厚度微创椎板间开窗椎管扩大术治疗腰椎管狭窄的疗效

目的:探讨微创椎板间开窗椎管扩大术治疗腰椎管狭窄(LSS)的疗效。方法:对收治的40例LSS患者(研究组)前瞻性实施微创椎板间开窗椎管扩大术治疗,回顾性分析实施常规后路椎板切除减压术治疗的40例LSS患者(对照组)的临床资料,术后随访6~24个月,对比两组患者治疗效果。结果:两组手术时间比较差异无统计学意义(P0.05),但研究组住院时间短于对照组,术中失血量少于对照组(P0.05);两组术后JOA评分有效率、轴性症状发生率、椎间隙高度、腰椎曲度、滑脱程度比较差异无统计学意义(P0.05),但研究组术后伤椎疼痛VAS评分显著低于对照组(P0.05);对照组并发症总发生率高于研究组(P0.05)。结论:微创椎板间开窗椎管扩大术治疗LSS,与常规术式疗效相当,但手术创伤小,术后并发症少。

Minimally Invasive Lamina Windowing Spinal Canal Expanded in the Treatment of Lumbar Spinal Stenosis

Objective:To investigate the effect of invasive lamina windowing spinal canal expanded in the treatment of lumbar spinal stenosis.Methods:40 patients with LSS (the study group) prospectively underwent invasive lamina windowing spinal canal expanded. And the data were retrospectively analyzed of 40 patients with LSS (the control group) between January 2013 and March 2013 who underwent conventional posterior vertebral lamina windowing decompression on both sides. The postoperative follow-up were 6 ~ 24 months. Compare the treatment effect between the two groups.Results:There was no statistical difference in operation time between two groups (P >0.05). However, the hospitalization time of the study group was shorter than that in the control group, and blood loss was less than that in the control group (P<0.05). There were no statistical difference in postoperative JOA score efficient rate, axial symptoms, intervertebral height, degree of cervical curvature, slip degree between two groups (P> 0.05). The injured vertebra pain VAS score after operation in the study group was significantly lower than that in the control group (P<0.05). But the total incidence rate of postoperative complication in the control group was higher than that in the study group (P<0.05).Conclusion:Minimally invasive lamina windowing spinal canal expanded in the treatment of LSS has the same curative effect with conventional surgery, but with less surgical trauma and less postoperative complications.
