Entire Spinal Canal Stenosis in Lumbar canal Stenosis

Abstract

We studied the characteristic findings of lumbar canal stenosis associated with the entire spinal canal stenosis. They are as follows; 1) They have generally severe symptoms. 2) They tend to have various neurological deficits. 3) They show many intervertebral lesions in myelogram. 4) They tend to have urinary-fecal disturbance. 5) They sometimes complicate with cervical or thoracic lesions. 6) Their recovery are poor. In this report, we made the radiological standard for the entire spinal canal stenosis; C₅≤14mm, T₁₁≤13mm, and L₄≤17mm in sagittal diameter. Filmfocus distance was 1.5m at C₅, 1m at T₁₁ and L₄. According to the standard, 51% of lumbar canal stenosis were regarded as the entire spinal canal stenosis.
