腰椎间盘镜微创手术治疗单纯性腰椎间盘突出症与开放手术的比较

目的：探讨腰椎间盘镜下椎间盘切除术（MED）治疗单纯性腰椎间盘突出症和传统开放手术相比创伤大小和短期疗效的差别．方法：2003-01／2006—12，临床诊断为单纯性腰椎间盘突出症患者248例，随机分组，分别采用腰椎间盘镜手术和开放手术治疗．对术中、术后反映手术创伤的指标进行监测和观察．术后随访4mo～4a（平均21mo），按照日本骨科协会（JOA）制定的临床随访结果评定标准评价疗效．结果：MED和开放手术相比，手术切k7小、术中出血少、对神经根刺激小，术后全身炎症反应轻、腰部疼痛轻、恢复快、住院时间短．术后短期随访结果显示MED组优良率为92．1％，开放手术组优良率为94．4％．MED和开放手术相比，两者之间短期疗效没有明显差别．结论：MED是一种安全、有效的治疗椎间盘突出的手术方法，和开放手术相比具有术中创伤小、术后恢复快的优点，就短期疗效而言，两者之间没有明显差别．

Comparasion of the tissue invasiveness and the clinical effects of lumbar disc herniation treated by microendoscopic discectomy and traditional open operation

AIM:To compare the tissue invasiveness and the clinical effects of lumbar disc herniation treated by microendoscopic discectomy(MED)and traditional open operation.METHODS:A total of 248 patients with prolapsed lumbar intervertebral disc were treated by microendoscopic discectomy or traditional open operation randomly between January 2003 and December 2006.The METRx system(Medtronic Sofamor Danek,Memphis,TN) was used to perform MED.Parameters which can reflect the tissue invasiveness were monitored and recor...
