Cervical internal disc posterolateral disruption (CID–PLD) is a form of internal disc disruption (IDD) in which the inner architecture of a cervical intervertebral disc—particularly its annulus fibrosus—is damaged in the posterolateral region without overt external herniation. In IDD, the nucleus pulposus (NP) degenerates or protrudes internally, creating fissures within the annulus that can distort disc biomechanics and generate pain through mechanical instability and chemical irritation of pain-sensitive structures. Unlike frank herniations, CID–PLD lacks an external bulge yet can produce significant neck and radicular symptoms due to annular tears, microstructural derangement, and inflammatory mediator release in the posterolateral quadrant of the disc Patient InfoMedscape Reference.
Anatomy
Structure
Each cervical intervertebral disc comprises two main components:
-
Nucleus pulposus (NP): A central, gelatinous core rich in water (≈90% at birth, ≈70% by age 60) and proteoglycans, providing hydrostatic pressure for load distribution.
-
Annulus fibrosus (AF): A multilamellar ring of type I collagen fibers interspersed with proteoglycans and elastic fibers that encircle the NP, resisting tensile stresses and containing the NP under load NCBINCBI.
Location
Cervical discs lie between the vertebral bodies from C2–C3 through C7–T1, making up about 25% of the cervical column’s height. There is no disc at the atlanto-occipital (occiput–C1) or atlanto-axial (C1–C2) joints Physiopedia.
Origin & Insertion
The cartilaginous endplates cap the superior and inferior surfaces of each disc, anchoring the AF circumferentially to adjacent vertebral bodies. These endplates provide the interface for nutrient diffusion but ossify and calcify with age, compromising disc nutrition over time ResearchGate.
Blood Supply
Intervertebral discs are the body’s largest avascular structures. Vessels supply only the bony endplates; all disc cells rely on diffusion of nutrients and removal of waste products through the endplates and outer AF ResearchGate.
Nerve Supply
Pain fibers of the sinuvertebral (recurrent meningeal) nerves, originating from the ventral rami of cervical spinal nerves, re-enter the spinal canal via the intervertebral foramina. They innervate primarily the outer one-third of the AF and adjacent ligaments, making annular tears particularly nociceptive PubMedRadiopaedia.
Functions
Intervertebral discs perform six key functions:
-
Load transmission: Distribute axial loads evenly across vertebral bodies.
-
Shock absorption: Attenuate forces during impact and movement.
-
Spinal flexibility: Permit controlled flexion, extension, lateral bending, and rotation.
-
Stability: Maintain intervertebral alignment and resist shear forces.
-
Intervertebral spacing: Preserve foraminal height for nerve root passage.
-
Nutrient diffusion: Facilitate metabolic exchange through endplates for disc cell viability Physiopedia.
Types of Internal Disc Disruption
-
Concentric fissures – Circular separations parallel to lamellae, usually confined to outer AF layers Radiopaedia.
-
Radial fissures – Tears extending from NP outward through the AF, perpendicular to concentric lamellae Radiopaedia.
-
Transverse fissures – Horizontally oriented splits in the outer AF, often peripheral manifestations of radial tears Radiopaedia.
-
High-Intensity Zone (HIZ) lesions – Hyperintense foci on T2-weighted MRI within the posterior AF, indicating granulation tissue ingrowth into fissures Fortune Journals.
-
Perinuclear tears (PNT) – Partial separations adjacent to the NP that do not span the full annular thickness Fortune Journals.
-
Transdiscal tears (TDT) – Fissures extending across cartilaginous endplates, linking NP to vertebral bodies Fortune Journals.
-
Rim lesions (RL) – Horizontal fissures at the disc periphery near endplates, increasing in frequency with age and disc levels involved Fortune Journals.
