【摘要】 目的比较MED术与开窗术治疗单节段腰椎间盘突出症的远期疗效。方法对后路单节段腰椎间盘摘除术的39例患者(MED组22例;开窗组17例)进行问卷调查、JOA评分和复查腰椎MRI。在MRI图像上观察并测量手术前后硬膜外压痕的大小、椎间隙的高度、软骨终板的退变以及手术区域信号的改变情况。结果MED组随访(81±8)个月与开窗组随访(73±6)个月的主观评价(满意率、恢复原工作情况、对手术的评价)、客观评价(JOA评分、改善率和优良率)、MRI改变以及并发症比较差异无统计学意义(P>0.05)。结论两种手术方式术后长期随访在患者的主观评价、客观评价、MRI改变以及并发症方面没有明显差别。更多还原

【Abstract】 Objective To investigate the long-term effect of posterior lumbar discectomy and microendoscopic discectomy(MED).Methods Thirty-nine patients who underwent single segment lumbar discectomy were involved,including 22 patients who underwent microendoscopic discectomy and 17 patients who underwent Love method discectomy.The pre-and postoperation conditions were evaluated by using questionnaires and JOA scores.The indentation of the dura,the height of the intervertebral space were measured and the degeneration of endplate and the signal changes of operation areas were observed from MRI.Results The subjective evaluation(the satisfaction rate,working capacity recovery rate and positive judgment of surgery),the objective evaluation(JOA scores,the improvement rate,the excellent rate),changes of postoperative MRI and complications were not significantly different between MED group(mean follow-up period,81±8 months) and Love group(mean follow-up period,73±6 months)(P>0.05).Conclusions The subjective evaluation(the satisfaction rate,working capacity recovery rate and positive judgment of surgery),the objective evaluation(JOA scores,the improvement rate,the excellent rate),changes of postoperative MRI and complications indicate that two operation methods are not significantly different.更多还原
