24 cases of lumbar spinal stenosis (15 pseudospondylolisthetic, 4 spondylolisthetic and 5 spondylotic stenosis) were treated by laminectomy followed by fusion for the past 5 years (1974 to 1978).
Majority of the cases were middle aged and were engaged in manual labor.
All cases but one had cauda equina claudication.
Myelograms showed a complete block in 14 cases out of 23 cases.
Good results were obtained except one case with cervical spondylotic myelopathy.
