摘　　要：目的分析踝关节正侧位及足正斜位X线检查在诊断第5跖骨基底骨折中的价值,优化检查流程。方法选取96例第5跖骨基底骨折患者,同时进行踝关节正侧位及足正斜位X线检查,比较4种投照体位下第5跖骨基底骨折及Mehlhorn分型的显示情况。结果96例患者中,86例在踝关节正位显示骨折,90例在踝关节侧位显示骨折,65例在足正位显示骨折,83例在足斜位显示骨折。踝关节正侧位显示骨折率高于足正斜位(91.7%vs.77.1%,χ^(2)=15.486,P<0.01)。踝关节正位和踝关节侧位显示骨折率差异无统计学意义(89.6%vs.90.0%,χ^(2)=1.091,P>0.05)。踝关节正侧位对Ⅰ型和Ⅲ型骨折显示率优于足正斜位(Ⅰ型:92.9%vs.71.4%,χ^(2)=6.574;Ⅲ型:93.9%vs.77.3%,χ^(2)=7.439,P<0.05),两者对Ⅱ型骨折显示率比较差异无统计学意义(89.3%vs.79.8%,χ^(2)=2.912,P>0.05)。踝正位及侧位显示Ⅰ型、Ⅱ型骨折差异无统计学意义(Ⅰ型:100.0%vs.85.7%,χ^(2)=3.231;Ⅱ型:85.7%vs.92.9%,χ^(2)=1.120,P>0.05),显示Ⅲ型骨折差异有统计学意义(87.9%vs.100.0%,χ^(2)=4.258,P<0.05)。结论踝关节正侧位较足正斜位更能清晰显示第5跖骨基底骨折,建议对足部扭伤后踝关节及第5跖骨基底处肿胀疼痛的患者首选拍摄踝关节正侧位片。Objective To analysis the value of X-ray examination in anteroposterior and lateral view of ankle and anteroposterior and oblique view of foot in the diagnosis of the fracture of the fifth metatarsal base,and optimize the inspection process.Methods A total of 96 patients with the fracture of the fifth metatarsal base were included in this study,and the X-ray examination was performed in the anteroposterior and lateral view of ankle and anteroposterior and oblique view of foot at the same time.The display of the fracture of the fifth metatarsal base in all 4 projections and the Mehlhorn classifications were analyzed.Results In all 96 patients,86 patients showed the fracture in the anteroposterior view of ankle joint,90 patients showed the fracture in the lateral view of ankle joint,65 patients in the anteroposterior view of foot,and 83 patients showed the fracture in the oblique view of foot.The fracture rates of ankle joint in anteroposterior and lateral view were higher than those in the anteroposterior and oblique view of foot(91.7%vs.77.1%,χ^(2)=15.486,P<0.01).There were no significant differences in fracture rates between the anteroposterior and lateral view of ankle joint(89.6%vs.90.0%,χ^(2)=1.091,P>0.05).For Mehlhorn classifications,the anteroposterior and lateral view of ankle joint showed better than those of the anteroposterior and oblique view of foot in typeⅠandⅢ(typeⅠ:92.9%vs.71.4%,χ^(2)=6.574;typeⅢ:93.9%vs.77.3%,χ^(2)=7.439,P<0.05).There was no significant difference in typeⅡbetween the both(89.3%vs.79.8%,χ^(2)=2.912,P>0.05).There was no significant difference in typeⅠand typeⅡbetween the anteroposterior and lateral view of ankle(typeⅠ:100.0%vs.85.7%,χ^(2)=3.231,typeⅡ:85.7%vs.92.9%,χ^(2)=2.912,P>0.05),but there was significant difference in typeⅢ(87.9%vs.100.0%,χ^(2)=4.258,P<0.05).Conclusion The anteroposterior and lateral view of ankle joint can show the fracture of the fifth metatarsal base clearly,and it is suggested anteroposterior and lateral view of ankle should be t
