“…The phenomenon, also known as stress shielding, which occurs at the interface between the bone and the rigid implant, causes a reduction in mechanical stimuli due to strain shielding in parts of the bone-implant bond; it was suspected early on to be a cause of subsequent bone degradation around the implant, resulting in aseptic loosening and migration of the acetabulum. Finite element simulations to localise areas of the artificial acetabular cup that are subject to high strain gave some insights on how to improve the materials [3].…”

“…Dieses Phänomen, am Interface von Knochen und steifem Implantat auch als Stress Shielding bezeichnet, bewirkte durch Lastabschirmung in Teilen des Implantat-Knochen-Verbundes eine Reduktion der mechanischen Reize und wurde bereits frühzeitig als Ursache eines späteren Knochenabbaus um das Implantat mit der Folge der aseptischen Lockerung und Pfannenmigration vermutet. Finite-Elemente-Simulationen zur Lokalisation von hochbeanspruchten Arealen der künstlichen Hüftpfannen gaben Hinweise zur Verbesserung der Materialien [3].…”

“…This approach has the advantage of calculating forces without the necessity of invasive in vivo experiments for different motions. In combination with finite element analysis [9,10] the MBS can help to identify areas of high loadings in the hip joint which can be further used for an optimization of the tribological pairing of prostheses [11-13]. Additionally the MBS can provide knowledge about an optimal positioning of prosthesis components according to an optimal load distribution in the periprosthetic bone.…”
