Prolapsed median cervical intervertebral disc—also known as a central cervical disc herniation—occurs when the jelly-like nucleus pulposus of one of the six cervical discs (C2–C3 through C7–T1) pushes centrally through the fibrous annulus fibrosus and into the spinal canal. This central protrusion can press on the spinal cord or its coverings, leading to neck pain, nerve irritation, and sometimes spinal cord dysfunction Wikipedia.
Anatomy
Structure
Each intervertebral disc is made of two main parts:
-
Annulus fibrosus: A tough, layered ring of fibrocartilage composed of concentric lamellae rich in type I collagen at its periphery and type II collagen more centrally. This structure provides tensile strength and contains the inner core.
-
Nucleus pulposus: A gel-like center high in water (70–90%), proteoglycans, and loose collagen fibers, acting as the primary shock absorber by evenly distributing compressive forces across the disc Wikipedia.
Location
Cervical discs sit between each pair of cervical vertebral bodies, from C2–C3 through C7–T1, forming cushions that account for about one-fourth of the total neck height. They fill the gap between vertebrae, allowing flexion, extension, rotation, and lateral bending of the head and neck Cleveland Clinic.
Origin and Insertion
Although discs are not muscles, their “attachments” can be described as:
-
Superior attachment: Cartilaginous endplate of the vertebral body above.
-
Inferior attachment: Cartilaginous endplate of the vertebral body below.
These endplates anchor the annulus fibrosus and help transmit loads to the vertebrae Wikipedia.
Blood Supply
In adults, intervertebral discs are avascular. During embryonic development and early life, small vessels penetrate the outer annulus and endplates, but these regress postnatally. Nutrients reach inner disc cells by diffusion through the cartilaginous endplates from adjacent vertebral capillaries Kenhub.
Nerve Supply
Disc pain is mediated mainly by the meningeal (sinuvertebral) nerves, which branch from the spinal nerve’s ventral ramus and a gray ramus communicans. These recurrent nerves re-enter the canal via the intervertebral foramen and innervate the outer annulus fibrosus, posterior longitudinal ligament, and dura, carrying both nociceptive and proprioceptive fibers PMC.
Functions
-
Shock absorption: The nucleus pulposus cushions vertical loads and sudden impacts, protecting vertebrae Deuk Spine.
-
Load distribution: Evenly disperses mechanical stress across vertebral endplates.
-
Spinal flexibility: Allows movements—flexion, extension, rotation, and lateral bending—by acting as pivot points.
-
Height maintenance: Helps maintain cervical height, preserving normal cervical lordosis.
-
Protective spacing: Keeps nerve roots and the spinal cord free from compression by maintaining intervertebral foraminal height.
-
Joint stabilization: Works with facet joints and ligaments to stabilize the cervical spine during movement NCBI.
Types of Cervical Disc Prolapse
-
Bulging disc: Symmetrical extension of annulus beyond endplates without rupture.
-
Protrusion: Focal herniation where the base width is wider than its protruding segment.
-
Extrusion: Nucleus material breaks through annulus but remains connected to parent disc.
-
Sequestration: Freed nucleus fragment migrates away from the disc.
-
Central (Median): Herniation directly into the midline of the spinal canal.
-
Paracentral: Slightly off-center toward one side, often compressing exiting nerve roots.
-
Foraminal: Herniation into the neural foramen, compressing the spinal nerve root.
-
Extraforaminal: Beyond the foramen, affecting the nerve as it exits the canal.

Intradural: Rare; disc material enters the dural sac.
-
Calcified: Chronic herniation with calcium deposition, making the fragment stiff.

FAQs
-
What is a median cervical disc prolapse?
A central herniation of the disc’s gel-like core into the spinal canal, which can press on the spinal cord and nerves Wikipedia. -
How is it different from a posterolateral herniation?
Posterolateral herniations occur off-center, usually affecting exiting nerve roots, while median herniations push directly into the central canal. -
What causes a disc to prolapse?
Usually a mix of age-related degeneration, repetitive stress, poor posture, and sometimes sudden injury. -
Which cervical levels are most often affected?
C5–C6 and C6–C7 are the most common sites due to high mobility and stress. -
Can it heal without surgery?
Many cases improve with conservative care—therapy, traction, and medications—over weeks to months. -
How is it diagnosed?
MRI is the gold standard, often supplemented by neurological exams and sometimes EMG. -
What non-drug treatments help?
Physical therapy, cervical traction, heat/cold, acupuncture, and posture training are very effective. -
When is surgery recommended?
For severe or progressive neurologic symptoms, myelopathy, or when conservative care fails over 6–12 weeks. -
Are all herniated discs symptomatic?
No—many people have asymptomatic herniations found incidentally on imaging. -
Can I work with a cervical disc prolapse?
Light duties with ergonomic adjustments are usually okay; heavy lifting or repetitive neck use should be limited. -
What exercises should I avoid?
Deep neck flexion under load, heavy overhead lifting, and rapid twisting movements may worsen the herniation. -
Will it recur after treatment?
Recurrence risk is low but present—continued preventive measures help reduce it. -
Is an artificial disc better than fusion?
Artificial discs preserve motion but have specific indications; fusion remains the gold standard for many patients. -
How long is recovery after surgery?
Most patients return to normal activities in 4–6 weeks, with full recovery by 3–6 months. -
Can lifestyle changes prevent recurrence?
Yes—maintaining posture, regular exercise, and ergonomic habits are key to long-term prevention.
