title: The spinal canal in symptomatic lumbar disc lesions.
abstract: The oblique sagittal diameter of the lumbar spinal canal was measured by diagnostic ultrasound in seventy-three patients with symptomatic disc lesions, and compared with measurements from 200 asymptomatic subjects. Results suggest that the available space in the spinal canal is highly significant in the symptomatology of disc lesions, and in the patient's response to treatment.
