Degenerative Bones, Joints, and Spine Care (A - Z)

A cervical disc extrusion happens when the soft inner part of a disc in your neck pushes out through a tear in its tougher outer layer. When this “herniation” is directly in the middle it’s called a central extrusion. If it bulges slightly to the left or right of center, it’s a paracentral extrusion. Both can press on nearby nerves or the spinal cord, causing pain and other problems.

Anatomy of a Cervical Disc

Structure & Location

  • Intervertebral Disc: A round, cushion-like pad between two neck bones (vertebrae), from C2–C3 down to C7–T1.

  • Annulus Fibrosus: Tough outer ring of collagen fibers.

  • Nucleus Pulposus: Soft, jelly-like center that absorbs shock.

Attachments

  • Discs are wedged between vertebrae; they have no muscles attaching directly but are held by ligaments (anterior and posterior longitudinal ligaments).

Blood Supply

  • Tiny blood vessels in the outer annulus; inner parts get nutrients by diffusion from vertebral endplates.

Nerve Supply

  • Small nerves called sinuvertebral nerves enter the outer annulus; inner disc layers have no direct nerve endings (which is why inner tears often feel less painful).

Six Functions

  1. Shock Absorption: Cushions everyday movements like walking or jumping.

  2. Load Distribution: Spreads weight evenly across vertebrae.

  3. Flexibility: Allows neck bending, twisting, and side-to-side motion.

  4. Height Maintenance: Keeps space between vertebrae for nerve roots.

  5. Spinal Stability: Works with muscles and ligaments to hold the neck upright.

  6. Protection: Shields spinal cord and nerve roots from sudden jolts.

Types of Cervical Disc Herniation

  1. Protrusion: Annulus bulges without a full tear.

  2. Extrusion: Nucleus squeezes out through a tear—may be central or paracentral.

  3. Sequestration: A fragment of disc breaks off and floats in the spinal canal.

  4. Contained: The disc material is still within the annulus.

  5. Non-contained: Disc material escapes annulus entirely.

  6. Massive Herniation: Large disc material compressing spinal cord widely.

Causes

  1. Age-Related Degeneration: Discs lose water and become brittle.

  2. Wear and Tear: Daily movement over decades weakens fibers.

  3. Sudden Trauma: Car accidents or falls.

  4. Repetitive Strain: Heavy lifting or awkward postures at work.

  5. Genetics: Family history of disc problems.

  6. Smoking: Reduces disc nutrition.

  7. Obesity: Extra weight increases spinal load.

  8. Poor Posture: Forward head position stresses discs.

  9. Sedentary Lifestyle: Weak neck muscles offer less support.

  10. High-Impact Sports: Football, gymnastics.

  11. Vibration Exposure: Long-term vehicle driving.

  12. Heavy Backpack Use: Especially in children/teens.

  13. Pathologic Fractures: Osteoporosis.

  14. Inflammatory Diseases: Rheumatoid arthritis.

  15. Infection: Rare discitis.

  16. Spinal Tumors: Cause structural weakness.

  17. Metabolic Disorders: Diabetes affects tissue health.

  18. Vitamin Deficiency: Low vitamin D affects bone and disc health.

  19. Endocrine Issues: Thyroid dysfunction alters tissue metabolism.

  20. Prior Spinal Surgery: Alters biomechanics and stresses adjacent discs.

Symptoms

  1. Neck Pain: Often worse with movement.

  2. Stiffness: Difficulty turning the head.

  3. Shoulder Pain: Referred from C4–C5 discs.

  4. Arm Pain (Radiculopathy): Sharp, shooting pain down one arm.

  5. Numbness: “Pins and needles” in arm or hand.

  6. Tingling: Especially in fingers.

  7. Weakness: In arm muscles, making gripping hard.

  8. Headache: Base of skull.

  9. Scapular Pain: Between shoulder blades.

  10. Muscle Spasms: In neck or shoulder.

  11. Reduced Range of Motion: Cannot tilt head fully.

  12. Balance Problems: If spinal cord is pressed centrally.

  13. Clumsiness: Dropping things.

  14. Reflex Changes: Exaggerated or diminished arm reflexes.

  15. Sensory Loss: Partial loss of touch sensation.

  16. Lhermitte’s Sign: Electric shock sensation down the spine on neck flexion.

  17. Gait Disturbance: If myelopathy exists.

  18. Bladder or Bowel Issues: Rare, indicates serious spinal cord compression.

  11. MRI: Best for visualizing disc and nerve compression.

  12. CT Scan: Good for bone detail and calcified discs.

  13. Myelogram: Dye injected into spinal canal before CT to show cord compression.

  14. Discography: Dye injected into disc to reproduce pain.

  15. Electromyography (EMG): Tests nerve conduction to muscles.

  16. Nerve Conduction Velocity: Measures speed of nerve signals.

  17. Ultrasound: Rare for soft-tissue assessment.
