Cervical C5–C6 Vertical Herniation

Vertical herniation of the C5–C6 intervertebral disc refers to displacement of disc material along the cranio-caudal (vertical) axis at the fifth cervical to sixth cervical vertebral junction. Unlike the more common posterolateral bulges, vertical migration can impinge on adjacent neural structures both above and below the disc space. This article provides comprehensive, evidence-based definitions, detailed anatomy, classification of herniation types, 20 causes, 20 clinical features, and 20 diagnostic modalities—with each topic explored in its own paragraph for clarity and depth.

Anatomy of the C5–C6 Motion Segment

Structure & Location

The C5–C6 motion segment comprises the inferior articulating surface of the C5 vertebral body, the superior surface of C6, the intervening intervertebral disc, bilateral facet (zygapophyseal) joints, and supporting ligaments. This segment lies in the middle third of the cervical spine, just above the C6–C7 level. It endures significant flexion, extension, and rotation, making it prone to degenerative changes.

Origin & Insertion of Key Ligaments

The anterior longitudinal ligament (ALL) spans from the basilar part of the occiput down to the anterior sacrum, firmly attaching along the anterior surfaces of C5 and C6 vertebral bodies and interposed disc. Posteriorly, the posterior longitudinal ligament (PLL) courses within the vertebral canal, attaching to the posterior margins of C5 and C6 and their disc. The ligamentum flavum connects the laminae of adjacent vertebrae, including C5 to C6, forming a continuous elastic sheet.

Blood Supply

The C5–C6 segment is vascularized primarily by paired vertebral arteries ascending through the transverse foramina of C6 up to C1. Small nutrient branches penetrate each vertebral body and disc. Additionally, the ascending cervical and deep cervical arteries (branches of the thyrocervical trunk) supply peri-vertebral soft tissues, including ligaments and neural arches.

Nerve Supply

Sensory innervation of the C5–C6 disc and adjacent structures arises from the sinuvertebral (recurrent meningeal) nerves, branches of the ventral rami of C5 and C6 nerve roots. These nerves re-enter the spinal canal to innervate the posterior annulus fibrosus, PLL, and periosteum, mediating pain when herniation or inflammation occurs.

Functions (Key Roles)

1. Load Transmission
   The C5–C6 disc absorbs compressive forces during axial load, distributing them evenly across the vertebral endplates to protect bony surfaces.

2. Flexion–Extension Mobility
   It permits approximately 15°–20° of flexion and extension at this motion segment, critical for neck movement.

3. Rotational Stability
   Through its annular fibers and facet joints, it limits excessive rotation to about 8° on each side, preventing neural injury.

4. Shock Absorption
   The nucleus pulposus acts hydrostatically to cushion sudden impacts, protecting the spinal cord and nerve roots.

5. Intervertebral Spacing
   Maintains foraminal height to allow unobstructed exit of the C6 nerve roots bilaterally.

6. Proprioception
   Mechanoreceptors within the annulus convey position sense, coordinating neck and head movements.

Types of Herniation

Disc Bulge

A broad-based extension of the disc circumference beyond the vertebral margins, typically involving >25% of the disc edge. Bulges rarely migrate far from the disc space.

Disc Protrusion

Focal herniation in which the base (point of attachment) is wider than the displaced disc material. Protrusions at C5–C6 may indent the thecal sac but often remain contained within annular fibers.

Disc Extrusion

Here the herniated nucleus pulposus breaches the annulus fibrosus, forming a fragment whose diameter exceeds its connection to the parent disc. Vertical extrusion can travel superiorly or inferiorly into adjacent vertebral levels.

Disc Sequestration

A subtype of extrusion in which the detached fragment loses continuity entirely and migrates freely within the spinal canal. Sequestrations may ascend or descend multiple levels at C5–C6.

Superior (Upward) Vertical Herniation

Migration of extruded or sequestrated material into the cranial epidural space above the C5–C6 disc, potentially compressing the C5 nerve root or the spinal cord at the C4–C5 level.

Inferior (Downward) Vertical Herniation

Descent of disc material into the caudal epidural space below C5–C6, impinging upon the C6 nerve root or narrowing the C6–C7 neural foramen.

Causes

1. Age-Related Degeneration
   With advancing age, proteoglycan loss in the nucleus reduces water content, weakening annular lamellae and predisposing to tears that facilitate vertical migration of disc material.

2. Repetitive Neck Flexion
   Chronic forward-flexed postures (e.g., desk work) amplify compressive stress on the anterior annulus, promoting fissure formation and eventual extrusion.

3. Acute Traumatic Injury
   Whiplash or heavy load impact can produce a sudden increase in intradiscal pressure, causing disc material to herniate vertically past annular restraints.

4. Genetic Collagen Disorders
   Mutations in COL2A1 or COL9A2 genes impair collagen fiber integrity in the annulus fibrosus, reducing resistance to vertical displacement.

5. Smoking
   Nicotine and other toxins reduce endplate perfusion, accelerating disc degeneration and weakening annular fibers against vertical stresses.

6. Obesity
   Excess body mass increases axial load on cervical discs during activities, contributing to annular micro-tears and vertical migration risk.

7. Poor Ergonomics
   Non-adjustable workstations that hyperextend or flex the neck place uneven stresses on C5–C6, initiating annular failure.

8. Occupational Vibration
   Use of jackhammers or power tools transmits oscillatory forces, disrupting disc hydration and fiber orientation, facilitating vertical herniation.

9. High-Impact Sports
   Football tackles or gymnastics landing strains can overwhelm annular lamellae acutely, pushing nucleus through the disc space vertically.

10. Inflammatory Disc Disease
    Autoimmune or inflammatory processes degrade disc matrix enzymes, weakening annular structure against vertical protrusion.

11. Poor Posture in Youth
    Adolescent “text neck” habits can set the stage for early annular micro-damage, predisposing to vertical disc extrusion later.

12. Connective Tissue Disorders
    Ehlers–Danlos syndrome features hypermobile joints and fragile ligaments, including the PLL and annulus, facilitating vertical herniation.

13. Occupational Lifting
    Improper lifting techniques (axial loading with flexion) impose sudden vertical stress on the C5–C6 disc, causing annular failure.

14. Loss of Cervical Lordosis
    Straightening of the cervical curve concentrates stress at transitional levels like C5–C6, hastening annular tears.

15. Radiation Exposure
    Therapeutic radiation can damage disc cell viability and matrix components, weakening annular resistance to vertical migration.

16. Disc Endplate Calcification
    Calcified endplates reduce nutrient diffusion, accelerating degeneration and making vertical fissures more likely.

17. Repeated Microtrauma
    Frequent minor injuries accumulate annular damage over time, eventually leading to vertical herniation.

18. Metabolic Disorders
    Diabetes and hyperlipidemia alter disc cell metabolism, diminishing matrix repair and resilience.

19. Hypermobility Syndromes
    Excessive motion at C5–C6 strains annular fibers repetitively, lowering threshold for vertical extrusion.

20. Congenital Vertebral Anomalies
    Klippel–Feil fusion or hypoplastic pedicles can alter load distribution, stressing the adjacent C5–C6 disc vertically.

FAQs

1. What causes C5–C6 vertical herniation?
   Repeated loading, age-related degeneration, trauma, genetics, poor posture, smoking, obesity, heavy lifting, vibration exposure, inflammatory conditions, metabolic disorders, microtrauma, occupational strain, congenital disc weakness, spinal instability, dehydration, corticosteroid overuse, poor nutrition, rheumatoid disease, and infection.

2. Is it different from a typical disc herniation?
   Yes—vertical herniation intrudes into the vertebral body endplate rather than horizontally into the spinal canal.

3. Can it heal on its own?
   Mild cases often improve with conservative care (traction, therapy) over 6–12 weeks.

4. How is it diagnosed?
   MRI is gold standard; CT and X-rays can show Schmorl’s nodes; discography in select cases.

5. Does it cause arm pain?
   If nucleus material irritates exiting nerve roots at C6, pain, tingling, or weakness may radiate into the thumb and index finger.

6. Are there exercise risks?
   Aggressive extension or axial loading can worsen protrusion; always follow a guided program.

7. What’s the role of steroids?
   Short-term oral or epidural steroids reduce inflammation but don’t repair the disc.

8. Do supplements really work?
   Evidence for glucosamine, chondroitin, and collagen shows modest symptomatic relief; structural changes less proven.

9. Is surgery always needed?
   No—over 90 percent improve with non-surgical care; surgery is reserved for neurological deficits or intractable pain after 3–6 months.

10. Can vertical herniation recur?
    Yes—especially if underlying degenerative factors persist; prevention is key.

11. What’s the recovery time after ACDF?
    3–6 months for bone fusion; many return to light work by 4–6 weeks.

12. Are stem cells safe?
    Early trials show promise but long-term safety and efficacy require more research.

13. Does smoking affect healing?
    Smoking reduces blood flow and impairs cell repair—quitting improves outcomes.

14. What lifestyle changes help?
    Ergonomics, weight loss, smoking cessation, balanced nutrition, and regular exercise.

15. How often should I follow up?
