Article Summary

A posterolateral herniated cervical intervertebral disc occurs when the soft inner core (nucleus pulposus) of a cervical disc bulges out through a tear in the tougher outer ring (annulus fibrosus) toward the back and side of the spinal canal. This posterolateral protrusion can press on nearby spinal nerves or the spinal cord itself, leading to pain, numbness, tingling, or weakness in the neck, shoulders, arms,...

Definition

A posterolateral herniated cervical intervertebral disc occurs when the soft inner core (nucleus pulposus) of a cervical disc bulges out through a tear in the tougher outer ring (annulus fibrosus) toward the back and side of the spinal canal. This posterolateral protrusion can press on nearby spinal nerves or the spinal cord itself, leading to pain, numbness, tingling, or weakness in the neck, shoulders, arms, and hands Mayo ClinicNCBI.

Anatomy of the Cervical Intervertebral Disc

Structure & Location
- Cervical discs lie between the vertebral bodies from C2–C3 down to C7–T1.
- Each disc has an inner gel-like nucleus pulposus surrounded by a fibrous annulus fibrosus, and sits between the superior endplate of one vertebra and the inferior endplate of the one above Mayo ClinicPhysiopedia.
Origin & Insertion
- Unlike muscles, discs “attach” directly to the vertebral endplates above and below via collagen fibers in the annulus fibrosus that anchor into the bony plates Radiology Assistant.
Blood Supply
- Discs are largely avascular; nutrition reaches the inner nucleus pulposus by diffusion through the vertebral endplates from small arteries (metaphyseal arteries) in the adjacent vertebrae.
- The outer annulus may receive tiny blood vessels from surrounding vertebral branches Mayo Clinic.
Nerve Supply
- The sinuvertebral nerve (recurrent meningeal branch) supplies pain fibers to the outer annulus fibrosus.
- Some fibers also come from adjacent spinal nerve roots NCBI.
Six Functions
1. Shock Absorption: Cushions forces between vertebrae.
2. Load Distribution: Spreads out weight evenly across endplates.
3. Spinal Stability: Helps maintain the correct spacing and alignment of vertebrae.
4. Flexibility & Motion: Allows bending, twisting, and stretching of the neck.
5. Height Maintenance: Keeps the normal distance between vertebrae for nerve passageways.
6. Protects Spinal Cord and Nerves: Acts as a buffer to prevent bone-to-nerve contact Mayo ClinicRadiology Assistant.

Types of Disc Herniation

Posterolateral cervical herniations fall into four main categories based on how far the nucleus pulposus extends:

Bulging: The disc margin extends beyond its normal boundary but the annulus remains intact.
Protrusion: The nucleus pushes into the annulus, causing a small tear, but the annulus’s outer layer holds it in place.
Extrusion: Nuclear material breaks through the annular fibers but stays connected to the disc.
Sequestration: A fragment of disc material breaks free and can migrate within the spinal canal PhysiopediaVerywell Health.
