Abstract
A biomechanical analysis modeling methodology of the acetabulum and acetabular prosthesis using three dimensional finite element analysis is presented. A simplified pelvis model is utilized which will yield accurate bone/component interfacial stresses. The SDRC IDEAS software program was used to perform the associated operations. Model generation of the simplified pelvic model and cup, finite element subdivision; material properties, restraints and load modeling are detailed. The model is comprised of 429 isoparametric elements in the simplified pelvis portion and 633 elements in the cup portion. Materials properties and loads are from the literature. The modeling methodology offers the advantages of determining accurate interfacial stresses without producing complex large scale models and complex calculations. The model can also be used to determine interfacial stresses in any acetabular component with only minor modifications.
