Damage Analysis of a Femur with Total Hip Arthroplasty by FEA with Use of Medical CT Images

摘要

In this study, a finite element model of a femur with a THA stem was developed using CT images of an old female patient. Damage analysis was then performed under different boundary conditions imitating different daily motions that may cause incident bone fracture. A damage theory was introduced to predict tensile and compressive fracture and also compressive yielding of elements. The FEA results exhibited that the Vancouver classification of bone fracture associated with THA can be predicted by CT-FEA with the damage theory.
