【摘要】 目的比较前路和后路腰椎椎体间融合内固定术治疗下腰椎不稳的疗效。方法将48例下腰椎不稳患者按入路方式不同分为两组,其中前路融合内固定(ALIF组)20例,后路融合内固定(PLIF组)28例。比较两组的术中出血量、手术时间、术后椎间高度、术后并发症,评价临床疗效。结果术中出血量、手术时间两组间比较差异均有统计学意义(P<0.01);两组术后椎间高度、JOA评分与术前比较差异均有统计学意义(P<0.05),两组间比较差异无统计学意义(P>0.05);并发症发生率两组间比较差异无统计学意义(P>0.05)。结论 ALIF和PLIF内固定均是治疗下腰椎不稳的有效术式,但应严格掌握适应证和禁忌证,根据病变类型加以选择。更多还原

【Abstract】 Objective To compare clinical effect of lumbar instability treated with anterior lumbar interbody fusion(ALIF) and posterior lumbar interbody fusion(PLIF) combined with internal fixation.Methods 48 lumbar instability patients were divided into two groups: 20 cases were treated with ALIF combined with internal fixation and 28 cases were treated with PLIF combined with internal fixation.Blood loss,operative time,the height of the intervertebral space,clinical effect evaluation and postoperative complications were compared.Results Blood loss,operative time between groups differences were statistically significant different(P < 0.01);preoperative and postoperative intervertebral height,JOA score differences were statistically significant different(P < 0.05),but the two differences between groups was not statistically significant(P > 0.05);complication rate of the two groups showed no significant difference different(P > 0.05).Conclusions Both ALIF and PLIF combined with internal fixation are good surgery method for lumbar instability.The technique used should conform to the type of lesion with strict control of indications and contraindications.更多还原
