Computed tomography (CT) and transverse axial tomography (TAT) were used to study the lumbar spines of 164 patients with persistent or recurrent low back pain and/or radiculopathy. Of those patients with previous spinal fusion and of those with previous disectomy, 43% and 28%, respectively, demonstrated bony stenosis of the lumbar spinal canal. Of the patients who underwent surgery for this narrowed canal, 91% showed clinical improvement.
