Spine J:多节段胸椎黄韧带骨化症应尽早减压治疗

胸椎黄韧带骨化(Ossification of the ligamentum flavum, OLF)是发生在黄韧带的一种异位骨化。当骨化的韧带增厚、增大到一定程度时,压迫胸段脊髓,引起神经功能障碍,即为胸椎管狭窄症。OLF是胸椎管狭窄症的常见原因之一,可以发生在胸椎的任一节段,也可连续2节段以上受累或呈跳跃性分布,其中上胸椎与下胸椎最为多见。 【原文阅读】 越来越多的研究证据表明,黄韧带骨化是

越来越多的研究证据表明,黄韧带骨化是导致亚洲人群出现胸椎脊髓病或神经根病的重要原因之一。目前手术减压解除压迫是治疗本病的唯一有效方法,通过椎管的后方减压,切除增厚的椎板、关节突及骨化肥厚的黄韧带,使脊髓受压的因素解除。目前用于治疗OLF的后路减压手术有多种,包括椎板切除术、椎管成形术、 椎间孔切开术、开门式椎板切除术等。

研究发现,单节段或双节段OLF患者的减压手术治疗效果要明显优于多节段(≥3)OFL患者。此外,由于较单节段或双节段OLF更为少见,多节段OLF相关的临床研究证据较缺乏,其临床特征、手术结果及影响因素均有待进一步明确。近期的The Spine Journal杂志发表了一项由上海长征医院高瑞、杨立利等人完成的回顾性研究。

通过该研究,作者进一步探讨了多节段OLF的临床特征,评价了椎板切除术治疗多节段OLF的安全性与有效性,分析了影响患者手术疗效的因素。在该研究中,作者将长征医院1996年1月至2010年6月期间连续收治的75例行减压手术的多节段OLF患者作为研究对象。

75例OLF患者中,男性患者43例,女性患者32例,年龄范围为36至78岁,平均为57.4岁。所有患者均接受后路椎板切除术,以解除对脊髓的压迫。分别在术前与术后随访时,采用改良日本骨科学会(JOA)脊髓病评分量表对患者的神经功能进行评价。

同时,并通过术前术后的评分结果计算出JOA评分恢复率,公式为(术后JOA评分-术前JOA评分)/(11-术前JOA评分)×100。作者通过研究患者的病历和手术相关资料,分析了多节段OLF的临床特征。通过多元回归分析以确定手术疗效与各种因素之间的相关性。

该研究结果显示,患者的累及节段平均为4.6个,其中73.3%的患者存在连续多节段OLF。最常累及的胸椎节段分别为T10/T11 (15.4%)、T9/T10 (13.3%)、以及T11/T12(12.5%)。75例患者中有41例(54.7%)患者伴有其它脊柱疾病。

所有患者的术前JOA评分为5.8±1.7,其中37.3% 的患者为轻度脊髓病,53.3% 的患者为中度脊髓病,9.3%的患者为重度脊髓病。行后路椎板切除术后,患者的JOA评分较术前显著增加,平均为8.2±2.1。多元回归分析结果显示,患者术前症状的持续时间和术前的JOA评分是影响手术疗效的重要因素。

该研究结果表明,椎板切除术联合部分内固定是治疗多节段胸椎黄韧带骨化的一种安全有效的方法。同时由于患者术前症状持续的时间和术前JOA评分是影响手术疗效的重要因素,因此建议多节段胸椎黄韧带骨化患者一经确诊,应尽早行减压手术治疗。
