STUDY DESIGN: Retrospective clinical study. OBJECTIVE: To explore the factors influencing the clinical outcomes and motion-preserving stabilization after interspinous soft stabilization (ISS) with a tension band system for grade 1 degenerative spondylolisthesis (DS). SUMMARY OF BACKGROUND DATA: Despite increasing recognition of the benefits of dynamic stabilization systems for treating @entity179 , the factors affecting the clinical and radiological outcomes of these systems have rarely been identified. METHODS: Sixty-five @entity1 (mean age, 60.3 years) who underwent ISS with a tension band system between 2002 and 2004 were analyzed. The mean follow-up period was 72.5 months. The @entity1 were divided according to the postsurgical clinical improvements into the optimal (n = 44) and suboptimal groups (n = 21), and the radiological intergroup differences were analyzed. Multiple linear regression analysis was performed to determine the impact of the radiological factors on the clinical outcomes. RESULTS: Significant intergroup differences were observed on the follow-up clinical examination. Radiologically, @entity1515 ( @entity1515 ) and @entity1347 ( @entity1347 ) were significantly improved only in the optimal group, resulting in significant intergroup differences in @entity1515 (P = 0.023), @entity1347 (P = 0.001), and the L1 tilt (P = 0.002). All these measures were closely associated with @entity86 , which also was the most influential radiological variable for the clinical parameters. CONCLUSION: In the @entity1 with grade 1 DS, the @entity615 relief and functional improvement following ISS were affected by the improvements in the sagittal spinal alignment through the achievement of @entity1347 . ISS can be an alternative treatment to fusion surgery for grade 1 DS in @entity1 who do not require fixation or reduction.
