The diagnosis of lumbar stenosis

The diagnosis of stenosis of the lumbar spinal canal is essentially based on clinical and radiographic examination. While clinical signs of involvement of the bone structure are few, neurological ones, however aspecific, may be detected (pluriradicular irritation, neurogenic claudication). Neurological instrumental tests (EMG, evoked potentials, etc.) are not of considerable aid to diagnosis. Radiographic examination, CT and MRI, are essential to prognosis and therapy.
