Computed tomography of the acetabular fractures

ABSTRACT

In a retrospective study of 21 patients, in whom the acetabular fractures were suspected on initialradiographs, we compared and analysed the CT findings and plain radiographic findings and plain radiographicfindings. The results were as follow 1. In patients with multiple trauma, no further change in position wasrequeired during CT examinations. 2. CT showed intraarticular loose bodies, which were invisible on plainradiographs. 3. CT was useful in detecting the fractures of acetabular rims, medial wall of acetabulum, andfemoral head. 4. CT permitted better evaluation of shape, extent, and degree of separation of fracture fragments.5. CT was helpful indetecting the associated fractures and soft tissue injuries. 6. CT also demonstrated theadequacy of reduction, the position of metallic fixation devices, and the presence or absence of remainingintraarticular osseous fragments after surgery.
