Abstract

The value of the computed tomography(CT) in the diagnosis of the pelvic bone (especially acetabulum) is being explored. Simple radiographic projections, including specially designed views, although very helpful, often can not provide sufficient information to give a true sense of the fractures.CT,converoly displays the anatomy in a axial plane, thereby providing the missing pieces of information and greatly fascilitating accurate classification of these fractures. In addition, the extent of the soft tissue damage and joint involvement is precisely demonstrated. 10 patients with acetabular fracture, were adimitted to Koryo General Hospital and were taken the CT, were reviewed. Comparing simple radiographic findings with those of the CT, we have made the following conclusions: 1. CT was shown to be useful in the evaluation of the acetabular fractures. 2. CT could detect the pattern of acetabular fracture including degree of fracture fragment, displacement and loose body fragment, and stability of the hip joint. 3. Follow-up of the CT was helful in confirming the extent of bony union of the acetabular fracture. 4. CT was more sensitive than simple radiography in detecting fractures involving the anterior column of the acetabulum.
