An internal disc disruption at the C2–C3 level refers to damage within the intervertebral disc—specifically, fissuring of the annulus fibrosus and distortion of the nucleus pulposus—without overt herniation of disc material beyond its normal boundary. This lesion can be a source of chronic neck pain and segmental instability. Physiopedia
Anatomy of the C2–C3 Intervertebral Disc
Structure & Location
The intervertebral disc between the second (C2) and third (C3) cervical vertebrae is a fibrocartilaginous joint that cushions and stabilizes the spine. It sits directly between the odontoid process of C2 and the body of C3, forming a cartilaginous junction that permits flexion, extension, rotation, and lateral bending. NCBI
Origin & Insertion
-
Origin: Annulus fibrosus fibers attach peripherally to the roughened rim (epiphyseal ring) of the C2 vertebral body.
-
Insertion: These fibers continue to insert on the epiphyseal ring of C3, encircling the nucleus pulposus centrally.
Blood Supply
-
Discs are largely avascular centrally.
-
Peripheral annulus fibers receive tiny branches from the ascending cervical arteries. Nutrients diffuse inward through endplate capillaries. Medscape
Nerve Supply
-
Pain fibers (nociceptors) enter at the disc’s outer third via the sinuvertebral nerves (recurrent meningeal branches of the spinal nerves).
-
At C2–C3, these derive from the C3 spinal nerve root.
Key Functions
-
Load Distribution: Evenly transmits axial loads across C2–C3.
-
Shock Absorption: Dampens forces from head movement and impact.
-
Motion Facilitation: Allows controlled flexion/extension, rotation, and lateral bending.
-
Intervertebral Spacing: Maintains foraminal height to protect nerve roots.
-
Spinal Stability: Works with ligaments to resist excessive motion.
-
Growth & Remodeling: In younger individuals, contributes to vertebral growth plate activity.
Types of Internal Disc Disruption
-
Radial Tear – Fissure from nucleus toward exterior.
-
Concentric Tear – Layers of annulus separate in a circular pattern.
-
Transverse Tear – Split across lamellae of the annulus.
-
Circumferential Tear – Complete circular separation around the nucleus.
-
Combined Tears – Features of more than one tear pattern present.

Frequently Asked Questions
-
What is internal disc disruption?
Damage to the inner disc without bulging/herniation. -
How is it different from herniation?
No disc material protrudes beyond the annulus. -
Can IDD heal on its own?
Mild cases may improve with rehab and lifestyle change. -
Is surgery always needed?
No—most respond to non-operative management. -
Does discography confirm IDD?
It can provoke symptoms but carries risks (infection). -
Are injections helpful?
Targeted steroid or biologic injections may reduce pain. -
Can IDD cause arm pain?
Yes, if inflammation irritates adjacent nerve roots. -
What lifestyle changes help?
Ergonomics, smoking cessation, weight control. -
Are supplements effective?
Some (glucosamine, collagen) support disc health. -
Is activity restriction recommended?
Short-term rest, then gradual return to activity. -
Can IDD lead to arthritis?
Chronic instability may accelerate facet joint degeneration. -
Is an MRI definitive?
It shows structural changes but not always pain source. -
What is the recovery timeline?
6–12 weeks for non-surgical treatment response. -
Does age matter?
Younger discs heal better; degeneration increases with age. -
How to prevent recurrence?
Ongoing exercise, posture vigilance, healthy lifestyle..
