What It Is

Spinal stenosis is a narrowing of the space inside your spine (the spinal canal), which can put pressure on the spinal cord and the nerves that travel through it. It most often occurs in the lower back and the neck. Some people have no symptoms, but the condition can cause pain, muscle weakness, numbness and problems with the bowel or bladder (NIAMS, 2023a).

Spinal stenosis is most often caused by normal wear-and-tear changes in the spine that come with growing older. In severe cases, surgery might be needed to create more space for the nerves or spinal cord.

Spinal stenosis happens most often in adults over 60 and affects men and women equally. A small number of people are born with a narrow spinal canal (congenital spinal stenosis), which is more common in men (AAOS, n.d.). It can also follow an injury to the spine.

Possible Causes of Spinal Stenosis?

  1. Inherited – some people are born with a small spinal canal or have a curvature of the spine (scoliosis) that puts pressure on nerves.
  2. Osteoarthritis wears away the cartilage surface of joints, and is often accompanied by overgrowth of bone (bone spurs), which may narrow the spinal canal.
  3. Rheumatoid arthritis – inflammation and enlargement of the soft tissues of the joints.
  4. Tumours of the spine – abnormal growths that may affect the spinal canal.
  5. Injury (trauma), such as from an accident.
  6. Paget's disease of bone – a long-term disorder that typically results in enlarged and deformed bones.

Spinal Stenosis Anatomy

The spine is made up of a number of small bones, called vertebrae, stacked one on top of the other. Ligaments, nerves, muscles and intervertebral discs are other parts of the spine.

The vertebrae connect to create a canal that shields and protects the spinal cord. The spine has three main sections that create natural curves in your back: the neck (cervical), the chest area (thoracic) and the lower back (lumbar). Below the five lumbar vertebrae is the sacrum, made of vertebrae fused together, which joins the spine to the pelvis.

Spinal nerves travel through the spinal canal to carry messages between the brain and the muscles. Nerve roots branch out from the spinal cord through openings in the vertebrae.
