2-year stress distribution within the femur as a consequence of stem design.

(a) Traditional press fit loading of the femur showing diaphyseal hypertrophy and proximal stress shielding
(b) Proximal femoral loading with a stem design based on the dynamic model of the hip showing bone preservation and no abnormal diaphyseal bone formation
