Short and Medium Term Results of Posterior Segmental Instrumentation and Posterolateral Fusion in Female Patients with Spondylolisthesis: A Clinical Trial

Abstract

Objective: Aim of this study was to short and medium term results of posterior segmental instrumentation and posterolateral fusion in female patients with spondylolisthesis. Materials and methods:Patients with lumbar sponylolisthesis who were performed convetional laminectomy, poliaxial secrew fixation and posterolateral fusion between the 2013 and 2015. The postoperative fusion of the female patients were evaluated through Lumbar 3D Computed Tomography and X-Ray imaging. The patients' low back pain and lower extremities's pain were evaluated with Oswestry disability index and Visual Analogue Score. Retrospective Patients' information were collected via file in May 2016. Result: When the pain scores of the patients who underwent segmental instrumentation were compared in the preoperative, postoperative periods there was the significant decrease in pain scores (p<0.001). Conclusion:The posterolateral fixation and fusion are an efficient treatment method in the medium and short term in female patients with spondylolisthesis. But, a secondary chronic disease such as osteoporosis associated with aging was added to impair bone quality, fusion success rate was seen to be decreased.
