Overview
Spinal stenosis results from new bone and soft tissue growth on the
vertebrae, which reduces the space in the spinal canal. When the nerve roots are pinched, a painful burning, tingling and/or numbing sensation is felt from
the lower back down to the legs and sometimes all the way to the feet.
Healthy Spine
The spinal canal has a rounded triangular shape that holds the nerve roots without pinching. Nerve roots leave the spinal canal through openings called nerve root canals which are also free of obstruction.
Affected Spine
New bone growth within the spinal canal causes compression of the nerve roots, which leads to the pain of spinal stenosis. |
