导管法胶原酶溶解术治疗腰椎间盘突出症589例

目的：提高胶原酶溶解术治疗腰椎间盘突出症的疗效和安全性。方法：对589例符合纳入排出标准的腰椎间盘突出症患者采用小关节内侧入路，利用穿刺针的导向作用准确置入导管于椎问盘突出部位，注射胶原酶行椎间盘溶解术。结果：按日本骨科学会腰腿痛疗效评分标准，总有效率为96.69％，优良率84.19％。无严重并发症发生。结论：采用导管定向胶原酶溶解术治疗腰椎间盘突出症较传统方法疗效更好，安全性更高。

Curative effects of chemonucleolysis of collagenase with catheterization in lunbar protrusion of intervertebral disc

Objective:To investigate the curative effects and safety of chemonucleolysis with collagenase in protrusion of lumbar intervertebral disc(PLID).Methods:By reviewing 589 patients with PLID who received the treatment of chemonucleolysis with catheterization.These patients were consistent to the standards of conclusion and exclusion.We firstly implanted the lumbar puncture needle by the inner wall of lumbar articular process,then catheterized a catheter,at last,injected the collagenase into the compartment of periphery of lumbar intervertebral disc.Results:According to the JOA score of lumbar leg pain,the total effective rate was 96 69%,and excellent rate was 84 19%.Conclusion:The curative effects and safety of chemonucleolysis with catheterization in PLID is better than that of traditional methods.
