Congenital stenosis of the cervical spinal canal is the narrowing of the spinal canal in the neck (Fig. 1). This condition, which exists at birth but is not hereditary, puts the affected person at increased risk of injuring the spinal cord.
The spinal canal lies within the spine and encases the spinal cord. The vertebral body (back bone) forms the front and the lamina (bony covering) forms the back of this canal. The spinal cord travels from the brain through the canal to the lower back, giving feeling and movement to the entire body.
