What Is Lumbar Spinal Stenosis?

What is lumbar spinal stenosis?

The term “stenosis” comes from the Greek word meaning “choking” and is often the result of degenerative conditions such as osteoarthritis and/or degenerative spondylolisthesis.

Lumbar spinal stenosis is a medical condition in which the spinal canal narrows and compresses the nerves at the level of the lumbar vertebrae. This is usually due to the common occurrence of spinal degeneration that occurs with aging. It can also sometimes be caused by spinal disc herniation, osteoporosis, a tumor, or trauma.

Other facts about lumbar spinal stenosis include:

  • Patients can develop low back pain as well as pain, weakness, and numbness or decreased sensation in the legs.
  • Surgery is recommended when other nonsurgical treatments have failed and for patients with increasing weakness of the legs or loss of bowel or bladder function.


  • Surgery includes a lumbar decompression with or without a lumbar fusion.
  • Surgery is most reliable for the relief of leg symptoms and less reliable for the relief of back pain.

You’d better consult with your doctor if you are concerned about lumbar spinal stenosis.
