What Causes Spinal Stenosis?

Q:
What causes spinal stenosis?

A:
The most common cause of spinal stenosis is arthritis, a condition caused by the breakdown of cartilage – the cushiony material between your bones — and the growth of bone tissue.

Osteoarthritis can lead to disc changes, a thickening of the ligaments of the spine, and bone spurs. This can put pressure on your spinal cord and spinal nerves.

Other conditions that can cause stenosis include:

  • Herniated discs. If the cushions are cracked, material can seep out and press on your spinal cord or nerves.
  • Injuries. An accident may fracture or inflame part of your spine.
  • Tumors. If cancerous growths touch the spinal cord, you may get stenosis.
  • Paget’s disease. With this condition, your bones grow abnormally large and brittle. The result is a narrowing of the spinal canal and nerve problems.

Some people are born with spinal stenosis or diseases that lead to it. For them, the condition usually starts to cause problems between the ages of 30 and 50.
