More Information On Spinal Stenosis Symptoms

The spine runs from the neck to the lower back. The spinal bones form a canal to protect the spinal cord. Spinal stenosis occurs when the spinal canal narrows for any of a variety of reasons. This condition is often caused by:

• Bone spurs: Osteoarthritis wear and tear on the spinal bones can lead to the formation of bone spurs growing into the spinal canal. A bone disease known as Paget’s disease, which usually affects adults, can also cause an overgrowth of bone into the spine.
• Injury to the spine: Car crashes and other types of trauma can cause fracture or dislocation of one or more vertebrae. Displaced bone from a spinal fracture can damage the spinal cord. Back surgery can also cause swelling of surrounding tissues that places pressure on the nerves or spinal cord.
• Slipped vertebra/disc (Spondylolisthesis)
• Thickened ligaments: The ligaments that help hold the spinal bones together can thicken and become stiff with aging and bulge into the spinal canal.
• Herniated discs: The discs are the soft cushions that act as shock absorbers between the vertebrae. They tend to dry out with age. Cracks in the exterior of a disc may allow soft inner material to escape and press against the nerves or spinal cord.
