Abstract:
PURPOSE: This is a retrospective study to analyze the clinical and radiological results of posterolateral fusion with a pedicle screw fixation for lumbar spondylolisthesis. MATERIAL AND METHOD: From January 1994 to June 1997, forty-seven patients with spondylolisthesis were treated by posterolateral fusion with pedicle screw fixation. The clinical results were analyzed according to Kirkaldy-Willis & Kim's criteria and radiological union, reduction of slippage, change of disc space, change of lumbar and segmental angle were assessed by simple X-ray. RESULTS: The good bony union rate of formation and satisfactory clinical results were obtained, but the reduction of slippage, the restoration of disc height and the change of sagittal angle were not sustained. There was a significant relationship between the clinical results and the loss of anterior disc height. CONCLUSIONS: The satisfactory clinical results were seen to be in follow-up observation, and the maintenance of anterior disc height significantly influenced clinical results. We think that the additional operation method is necessary in maintaining the disc height.
