4,5,7 As it is impossible to see the fracture lines in the absolute lateral radiograph of the hip,7 we used a schematic diagram showing a hip in this radiographic view. Thus as we observe the oblique radiographs Ixazomib purchase of the hip, we sequentially transfer to the drawing the fractures in the walls, in the columns and of the columns. (Figure 4) As a result it is possible to see the lines and the “format” of the fracture, which allows it to be more easily understood. Figure 4 Drawings representing acetabular fractures. (A) Anterior column, (B) Posterior column, (C) T-shaped. We would be transforming information from the radiographs into information from the drawing, creating the lateral view and thus managing to perceive the location of the lines of the fracture, being able to classify it.

As a presentation of a clinical example we have the images of an acetabular fracture in the anteroposterior, alar and obturator views. In the anteroposterior image (Figure 5) we did not manage to clearly define the fracture lines. When studying the oblique images we managed to visualize that there is interruption of the iliopectineal lines and of the ischiopubic ramus in the foraminal view and we transported these fracture lines to the diagram. In the alar view we observed the fracture line on the iliopubic line and transported it to the diagram. At the end we have the absolute lateral view of the hip drawn and can now clearly observe the type of fracture. In the example it is a T-fracture. (Figure 6) Figure 5 Anteroposterior pelvis.

The radiographic films were photographed with a Sony Cyber-shot DSC-W320 camera, always by the same person, and diagrammed in a slide presentation, with the identifications concealed.

AV-951 We selected eight posterior wall, four anterior wall, five posterior column, four anterior column, three transverse, five column and posterior wall, five anterior column and hemitransverse, five transverse and posterior wall, six two-column, and five T-fracture cases. (Table 2). All the cases were analyzed and classified by each individual from the two groups simultaneously, in five 30-minute sessions, and were reevaluated three weeks afterwards in a new order of presentation.
