Cervical disc central extrusion is a type of herniated disc in the neck (“cervical”) region where the soft, gel-like center of an intervertebral disc (the nucleus pulposus) breaks through a tear in its tough outer ring (the annulus fibrosus) and pushes directly into the central spinal canal. This “extrusion” differs from a simple bulge (protrusion) because the inner material escapes past the boundaries of the disc but remains attached, potentially pressing on the spinal cord or nerve roots and causing pain or neurological symptoms RadiopaediaVerywell Health.
Anatomy of the Cervical Intervertebral Disc
-
Structure & Location:
Each cervical disc sits between two vertebral bodies (e.g., C5–C6) in the neck. Discs are fibrocartilaginous cushions composed of an outer annulus fibrosus (concentric collagen fibers) surrounding an inner nucleus pulposus (hydrated proteoglycan gel) WikipediaDeuk Spine. -
“Origin” & “Insertion”:
Unlike muscles, discs don’t “originate” or “insert.” Instead, the annulus fibrosus securely attaches to the upper and lower vertebral endplates, anchoring the disc in place. -
Blood Supply:
In adults, only the outer third of the annulus fibrosus and the cartilaginous endplates receive blood, via small branches from segmental arteries. The inner annulus and nucleus rely on diffusion for nutrients PubMedPhysiopedia. -
Nerve Supply:
Sensory nerve fibers (sinuvertebral nerves) innervate the outer annulus fibrosus. These nerves can transmit pain when the disc is injured or inflamed PubMedPhysiopedia. -
Functions:
-
Shock absorption: Distribute compressive forces evenly.
-
Load bearing: Support weight of head and neck.
-
Flexibility: Allow nodding, rotation, and lateral bending.
-
Stability: Maintain alignment of vertebrae.
-
Spacing: Preserve height of intervertebral foramina (nerve exits).
-
Hydraulic cushion: Maintain disc hydration and resilience RadiopaediaKenhub.
-
Types of Cervical Disc Herniation by Location
-
Central Extrusion: Material pushes straight back into spinal canal, risking cord compression.
-
Paracentral Extrusion: Slightly off-center, often impacting one side’s nerve roots.
-
Foraminal Herniation: Material enters the neural foramen, compressing exiting nerve roots.
-
Far Lateral (Extraforaminal): Disc fragment migrates outside the foramen, affecting dorsal root ganglia.
-
Sequestration: A free fragment completely detaches and may migrate within canal PMCInstituto Clavel. Centro de neurocirugía.
