To evaluate the effectiveness of the method of radiographic interpretation of acetabular fractures, according to the classification of Judet and Letournel, used by a group of residents of Orthopedics at a university hospital.
We selected ten orthopedic residents, who were divided into two groups; one group received training in a methodology for the classification of acetabular fractures, which involves transposing the radiographic images to a graphic two-dimensional representation. We classified fifty cases of acetabular fracture on two separate occasions, and determined the intraobserver and interobserver agreement.
The success rate was 16.2% (10-26%) for the trained group and 22.8% (10-36%) for the untrained group. The mean kappa coefficients for interobserver and intraobserver agreement in the trained group were 0.08 and 0.12, respectively, and for the untrained group, 0.14 and 0.29.
Training in the method of radiographic interpretation of acetabular fractures was not effective for assisting in the classification of acetabular fractures. Level of evidence I, Testing of previously developed diagnostic criteria on consecutive patients (with universally applied reference "gold" standard).
根据Judet和Letournel分类法，评估某大学医院一组骨科住院医师使用的髋臼骨折影像学解读方法的有效性。
我们选取了10名骨科住院医师，将其分为两组；一组接受了髋臼骨折分类方法的培训，该方法涉及将影像学图像转换为二维图形表示。我们在两个不同的时间对50例髋臼骨折病例进行分类，并确定观察者内和观察者间的一致性。
训练组的成功率为16.2%（10 - 26%），未训练组的成功率为22.8%（10 - 36%）。训练组观察者间和观察者内一致性的平均kappa系数分别为0.08和0.12，未训练组分别为0.14和0.29。
髋臼骨折影像学解读方法的培训对辅助髋臼骨折分类无效。证据等级I，对连续患者应用先前制定的诊断标准进行测试（采用普遍适用的参考“金标准”）。
