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.
通过传统X线片、二维计算机断层扫描（2D CT）和三维计算机断层重建（3D CT）对22例患者的30处跟骨骨折进行了评估。首次制定并展示了用于可重复获取高质量3D CT扫描的特殊方案。在部分病例中制作了计算机生成的跟骨骨折三维塑料模型以及跟骨骨折的录像展示。本研究首次可重复地证明了3D CT扫描在可视化跟骨骨折方面的实用性。这些信息突出了主要骨折块的旋转位移（多平面旋转不良），并有助于制定合适的手术入路和重建方案。
