Lumbar spinal stenosis is difficult to explain and understand, so we’ve created a new video to offer a clear visualization of the condition and its symptoms.

Highlights illustrating spinal stenosis:
Lumbar spinal stenosis affects the nerves housed within the lumbar spine. As you can see above, each lumbar vertebra has a space in the middle, or spinal canal, through which these nerve bundles travel.
Nerve roots extend off of the spinal canal on either side through a space at the back of the vertebrae known as the foramen.
In a healthy spine, both the nerve bundle and the nerve roots are afforded plenty of room within the spinal canal and foramen.
In individuals with lumbar spinal stenosis, degenerative changes such as bone spurs can restrict the space that the nerve bundles have within the spinal canal, putting pressure on the nerves.
Bone spurs can also impinge on the nerve root, narrowing the amount of space available for it.
Common symptoms of lumbar spinal stenosis include weakness or pain that travels from the lower back down the leg.
Now that you have a visual understanding of how lumbar spinal stenosis can develop, take a look at how the condition is diagnosed, treated and managed.
