目的：在正常人CT薄层影像数据基础上建立跟骨骨折Sanders分型的数字化仿真模型。方法对1名既往无先天性足部病史及外伤史，常规体格检查和影像学检查排除足部异常病变，并同意参加研究项目的健康成年男性志愿者行足跟部64层螺旋CT扫描，采用Mimics 10.01软件进行断层影像(Dicom文件数据)分割处理，重建完整跟骨3D模型；基于Sanders分型原则，采用Mimics 10.01软件的“Simulation”模块对跟骨模型进行骨折造模并输出STL文件保存，将输出的模型通过Cult3D Designer软件的Web插件植入网页进行虚拟现实显示。结果跟骨骨折的Sanders分型数字化仿真模型具有直观、立体和逼真的展示效果，而植入网页后的模型可进行任意方位和不同角度的观察。结论数字化模型的建立有助于增强外科医生对跟骨骨折Sanders分型的准确理解，而基于Web的交互式虚拟现实技术可用于术前方案演练和远程会诊、教学。

Objective To investigate the modeling of digital Sanders classification for calcaneus fractures. Methods The enrolled healthy male volunteers, who had no congenital foot disease and trauma history, were taken regular physical examination and imaging examination to exclude abnormal foot lesions, and agreed to take part in the research content, whose foot data were collected by 64-slice CT scan. And the CT data were exported in the form of dicom for the process of image segmentation via Mimics 10. 01, to build the complete three-dimensional modeling of calcaneus. Based on Sanders classification principles, the simulation module of Mimics software was used to build the calcaneus fractures model, and then saved as STL files. Finally, the selected models, via the Cult3D Designer plug-in, were inserted into webpage for the demonstration of virtual reality. Results The digital models of calcaneus fractures with high visualization were capable of achieving vivid demonstration and observation from different angles and orientations based on web page. Conclusions The digital model of calcaneus fractures enhances the surgeon’s understanding of Sanders classification pre-and intra-operatively. Furthermore, the modeling based on the web page of virtual reality reveals its tremendous potential in the application of preoperative planning, remote surgical education and diagnosis of complicated clinical cases.
