Abstract:
Objective To investigate the clinical effect of the bone graft fusion of the posterior lumbar interbody fusion (PLIF) combined with posterolateral fusion(PLF) in treating lumbar spondylolisthesis .Methods 63 cases of lumbar spondylolisthesis were performed the posterior unilateral or bilateral vertebral plate resection ,nerve root canal decompression ,clearing the slippage space , reduction ,fixation short-segment vertebral pedicle nail-stick system for reduction and fixation ,bone graft fusion with the interverte-bral space Cage and posterior-lateral bone graft fusion ,vertebral pedicle isthmus cracking was performed the clearance and bone graft fusion(PLIF combined with PLF ) .The JOA scores ,lumbar lordosis ,segment lordosis ,intervertebral space height ,slippage rate and complications were recorded before operation ,in postoperative 1 week ,6 ,12 months .Results All cases had no serious complications .The JOA scores were increased to some different degrees from the beginning of postoperative 1 week ,with the reha-bilitation time extension ,the JOA scores were gradually increased ,the improvement rate of the postoperative JOA score averaged 85 .00% .The lumbar lordosis ,segment lordosis ,intervertebral space height and slippage rate after operation were significantly im-proved compared with before operation ,the fusion failure rate was 4 .76% .Conclusion The bone graft fusion of PLIF combined with PLF is one of ideal methods to treat lumbar spondylolisthesis .
