Most digital models of the equine distal limb that are available in the community are static and/or subject specific; hence, they have limited applications in veterinary research. In this paper, we present an articulatable model of the entire equine distal limb based on statistical shape modeling. The model describes the inter-subject variability in bone geometry while maintaining proper jointspace distances to support model articulation toward different poses. Shape variation modes are explained in terms of common biometrics in order to ease model interpretation from a veterinary point of view. The model is publicly available through a graphical user interface (https://github.com/jvhoutte/equisim) in order to facilitate future digitalization in veterinary research, such as computer-aided designs, three-dimensional printing of bone implants, bone fracture risk assessment through finite element methods, and data registration and segmentation problems for clinical practices.
目前社区中可用的大多数马远端肢体的数字模型都是静态的和/或特定于个体的；因此，它们在兽医研究中的应用有限。在本文中，我们基于统计形状建模提出了一个完整马远端肢体的可关节活动模型。该模型描述了骨骼几何形状的个体间变异性，同时保持适当的关节间隙距离，以支持模型向不同姿势的关节活动。形状变化模式根据常见的生物特征进行解释，以便从兽医的角度简化模型解释。该模型通过图形用户界面（https://github.com/jvhoutte/equisim）公开提供，以促进兽医研究中的未来数字化，如计算机辅助设计、骨植入物的三维打印、通过有限元方法进行骨折风险评估以及临床实践中的数据配准和分割问题。
