World Neurosurg:存在神经功能障碍的胸腰椎交界处爆裂性骨折直接减压的必要性

2021-07-23 MedSci原创 MedSci原创

爆裂性骨折的手术治疗是有争议的,有许多不同的手术选择。从后方进入,脊髓减压可以通过间接和直接方法进行,前者依靠韧带牵引。目前还不清楚用韧带牵引的间接减压是否与直接减压一样有效。

爆裂性骨折的手术治疗是有争议的,有许多不同的手术选择。从后方进入,脊髓减压可以通过间接和直接方法进行,前者依靠韧带牵引。目前还不清楚用韧带牵引的间接减压是否与直接减压一样有效。

近日,研究人员对前瞻性的随机对照数据进行回顾性分析,只包括胸腰椎交界处的爆裂性骨折。患者接受直接减压治疗,包括除手术稳定外的广泛后方减压,或间接减压,即仅通过韧带转移进行减压。患者在6个月后接受临床评估和影像学随访。1年后进行额外的临床评估。

 

结果,该研究包括46名患者,其中18名患者为直接减压亚组,28名患者为间接减压亚组。全部队列的平均年龄为35.1±13.1岁(范围为16-60岁)。大多数患者有L1骨折(21/46;46%),骨折形态为AOSpine分类A4型(17/46;37%),并且是美国脊柱损伤协会B级(18/46;39%)。在6个月的随访中,两种治疗方法都导致了类似的椎管直径增加和硬膜囊损伤的减少(P>0.5)。两种治疗方法在1年后的神经系统改善等级相似(P = 0.575)。

综上,在比较直接减压和韧带轴时,临床和影像学结果没有显著差异。在精心选择的病例中,单纯的韧带牵引可能是有效的。
