What Is Spinal Stenosis?
Spinal stenosis is a narrowing of the spinal column, the tubular structure in the back that contains the vertebrae, spinal cord, spinal discs and nerves. Pinched nerves and compression of the spinal cord can result, leading to pain.
The upper and lower spine are more prone to stenosis because they are fairly mobile and therefore suffer more wear and tear. But other diseases involving the spine, such as osteoporosis, degenerative disc disease, arthritis and ankylosing spondylitis, can contribute to spinal stenosis. Among the causes of spinal stenosis are:
Adults age 50 and older comprise the majority of those affected by spinal stenosis, but the condition can occur in younger adults who have had a spinal injury or were born with narrow spinal canals.
