Brief Summary

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Methods: This retrospective study was performed in patients who received L5/S1 PLIF with pedicle screw instrumentation for lumbar spinal stenosis with or without isthmic spondylolisthesis. They were divided into the total laminectomy group, which had destruction of the PLC of the adjacent segment, or partial laminectomy group, which did not. Vertebral slip, osteophytes, disk height, and range of motion were examined by plain radiography, and thickness of the ligamentum flavum (LF) and anteroposterior diameters of the lumbar vertebral body and spinal canal were assessed by magnetic resonance imaging (MRI). Disc degeneration and spinal stenosis on MRI scans were categorized. The incidence of ASD and clinical outcome were compared between the groups.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
group 1
patients in this group destructed the posterior ligamentous complex of the adjacent segment
total laminectomy
Total laminectomy removes the posterior ligamentous complex (PLC) at the fusion and superior levels.
group 2
patients in this group did not destruct the of the posterior ligamentous complex of the adjacent segment
No interventions assigned to this group
