N2 - Femur bone stress shielding is known to be a significant factor in aseptic loosening or failure of hip replacements. This paper considers the development of a porous stemmed hip implant for children patient in order to reduce the effects of stress shielding and also maintaining acceptably low levels of stress in other areas of prosthesis. By using finite element modeling, the stresses in the proximal femur using porous stem were calculated and analyzed. The developed model is considered safe in terms of mechanical strength. The porous region does not bring significant effect on stress distribution but produces a considerable amount of compressive strain.
