid injections safe?
Yes, when done by an experienced provider; they reduce inflammation and pain for weeks to months.What are the risks of surgery?
Possible risks include infection, bleeding, nerve injury, or failure to relieve symptoms.How long is recovery after ACDF?
Most people return to light activities in 4–6 weeks; full fusion may take 3–6 months.Will I need a neck brace after surgery?
Sometimes a soft collar is used for a few days; hard collars are less common now.Can poor posture really cause this?
Yes—holding your head forward for long hours stresses discs and accelerates collapse.What pain medicines work best?
NSAIDs like naproxen or ibuprofen, plus muscle relaxants if you have spasms.Does weight loss help?
Losing extra pounds reduces overall spinal load and can ease symptoms.Is physical therapy always required?
It’s highly recommended to strengthen muscles and prevent recurrence.Will I ever get full motion back?
Many patients recover most motion, though some stiffness can remain, especially after fusion.How do I prevent future problems?
Keep good posture, do neck exercises daily, maintain a healthy weight, and avoid repetitive strain.
