Instability

he abnormal movement of a vertebra forward (anterolisthesis) or backward (retrolisthesis) can cause compression of the spinal canal

Narrowing of the disc

Wear and tear of the vertebral discs may cause them to dry out and shrink This condition may result in stenosis of the central spinal canal and other openings in the spine

Herniated disc

A herniated (bulging) disc that protrudes posteriorly (toward the spinal cord) or has a broad bulge may push against the spinal cord

Traumatic injury

Trauma to the vertebrae may cause fracture, dislocation, or spondylolisthesis, causing stenosis of the spine

Ligament thickening

The ossification or thickening of the posterior longitudinal ligament and/or the ligamentum flavum may cause stenosis of the central canal
