The aim was to assess how the stress shielding can influence the integrity and resistance of bones in presence of a misalignment.
Three finite elements models have been developed: a normal one, and two varus and valgus knee ones.
The obtained results reveal interesting consequences deriving by a wrong disposition of parts which compose the skeletal chain of the leg.
The most dangerous conditions occur in the contact interface between pelvis and hip of the femur, for the valgus knee configuration, and for the varus one, at the contact interface around the knee zone.
本研究旨在评估在存在关节错位的情况下，应力遮挡如何影响骨骼的完整性和抵抗力。
建立了三个有限元模型：一个正常模型，以及两个内翻和外翻膝关节模型。
所得结果揭示了腿部骨骼链组成部分布置错误所产生的有趣后果。
对于外翻膝关节构型，最危险的情况发生在骨盆与股骨髋关节的接触界面；对于内翻膝关节构型，最危险的情况发生在膝关节区域周围的接触界面。
