Decompression without Fusion in Patients with Low-Grade Degenerative Spondylolisthesis and Stenosis: Long-Term Patient-Reported Outcome

This cohort study showed comparable satisfaction and clinical outcomes after decompressive surgery for symptomatic spinal stenosis in patients with and without grade 1 degenerative spondylolisthesis. Decompressive surgery can, therefore, be considered an effective treatment for symptomatic lumbar spinal stenosis, even if it is accompanied by degenerative spondylolisthesis. Therefore, routinely adding instrumented spondylodesis is not deemed necessary.
