Clinical and radiological outcome in cases of posterior lumbar interbody fusion for lumbar spondylolisthesis

Abstract

Introduction: Spondylolisthesis is the subluxation of a vertebral body over another in the sagittal plane. It represents a particular and relatively frequent mechanism of intervertebral instability. This pathology can be caused by ligamentous laxity, a defect in the pars interarticularis.Results: There was significant reduction in the postoperative pain and disability at 6 months follow up in back and leg and significant reduction of slippage radiological and significant bony union.Conclusion: Decompression primarily relieves radicular symptoms and neurogenic claudication whereas fusion primarily relieves back pain by elimination of instability. The addition of posterofusion instrumentation (Pedicle screws and cage) enhances the ability to obtain a solidarthrodesis, Posterior Lumbar interbody fusion is a excellent procedure for lumbar spondylolisthesis achieved a significant reduction in low back pain and claudication pain and significant amount of radiological reduction and union.
