Cervical Subligamentous Vertical Herniation

A cervical subligamentous vertical herniation is a subtype of cervical disc extrusion in which nucleus pulposus material breaches the annulus fibrosus but remains contained beneath the posterior longitudinal ligament (PLL), migrating cranially or caudally along its subligamentous plane. This focal extrusion often produces pronounced neural compression—either of exiting nerve roots in the neural foramina or of the spinal cord within the canal—leading to radiculopathic or myelopathic symptoms.


Anatomy of the Posterior Longitudinal Ligament (PLL)

Structure & Location

The PLL is a continuous fibrous band situated within the vertebral canal, immediately posterior to the vertebral bodies. It attaches firmly to the posterior aspects of vertebral bodies and more loosely over intervertebral discs, extending from the body of the axis (C2) superoinferiorly to the sacrum. In the cervical spine, it overlaps the C2–C3 through C7–T1 disc spaces, guiding extruded disc material along its subligamentous plane. RadiopaediaWikipedia

Origin & Insertion

  • Superficial fibers span multiple vertebral levels (3–4 segments), originating at C2 and inserting broadly down to the sacrum.

  • Deep fibers connect adjacent vertebrae directly, anchoring firmly at the margins of individual vertebral bodies.
    The ligament narrows gradually from thoracic to lumbar regions, reflecting functional demands. Wikipedia

 Blood Supply

Vascularization arises from ventral (anterior) branches of the segmental spinal arteries, which enter the canal via intervertebral foramina and give off small nutrient branches to the PLL and adjacent epidural tissues. In the cervical region, contributions come primarily from the vertebral and ascending cervical arteries.

Nerve Supply

Innervated by the sinuvertebral (recurrent meningeal) nerves, which branch from the ventral rami of the spinal nerves, re-enter the canal through the intervertebral foramina, and supply the posterior annulus fibrosus, PLL, and dura mater. These nerves mediate pain and proprioceptive signals from the ligament.

Functions

  1. Limits hyperflexion: Resists excessive forward bending of the spine.

  2. Reinforces disc integrity: Supports the posterior annulus, reducing bulge formation.

  3. Contains herniations: Holds extruded nuclear material within its subligamentous space.

  4. Maintains alignment: Stabilizes intervertebral alignment by tethering vertebral bodies.

  5. Proprioception: Conveys positional feedback via rich sensory innervation.

  6. Spinal canal protection: Serves as a barrier between disc material and neural elements. Wikipedia


Types of Intervertebral Disc Herniation

Disc herniations are classified by the relationship of the nucleus to the annulus and PLL, and by fragment migration:

  1. Disc Bulge (Protrusion): Diffuse, symmetric extension of the annulus without annular rupture; nucleus remains within an intact annulus.

  2. Focal Protrusion: Localized annular deformation with a broad base (>25% of disc circumference) but intact outer annulus.

  3. Disc Extrusion: Nuclear material breaches the annulus fibrosus; base width narrower than the extruded material. If contained under the PLL and migrating vertically, it is termed a subligamentous vertical herniation.

  4. Transligamentous Extrusion: Nuclear material extends beyond the PLL into the epidural space, with the PLL torn.

  5. Sequestration (Free Fragment): Extruded fragment loses continuity with the parent disc and migrates freely in the spinal canal or neural foramen.


Causes of Cervical Subligamentous Vertical Herniation

  1. Age‐related Degeneration: Disc desiccation and proteoglycan loss reduce internal pressure buffering, increasing annulus susceptibility to tears.

  2. Acute Trauma: Falls or motor vehicle collisions can generate sudden high intradiscal pressure, causing annular rupture.

  3. Repetitive Microtrauma: Chronic cervical flexion or vibration (e.g., heavy machinery operators) leads to cumulative annular fiber fatigue.

  4. Poor Lifting Mechanics: Improper lifting with the neck flexed increases shear forces on cervical discs.

  5. Genetic Predisposition: Polymorphisms in collagen (COL1A1), aggrecan, and MMP genes predispose to disc degeneration and herniation.

  6. Smoking: Nicotine‐induced vasoconstriction impairs nutrient diffusion to discs, accelerating degeneration.

  7. Obesity: Excess body weight increases axial loading, raising intradiscal pressure in the cervical spine.

  8. Sedentary Lifestyle: Reduced spinal mobility and core muscle weakness compromise spinal support.

  9. Occupational Hazards: Prolonged cervical flexion in desk work or driving increases risk.

  10. High‐impact Sports: Contact sports (football, rugby) and gymnastics impose repetitive spinal loading.

  11. Hypermobility Disorders: Ehlers–Danlos syndrome and other connective tissue disorders weaken annular integrity.

  12. Inflammatory Arthritis: Rheumatoid arthritis can erode disc margins and adjacent ligaments.

  13. Diabetes Mellitus: Advanced glycation end‐products accelerate matrix degradation in the annulus.

  14. Corticosteroid Use: Systemic steroids may weaken connective tissue and impair disc healing.

  15. Poor Posture: Forward head posture shifts load anteriorly, stressing posterior annulus.

  16. Disk Dehydration: Reduced water content lowers disc height and increases focal disc stress.

  17. Endplate Microfractures: Vertebral endplate damage allows nucleus material to penetrate into subligamentous space.

  18. Cervical Spine Surgeries: Previous discectomy or fusion alters biomechanics, predisposing adjacent levels to herniation.

  19. Ligamentous Laxity: Genetic or acquired attenuation of PLL may permit easier subligamentous migration. Wikipedia

  20. Vertebral Osteophytes: Bone spurs can create focal stress risers on adjacent disc annulus.

When to See a Doctor

  • Routine Check: Persistent neck discomfort > 6 weeks despite home measures or worsening symptoms.


Frequently Asked Questions

  1. What exactly is “vertical” herniation?
    Vertical herniation means the disc’s inner gel pushes up or down through a tear in its outer ring, pressing on nerves in the subarticular zone beneath the facet joint.

  2. How does subarticular pressure cause arm pain?
    When the herniated disc enters the subarticular zone, it narrows the foramen (nerve exit), compressing the nerve root and causing radiating pain, numbness, or weakness down the arm.

  3. Can I recover without surgery?
    Most mild-to-moderate cases improve with non-surgical treatments—physical therapy, pain medications, and lifestyle changes—over 6–12 weeks.

  4. How soon should I stop heavy lifting?
    Immediately halt any activity that aggravates neck pain; wait until a healthcare provider clears you, often after pain subsides and strength returns.

  5. Is traction safe at home?
    Only use traction under professional guidance. Incorrect setup can worsen symptoms or strain other structures.

  6. Will massage help my herniation?
    Targeted myofascial release or trigger-point therapy can ease muscle tension but won’t repair the disc itself.

  7. Do supplements really work?
    Supplements like glucosamine or curcumin can support cartilage health and reduce inflammation, but they’re adjuncts—not sole treatments.

  8. What are the risks of cervical steroid injections?
    Low: temporary pain flare, infection, or rare nerve injury. Benefits often outweigh risks for persistent radicular pain.

  9. When is fusion preferred over artificial disc?
    Fusion is chosen when instability exists or arthritis is severe; disc replacement suits younger patients wanting motion preservation.

  10. Can stem cells regrow a damaged disc?
    Early studies show promise: injected stem cells may differentiate and secrete repair factors, but long-term human data are still emerging.

  11. How do I sleep with neck pain?
    Use a cervical-contour pillow, sleep on your back, and avoid stomach positions that hyperextend the neck.

  12. Is posture the main cause of herniation?
    Poor posture contributes but so do age-related disc degeneration, genetics, and acute injuries.

  13. How long for nerve recovery?
    Nerves heal slowly; arm symptoms may improve over months once compression is relieved.
