We recorded inter- and intra-observer variations in the classification of ankle fractures by the Lauge Hansen and Weber systems. Radiographs of 94 patients were classified independently by four observers. The observer variation was calculated by kappa statistics, which corrects the obtained values for the agreement expected by chance. There was an acceptable level of agreement for the overall classification into both systems. For the staging of supination-adduction and supination-eversion fractures in the Lauge Hansen system the agreement was poor. The results indicate that future classification systems should be subject to reliability analysis before they are accepted.
我们记录了采用Lauge Hansen和Weber系统对踝关节骨折进行分类时观察者间和观察者内的差异。94例患者的X线片由四名观察者独立进行分类。观察者间差异通过kappa统计量计算，该统计量会对偶然预期的一致性所获得的值进行校正。两种系统对总体分类的一致性水平均可接受。在Lauge Hansen系统中，旋后内收型和旋后外旋型骨折的分期一致性较差。结果表明，未来的分类系统在被接受之前应进行可靠性分析。
