What is spinal stenosis?

Spinal stenosis is a narrowing of the space within the spine, which can put pressure on the spinal cord and nerves that travel through it.

Lumbar spinal stenosis is not a single condition. It is a category of conditions, each with a distinct symptom pattern, a different mechanical driver, and a different treatment target. This guide shows you exactly how to identify your type and match treatment specifically to it.
