Cervical Internal Central Disc Disruption

Cervical Internal Central Disc Disruption (CICDD) happens when the soft inner core (nucleus pulposus) of a neck disc develops tiny tears or cracks in its annular ring without bulging outward as a true herniation. This internal breakdown can cause neck pain, stiffness, and reduced mobility by destabilizing the cushioning between vertebrae

Anatomy of the Cervical Intervertebral Disc

Structure and Location

The cervical intervertebral discs are fibrocartilaginous cushions that lie between adjacent vertebral bodies from C2–C3 down to C7–T1, forming six discs in the neck region of the human spine . Each disc has two main components:

• Annulus fibrosus: An outer ring made of 15–25 concentric layers (lamellae) of type I collagen arranged in a cross-ply “radial-ply” pattern, providing tensile strength and resistance to torsion and flexion .

• Nucleus pulposus: A central gelatinous core rich in proteoglycans (notably aggrecan) and water (about 88% by weight), responsible for distributing hydraulic pressure evenly under compressive loads .

In the cervical region, discs are thicker at the front (anteriorly) than at the back, contributing to the cervical lordosis that helps maintain head balance and shock absorption .

Origin and Insertion

Each cervical disc attaches directly to the hyaline cartilage endplates of the superior and inferior vertebral bodies. The annulus fibrosus inserts into the subchondral bone of these endplates, anchoring the disc securely between vertebrae and forming a fibrocartilaginous symphysis joint that allows slight movement while maintaining stability .

Blood Supply

In healthy adults, intervertebral discs are essentially avascular, receiving no direct blood vessels in their central regions. During embryonic development and in early life, small vessels extend into the outer annulus and endplates, but these deteriorate postnatally. Nutrient and gas exchange occur by diffusion through the vertebral endplates, driven by cyclic loading and unloading of the disc .

Nerve Supply

Sensory innervation of the cervical discs is limited to the outer one-third of the annulus fibrosus. The recurrent meningeal (sinuvertebral) nerves branch from the dorsal root ganglia, penetrate the posterior longitudinal ligament, and supply nociceptive fibers to the superficial lamellae of the annulus. No nerve fibers extend into the nucleus pulposus .

Functions

Cervical intervertebral discs perform six essential roles in spinal biomechanics:

1. Separation of vertebrae: Maintaining intervertebral height to protect nerve roots exiting via foramina.

2. Shock absorption: Distributing compressive loads evenly, reducing stress peaks on vertebral bodies.

3. Flexibility: Allowing controlled movements—flexion, extension, lateral bending, and axial rotation—between vertebral segments.

4. Stability: Acting as a ligamentous joint to hold vertebrae together, resisting shear and torsional forces.

5. Load transmission: Transmitting axial forces from the head and upper body through the cervical spine.

6. Protection of neural elements: Maintaining spacing to prevent impingement of the spinal cord and nerve roots .

Types of Cervical Internal Disc Disruption

Internal disc disruption (IDD) refers to fissuring or tearing of the annulus fibrosus and distortion of the nucleus pulposus without an external herniation. In the cervical spine, IDD can be classified by the extent of annular fissure penetration (Modified Dallas Classification) :

1. Grade I: Fissure extends into the inner one-third of the annulus fibrosus.

2. Grade II: Fissure reaches the middle one-third of the annulus.

3. Grade III: Fissure reaches the outer one-third of the annulus.

4. Grade IV: A circumferential tear that spreads around the annulus.

Grades III and IV are most often symptomatic due to ingrowth of nociceptive fibers into deeper annular layers.

Causes of Cervical Internal Disc Disruption

A combination of mechanical, biological, and lifestyle factors can lead to annular fissuring and nucleus distortion in the cervical discs. Major causes include:

1. Genetic predisposition affecting proteoglycan and collagen composition of the disc matrix .

2. Metabolic disorders (e.g., diabetes) impairing nutrient transport and matrix turnover .

3. Dysregulated cell signaling, accelerating matrix degradation and inflammation .

4. Oxidative stress, promoting breakdown of annular collagen fibers .

5. Mechanical overload from heavy lifting or axial compression beyond physiological limits .

6. Repetitive shear and compressive forces, such as those in manual labor and sports, leading to micro-fissures .

7. Age-related dehydration of the nucleus pulposus with loss of proteoglycans and water, reducing shock-absorbing capacity .

8. Acute trauma (e.g., falls, car accidents) causing sudden annular tears .

9. Whiplash injuries, from rapid neck hyperextension-flexion, disrupting annular integrity .

10. Poor posture and ergonomics, such as sustained neck flexion during desk work .

11. Prolonged static positions (e.g., sitting at a computer) increasing intradiscal pressure .

12. Obesity, adding chronic axial load and stress on cervical discs .

13. Smoking, which reduces disc nutrition and accelerates degeneration .

14. Work-related psychosocial stress, contributing to muscle tension and altered biomechanics .

15. Whole-body vibration exposure (e.g., heavy machinery), causing repetitive microtrauma .

16. Degenerative osteophytes altering load distribution and inducing annular stress .

17. Repetitive neck movements in contact sports (football, wrestling), increasing annular wear .

18. Nutritional deficiencies hindering disc matrix repair and cell viability .

19. Inflammatory endplate changes (Modic type I), reflecting an inflammatory milieu that weakens annular fibers .

20. Progression of degenerative disc disease, where the stabilization phase increases stiffness and stress on remaining healthy disc tissue .

Diagnostic Tests for Cervical Internal Disc Disruption

Accurate diagnosis of IDD relies on a combination of history, physical exam, imaging, and provocative procedures:

1. Clinical history and pain mapping using questionnaires and diagrams to localize discogenic pain .

2. Spurling’s test: axial compression with extension and rotation to reproduce radicular pain .

3. Neck distraction test: reduction of radicular symptoms with axial traction confirms nerve root or discogenic origin .
