腰椎间盘镜单节段髓核摘除术远期疗效分析

Long-term effect of posterior lumbar microendoscopic discectomy

[目的]评价腰椎间盘镜（microendoscopic discectomy,MED）单节段髓核摘除术的远期疗效。[方法]回顾性分析2004年1月-2005年1月在本院行MED单节段髓核摘除术的32例患者。术前和术后第1、2、3年行JOA评分、腰椎X线检查,在X线片上测量腰椎前凸角及手术节段椎间隙高度。[结果]术后平均随访36个月（24-46个月）,术前与术后JOA评分、手术节段椎间隙高度差异具有统计学意义（P〈0.05）,腰椎前凸角的变化无统计学意义（P〉0.05）。[结论]腰椎间盘镜单节段髓核摘除术治疗腰椎间盘突出症的远期疗效肯定,对脊柱稳定性的影响小,且并发症少。

[Objective]To investigate the long-term effect of posterior lumbar microendoscopic discectomy（MED）. [Methods]A retrospective study was held.Thirty-two patients who underwent single segment lumbar discectomy between Jan.2004 and Jan.2005 were included.The pre-and post-operative conditions were evaluated by using JOA scores and lumbar X-ray.The height of the intervertebral space and the angle of lumbar lordosis were measured from X-ray.[Results]All the cases were followed up for 24~48 months（averaged 36 months）.The difference of JOA scores and the height of the intervertebral space were significant before and after the operation（P0.05）.The angle of lumbar lordosis had no significant change（P0.05）.[Conclusion]MED is an availabie option for lumbar disc herniation with little effects on spinal stability and fewer complication.
