目的:探讨退变性腰椎管狭窄单纯减压手术对术后临床症状的改善情况及脊柱矢状面形态的影响。材料与方法:分析我院84例退变性腰椎管狭窄患者,均行单纯椎管减压手术治疗,术前、末次随访均行全脊柱站立位X线检查。矢状面参数包括骨盆倾斜角(PT)、胸椎后凸角(TK)、腰椎前凸角(LL)、骶骨倾斜角(SS)、矢状面偏移(SVA)、骨盆入射角(PI)。两组间差异采用配对样本t检验。结果:相比术前,术后LL和TK显著增(P分别为0.024,0.011). SVA和PI-LL显著下降(P分别为0.027,0.004),PT、PI、SS和TLK手术前后无明显变化。术后数字评分法(NRS)分数相比术前均显著降低(P为0.007)。结论:单纯减压手术能有效改善退变性腰椎管狭窄患者的临床症状和恢复脊柱矢状面的形态。
Objective: To evaluate radiographical changes in sagittal spinopelvic alignment and clinical symptoms after decompression surgery for lumbar spinal stenosis. Methods: We retrospectively reviewed 84 patients who underwent lumbar decompression without fusion. Standing whole-spine radiographs at the preoperative stage and at the final follow-up were examined. We analyzed sagittal vertical axis (SVA), lumbar lordosis (LL), pelvic tilt (PT), pelvic incidence (PI), thoracolumbar kyphosis (TLK), and thoracic kyphosis (TK). Results: LL and TK were significantly increased postoperatively. SVA, PI-LL and NRS were significantly decreased. There were no signif-icant differences between the preoperative and postoperative PT, PI, SS, or TLK. Conclusion: Lumbar decompression can lead to a reactive improvement in the lumbar and global sagittal alignment and can improve pre-operative symptoms.
