Distal Extraforaminal Cervical Annular Tear

A distal extraforaminal cervical annular tear is a crack or fissure in the outer ring (annulus fibrosus) of an intervertebral disc in the neck. It occurs beyond (distal to) the neural foramen, where the nerve root exits the spinal canal. This tear allows the inner gel (nucleus pulposus) to press on nearby tissues, potentially causing pain and nerve irritation NCBIRadiopaedia.

Anatomy

Structure and Location

The annulus fibrosus is the tough, fibrocartilaginous ring that surrounds the soft nucleus pulposus within each cervical intervertebral disc (C1–C7). In cervical extraforaminal tears, the defect lies lateral to the neural foramen, outside the spinal canal NCBIRadiopaedia.

Origin and Insertion

The annulus fibrosus originates from the ring apophysis of the vertebral body above and inserts onto the ring apophysis of the vertebral body below. Its concentric lamellae run obliquely between these endplates, alternating orientation to resist torsion NCBINCBI.

Blood Supply

Only the outer third of the annulus fibrosus has a limited blood supply, primarily from small branches of the vertebral and ascending cervical arteries. This sparse vascularity slows healing when tears occur Physiopedia.

Nerve Supply

Sensory nerve fibers from the sinuvertebral (recurrent meningeal) nerves innervate the outer one-third of the annulus fibrosus. In-growth of these fibers into a tear can generate pain signals NCBIPhysiopedia.

Functions

1. Shock Absorption: The annulus fibrosus cushions vertical loads by evenly distributing pressure across the disc surface during movements such as walking and lifting Spine-healthKenhub.
2. Load Distribution: Concentric lamellae direct forces from the vertebral bodies into the nucleus pulposus, protecting the spine from focal stress Spine-healthKenhub.
3. Restraining Movement: It limits excessive rotation and shear between vertebrae, preventing abnormal motions that could harm the spinal cord or roots Spine-healthKenhub.
4. Maintaining Disc Height: By containing the nucleus, it preserves disc height and the space for nerve roots in the foramina Spine-healthKenhub.
5. Protecting the Nucleus Pulposus: It prevents gel extrusion under normal pressures, maintaining internal disc integrity Spine-healthKenhub.
6. Spinal Stability: Along with ligaments and muscles, it contributes to overall cervical spine stability during activities Physiopedia.

Types

1. Radial Tears: Fissures that extend from the inner nucleus toward the outer annulus, potentially leading to herniation if they reach the outer fibers NCBI.
2. Concentric Tears: Circular splits between lamellar layers, often linked to repetitive stress rather than sudden injury NCBI.
3. Peripheral (Transverse) Tears: Tears at the outer rim of the annulus, usually from traumatic injury or bone spurs; these are most likely to cause symptoms if they disrupt the nerve supply NCBI.

Causes

1. Degenerative Disc Disease: Wear-and-tear breakdown of disc components over time weakens the annulus, making tears more likely Bonati Spine InstituteVerywell Health.

2. Natural Aging: Age-related dehydration and loss of disc elasticity create microfissures that can progress to full tears Verywell Health.
