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

Expectations (prognosis)
Many people with spinal stenosis are able to carry on active lifestyles for many years with the condition. Some change in activities or work may be needed.
