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 32 cases of pelvic trauma with conventional radiographic and computed tomographic findings. The results were as follows : 1. There were 26 males and 6 female and peak age span was 4th decade. 2. In 32 cases of acetabular fractures, single column fracture were diagnosed in 20 cases and two column fracture in 12 cases by CT. Among single column fractures, anterior column fractures were 12 cases and posterior column fractures were 8 cases. Complex fracture was most common type in two column fractures. 3. In 32 cases of acetabular fractures diagnosed by CT, 18 cases could be detected by plain X-ray. 4. Intraarticular bony fragments were detected on CT in 11 cases and on plain X-ray in 2 cases. 5. Combined soft issue injuries were 13 cases of pelvic hematoma, 1 case of retroperitoneal hematoma and 2 cases of hemarthrosis. 6. CT was useful in acetabular injury to delineated the extent and type of fracture, localized intraarticular bony fragments, characterize joint dislocation and detect the combined soft tissue injury
