Abstract

We retrospectively analyzed 22 patients pelvic CT, in whom the acetabular fracture were suspected in plain film. And compared and analyzed the computed tomogram findings and plain radiographic findings. The results were as follows. CT enables better evaluation of shape, extent, and degree of separation of fragment. CT was helpful in detecting the combined fracture and soft tissue injuries. CT showed intraarticular loose bodies, which were invisible on plain film. In patients with pelvic trauma, no necessary changing position during CT examination. CT was useful demonstrates the remnant of intraarticular osseous fragment and adequacy of reduction after surgery.
