Spinal Stenosis

 

Definition
Spinal stenosis is a narrowing of the spinal canal. The spinal canal is located within the backbone. It is a small space that holds the nerve roots and spinal cord. If this space becomes smaller, it can squeeze the nerves and the spinal cord. This causes pain and other symptoms. Stenosis can occur anywhere along the spinal cord. It is most common in the low back (lumbar) region.

Some people are born with narrowed canals. Most often stenosis is a result of aging. Conditions that can cause spinal stenosis include:

  • Rheumatoid arthritis
  • Spinal tumors
  • Trauma
  • Paget's disease of the bone
  • Previous surgery

Risks
Factors that increase your chance of spinal stenosis include:

  • Being born with a narrow spinal canal
  • Age: 50 or older
  • Previous injury or surgery of the spine
