Diagnostic value of CT in pelvic fracture by trauma

In order to determine the diagnostic value of CT in pelvic trauma, esp. acetabular fracture, we analysed 32cases of pelvic trauma with conventional radiographic and CT findings. The results were as follows: 1. There were26 males and 6 female and peak age span was 4th decade. 2. In 32 cases of acetabular fracture, single columnfracture were diagnosed in 20 cases and two column fracture in 12 cases by CT. Among signle column fractures,anterior column fractures were 8 cases. Complelx fracture was most common type in two column fractures. 3. In 32cases of acetabular fractures diagnosed by CT, 18 cases could be detected by palin X-ray. 4. Intraarticular bonyfragments were detected on CT in 11 cases and on plain x-ray in 2 cases. 5. Combined soft tissue injuries were 13cases of pelvic hematoma, 1 case of retroperitoneal hematoma and 2 cases of hemarthrosis. 6. CT was useful inacetabular injury to delineate the extent and type of fracture, localize intrarticular bony fragments,characterize joint dislocation and detect the combined soft tissue injury.
