摘　　要：目的利用Roussouly分型对固定至骶骨/骨盆的退行性脊柱侧凸(degenerative scoliosis,DS)术后临床疗效和影像学参数特点进行评估,分析其机械性并发症的危险因素,探索Roussouly分型于腰椎长节段固定手术的意义。方法回顾分析2017年12月至2020年12月因DS于我院进行长节段腰骶/骨盆融合手术的45例患者,其中男7例,女38例,年龄55~85岁,平均(70.84±8.52)岁,根据是否符合Roussouly分型分为符合Roussouly分型(RG)组(n=10)和不符合Roussouly分型(NRG)组(n=35);比较两组一般资料,术前及末次随访腰痛视觉模拟评分(visual analogue scale,VAS)、腰椎Oswestry功能障碍指数(Oswestry disability index,ODI)、健康相关生活质量(health related quality of life,HRQoL)以及机械性并发症发生情况,两组脊柱-骨盆影像学相关参数,包括冠状位Cobb’s角、骨盆入射角(pelvic incidence,PI)、骶骨倾斜角(sacral slope,SS)、腰椎前凸角(lumbar lordosis,LL)、腰椎前凸分布指数(lordosis distribution index,LDI)、腰椎前凸椎体数(the number of vertebrae included in the lordosis,NVL)、前凸顶点(the lumbar sagittal apex,LA)、拐点(inflexion point,IP)。根据术后是否发生机械性并发症进行分组,将Roussouly分型相关矢状面参数纳入单因素分析和多因素二元Logestic回归分析,确定机械性并发症的独立危险因素。结果术前RG和NRG两组基线水平一致;术后RG组腰痛VAS评分1.20±0.92小于NRG组的1.97±0.79,差异有统计学意义(P=0.01);术后RG组ODI 13.40±3.69小于NRG组的21.40±7.66,差异有统计学意义(P=0.003);术后RG组SF-36评分75.68±4.81高于NRG的68.25±6.30,差异有统计学意义(P=0.001);RG组LL(48.20±8.48)°大于NRG组的(40.33±5.22)°,差异有统计学意义(P=0.001),RG组SVA 24.55 mm小于NRG组的40.84 mm,差异有统计学意义(P=0.03);两组机械性并发症发生率差异有统计学意义(P=0.04);术后PI(OR=0.797;95%CI=0.657~0.968;P=0.022),LA(OR=0.027;95%CI=0.002~0.438;P=0.011)为术Objective To evaluate the clinical efficacy and imaging parameters of postoperative degenerative scoliosis fixed to the sacrum/pelvis using Roussouly classification,analyze the risk factors for mechanical complications,and explore the significance of Roussouly classification in lumbar long-segment fixation surgery.Methods A retrospective analysis was conducted on 45 patients who underwent long-segment lumbar sacral/pelvic fusion surgery for degenerative scoliosis at Henan Provincial People’s Hospital from December 2017 to December 2020.Among them,7 were males and 38 were females,aged 55-85 years with an average age of(70.84±8.52)years.According to whether they met the Roussouly classification,they were divided into the Roussouly classification(RG)group(n=10)and the non-Roussouly classification(NRG)group(n=35);General data including visual analog scale(VAS),lumbar Oswestry disability index(ODI),health-related quality of life(QOL),and the occurrence of mechanical complications were compared between the two groups.Parameters related to spinal pelvic imaging,such as coronal Cobb’s angle,pelvic incidence angle(PI)sacral slope angle(SS),lumbar lordosis angle(LL),lumbar lordosis distribution index(LDI),the number of vertebrae included in the lordosis(NVL),the lumbar sagittal apex(LA),and inflection point(IP)were compared between the two groups.Based on whether mechanical complications occurred after surgery,the Roussouly classification related sagittal parameters were included in univariate analysis and multivariate binary Logistic regression analysis to determine independent risk factors for mechanical complications.Results The baseline levels of RG and NRG were consistent before surgery;The postoperative VAS score for low back pain in the RG group(1.20±0.92)was lower than that in the NRG group(1.97±0.79),and the differences were statistically significant(P=0.01);The postoperative ODI score in the RG group was(13.40±3.69),while in the NRG group was(21.40±7.66),with statistically significant differences(P=0.003
