两种经椎间孔腰椎间融合术治疗腰椎滑脱症的疗效比较OACSTPCD

Objective To compare the efficacy of unilateral biportal endoscopic transforaminal lumbar interbody fusion(UBE-TLIF)and minimally invasive transforaminal lumbar interbody fusion(MIS-TLIF)for treatment of lumbar spondylolisthesis.Methods Sixty-two patients with lumbar spondylolistheses were divided into two groups according to the different surgical methods,including UBE-TLIF group(30 cases)and Mis TLIF group(32 cases).The surgical indicators,pain VAS,ODI,SF-36 scores,intervertebral height(IH),Cobb angle and lumbar lordosis(LL),interbody fusion and complications were compared between the two groups.Results All patients were followed up,the time was 12～18 months in UBE-TLIF group,and 12～19 months in MIS-TLIF group.Compared with MIS-TLIF group,UBE-TLIF group had a longer operation time,but less intraoperative blood loss and shorter hospital stay(P<0.05).IH,Cobb angles and LL:at the last follow-up,two group were improved than the preoperation(P<0.05),there were no statistical differences between the two groups(P>0.05).Pain VAS of low back pain and leg pain,ODI and SF-36 scores:the two groups were improved than before operation(P<0.05),of which the pain VAS of the low back and legs and SF-36 scores had no statistical differences between the two groups(P>0.05),while ODI in UBE-TLIF group was lower than that in MIS-TLIF group(P<0.05).There was no statistical difference in bone grafting fusion rate be-tween the two groups at 6 months after surgery(P>0.05),all patients achieved bone fusion at the last follow-up.No complications such as dural tear,spinal epidural hematoma,nerve root injury and infection occurred in the two groups after operation.Conclusions Both MIS-TLIF and UBE-TLIF can achieve good clinical efficacy for treatment of lum-bar spondylolisthesis,but UBE-TLIF has the advantages of less intraoperative bleeding and shorter hospital stay
