摘要(Abstract)：

[目的]回顾性分析经椎弓根双节段闭合型楔形截骨治疗强直性脊柱炎所致重度后凸畸形的临床疗效。[方法]2006年3月～2010年6月,对9例强直性脊柱炎所致重度后凸畸形患者,采用后路经椎弓根双节段(T12、L3)闭合型楔形截骨术。通过术前、术后及随访时矢状面X线片,测量腰椎前凸角、胸椎后凸角,全脊柱最大后凸Cobb角,C7铅垂线与S1后上角距离,术前、术后大体像颌眉角的大小,术前及末次随访患者ODI评分,评价患者畸形矫形效果及生活质量。[结果]9例患者均获随访,随访时间平均3年7个月。术中2例出现硬脊膜破裂,术后4例出现麻痹性肠梗阻,腰椎前凸角、胸椎后凸角、脊柱最大后凸Cobb角术前分别平均为(0.2±4.8)°、(78.4±3.2)°、(86.8±3.2)°。术后分别平均为(33.7±3.0)°、(42.7±3.4)°、(34.44±2.8)°。两处截骨共获得平均(67.9±5.5)°矫形;C7铅线与S1后上角距离术前平均(27.3±4.4)cm,术后平均(3.4±0.7)cm;颌眉角由术前平均(58.8±6.4)°降至术后平均(1.3±3.5)°。患者恢复矢状面平衡,能够平视行走。末次随访ODI评分较术前降低,生活质量明显改善。[结论]随访结果显示经后路椎弓根双节段(T12、L3)闭合型楔形截骨术治疗强直性脊柱炎致严重脊柱后凸畸形是安全的,且可获得良好的矫形效果和生活质量。
