等离子刀联合髓核化学溶解术（胶原酶）治疗腰椎间盘突出症的近期疗效观察

目的探讨应用等离子刀融切术联合髓核化学溶解术（胶原酶）治疗腰椎间盘突出症（lumbar intervertebral disc protrusion,LIDP）的效果。方法2002年1月～2007年1月,对80例LIDP应用等离子刀手术系统对突出的腰椎间盘进行汽化消融成形,然后注入溶于5ml无菌生理盐水的国产胶原酶1200U溶解椎间盘内的髓核组织。结果80例术后2周、4周、6个月获得随访,按改良的MacNab疗效评估标准,优62例,良10例,可6例,差2例。优良率90%（72/80）。无严重并发症发生。结论应用等离子刀联合髓核胶原酶溶解手术是一种行之有效的微创治疗方法,但其适应证应严格掌握。

Radio-frequency Disc Nucleoplasty and Chemonucleolysls with Collagenasc for Lumbar Disc Herniation

Objective To investigate the efficacy of radio-frequency disc nucleoplasty and chemonucleolysis with collagenase for the treatment of lumbar disc herniation.Methods Eighty patients with lumbar disc herniation were treated by nucleoplasty combined with chemonucleolysis using collagenase（1200 U） in our hospital from January 2002 to January 2007.Results The patients were re-examined in 2 weeks,4 weeks and 6 months after the operation.According to the modified MacNab criteria,62 patients achieved excellent outcomes,10 were good,6 were fair,and 2 were poor.The rate of excellent and good outcomes were 90%（72/80）.No serious complications occurred in this series.Conclusion Radio-frequency disc nucleoplasty and chemonucleolysis with collagenase are minimally invasive and effective for lumbar disc hernia.
