ABSTRACT
[Objective] To investigate the feasibility of posterior interbody parvule-impacted bone graft fusion.[Method] A retrospective study was performed in 31 patients admited to our hospital in 2003~2006(M=14,F=17).The ages were 55 to 80,with an average of 66.2 years.There were 9 cases of spondylolisthesis,6 of degenerative unstability and 16 of developmental stenosis.All patients underwent posterior interbody impact bone graft fusion and pedicle screw fixation.The pre-and post-operative JOA score were used to calculate the improvement rate.The postoperative bending-extending plain films were taken to observe whether the fusion was successful.[Result]All patients were followed up for 12~18 months.Three patient had leg symptoms at postoperation and were released 3 months later.Thirteen patients had fusion at 6 month,16 had union at 12 month,and 2 had union at 18 month.The lumbar lordosis angle and intervertebral height got significant restoration.The spinal fusion rate was 100%.No dura tear leakage of cerebrospinal fluid or wound infection was found.No graft absorption,displacement or collapse occurred.There were 16 cases excellent,12 cases good,and 3 cases fair.JOA score was 24~29(average 27.4?1.9)at postoperation.The improvement rate was 89.4%.[Conclusion] Posterior interbody parvule-impacted bone graft is a feasible fusion method.The method is simple and cheap,with advantages of less injury and high fusion rate.
