Lumbar canal stenosis

Treatment of neurogenic claudication and lumbar canal stenosis by an FMH neurosurgeon.

What is it?

Lumbar canal stenosis is a narrowing of the spinal canal, through which the nerves supplying the legs travel. It is mainly caused by arthrosis: the nerves of the cauda equina become increasingly compressed over the years.

Which symptoms?

The classic picture is "neurogenic claudication": pain, weakness and tingling in the legs, triggered mainly by walking. Without treatment, walking distance may progressively decrease, sometimes to just a few minutes.

Investigations

The main investigation is a lumbar MRI, which best identifies the level or levels responsible for the symptoms.

Which treatments?

When conservative treatment has failed and walking becomes more and more difficult, it is then reasonable to propose an operation to open the lumbar canal at one or several levels in order to free the nerves.

There are 2 main surgical techniques for lumbar canal stenosis:

  • either a laminectomy, which widely decompresses the dural sac
  • or a selective decompression at one or several levels, which better preserves the bony structures

How do I know if my leg pain comes from my back?

If pain or weakness appears when walking and improves at rest or when leaning forward, lumbar canal stenosis is possible. A lumbar MRI confirms the diagnosis.

Is lumbar stenosis surgery effective?

Surgical decompression aims to give the nerves room again and improve walking distance. Results are discussed case by case during the consultation.
