Herniated Cervical Disc Between C3- C4

A herniated cervical disc between the third (C3) and fourth (C4) vertebrae occurs when the soft inner core (nucleus pulposus) of the intervertebral disc pushes through a tear in its tough outer layer (annulus fibrosus). This protrusion can press on nearby spinal nerves or the spinal cord itself, causing pain, numbness, or weakness in the neck, shoulders, arms, or hands Merck ManualsWebMD.

Anatomy of the C3–C4 Intervertebral Disc

1. Structure
   The C3–C4 disc is made of two main parts:

   • Annulus fibrosus: A ring of strong, layered cartilage that surrounds the nucleus.

   • Nucleus pulposus: A gel-like center that absorbs shock and allows flexibility Spine Info.

2. Location
   This disc sits between the third (C3) and fourth (C4) cervical vertebral bodies in the neck, forming part of the spinal column that supports the head and allows nodding and rotation PhysiopediaKenhub.

3. Origin & Insertion
   Rather than muscles, intervertebral discs attach via cartilaginous endplates to the bony vertebrae above (C3) and below (C4). These endplates anchor the disc in place and allow nutrients to diffuse from the vertebral bodies into the disc orthopaedicmedicineonline.com.

4. Blood Supply
   Discs have no direct blood vessels; they rely on diffusion from tiny vessels in the adjacent vertebral endplates, making healing slow if injured orthopaedicmedicineonline.com.

5. Nerve Supply
   Sensory nerve fibers from the sinuvertebral nerve penetrate the outer annulus fibrosus, explaining why tears here can cause sharp, localized pain AAFP.

6. Functions

   1. Shock absorption: Cushions forces from head movement and weight.

   2. Flexibility: Allows bending, twisting, and extension of the neck.

   3. Load distribution: Evenly spreads pressure across vertebrae.

   4. Spacer: Maintains proper spacing for nerve roots to exit the spine.

   5. Alignment: Helps preserve the natural curve of the cervical spine.

   6. Protective barrier: Keeps vertebrae from grinding against each other PhysiopediaSpine Info.

Types of Cervical Disc Herniation

Doctors classify herniations by how far the nucleus pulposus pushes out:

• Bulging disc: The annulus fibrosus balloons outward but stays intact.

• Protrusion: The nucleus pushes into the annulus, creating a focal “bulge.”

• Extrusion: The nucleus breaks through the annulus but remains connected to the disc.

• Sequestration: A fragment of nucleus pulposus breaks free and may move into the spinal canal Illness Hacker.

Causes of C3–C4 Disc Herniation

Each of the following can contribute to tearing or degeneration of the C3–C4 disc:

1. Age-related wear
   Natural drying and stiffening of discs over time weaken the annulus.

2. Repetitive neck motions
   Frequent twisting or bending strains the annular fibers.

3. Heavy lifting
   Sudden loads increase internal disc pressure, risking tears.

4. Trauma
   Falls or car accidents can crack the annulus.

5. Poor posture
   Slouching or forward head posture adds constant stress.

6. Smoking
   Reduces blood flow to discs, impairing nutrient diffusion.

7. Obesity
   Extra weight increases mechanical load on cervical discs.

8. Genetic predisposition
   Some people inherit weaker disc structure.

9. Occupational strain
   Jobs involving overhead work or vibrating machinery.

10. Sedentary lifestyle
    Weak neck muscles fail to support the spine.

11. High-impact sports
    Football, gymnastics, or wrestling can jar the spine.

12. Dehydration
    Low fluid content makes discs less pliable.

13. Inflammatory conditions
    Arthritis or autoimmune diseases can damage discs.

14. Poor sleep posture
    Using unsupportive pillows twists the neck overnight.

15. Whiplash injuries
    Rapid back-and-forth neck motion strains discs.

16. Disc degeneration disease
    A progressive condition that thins and weakens discs.

17. Occupational vibration
    Long-term exposure (e.g., jackhammers) accelerates wear.

18. Radiation exposure
    Rarely, radiation therapy can damage disc cells.

19. Previous neck surgery
    Alters biomechanics and places extra stress on adjacent discs.

20. Nutritional deficiencies
    Lack of vitamins C and D may impair disc matrix health SpringerLink.
