3D patient-specific model of the tibia is used to determine the torque needed to initialize the tibial torsion correction.
The finite elements method is used in the biomechanical modeling of tibia. The geometric model of the tibia is obtained from CT images. The tibia is modeled as an anisotropic material with non-homogeneous mechanical properties.
The maximum stress is located in the shaft of tibia diaphysis. With both meshes are obtained similar results of stresses and displacements. For this patient-specific model, the torque must be greater than 30 Nm to initialize the correction of tibial torsion deformity.
使用胫骨的三维个体化患者模型来确定初始化胫骨扭转矫正所需的扭矩。
在胫骨的生物力学建模中采用有限元法。胫骨的几何模型从CT图像中获取。将胫骨建模为具有非均匀力学性能的各向异性材料。
最大应力位于胫骨干的骨干部分。两种网格均获得了相似的应力和位移结果。对于此个体化患者模型，扭矩必须大于30 Nm才能初始化胫骨扭转畸形的矫正。
