Cervical non-contained disc compression collapse is a severe form of cervical disc injury in which the inner gel-like material (nucleus pulposus) breaks through the tough outer ring (annulus fibrosus), escapes into the spinal canal, and leads to loss of disc height (collapse). This non-contained herniation can press directly on nerve roots or the spinal cord, causing pain, weakness, and potential neurological deficits Johnson ChiropracticSpine & Orthopedic Center.
Anatomy
Understanding this condition requires familiarity with cervical disc anatomy and its relationship to surrounding structures.
Structure & Location
Intervertebral discs sit between adjacent cervical vertebrae (C2–C7), acting as shock absorbers and allowing neck movement.
Each disc has two parts: a tough outer annulus fibrosus and a soft inner nucleus pulposus NCBIWikipedia.
Origin & Insertion
Discs are anchored above and below to the vertebral endplates, which are thin layers of cartilage and bone covering each vertebral body Verywell Health.
The annulus fibrosus fibers insert into these endplates, securing the disc in place.
Blood Supply
In adults, discs are largely avascular. Small capillaries near the vertebral endplates and the outer annulus deliver nutrients by diffusion NCBIOrthobullets.
Nerve Supply
The sinuvertebral (recurrent meningeal) nerve innervates the outer one-third of the annulus fibrosus and nearby ligaments, allowing pain sensation when the annulus is torn Orthobullets.
Key Functions
Shock Absorption: The gel-like nucleus distributes compressive loads evenly.
Flexibility: Allows flexion, extension, lateral bending, and rotation.
Stability: Maintains vertebral alignment and spacing.
Protects Nerves: Keeps the neural foramen open for nerve roots.
Load Distribution: Spreads hydraulic pressure across the disc.
Weight Bearing: Supports the head’s weight and dynamic forces Wikipedia.
Types
Non-contained cervical disc injuries can be classified by the extent of herniation and fragment behavior:
Disc Extrusion: The nucleus breaches the annulus but remains connected to the disc NJ Spine & Orthopedic.
Sequestration: A fragment of nucleus pulposus breaks off completely and may migrate within the canal Verywell Health.
Collapsing Disc Height: Chronic degeneration leads to loss of disc space and ‘collapsed’ appearance Integrity Spine & Orthopedics.
Compression Collapse: In severe cases, disc collapse contributes to spinal cord compression (myelopathy) Home.
