Spinal stenosis

Definition:

Spinal stenosis is a narrowing of the lumbar (back) or cervical (neck) spinal canal, which causes compression of the nerve roots.


Causes, incidence, and risk factors:

Spinal stenosis mainly affects middle-aged or elderly people. It may be caused by osteoarthritis or Paget's disease or by an injury that causes pressure on the nerve roots and/or the spinal cord itself.
