        ObjectiveTo investigate the clinical effect of bone graft impaction on posterior intervertebral fusion for lumbar spondylolisthesis.MethodsFrom January 2001 to July 2008,36 patients with lumbar spondylolisthesis were treated by bone graft impaction on posterior lumbar intervertebral fusion(PLIF)with internal fixation.The clinical outcome were evaluated according to Japanese Orthopaedic Association(JOA)scores and Oswestry disability index(ODl).X-ray evaluation at pre-operation,post-operation and the last follow-up period were performed with slip angle,slip rate and intervertebral disc height,and then the post-operative reduction rate and fusion rate were calculated.ResultsAll patients were followed up from 13 to 25 months(average 16.8 months).Postoperative JOA scores,ODI,slip angle,slip rate and intervertebral height index improved compared with preoperative data(P < 0.05),while there were no statistical differences of the above parameters as well as JOA improvement rate and slip reduction rate between postoperative and the last follow-up period(P > 0.05).Bony fusions were observed in all cases without neurological complications or internal fixation loosening and breakage.ConclusionBone graft impaction on posterior intervertebral fusion was one of the effective methods for the treatment of lumbar spondylolisthesis.15 refs,2 figs,2 tabs.
