  2. Lumbar spinal stenosis - Wikipedia

    en.wikipedia.org/wiki/Lumbar_spinal_stenosis

    The normal lumbar central canal has a midsagittal diameter (front to back) greater than 13 mm, with an area of 1.45 cm 2. Relative stenosis is said to exist when the anterior-posterior canal diameter measures between 10 and 13 mm. Absolute stenosis of the lumbar canal exists anatomically when the anterior-posterior measurement is 10 mm or less.

  3. Spinal stenosis - Wikipedia

    en.wikipedia.org/wiki/Spinal_stenosis

    Such severe spinal stenosis symptoms are virtually absent in lumbar stenosis, however, as the spinal cord terminates at the top end of the adult lumbar spine, with only nerve roots (cauda equina) continuing further down. [15] Cervical spinal stenosis is a condition involving narrowing of the spinal canal at the level of the neck.

  4. Neurogenic claudication - Wikipedia

    en.wikipedia.org/wiki/Neurogenic_claudication

    MRI of the lumbar spine showing spinal stenosis. Neurogenic claudication is one subtype of the clinical syndrome of lumbar spinal stenosis (LSS). [9] No gold standard diagnostic criteria currently exist, but evaluation and diagnosis is generally based on the patient history, physical exam, and medical imaging. [1]

  5. Cauda equina syndrome - Wikipedia

    en.wikipedia.org/wiki/Cauda_equina_syndrome

    CES can be caused by lumbar spinal stenosis, which is when the diameter of the spinal canal narrows. This could be the result of a degenerative process of the spine (such as osteoarthritis) or a developmental defect which is present at birth. In the most severe cases of spondylolisthesis cauda equina syndrome can result. [10]

  6. Claudication - Wikipedia

    en.wikipedia.org/wiki/Claudication

    Spinal or neurogenic claudication is not due to lack of blood supply, but rather it is caused by nerve root compression or stenosis of the spinal canal, [1] usually from a degenerative spine, most often at the "L4-L5" or "L5-S1" level.

  7. Laminotomy - Wikipedia

    en.wikipedia.org/wiki/Laminotomy

    Common symptoms of lumbar stenosis are pain, fatigue, weakness of the muscle and numbness. [2] Stenosis can be caused by old age or an injury to the vertebral column and usually requires a CT scan or MRI to diagnose. [2] Performing a laminotomy can relieve pressure in the spinal canal caused by lumbar stenosis and therefore alleviate symptoms ...
