The planning of the surgical treatment in orthopedics, with the help of three-dimensional (3D) technologies, arouses an increasing scientific interest. Scientific literature describes some semi-automatic reconstructive attempts at fragmented bone fractures, but the matching algorithms presented are likely to improve. The aim of this paper is to develop a new method of aligning fragments of comminutive fractures. We have created a structured integration process and an alignment algorithm integrated in a clinical workflow for personalized surgical treatment of fractures. The provided solution is able to align the surfaces of bone fragments derived from the segmentation process of volumetric tomographic data. Positional uncertainties are eliminated interactively by the user, who selects the corresponding pairs of fracture surfaces. The final matching and the right alignment are performed automatically by the innovative alignment algorithm. The paper solves a challenging problem for the reconstruction of fractured bones, namely the choice of the optimal matching option from the situation in which surface portions of a fracture fragment correspond to multiple high fragments. The method is validated in practice for preoperative planning of a 49-year-old male patient who had a tibial plateau fracture of Schatzker type VI.
借助三维（3D）技术进行骨科手术治疗规划引发了越来越多的科学关注。科学文献描述了一些针对粉碎性骨折的半自动重建尝试，但所呈现的匹配算法仍有改进空间。本文旨在开发一种新的方法来对齐粉碎性骨折的碎片。我们创建了一个结构化的整合过程以及一种集成在临床工作流程中的对齐算法，用于骨折的个性化手术治疗。所提供的解决方案能够对齐从体积断层扫描数据分割过程中获得的骨碎片表面。用户通过交互式操作消除位置不确定性，即选择相应的骨折表面配对。最终的匹配和正确对齐由创新的对齐算法自动执行。本文解决了骨折重建中的一个具有挑战性的问题，即在骨折碎片的表面部分对应多个高位碎片的情况下选择最佳匹配选项。该方法在一名49岁患有Schatzker VI型胫骨平台骨折的男性患者的术前规划中得到了实际验证。
