摘要：

目的:评价后路选择性胸腰弯或腰弯融合治疗青少年特发性脊柱侧凸(adolescent idiopathic scoliosis,AIS)的临床效果。方法:回顾性分析45例行后路选择性胸腰弯(20例)或腰弯(25例)融合的Lenke 5C型AIS病例,男4例,女41例,平均年龄14.9±2.1岁(12～20岁)。所有病例均行后路椎弓根螺钉内固定矫形融合,平均随访36±20个月(24～105个月)。术前、术后及末次随访时均摄站立位全脊柱正侧位X线片,对躯干偏移、融合节段邻近椎间盘开角、远端融合椎的倾斜、冠状面和矢状面Cobb角进行测量分析。测量数据使用SPSS 17.0统计学软件进行分析。结果:术前胸腰弯或腰弯Cobb角平均47.3°±7.2°,术后矫正至6.4°±4.6°,矫正率(84.8±11.6)%,末次随访时为9.1°±5.4°,矫形丢失2.7°±4.6°。胸弯术前25.7°±7.4°,凸侧Bending像Cobb角7.6°±5.8°,柔韧性(72.7±23.0)%,术后矫正至13.2°±6.7°,自动矫正率(48.5±29.4)%,末次随访14.2°±7.6°,矫形丢失1°±6°。躯干偏移:术前21.3±11.5mm,术后19.5±13.3mm,末次随访10.9±8.9mm。术后近端与远端融合椎邻近椎间盘开角较术后明显减小,且在随访过程中无明显加重。远端融合椎倾斜术后及末次随访时均显著改善。末次随访时,交界性后凸1例,躯干失衡3例,胸弯失代偿并行融合延长手术1例。所有病例末次随访时均未见假关节形成。结论:后路选择性胸腰弯或腰弯融合对Lenke 5C型特发性脊柱侧凸可获得满意矫形效果,胸弯可获得良好的自动矫正,有效缩短了融合节段。
