Computed tomography in traumatology with special regard to the advances of three-dimensional display.

There is a variety of methods to aid in the diagnosis of fractures requiring operative treatment. A computer program that produces pseudo-three-dimensional (3D) images from sets of axial computed tomograms is used for examining fractures in areas of complex skeletal anatomy. The resulting reconstructions, representing the surface in a form similar to that of anatomic preparations, can facilitate the process of diagnosis. They are also valuable for planning operations. The 3D information can be used to define the size, shape, and location of the various fracture types. We have used the technique in more than 500 patients with injuries to the skull, spine, acetabulum, sternoclavicular joint, shoulder, knee, and calcaneus and are able to demonstrate the benefit of special investigation protocols.
