Question: Does degenerative spondylolisthesis affect the outcome of unilateral laminotomy with bilateral decompression in patients with lumbar stenosis?
Answer: Our study thus indicates that preoperative degenerative spondylolisthesis does not worsen the outcome of patients with lumbar stenosis undergoing unilateral laminotomy with bilateral decompression. These results suggest that lumbar fusion is often unnecessary in patients with degenerative spondylolisthesis and lumbar stenosis if the posterior decompression technique is unilateral laminotomy with bilateral decompression.

no
