Isthmic Spondylolisthesis is Associated with Less Revisions for Adjacent Segment Disease After Lumbar Spine Fusion Than Degenerative Spinal Conditions : A 10-Year Follow-Up Study
Objective: We aim to compare the rate of revisions for adjacent segment disease (ASD) after lumbar spine fusion (LSF) surgery between patients with isthmic spondylolisthesis (IS) and degenerative lumbar spine disorders (DLSD). Summary of Background Data: ASD is a major reason for late reoperations after LSF surgery. Several risk factors are linked to the progression of ASD, but the understanding of the underlying mechanisms is imperfect. If IS infrequently becomes complicated with ASD, it would emphasize the role of the ongoing degenerative process in spine in the development of ASD. Methods: 365 consecutive patients that underwent elective LSF surgery were followed up for an average of 9.7…
Postoperative Sagittal Balance Has Only a Limited Role in the Development of Adjacent Segment Disease After Lumbar Spine Fusion for Degenerative Lumbar Spine Disorders : A Subanalysis of the 10-year Follow-up Study
Study Design. Retrospective additional analysis of a prospective follow-up study. Objectives. We aimed to find out whether poor postoperative sagittal alignment increases revisions for adjacent segment disease (ASD) after lumbar spine fusion (LSF) performed for degenerative lumbar spine disease. Summary of Background Data. Revisions for ASD accumulate over time after LSF for degenerative lumbar spine disease. The etiology of ASD is considered multifactorial. Yet, the role of postoperative sagittal balance in this process remains controversial. Materials and Methods. A total of 215 consecutive patients who had undergone an elective LSF surgery for spinal stenosis with (80%) or without (20%) …
