Our aim was to assess the reproducibility and the reliability of the Weber classification system for fractures of the ankle based on anteroposterior and lateral radiographs. Five observers with varying clinical experience reviewed 50 sets of blinded radiographs. The same observers reviewed the same radiographs again after an interval of four weeks. Inter- and intra-observer agreement was assessed based on the proportion of agreement and the values of the kappa coefficient. For inter-observer agreement, the mean kappa value was 0.61 (0.59 to 0.63) and the proportion of agreement was 78% (76% to 79%) and for intra-observer agreement the mean kappa value was 0.74 (0.39 to 0.86) with an 85% (60% to 93%) observed agreement. These results show that the Weber classification of fractures of the ankle based on two radiological views has substantial inter-observer reliability and intra-observer reproducibility.
我们的目的是评估基于前后位和侧位X线片的Weber踝关节骨折分类系统的可重复性和可靠性。五名临床经验各异的观察者对50套盲法X线片进行了评估。间隔四周后，相同的观察者再次评估相同的X线片。基于一致性比例和kappa系数值评估观察者间和观察者内的一致性。对于观察者间一致性，平均kappa值为0.61（0.59至0.63），一致性比例为78%（76%至79%）；对于观察者内一致性，平均kappa值为0.74（0.39至0.86），观察到的一致性为85%（60%至93%）。这些结果表明，基于两种影像学视图的Weber踝关节骨折分类具有较高的观察者间可靠性和观察者内可重复性。
