Cervical Internal Disc Subarticular Disruption

Cervical Internal Disc Subarticular Disruption (CIDD-S) is a variant of internal disc disruption (IDD) occurring in the cervical spine. In IDD, the nucleus pulposus degrades and radial or concentric fissures form in the annulus fibrosus without external disc deformation . The subarticular subtype refers specifically to annular fissuring in the subarticular zone—the lateral recess just anterior to the facet joint—where escaping nuclear material can irritate nerve roots .

Anatomy

Structure & Location

• Intervertebral Disc: Lies between adjacent vertebral bodies C2–C3 through C6–C7, comprising an outer annulus fibrosus (laminated fibrocartilage) and an inner nucleus pulposus (gelatinous core) .

• Subarticular Zone: Lateral to the central canal, directly anterior to the facet joint, forming the part of the lateral recess where exiting nerve roots pass .

Origin & Insertion

• Cartilaginous Endplates: The annulus fibrosus attaches superiorly and inferiorly to hyaline cartilage endplates on the vertebral bodies, anchoring the disc and transmitting load .

Blood Supply

• Avascular: After early childhood, discs lose direct vessels. The outer one-third of the annulus receives scant branches from the posterior longitudinal ligament; the rest relies on passive diffusion of nutrients (oxygen, glucose) and metabolites across the cartilaginous endplates from vertebral body capillaries .

Nerve Supply

• Sinuvertebral (Recurrent Meningeal) Nerves: Branches of the dorsal root ganglia and ventral rami innervate only the outer one-third of the annulus fibrosus. No innervation reaches the inner annulus or nucleus in healthy discs .

Key Functions

1. Shock Absorption: Dampens axial and multidirectional loads to protect vertebrae and neural tissues ncbi.nlm.nih.gov.

2. Load Distribution: The nucleus pulposus transmits hydraulic pressure evenly, reducing stress concentration en.wikipedia.org.

3. Facilitation of Motion: Permits flexion, extension, lateral bending, and rotation jospt.org.

4. Maintenance of Disc Height: Preserves intervertebral space for nerve root passage physio-pedia.com.

5. Neural Protection: Sustains foraminal and canal dimensions to safeguard the spinal cord and nerve roots .

6. Spinal Stability: The annulus fibrosus acts as a ligament, uniting vertebral bodies en.wikipedia.org.

Diagnostic Tests (Long Descriptions)**

1. Patient History
   Detailed history gathers onset, aggravating/relieving factors, trauma, occupational risks, and prior interventions to focus evaluation.

2. Physical Exam
   Inspection of posture and muscle bulk, palpation for tenderness, and observation of cervical alignment.

3. Spurling’s Test
   With the neck in extension and lateral bending toward the symptomatic side, axial compression is applied. Reproduction of radicular arm pain has high specificity for cervical nerve root compression .

4. Shoulder Abduction Relief Test
   The patient lifts the affected arm and places the hand on the head. Relief of radicular pain suggests C5–C6 root involvement .

5. Range of Motion Measurement
   Goniometric or inclinometer assessment of flexion, extension, lateral flexion, and rotation quantifies functional loss.

6. Neurological Exam
   Systematic testing of motor strength (especially C5–C7 myotomes), sensory modalities (pinprick, light touch), and deep tendon reflexes.

7. MRI (T2-weighted)
   Gold standard imaging: visualizes annular fissures as high‐intensity zones, disc dehydration (“black disc”), paraspinal muscle changes, and nerve root compression .

8. CT Scan
   Superior for bony detail: shows osteophytes, calcified annular tears, and facet joint arthropathy.

9. Plain Radiographs
   Flexion‐extension lateral views identify segmental instability; neutral AP and lateral films assess disc space narrowing.

10. Provocative Discography
    Under fluoroscopic guidance, contrast is injected into the disc. Concordant pain reproduction plus visualization of fissure filling confirms symptomatic IDD .

11. CT Discogram
    Post‐discography CT provides fine detail of tear location and annular defect size.

12. High-Intensity Zone (HIZ) Sign
    A discrete bright signal on T2 MRI within the posterior annulus correlates strongly with granulation tissue and painful annular fissures .

13. Electromyography (EMG)
    Needle EMG evaluates denervation in affected myotomes to confirm radiculopathy and rule out peripheral neuropathy.

14. Nerve Conduction Studies (NCS)
    Quantifies conduction velocity and amplitude to differentiate root from peripheral nerve lesions.

15. Lhermitte’s Sign
    Neck flexion–induced electric shock sensation down the spine indicates possible cord involvement.

16. Hoffmann’s Sign
    Flicking the distal phalanx of the middle finger causes flexion of the thumb and index finger, suggesting cervical myelopathy.

17. Babinski Sign
    Upgoing plantar response on foot stimulation indicates an upper motor neuron lesion.

18. Vertebral Artery Test
    Careful head rotation and extension assess vertebrobasilar insufficiency prior to any manual therapy.

19. Functional Capacity Evaluation
    Standardized tests (lifting, carrying) gauge the patient’s ability to perform work‐related tasks safely.

20. Somatosensory Evoked Potentials (SSEP)
    Measures dorsal column conduction; useful when cord pathology is suspected.

Frequently Asked Questions

1. What causes CIDSD?

   • Repeated neck strain, poor posture, age-related disc wear, or sudden injury can lead to tiny tears inside the disc.

2. Is CIDSD the same as a herniated disc?

   • Not exactly. CIDSD is early internal tearing without full nucleus extrusion, while herniation means nucleus material pushes through the annulus.

3. Can CIDSD heal on its own?

   • Mild cases may improve with rest, exercises, and posture correction over weeks to months.

4. How is CIDSD diagnosed?

   • MRI is the best tool to visualize internal disc tears and nerve involvement.

5. Will I need surgery?

   • Most patients avoid surgery by using non-drug therapies and medications; surgery is only if severe nerve compression or persistent pain.

6. How long does recovery take?

   • With proper care, many improve in 6–12 weeks; advanced therapies or surgery may extend recovery.

7. Can I work with CIDSD?

   • Often yes. Modifying activities, ergonomics, and therapy can let you work comfortably.

8. Are there long-term effects?

   • Untreated CIDSD can progress to herniation or chronic neck pain, so early management is key.

9. Do supplements really help?

   • Some, like glucosamine and fish oil, may support disc repair and reduce inflammation, but they’re best as part of a full plan.

10. Is massage safe?

    • Yes, when done gently by a trained therapist, massage can ease muscle tightness without harming the disc.

11. What posture is best for sleep?

    • Sleeping on your back with a neck-contour pillow keeps your spine neutral.

12. Can exercise ever make it worse?

    • High-impact or poor-form activities can aggravate CIDSD; always use controlled, guided exercises.

13. How often should I do neck exercises?

    • Daily is ideal—short sessions (5–10 minutes) morning and evening help maintain mobility.

14. Will CIDSD come back?

    • It can recur if risk factors persist; ongoing posture care and exercises reduce this risk.

15. What’s the best first-line treatment?

    • Gentle stretching, heat and cold packs, posture correction, and over-the-counter NSAIDs usually start the healing process.

Cervical Internal Disc Subarticular Disruption is an early form of disc injury that can cause neck pain and nerve irritation. A combination of targeted non-drug therapies, appropriate medications, lifestyle changes, and, when needed, advanced biological treatments or surgery can lead to lasting relief. Early recognition, proper posture, and active management are key to preventing progression and enjoying a pain-free life.
