摘要(Abstract)：

[目的]探讨重度腰椎峡部裂性滑脱后路椎体间融合手术(PLIF)治疗的临床疗效及影像学表现。[方法]分析2010年1月~2014年1月在本院行手术治疗的共23例重度腰椎峡部裂性滑脱患者。男5例,女18例,平均年龄(51.83±8.82)岁。手术方式均采用腰椎后路减压、椎弓根内固定术和或椎体间融合术。比较术前术后疼痛视觉模拟评分(VAS评分),Oswestry功能障碍指数(ODI指数)和腰椎JOA评分来评估临床疗效,比较手术前后椎体滑脱程度,椎体融合率,手术前后腰椎前凸角(LL),骶骨倾斜角(SS),骨盆倾斜角(PT)和骨盆入射角(PI)评估影像学表现,同时记录所有患者相关并发症发生情况。[结果]VAS评分:术前为(7.54±0.39),末次随访为(2.68±0.32)(P<0.05)。ODI指数:术前(79.22±7.62),末次随访为(21.57±12.09)(P<0.05)。腰椎JOA评分:术前为(8.52±3.17),末次随访为(22.52±3.17)(P<0.05)。术前腰椎滑脱度平均为(3.22±0.60),末次随访为(1.09±0.79)(P<0.05)。LL:术前腰椎前凸角平均(52.34±13.79)°,末次随访为(42.13±17.55)°(P<0.05)。SS:术前骶骨倾斜角平均(36.83±11.31)°,末次随访为(36.85±9.99)°(P<0.05)。PT:术前骨盆倾斜角平均为(23.61±2.13)°,末次随访为(23.68±7.56)°(P<0.05)。PI:术前骨盆入射角平均为(54.32±13.55)°,末次随访为(54.35±17.78)°(P<0.05)。所有患者均获得骨性融合。5例发生一过性下肢神经症状加重;1例发生轻微肺栓塞;1例第一次手术后滑脱纠正不多且未减压,患者症状改善不明显;2例发生螺钉断裂,再次手术。[结论]重度腰椎峡部裂性滑脱PLIF手术治疗疗效满意,手术应在不造成神经损伤的前提下尽可能进行滑脱的复位,但并不强求滑脱完全复位,同时有条件应尽量行椎体间融合。
