Letournal and Judet classification of acetabular fracture is widely used. The classification is based on the identification of fracture lines on plain radiographs. Three-dimensional CT scan was claimed to give a better view of the fracture line. Our study showed that intraobserver reproducibility and interobserver reliability were almost the same when classification was done by using plain radiographs and 3D-CT scan. And 3D-CT scan did not increase either the interobserver reliability or the intraobserver reproducibility in classifying the fracture.
髋臼骨折的Letournal和Judet分类法被广泛应用。该分类基于普通X线片上骨折线的识别。三维CT扫描据称能更好地显示骨折线。我们的研究表明，当使用普通X线片和三维CT扫描进行分类时，观察者内再现性和观察者间可靠性几乎相同。并且三维CT扫描在骨折分类中既没有提高观察者间可靠性，也没有提高观察者内再现性。
