In translation from Greek, stenosis means narrowing. Chronic compression of nerve structures resulting from narrowing of the spinal canal is a dangerous, slowly progressive disease. And while earlier treatments for complex forms of stenosis included discectomy or decompression, today, minimally invasive options are available.
Lumbar decompression surgery is used to treat compressed nerves in the lower (lumbar) spine and it is often recommended when all forms of treatment have been attempted without success.
