Article presents a study of mechanical causes of acetabular cup migration. The investigation of possible causes is divided into two groups: (i) micromotions due to cancellous bone overloading which drive the structural changes in the trabecular bone and (ii) osteolysis due to the wear of small particles of polyethylene material introducing formation of osteoagresive granuloma.
Článek se zabývá numerickou analýzou příčin migrace acetabulární komponenty do pánevního dna. Jsou zkoumány mechanické vlivy na přetěžování subchondrální kosti pod acetabulární komponentou a srovnán otěr různých acetabulárních komponent užívaných v ČR.
