Herniated Cervical Intervertebral Disc between C2 – C3

A herniated cervical intervertebral disc between the second (C2) and third (C3) cervical vertebrae occurs when the gelatinous core (nucleus pulposus) of the C2–C3 disc pushes through a tear in the outer ring (annulus fibrosus), pressing on adjacent nerves or the spinal cord. This can lead to neck pain, radiating arm discomfort, numbness, and muscle weakness in the areas served by the affected nerves .

Anatomy of the C2–C3 Intervertebral Disc

Structure & Location

The C2–C3 disc sits between the body of the axis (C2) and the body of C3, acting as a cushion and allowing motion in the upper neck. Like all intervertebral discs, it comprises three main parts: the outer annulus fibrosus, the inner nucleus pulposus, and the cartilaginous endplates that anchor the disc to the vertebrae above and below .

Origin & Insertion

Though discs do not “originate” or “insert” like muscles, the C2–C3 disc is firmly attached via its cartilaginous endplates to the superior endplate of C3 and the inferior endplate of C2, ensuring stability while permitting controlled flexion, extension, lateral bending, and rotation .

Blood Supply

Intervertebral discs are largely avascular in adults; nutrient and oxygen exchange occur by diffusion through the cartilaginous endplates from small capillaries in the vertebral bodies. In childhood, discs have a richer blood supply, but by adulthood, they rely primarily on endplate diffusion for nourishment .

Nerve Supply

Sensory fibers from the recurrent meningeal branches (sinuvertebral nerves) of the cervical spinal nerves penetrate the outer third of the annulus fibrosus, conveying pain signals when the disc is injured or inflamed MSD Manuals.

Key Functions

1. Shock Absorption – Distributes compressive forces during head and neck movements.

2. Load Bearing – Bears up to 20% of the cervical spine’s vertical load.

3. Motion Facilitation – Enables flexion, extension, lateral bending, and rotation.

4. Spinal Stability – Maintains vertebral alignment and intervertebral spacing.

5. Protection – Shields the spinal cord and nerve roots from compressive injury.

6. Height Maintenance – Preserves the vertical height between C2 and C3, contributing to overall neck length and posture .

Types of C2–C3 Disc Herniation

1. Protrusion – Bulging of the disc without annular rupture.

2. Extrusion – Nucleus material breaks through the annulus but remains attached.

3. Sequestration – A fragment of nucleus pulposus detaches and migrates.

4. Central herniation – Disc material impinges on the spinal cord centrally.

5. Paracentral herniation – Material compresses one side of the spinal canal.

6. Foraminal (lateral) herniation – Compression within the intervertebral foramen.

7. Far lateral herniation – Disc material migrates beyond the foramen, affecting exiting nerve roots Verywell Health.

Causes

Herniation at C2–C3 can result from a combination of age, wear and tear, injury, and lifestyle factors. Common causes include:

1. Age-related degeneration – Discs lose hydration and elasticity over time .

2. Repetitive strain – Chronic neck flexion or rotation (e.g., desk work).

3. Acute trauma – Falls, car accidents, or sports injuries.

4. Heavy lifting – Improper lifting techniques place excessive axial load.

5. Poor posture – Forward head posture increases disc stress.

6. Smoking – Impairs disc nutrition and accelerates degeneration.

7. Obesity – Extra weight increases spinal loading.

8. Genetic predisposition – Family history of disc disease.

9. Occupational hazards – Vibration (e.g., heavy machinery operators).

10. High-impact sports – Repeated jarring forces on the neck.

11. Connective tissue disorders – Conditions like Ehlers–Danlos syndrome weaken annular fibers.

12. Dehydration – Reduced disc hydration lessens shock absorption.

13. Nutritional deficiencies – Poor diet impairs tissue repair.

14. Sedentary lifestyle – Weak neck and core muscles fail to support spine.

15. Sudden hyperflexion/hyperextension – Whiplash injuries tear annulus.

16. Disc tears – Small annular fissures can propagate under stress.

17. Spinal instability – Ligament laxity increases disc micromotion.

18. Previous spine surgery – Alters biomechanics and loading patterns.

19. Tumors – Rarely, space-occupying lesions can weaken disc integrity.

20. Infections – Discitis can damage disc structure .
