ROTATIONAL IMAGING OF COMPLEX ACETABULAR FRACTURES

Understanding complex acetabular fractures is difficult and may requir e three-dimensional reformatted computed tomographic (CT) images. This paper evaluates a technique, digital rotational imaging (DRI), that d isplays multiple oblique images of the pelvis and acetabulum. When vie wed statically, DRI provides optimal iliac and obturator oblique proje ctions, often differing in obliquity from the conventional 45-degree o rthogonal views. Dynamic DRI viewing in rapid sequence provides a thre e-dimensional effect that improves perception of acetabular fracture r elationships.
