Spinal Stenosis Overview

The spinal canal is formed by the openings of a series of bones (vertebrae) stacked on top of each other.

  • The upper part of the spinal canal is the cervical spine in the neck, the middle part is the thoracic spine of the midback, and the lower part is the lumbar spine of the lower back.
  • The spinal canal is attached to the head at the top and to the pelvis at the bottom.
  • The spinal cord passes from the brain through the spinal canal and travels down the back. Nerves exit off the spinal cord between vertebrae of the neck and low back that help control the arms and legs respectively.

Spinal stenosis is a condition whereby there is abnormal narrowing in the spinal canal. This narrowing limits the amount of space available for the spinal cord and nerves. As spinal stenosis becomes more severe there is compression or squeezing of the spinal cord and its nerves. Spinal stenosis can occur anywhere in the spinal canal, but it is most common in the cervical and lumbar spine.

Spinal Stenosis Treatment (Nonsurgical)

In the absence of severe or progressive nerve involvement, a doctor may prescribe one or more of the following conservative treatments:

  • Nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin, naproxen, ibuprofen, or indomethacin, to reduce inflammation and relieve pain.
  • Analgesics, such as acetaminophen, to relieve pain.
  • Corticosteroid injections into the outermost of the membranes covering the spinal cord and nerve roots to reduce inflammation and treat acute pain that radiates to the hips or down a leg.
  • Anesthetic injections, known as nerve blocks, near the affected nerve to temporarily relieve pain.
  • Restricted activity (varies depending on extent of nerve involvement).
  • Prescribed exercises and/or physical therapy to maintain motion of the spine, strengthen abdominal and back muscles, and build endurance, all of which help stabilize the spine. Some patients may be encouraged to try slowly progressive aerobic activity such as swimming or using exercise bicycles.
  • A lumbar brace or corset to provide some support and help the patient regain mobility. This approach is sometimes used for patients with weak abdominal muscles or older patients with degeneration at several levels of the spine.
