New biomechanical criteria for the design of biomimetic hip joint prostheses are presented. Biofidel Finite Element Models have been used both to correctly analyze femur physiological and structural behavior and to assess a new design criterion for the development of innovative hybrid biological hip prostheses. Proper identification of isostatic lines and isorigidity regions for the sintered metal trabecular lattices distribution between the proximal and distal part of the stem has been carried out. The faithful models enables us to properly take into account not-isotropic properties of the femur proximal end, while clarifying the critical mechanical role of the trabecular bone that should be taken into account to design new innovative prosthetic system.
