Spinal stenosis is an abnormal narrowing (stenosis) of the spinal canal (the opening in each vertebra through which the spinal cord passes) that may occur in any of the regions of the spine. This narrowing causes a restriction to the spinal cord, resulting in a neurological deficit. Symptoms include pain, numbness, pins and needles and loss of motor control. The location of the stenosis determines which area of the body is affected.[1]

Cervical spinal stenosis is a bone disease involving the narrowing of the spinal canal at the level of the neck. It is frequently due to chronic degeneration,[2] but may also be congenital. Treatment is frequently surgical.[2]
Symptoms of cervical spinal stenosis include:
