Cervical Disc Derangement

Cervical disc derangement refers to any abnormal displacement, disruption, or degeneration of the intervertebral discs in the neck (cervical spine), including bulging, protrusion, extrusion, sequestration, internal disruption, and degenerative disc disease. These conditions may compress spinal nerves or the spinal cord, leading to neck pain, radiculopathy (nerve root symptoms), or myelopathy (spinal cord dysfunction) NCBIMedscape.

Cervical disc derangement refers to disruption of the normal anatomy of the intervertebral disc in the neck. Each disc consists of a soft, gelatinous center (nucleus pulposus) surrounded by a tough outer ring (annulus fibrosus). When the annulus weakens or tears—due to age-related wear and tear, injury, or repetitive strain—the nucleus can bulge or herniate, pressing on nearby nerves or the spinal cord. This derangement can cause neck pain, arm pain (radiculopathy), numbness, or weakness, and in severe cases, spinal cord dysfunction (myelopathy). It most often affects adults aged 30–50 and can arise from poor posture, heavy lifting, or degenerative changes over time NCBIPMC.

Anatomy of the Cervical Intervertebral Disc

Structure and Location

Each cervical intervertebral disc lies between the vertebral bodies of C2–C3 through C6–C7. It forms a fibrocartilaginous symphysis, consisting of an outer annulus fibrosus—a tough ring of concentric lamellae of collagen fibers—and an inner nucleus pulposus, which is a gel-like center that resists compressive forces and provides flexibility to the cervical spine KenhubWikipedia.

Attachment (Origin and Insertion)

The disc adheres firmly via its ring apophyses to the vertebral endplates above and below. This attachment is through fibrocartilaginous interfaces on the superior and inferior surfaces of each disc, anchoring it to the bony vertebral bodies and allowing force transmission while maintaining disc position Kenhub.

Blood Supply

In adults, intervertebral discs are largely avascular. Nutrient supply reaches the outer annulus fibrosus and the cartilaginous endplates via diffusion from segmental arteries—principally the vertebral, ascending cervical, and costocervical trunk branches. This limited vascular access contributes to poor disc healing capacity NCBISpine-health.

Nerve Supply

Sensory innervation of the outer annulus fibrosus and posterior longitudinal ligament is provided by the sinuvertebral (recurrent meningeal) nerves, which derive from the ventral ramus of spinal nerves and sympathetic rami communicantes. These nociceptive fibers transmit pain signals when the disc is injured or inflamed KenhubPMC.

Function 

Shock Absorption

The nucleus pulposus distributes axial loads evenly across the disc and adjacent vertebral bodies. Its high water content allows it to absorb compressive forces, preventing stress concentrations that could damage vertebrae or endplates Kenhub.

Flexibility and Movemen

The deformable nature of the disc permits flexion, extension, lateral bending, and limited rotation between vertebrae, contributing to the overall range of motion of the cervical spine and facilitating head movements Kenhub.

Load Transmission

Discs transmit compressive and shearing forces between adjacent vertebrae, stabilizing the spinal column during upright posture and movement, while allowing controlled mobility Kenhub.

Height Maintenance

By maintaining disc height, cervical discs ensure adequate intervertebral spacing, preserving foraminal dimensions for nerve roots and contributing to overall neck length and posture Wikipedia.

Joint Stability

The annulus fibrosus and associated ligaments form a stable fibrous joint (symphysis) that binds vertebrae together, preventing excessive motion that could compromise spinal cord integrity Kenhub.

Protection of Neural Elements

By providing a shock-absorbing and spacing function, discs protect the spinal cord and exiting nerve roots from compressive and shear forces during dynamic neck activities Kenhub.

Types of Cervical Disc Derangement

1. Disc Bulge – A circumferential extension of the disc beyond its normal boundary without disruption of the annulus fibrosus. Bulges involve more than 25% of the disc circumference and may encroach on neural structures .

2. Disc Protrusion – A focal outpouching of the disc wherein the base of the protruded material is wider than its depth. Protrusions maintain annular continuity but can compress adjacent nerve roots .

3. Disc Extrusion – The nucleus pulposus extends through a tear in the annulus fibrosus but remains connected to the parent disc by a disc tissue “neck.” Extruded fragments often impinge on neural elements .

4. Sequestration – A free fragment of nucleus pulposus breaks completely away from the parent disc and can migrate within the spinal canal, potentially causing acute radiculopathy or myelopathy .

5. Internal Disc Disruption – Annular fissures or tears within the disc without external displacement of disc material. These tears can allow inflammatory mediators to sensitize nociceptors, causing discogenic pain Medscape.

6. Degenerative Disc Disease (DDD) – An age-related process marked by loss of water content, disc height reduction, annular weakening, and osteophyte formation. DDD may lead to bulging, protrusion, or fissuring of the disc Wikipedia.
