Evaluation of Letournel and Judet classification of acetabular fracture with plain radiographs and three-dimensional...

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.
