Eur Spine J:退变性腰椎滑脱症尚无统一手术方法

2014-06-12 伊文 丁香园

退变性腰椎滑脱症最早由Junghanns提出,后由Newman进一步描述。腰椎滑脱是由于先天性发育不良、创伤、劳损等原因造成相邻椎体骨性连接异常而发生的,上位椎体与下位椎体部分或全部滑移,导致椎管狭窄伴或不伴脊柱不稳。有学者认为,椎间盘退变可能是导致腰椎滑脱症发生的主要因素,其次,髂腰韧带和椎间小关节也是腰椎滑脱症发生的危险因素。【原文下载】 腰椎滑脱症的发病机理是复杂的,截止到目前,腰椎滑脱症

腰椎滑脱症的发病机理是复杂的,截止到目前,腰椎滑脱症的治疗方案仍存在争议。于是,瑞士学者Steiger等对1990年1月1日至2011年11月16日期间发表的研究进行了归纳总结,该研究结果已在近期的Eur Spine杂志上发表。

按既定的检索方案,搜索MEDLINE, EMBASE,Cinahl和 Cochrane 图书馆,并按照既定的纳入与排除标准,最终纳入相关研究21项(3项随机对照试验,6项前瞻性队列研究,8项回顾性队列研究,3项综述,1项指南)。并且,作者对纳入的研究进行了质量评价,其中,临床研究采用Downs and Black方法,综述研究采用AMSTAR方法。

该研究结果显示,在随机队列研究中(304名患者),66%的患者四年内采取手术治疗。而在保守治疗的患者中,54%的患者四年内采用了手术治疗。并且,手术治疗患者术后疼痛评分为15.3(SF-36),体力功能评分为18.9(SF-36),Oswestry残疾指数为-14.3。于是,作者认为,伴椎管狭窄的腰椎滑脱症,手术治疗较保守治疗,患者疼痛显著缓解,且功能显著改善。

本研究的缺点如下:1.纳入研究的质量较低,可能伴随高的偏倚风险,2.由于纳入研究存在异质性,并且研究结果的多变形,本文不能进行定量分析,3. 本研究仅仅纳入了全文为英文和德文的相关研究,并且未搜索灰色文献和未发表的文献。

该研究结果表明,退行性腰椎滑脱适合何种手术治疗方案的指征仍不明确。手术治疗的并发症发生率为5%-10%,医疗并发症发生率为3%,年龄可能与并发症发生率升高相关。
