不同术式治疗复发性腰椎间盘突出症的疗效分析

Analysis on the Efficacy of Different Surgical Procedure for Recurrent Protrusion of Lumbar Intervertebral Disc

目的探讨不同术式治疗复发性腰椎间盘突出症的疗效。方法选择2011年4月至2013年4月我院收治的复发性腰椎间盘突出症患者64例为研究对象,将患者按手术方式的不同分为PLIF组和改良PLIF组各32例。观察比较两组患者治疗前后JOA评分以及手术相关指标。结果两组术后JOA评分均较术前显著升高(P<0.05),而术前、术后组间比较,JOA评分均不存在统计学意义(P>0.05)。改良PLIF组手术时间显著短于PLIF组,术中出血量显著低于PLIF组,差异均具有统计学意义(P<0.05);但两组椎间高度变化相比无显著差异(P>0.05)。结论 PLIF与改良PLIF治疗效果相当,而改良PLIF其手术时间短、术中出血量少,对患者的创伤更小,是一种更加良好的治疗方式。

Objective To study the efficacy of different surgical procedure for recurrent protrusion of lumbar intervertebral disc.Methods 64 patients with recurrent protrusion of lumbar intervertebral disc treated in our hospital from April 2011 to April 2013 were selected and divided into PLIF group and advanced PLIF group according to different surgery method, with 32 cases in each group. The JOA score and operation-related indicators before and after the surgery in two groups were compared. Results The JOA score of two groups were significantly increased after operation（P〈0.05）, but the JOA score between two group before and after operation had no statistical difference（P〉0.05）. The operative duration of advanced PLIF group was shorter than that of PLIF group, the intraoperative blood loss was lower than that of PLIF group, the difference was statistical（P〈0.05）; but the changes of intervertebral height in two groups had no statistical difference（P〉0.05）. Conclusions PLIF and advanced PLIF have equal effect in the treatment of recurrent protrusion of lumbar intervertebral disc, but advanced PLIF has shorter operation time, less intraoperative blood loss and smaller trauma, which is a better treatment method.
