Abstract

患者的骨几何模型是个体化生物力学建模与分析、手术规划方案制定、手术导板设计、人工关节定制的重要基础。本研究针对股骨提出一种基于统计形状模型的三维快速重建方法，结合患者X线平片数据，实现了个体化患者股骨几何的快速三维建模。模型三维重建的平均误差在1.597~1.842 mm之间，均方根误差在1.453~2.341 mm之间。重建模型的股骨头直径、颈干角、偏置距离和前倾角的平均误差分别为0.597 mm、1.163°、1.389 mm和1.354°。相比传统建模方法，新方法能够在更短时间内较为准确地实现股骨三维快速重建。本文为骨几何三维快速建模提供了新技术，有助于推动针对患者的快速生物力学分析，为骨科植入物的选择与定制植入物假体的快速研发提供新的思路。.
