Spinal stenosis is a narrowing of the spaces in the backbone, or spinal column. This narrowing can put pressure on the spinal cord or nerve roots. The spinal column is formed by the bones of your spine, called vertebrae. The vertebrae have a hollow core. When stacked upon each other, they form a canal that protects and supports the spinal cord. Nerves, called nerve roots, branch off from the spinal cord through spaces between the vertebrae and lead to different parts of your body.
