摘　　要：目的:探讨实时三维导航辅助微创经椎间孔腰椎椎体间融合术(minimally invasive transforaminal lumbar interbody fusion,MIS-TLIF)与传统开放TLIF术治疗腰椎退行性疾病后腰骶部矢状位参数的动态变化。方法:回顾性分析2017年9月至2019年9月行单节段手术治疗的腰椎退行性疾病患者61例。其中导航辅助MIS-TLIF组患者31例,传统开放TLIF组患者30例。收集两组患者的基本信息、手术时间、术中出血量,测量患者术前及术后3个月随访时矢状位影像学参数:腰椎前凸角(lumbar lordosis,LL),节段前凸角(segmental lordosis,SL),骨盆入射角(pelvic incidence,PI),骨盆倾斜角(pelvic tilt,PT),骶骨倾斜角(sacral slope,SS),融合节段的椎间隙前高(anterior disc height,ADH)和椎间隙后高(posterior disc height,PDH),计算椎间隙平均高度(disc height,DH),骨盆-腰椎匹配值(pelvic incidence to lumbar lordosis mismatch,PI-LL)。结果:导航辅助MIS-TLIF组手术时间、术中出血量显著少于传统开放TLIF组(P<0.05)。导航辅助MIS-TLIF组患者术后3个月的LL、SL、PI-LL、DH与术前比较有明显改善(P<0.05),而PI、PT、SS与术前相比较,差异无统计学意义(P>0.05)。传统开放TLIF组患者术后3个月的LL、PI-LL、DH与术前比较有明显改善(P<0.05),而PI、PT、SS、SL与术前比较,差异无统计学意义(P>0.05)。LL的改变值与SL的改变值(r=0.433,P<0.05)有显著相关性;SL的改变值与ADH的改变值(r=0.621,P<0.05),PDH的改变值(r=0.527,P<0.05)有显著相关性。结论:实时导航辅助MIS-TLIF与开放TLIF治疗腰椎退行性疾病患者在短期内均可恢复DH,改善LL及PI-LL,使术后腰骶部矢状面序列的排列更为协调,但只有导航辅助MIS-TLIF能显著提高SL。与开放TLIF相比,实时导航辅助MIS-TLIF治疗腰椎退行性疾病患者具有手术时间短、术中出血少等优点。Objective:To explore the dynamic changes of lumbosacral sagittal parameters after real-time three-dimensional navigation assisted minimally invasive transforaminal lumbar interbody fusion(MIS-TLIF)and traditional open TLIF for treatment of lumbar degenerative disease.Methods:The clinical data of 61 patients with lumbar degenerative disease underwent single-segment surgery from September 2017 to September 2019 were retrospectively analyzed.Among them,31 cases underwent MIS-TLIF with 3D navigation techniques(MIS-TLIF group)and another 30 cases underwent conventional open TLIF(traditional open TLIF group).The basic information,operative time and intraoperative blood loss were collected.The sagittal radiologic parameters were measured before surgery and 3 months after surgery,including lumbar lordosis(LL),segmental lordosis(SL),pelvic incidence(PI),pelvic tilt(PT),sacral slope(SS),anterior disc height(ADH),posterior disc height(PDH).And the average disc height(DH)and pelvic incidence to lumbar lordosis mismatch(PI-LL)were calculated.Results:Operative time and intraoperative blood loss in MIS-TLIF group were significantly less than in traditional open TLIF group(P<0.05).In MIS-TLIF group,LL,SL,PI-LL,and DH were significantly improved at 3 months after surgery(P<0.05),while PI,PT,and SS were not statistically different from those before surgery(P>0.05).LL,PI-LL,and DH of patients in the traditional open TLIF group were significantly improved at 3 months after surgery(P<0.05),while the PI,PT,SS,and SL were not statistically different from those before surgery(P>0.05).LL change showed a significant correlation with SL change(r=0.433,P<0.001).Change in SL closely correlated to change in ADH(r=0.621,P<0.05)and PDH(r=0.527,P<0.05).Conclusion:Real-time navigation-assisted MIS-TLIF and traditional open TLIF can recover DH in a short term for lumbar degenerative diseases,improve LL and PI-LL,and make the arrangement of the sagittal plane of the lumbosacral region more coordinated after surgery.But only the navigation assisted
