What is Spinal Stenosis?

Share This Article

Spinal stenosis occurs when an overgrowth of bone or tissue narrows the spaces in an individual’s backbone, resulting in pressure on the spinal cord and/or nerve roots. Most commonly, the disorder is caused by an overgrowth of spinal bones, herniated disks, thickened ligaments, tumors or spinal injuries.

The disorder affects both men and women and most often results from a gradual, degenerative aging process. Thus, the disorder is most common in adults over age 50, though younger people who are born with a narrowing of the spinal canal or who have suffered a spinal cord injury also may be affected by spinal stenosis.
