Operative Outcome of Instrumented Posterior Spinal Fusion with Free Bone Graft in Symptomatic Isthmic Lumbosacral Spondylolisthesis in Adults

ABSTRACT

Background: ISpondylolisthesis is defined as anterior or posterior slipping of one segment of the spine on the next lower segment. The mainstay of surgical treatment for adult patients with low-grade acquired spondylolytic spondylolisthesis is fusion, with or without decompression. Objectives: To study the safety, efficacy and functional outcome of surgical management of lumbo-sacral spondylolisthesis with pedicle screw fixation, and free bone grafting, and its associated complications. Methods: 10 adult patients with lumbosacral spondylolisthesis treated by instrumented posterior spinal fusion with free iliac chips bone graft and their followup with functional and radiological parameters. Results: Following operation 5 patients(50%) having excellent results & 2 patients(20%) have good results. Conclusion:Instrumented posterior fusion with free graft is a good option for symptomatic lumbosacral spondylolisthesis and also has added advantages of correction of olisthesis, three column stabilization and early mobilization.
