Lumbar spinal stenosis.
Lumbar spinal stenosis may be congenital or acquired. A classic clinical presentation is described as neurogenic claudication. Physical signs of sensory loss, weakness, and attenuation of reflexes often are mild and limited in distribution. Neuroimaging of the lumbosacral spine with MRI and electrodiagnostic (electromyographic [EMG]) tests are the most informative diagnostic modalities. Conservative management often is successful, but surgical decompression may be indicated in refractory cases.
