Possible use of 3D-printing technology in orthopedic surgery ranges from preoperative planning to dedicated counselling with patients by the use of individual 3D models, intraoperative surgery tools or implants and various other applications. This article describes a technique for the creation of intraoperative tools with which the process from computed tomography (CT) images to 3D-printed tools in trauma surgery can safely be administered. For segmentation of CT images a range of different software options is available. The standard triangulation file created in this way (file ending: .stl) must subsequently be post-processed. By the use of the digital casts from bone and fractures in computer-aided design (CAD) programs implants and patient individual tools are created, which can range from ortheses to protheses to intraoperative saw guides.
3D打印技术在骨科手术中的可能用途涵盖从术前规划到通过使用个性化3D模型、术中手术工具或植入物以及各种其他应用为患者提供专门咨询。本文描述了一种创建术中工具的技术，利用该技术可以安全地完成从计算机断层扫描（CT）图像到创伤手术中3D打印工具的过程。对于CT图像的分割，有一系列不同的软件选项可供选择。以这种方式创建的标准三角测量文件（文件后缀：.stl）随后必须进行后处理。通过在计算机辅助设计（CAD）程序中使用骨骼和骨折的数字模型，创建植入物和患者个性化工具，其范围可以从矫形器到假体再到术中锯导板。
