What is cervical annular fissure seen in the protrusion?

Cervical annular fissure refers to a tear or defect in the annulus fibrosus, the tough outer layer of an intervertebral disc in the cervical spine. This condition can occur alongside disc protrusion, where the inner gel-like nucleus pulposus bulges out through the fissure, potentially impinging on nearby nerves. Symptoms may include neck pain, radiculopathy, or other neurological deficits. Treatment often involves conservative measures, such as physical therapy, or in more severe cases, surgical intervention.
