摘要:
目的 探讨后Pilon骨折在CT三维重建图像上的形态学表现。方法 将踝关节X线上“双廓征”与“台阶征”作为确诊后Pilon骨折的标准。在CT横断面图像上,分别测量后外侧与后内侧骨块骨折线与双踝连线的夹角(α、β角)、骨折块前后径与胫骨远端前后径比值、骨折块面积与胫骨远端总面积比值; 在CT矢状面图像上,测量骨折块最大高度及骨折线与胫骨解剖轴的夹角(γ、θ角)。结果 36例后Pilon骨折中有28例发生距骨脱位或半脱位,26例骨折线累及内踝。在影像归档和通信系统(PACS)上完成测量,α、β角正负不同,表明骨折线方向不同。后外侧、后内侧骨折块前后径与胫骨远端前后径比值存在统计学差异(P<0.05),分别为29.8%±4.6%和24.3%±5.2%; 后外侧、后内侧骨折块面积与胫骨远端总面积比值无统计学差异(P=0.65); 后外侧、后内侧骨折块最大高度分别为(24.6±6.2)mm与(21.9±8.4)mm,两者有统计学差异(P<0.01); 后内侧骨块骨折线相对于后外侧骨块骨折线更加垂直水平面(P<0.05)。结论 符合X线诊断标准的后Pilon骨折发生距骨脱位概率较高。后Pilon后内侧、后外侧骨折块在骨折线方向、前后径与胫骨远端前后径比值及最大高度方面存在一定差异。
