Abstract

The objectives of this study were to (a). create 3D reconstructions of two carpal bones from single CT data sets and animate these bones with experimental in vitro motion data collected during dynamic loading of the wrist joint, (b). develop a technique to calculate the minimum interbone distance between the two carpal bones, and (c). validate the interbone distance calculation process. This method utilized commercial software to create the animations and an in-house program to interface with three-dimensional CAD software to calculate the minimum distance between the irregular geometries of the bones. This interbone minimum distance provides quantitative information regarding the motion of the bones studied and may help to understand and quantify the effects of ligamentous injury.

摘要

本研究的目的是

(a). 从单一CT数据集中创建两块腕骨的三维重建模型，并利用在腕关节动态加载过程中收集的体外实验运动数据使这些骨骼动起来；(b). 开发一种技术来计算两块腕骨之间的最小骨间距离；(c). 验证骨间距离的计算过程。该方法利用商业软件创建动画，并使用一个内部程序与三维CAD软件接口，以计算骨骼不规则几何形状之间的最小距离。这种骨间最小距离提供了有关所研究骨骼运动的定量信息，可能有助于理解和量化韧带损伤的影响。
