摘　　要：目的:评价强直性脊柱炎胸腰椎后凸畸形截骨角度的术前预测方法,分析其在脊柱-骨盆矢状序列重建中的临床价值。方法:回顾性分析2015年1月~2022年1月在新疆医科大学第一附属医院行单节段经椎弓根截骨(pedicle subtraction osteotomy,PSO)治疗的22例强直性脊柱炎胸腰椎后凸畸形患者,其中男17例,女5例;年龄29~56岁(44.3±7.4岁);在X线侧位片上测量术前、术后末次随访时的脊柱-骨盆参数,应用躯干整体平衡法(full balance integated index,FBI)、脊柱股骨角法(spine femoral angle,SFA)、肺门-髋轴法(hilus pulmonis-hip axis,HP-HA)、外耳道-髋轴法(center of both acoustic meati-hip axis,CAM-HA)和Surgimap法预测截骨角度,再根据骨盆入射角(pelvic incidence,PI)计算理论脊柱-骨盆参数和理论截骨角度。分别比较术前、术后末次随访时和理论脊柱-骨盆参数的差异以及预测截骨角度、实际截骨角度和理论截骨角度的差异。结果:纳入患者中L1截骨4例、L2截骨10例、L3截骨8例,术后均获得满意的影像学结果和手术疗效,术后末次随访时骨盆倾斜角(pelvic tilt,PT)、骶骨倾斜角(sacral slope,SS)、腰椎前凸角(lumbar lordosis,LL)、胸椎后凸角(thoracic kyphosis,TK)、胸腰段后凸角(thoracolumbar kyphosis,TLK)、整体后凸角(global kyphosis,GK)、矢状面偏移(sagittal vertical axis,SVA)与术前比较差异均有统计学意义(P<0.05)。FBI、SFA、HP-HA、CAM-HA和Surgimap法预测截骨角度分别为50.5°±12.1°、52.0°±11.3°、53.9°±8.1°、51.3°±5.8°和43.2°±9.2°,不同预测方法预测的截骨角度比较差异有统计学意义(F=2.342,P=0.046)。模拟截骨恢复理想脊柱-骨盆矢状序列所需理论截骨角度为51.2°±8.1°,分别与FBI、SFA、HP-HA、CAM-HA预测截骨角度比较均无统计学差异(P>0.05)。术中实际截骨角度41.1°±5.4°,与FBI、SFA、HP-HA、CAM-HA预测截骨角度比较均有统计学差异(P<0.05),与Surgimap法预测截骨角度�Objectives:To evaluate the preoperative prediction methods of osteotomy angle of thoracolumbar kyphosis in ankylosing spondylitis(AS)patients,and to analyze their clinical values in reconstruction of spinopelvic sagittal alignment.Methods:22 AS patients with thoracolumbar kyphosis,who underwent single segment pedicle subtraction osteotomy(PSO)from January 2015 to January 2022 in the First Affiliated Hospital of Xinjiang Medical University,were retrospectively reviewed.There were 17 males and 5 females with a mean age of 44.3±7.4 years(range,29-56 years).Preoperative and postoperative spinopelvic parameters were measured on X-ray lateral radiographs,osteotomy angles were predicted with different methods,full balance integated index(FBI),spine femoral angle(SFA),hilus pulmonis-hip axis(HP-HA),center of both acoustic meati-hip axis(CAM-HA),and Surgimap method.And theoretical spinopelvic parameters and theoretical os-teotomy angle were calculated according to pelvic incidence(PI).The differences between preoperative,final follow-up and theoretical spinopelvic parameters,and between the predictive,actual and theoretical osteotomy angles,were compared.Results:The osteotomy sites of the 22 cases included 4 in L1,10 in L2 and 8 in L3.All the patients achieved ideal imaging and surgical results.The differences in pelvic tilt(PT),sacral slope(SS),lumbar lordosis(LL),thoracic kyphosis(TK),thoracolumbar kyphosis(TLK),global kyphosis(GK),and sagittal vertical axis(SVA)between final follow-up and preoperation were statistically significant(P<0.05).The osteotomy angles predicted with FBI,SFA,HP-HA,CAM-HA,and Surgimap methods were 50.5°±12.1°,52.0°±11.3°,53.9°±8.1°,51.3°±5.8°,and 43.2°±9.2°,respectively,with statistically significant differences(F=2.342,P=0.046).The theoretical osteotomy angle required by simulated osteotomy to restore the ideal spinopelvic sagittal alignment was 51.2°±8.1°,which wasn′t statistically different from the osteotomy angles predicted with FBI,SFA,HP-HA or CAM-HA methods(P>0.05).T
