Cervical posterior disc compression collapse occurs when one or more intervertebral discs in the neck lose height or integrity toward the back (posterior) of the spine, causing pressure on spinal nerves or the spinal cord. This process often follows degeneration, injury, or sudden trauma, and can lead to neck pain, numbness, or weakness in the arms and hands.
Anatomy
Understanding the normal structure of the cervical intervertebral disc and surrounding tissues helps explain how collapse leads to symptoms.
Structure & Location
Intervertebral Disc: A sponge‐like cushion sitting between each pair of vertebral bodies (bones) from C2 to C7.
Components:
Annulus Fibrosus: Tough outer ring of concentric fibrocartilage layers.
Nucleus Pulposus: Gelatinous core rich in water and proteoglycans.
Location: Between each cervical vertebra in the front of the neck, just behind the throat and airway.
Origin & Insertion (Attachments)
Superior Endplate: The top of each disc firmly attaches to the lower surface of the vertebral body above.
Inferior Endplate: The bottom of each disc attaches to the upper surface of the vertebral body below.
These attachments anchor the disc, allowing it to bear load and maintain spacing.
Blood Supply
Outer Annulus: Receives small blood vessels from branches of the vertebral and cervical arteries.
Inner Annulus & Nucleus: Largely avascular; rely on diffusion through the endplates for nutrients.
Nerve Supply
Sinuvertebral (Recurrent Meningeal) Nerves: Innervate the outer annulus and adjacent ligaments.
Dorsal Root Ganglia: Transmit pain signals when the annulus is irritated.
Functions
Shock Absorption: Distributes mechanical forces during movement.
Load Distribution: Spreads weight evenly across vertebral bodies.
Mobility: Allows bending, twisting, and flexion of the neck.
Height Maintenance: Keeps proper spacing for nerves to exit the spinal canal.
Stability: Helps maintain vertebral alignment.
Protection: Shields the spinal cord and nerve roots from compressive forces.
Types of Posterior Disc Compression Collapse
Degenerative Collapse: Age‐related wear leads to loss of disc height.
Traumatic Collapse: Sudden injury (e.g., car accident) damages the disc.
Bulging Disc: Outer annulus bulges backward without a full tear.
Herniated (Prolapsed) Disc: Nucleus pushes through a tear in the annulus.
Extruded Disc: Nucleus material extends beyond the disc space.
Sequestrated Disc: A fragment of nucleus separates and migrates.
Post-Surgical Collapse: Disc height loss after procedures like discectomy.
Congenital Collapse: Rare developmental defects leading to weak discs.
Mechanical Collapse: Chronic overload or poor posture stresses the disc.
Infectious Collapse: Discitis from infection causes structural failure.
Causes
Aging: Natural degeneration of disc fibers.
Genetics: Family history of early disc degeneration.
Repetitive Strain: Work or sports activities stressing the neck.
Trauma: Sudden impact or whiplash injuries.
Poor Posture: Forward head carriage increases posterior load.
Smoking: Impairs disc nutrition and healing.
Obesity: Extra weight increases axial stress.
Heavy Lifting: Improper technique damages discs.
Vibration Exposure: Driving or machinery vibration accelerates wear.
Occupational Hazards: Jobs requiring head-down work (e.g., mechanics).
Inflammation: Chronic inflammatory conditions (e.g., rheumatoid arthritis).
Infection: Bacterial infection of the disc (discitis).
Tumors: Rare growths eroding disc substance.
Metabolic Disorders: Conditions like diabetes hamper disc health.
Nutritional Deficits: Lack of vitamins slows repair.
Radiation Therapy: Can weaken disc tissue.
Hormonal Changes: Post-menopausal changes reduce collagen.
Autoimmune Diseases: Attack disc components.
Sedentary Lifestyle: Weak muscles fail to support the spine.
Excessive Cervical Motion: Hyperflexion/hyperextension injuries.
Symptoms
Neck Pain: Often deep, aching, worse with movement.
Stiffness: Reduced range of motion in the neck.
Radicular Pain: Sharp shooting pain down the arm.
Numbness: Loss of sensation in the shoulder, arm, or hand.
Tingling: “Pins and needles” in the fingers.
Weakness: Gripping difficulty or arm weakness.
Headaches: Cervicogenic headaches at the base of the skull.
Shoulder Pain: Referral pain around the shoulder blade.
Balance Problems: If spinal cord is compressed.
Coordination Loss: Trouble with fine motor tasks.
Muscle Spasms: Involuntary contractions in neck muscles.
Fatigue: General tiredness from chronic pain.
Sleep Disturbance: Pain prevents restful sleep.
Neck Crepitus: Grinding sounds with movement.
Clumsiness: Dropping objects due to coordination loss.
Hyperreflexia: Exaggerated reflexes if cord involved.
Gait Changes: Shuffling steps from cord compression.
Bowel/Bladder Issues: Late sign of severe myelopathy.
Autonomic Dysfunction: Very rare with high cervical collapse.
Psychological Distress: Anxiety or depression from chronic pain.
Diagnostic Tests
Medical History & Physical Exam: Key first step.
Spurling’s Test: Neck extension and rotation to reproduce arm pain.
Lhermitte’s Sign: Electric shock sensation on neck flexion.

Frequently Asked Questions
What exactly is posterior disc compression collapse?
It’s when a neck disc’s back part loses height or integrity, pressing on nerves or the spinal cord.How is it different from a herniated disc?
A herniation means nucleus bulges through, whereas collapse refers to overall loss of disc height.Can it heal on its own?
Mild cases may improve with rest, PT, and posture changes; severe collapse often needs medical intervention.What imaging is best?
MRI is the gold standard for showing soft-tissue and nerve involvement.Are injections helpful?
Yes—epidural steroid or PRP injections can reduce inflammation and pain.When is surgery necessary?
If neurological deficits develop or conservative treatments fail after 6–12 weeks.Is disc replacement better than fusion?
Disc replacement preserves motion, but not all patients are candidates.How long is recovery after ACDF?
Most return to work in 4–6 weeks; full fusion may take 3–6 months.Will I need a neck brace?
Short-term use may help comfort, but prolonged immobilization can weaken muscles.Can exercise worsen collapse?
Improper technique can worsen it; always follow a guided PT program.Does weight loss really help?
Yes—less body weight means less stress on the cervical spine.Are there any home remedies?
Heat/cold therapy, gentle stretching, and ergonomic adjustments can help.What’s the long-term outlook?
With proper management, most maintain function and reduce pain long term.Can I still drive?
Mild cases usually allow safe driving; severe pain or weakness requires evaluation.Is this condition common?
Disc degeneration is very common with age; collapse severe enough to cause symptoms affects about 10–20% of adults over 50.
