SHIPLEY, JA. Lumbar spinal stenosis. SA orthop. j. [online]. 2008, vol.7, n.2, pp.42-49. ISSN 2309-8309.
Lumbar spinal stenosis is diagnosed by the clinical picture of radiculopathy and / or spinal claudication caused by narrowing of the spinal canal. Anatomical and radiological features correlate poorly with the clinical features, and are of little prognostic value. The natural history is very benign with fluctuating levels and types of symptoms. Indications for surgery must be individualized, but decompression is effective in the short and medium term. Fusion is only indicated in the case of instability.
