Spinal stenosis is narrowing of the spinal column that causes pressure on the spinal cord, or narrowing of the openings (called neural foramina) where spinal nerves leave the spinal column.

Spinal stenosis usually occurs as a person ages.
- The spinal disks become drier and start to bulge.
- The bones and ligaments of the spine thicken or grow larger. This is caused by arthritis or long-term swelling.
Spinal stenosis may also be caused by:
- Arthritis of the spine, usually in middle-aged or older people
- Bone diseases, such as Paget disease
- Defect or growth in the spine that was present from birth
- Herniated or slipped disk, which often happened in the past
- Injury that causes pressure on the nerve roots or the spinal cord
- Tumors in the spine
- Fracture or injury of a spinal bone
