摘要(Abstract):
[目的]评估急性踝关节骨折X线测量与MRI诊断下胫腓联合损伤的相关性,为临床诊治下胫腓联合损伤提供建议和方法。[方法]56例急性踝关节骨折均行Denis-weber分型和Lauge-Hansen分型,骨折分型结合X线测量评定下胫腓联合损伤,MRI作为参照标准来评估下胫腓联合的完整性,以此来统计分析X线检查发现下胫腓损伤相对于MRI的敏感性和特异性,并对X线测量值与韧带损伤进行Spearman等级相关分析。[结果]Denis-weber分型中结合测量值,发现下胫腓联合损伤的敏感性为49%,特异性为100%,Lauge-Hansen分型的敏感性为93%,特异性为94%,下胫腓间隙和下胫腓重叠阴影不与下胫腓联合损伤成完全对应关系,增宽的距骨内踝间隙不与三角韧带损伤成对应关系。[结论]根据Lauge-Hansen骨折分型判断下胫腓联合损伤与MRI表现更接近;与X线检查相比,MRI能更准确地评估下胫腓联合损伤的严重程度。
