A cervical annular tear (also called an annular fissure) is a crack or split in the annulus fibrosus, the tough outer ring of a cervical intervertebral disc. When this tear is central, it occurs in the very middle of the disc’s back wall; when paracentral, it lies just to the right or left of the center, but still toward the back of the disc. These tears weaken the disc’s structure and can allow painful inflammatory chemicals to irritate nearby nerves RadiopaediaNCBI.
Anatomy of the Cervical Annulus Fibrosus
Structure
The annulus fibrosus is made of 15–25 concentric rings (lamellae) of type I and II collagen, with fibers in each layer oriented about 60° to vertical, alternating directions in adjacent layers. This design gives great strength to resist compression, torsion, and bending WikipediaPhysiopedia.Location
Cervical discs lie between vertebrae from C2–3 down to C7–T1. The annulus forms the outer rim of each disc, surrounding the gel-like nucleus pulposus Wikipedia.Attachments (“Origin/Insertion”)
The outermost collagen fibers (Sharpey’s fibers) anchor into the bony vertebral endplates above and below, securing the disc to each vertebral body ChiroGeek.Blood Supply
In adults, the annulus is almost entirely avascular. Only the outer one-third of the outer lamellae receive tiny branches from the adjacent vertebral endplate vessels; nutrients otherwise diffuse by osmosis through the cartilage endplates PhysiopediaNCBI.Nerve Supply
Innervation comes via the sinuvertebral (recurrent meningeal) nerves to the outer lamellae only. Inner layers lack sensation. This is why only some annular tears cause pain Physiopedia.Functions
Shock absorption: Distributes compressive loads evenly.
Flexibility: Permits slight movements (flexion, extension, rotation).
Stability: Holds vertebrae together as a fibrous joint.
Containment: Keeps nucleus pulposus centered.
Pressure regulation: Maintains disc height and hydration.
Load sharing: Balances forces between anterior and posterior spinal elements Wikipedia.
Types of Cervical Annular Tears
Annular tears are classified by orientation and location:
By orientation (how the fibers split) RadiopaediaNCBI:
Radial tears: Start at the nucleus and extend outward.
Concentric tears: Split between lamellae in a ring around the nucleus.
Transverse (peripheral) tears: Occur in the outermost fibers near their bony attachment.
By location (where around the disc) Radiopaedia:
Central (midline).
Paracentral (just off midline).
Posterolateral, foraminal, extraforaminal (side regions affecting nerve roots).
