3-DIMENSIONAL ANALYSIS OF CALCANEAL FRACTURES

Thirty calcaneal fractures in 22 patients were evaluated by conventional radiographs, two dimensional computed tomography scans (2D CT) and three dimensional computed tomography reformations (3D CT). A special protocol for the reproducible procurement of high quality 3D CT scans was developed and is presented for the first time. Computer-generated three dimensional plastic models of fractured calcanei and videotaped presentations of fractured calcanei were made in selected cases. This study is the first to reproducibly demonstrate the usefulness of 3D CT scans in visualizing a calcaneal fracture. This information highlights the rotational displacement of major fracture fragments (multiplanar malrotation) and can facilitate the preparation of an appropriate surgical approach and reconstruction.
