Nonunions involving fractures of the acetabulum are reportedly rare, with few citings and little discussion in the literature. It is possible that acetabular nonunions go undetected because imaging of the acetabulum is difficult by conventional radiography. We report two cases of fracture nonunion involving the weight-bearing surface of the acetabulum diagnosed with the aid of computed tomography (CT) and a newly developed interactive 2D/3D orthotool (copyright and trademark of the Body CT Imaging Laboratory, Department of Radiology, The Johns Hopkins Medical Institutions) that uniquely processes and reformats routine CT data. The interactive 2D/3D orthotool is a sophisticated computer program that allows dynamic viewing of standard multiplanar reconstructions in the axial, coronal, and sagittal planes as well as multiple oblique projections. The 2D/3D orthotool provides on screen correlation of two-dimensional multiplanar images with three-dimensional reconstructions of the pelvis. The authors found this capability ideally suited for studying fractures with off-axis orientation such as those through the acetabular dome, greatly facilitating the diagnosis of nonunion.
据报道，髋臼骨折不愈合的情况较为罕见，文献中提及较少且讨论不多。髋臼不愈合可能未被发现，因为通过传统放射照相术对髋臼进行成像很困难。我们报告了两例涉及髋臼负重面的骨折不愈合病例，这是借助计算机断层扫描（CT）和一种新开发的交互式二维/三维矫形工具（约翰霍普金斯医疗机构放射科人体CT成像实验室的版权和商标）诊断出来的，该工具能独特地处理和重新格式化常规CT数据。交互式二维/三维矫形工具是一个复杂的计算机程序，它可以动态查看轴向、冠状面和矢状面的标准多平面重建图像以及多个斜位投影图像。二维/三维矫形工具在屏幕上提供二维多平面图像与骨盆三维重建图像的关联。作者发现这种功能非常适合研究具有非轴向方向的骨折，比如通过髋臼顶的骨折，极大地促进了不愈合的诊断。
