BMJ:这类“不稳定”Weber B 型踝骨折,石膏固定疗效不劣于手术

2026-01-19 吾乃喵大人 MedSci原创 发表于上海

对于初始X线对位良好、仅因外旋应力测试阳性而被判定为“不稳定”的单纯Weber B型外踝骨折,采用为期六周的石膏固定是一种功能结局不劣于手术、且并发症风险显著更低的治疗选择。

深度解析医学证据,DeepEvidence为你支撑决策 踝关节骨折是成人最常见的骨折之一,其中约60%为Weber B型(外踝)骨折。长期以来,临床决策的核心在于判断踝关节“窝”(踝穴)是否稳定。对于X线片上显示踝穴对位良好(同心)的骨折,传统观念认为若通过应力测试发现“隐匿性不稳定”,则通常需要手术内固定以预防对位丢失和继发性关节炎。然而,手术本身伴随感染、神经损伤、内固定物相关问题等风险。是否存在这样一组患者,他们虽被诊断为“不稳定”,但实际上通过单纯的石膏固定即可获得与手术相当的良好结局?芬兰研究者开展的SUPER-FIN随机对照试验,为这一关键问题提供了极具说服力的答案。 这项,发表于《英国医学杂志》(BMJ)的研究,采用了随机、实用、非劣效性设计,旨在头对头比较石膏固定与切开复位内固定钢板手术,治疗一类特定的踝关节骨折。研究对象的入选标准极为严谨:均为骨骼成熟的单侧Weber B型外踝骨折患者;初始X线片必须显示踝穴同心(内侧间隙<4毫米且不大于上侧间隙1毫米以上);但随后在荧光透视下进行标准化的外旋应力测试时,必须出现不稳定迹象(内侧间隙≥5毫米)。在2013年至20
