Abstract: 【Abstract】 Objective To investigate the curative effect of posterior lumbar interbody fusion autogenous morselized bone graft impaction for senile lumbar degeneration Methods A retrospective study was performed for 54 cases of senile lumbar degeneration and all cases were undergone posterior lumbar interbody fusion autogenous morselized bone graft impaction .The efficacy evaluation through follow-up. Results 54 cases were followed up of 6 to 30 months, an average of l4 months. All cases with lumbar interbody fusion had good bone graft fusion, normal disc space and no loss of spondylolisthesis reduction. During the follow-up, the total success rate was 89.72%. Conclusion It is a good method for posterior lumbar interbody fusion autogenous morselized bone graft impaction to cure senile lumbar degeneration.
