PLIF联合PLF与单纯PLIF治疗腰椎退行性疾病的临床比较研究

目的: 比较后路椎体间融合(PLIF)联合后外侧融合(PLF)与单纯PLIF治疗腰椎退行性疾病的疗效.方法: 78例接受脊柱融合治疗的腰椎退行性疾病患者,随机分为PLIF联合PLF组(n=40)和单纯PLIF组(n=38),随访24周,在不同的时间点观察所有病例的ODI指数、腰椎前凸角、节段前凸角、椎间隙高度、腰椎滑脱率及融合率,并记录术中出血量、术后48 h内引流量、术后切口疼痛程度及并发症发生情况,根据随访结果对两组进行比较.结果: 78例均获得随访,PLIF联合PLF组与单纯PLIF组之间临床症状改善、腰椎前凸角、节段前凸角及椎间隙高度、滑脱率改善、两组间融合率和出血量无明显统计学差异(P＞0.05),PLIF联合PLF组术后48 h内引流量较单纯PLIF组多(P＜0.05),术后3 d切口疼痛程度大于单纯PLIF组(P＜0.05).结论: 联用或不联用PLF对椎弓根内固定下PLIF治疗腰椎退行性疾病的短期临床疗效、融合率无明显影响,联用PLF可增加手术创伤.

Clinical comparison of posterior lumbar interbody fusion with or without posterolateral lumbar fusion in treatment of degenerative lumbar diseases

Objective To study the clinical outcomes of posterior lumbar interbody fusion(PLIF) with and without posterolateral lumbar fusion(PLF) in treatment of degenerative lumbar disease.Methods A total of 78 patients who underwent lumbar fusion surgery because of degenerative lumbar disease from March 2007 to February 2008 were studied.All cases were blindly randomized into group PLIF+PLF and group PLIF.The follow-up period was 24 weeks.Oswestry disability indix,lumbar lordosis angle,segmental lordosis angle,disc ...
