Abstract Objective To evaluate the effect of posterior lumbar interbody fusion combined with unilateral and bilateral pedicle screw fixation in treatment of single-level lumbar degenerative spondylolisthesis.Methods Fifty-two patients with single-level lumbar degenerative spondylolisthesis were treated with posterior lumbar interbody fusion combined with unilateral or bilateral pedicle screw fixation.According to the different fixation,they were divided into the unilateral group (25 cases) and the bilateral group (27 cases).The preoperative and postoperative visual analogue scale (VAS) and Oswestry disability index (ODI) scores,operation time,intraoperative blood loss,hospitalization costs and fusion rate were recorded and compared between the two groups.Results All patients completed the operation successfully and were followed up.At the last follow-up,VAS and ODI scores were significantly lower than those before surgery,P<0.01.The operation time,intraoperative blood loss and operation cost of patients in the bilateral group significantly increased,compared with those in the unilateral group,P<0.01.At the last follow-up,solid fusion was achieved in both groups.Conclusion The posterior lumbar interbody fusion combined with unilateral pedicle screw and bilateral pedicle screw fixation in treatment of single-level lumbar degenerative spondylolisthesis have comparable clinical outcomes,and unilateral pedicle screw has more advantages on operation time,intraoperative blood loss and hospitalization costs.
