摘　　要：目的：比较单侧和双侧后路椎体间融合术（ PLIF）治疗腰椎间盘突出伴腰椎不稳的临床疗效。方法手术治疗51例腰椎间盘突出伴腰椎不稳患者，其中行单侧PLIF治疗26例（单侧组），行双侧PLIF治疗25例（双侧组），比较两组的手术时间、术后并发症、临床疗效满意率和植骨融合率。结果手术时间：双侧组（168±20） min，单侧组（94±18） min；术中出血量：双侧组（750±41） ml，单侧组（450±40） ml；术后输血：双侧组7例，单侧组均未输血；以上各项两组比较差异均有统计学意义（ P＜0.05）。术中硬膜囊撕裂：双侧组1例，单侧组无。术后神经根痛加剧：双侧组2例，单侧组1例。患者均获得随访，时间14～30个月。临床疗效优良率：双侧组为84.0％（21／25），单侧组为92.3％（24／26），差异有统计学意义（P＜0.05）。植骨融合率：双侧组为92.0％，单侧组为96.1％，差异无统计学意义（P＞0.05）。结论单侧PLIF治疗腰椎间盘突出伴腰椎不稳创伤小，并发症少，临床疗效满意率优于双侧PLIF。Objective To investigate the clinical outcome of the unilateral posterior lumbar interbody fusion （ PLIF） with bilateral PLIF for lumbar disc herniation with lumbar instability .Methods 51 patients with different type of lumbar disc herniation with lumbar instability were treated by the modified unilateral PLIF （ 26 cases ） and bilateral PLIF（25 cases）.An observational study of operational duration , volume of bleeding, the therapeutic effect, rate of bone graft fusion was conducted .Results The operational duration was （168 ±20） minutes in bilateral PLIF group and （94 ±18） minutes in unilateral PLIF group .The volume of bleeding was （750 ±41） ml in bilateral PLIF group and （450 ±40） ml in unilateral PLIF group.Postoperative blood transfusion： there were 7 cases in bilateral group, but no case needed blood transfusion in the unilateral group;the above difference between the two groups was statisti-cally significant （ P〈0.05 ） .Intraoperative dural tear：1 case was in bilateral group , no case in unilateral group . Nerve root pain increased after surgery：2 cases in bilateral PLIF group and 1 case in unilateral PLIF group .All pa-tients were followed up for 14~30 months.The excellent-good rate of clinical efficacy was 84.0%（21/25）in bilater-al PLIF group and 92.3%（24/26） in unilateral PLIF group,the diffence was statistically significant （P〈0.05）. The rate of bone graft fusion was 92.0%in bilateral PLIF group and 96.1% in unilateral PLIF group （ P〉0.05 ） . Conclusions The unilateral PLIF is safe and efficient techniques to treat lumbar disc herniation with lumbar instabil -ity.There is no significant difference in rate of graft fusion , but unilateral PLIF is superior to bilateral PLIF in the as-pects of clinical efficacy, operational time, trauma, complications and so on.
