1、小趾囊炎足与正常足X线测量及对比分析研究作者:陈思,温建民,孙卫东,韩雪,胡海威,孙永生,梁朝,蒋科卫,程桯【摘要】[目的]通过对小趾囊炎足与正常足X线的测量及对比分析研究,明确小趾囊炎足X线诊断标准。[方法]对131例正常足与117例小趾囊炎足的第4~5跖骨间角(IM4~5),改良4~5跖骨间角(MIM4~5),小趾内翻角(MPA),第5跖骨外翻角(LDA),第5跖骨头宽度(WMH)及突出距离(DPMH)进行X线测量,结合临床对测量结果进行对比分析研究。[结果]小趾囊炎足与正常足平均测量结果分别为:第4~5跖骨间角13.57°±2.99°和8.88°±1.88°,
2、改良4~5跖骨间角12.80°±2.86°和9.28°±2.13°,小趾内翻角18.47°±6.22°和9.96°±5.39°,第5跖骨外翻角6.55°±4.06°和3.36°±2.10°,第5跖骨头宽度13.27mm±1.59mm和12.00mm±1.25mm,第5跖骨头突出距离3.91mm±1.08mm和3.12mm±0.74mm。正常足的范围:第4~5跖骨间角5.19°~12.58°,改良4~5跖骨间角5.09°~13.47°,小趾内翻角1.38°~19.04°,第5跖骨外翻角1.21°~7.59°,第5跖骨头宽度9.55mm~14.45mm,第5跖骨突出距离
3、1.65mm~4.5910mm。小趾囊炎足与正常足X线各测量值的差异均有统计学意义(P<0.01)。小趾囊炎足中第4~5跖骨间角与小趾内翻角之间存在正相关,相关系数r为0.36(P<0.05)。[结论]X线测量是诊断小趾囊炎的重要临床指标。第4~5跖骨间角>9°、小趾内翻角>10°、第5跖骨外翻角>3°并伴有临床症状的患者可诊断为小趾囊炎。【关键词】小趾囊炎;足;X线;测量;诊断Abstract:[Objective]Toidentifythestandardofradiographicdiagnosisandanalysethemea
