Abstract Different intramedullary implants are used to prevent the fractures of the proximal femur due to osteoporosis or tumors. The aim of the study is assessment of the ultimate load on the femur with a telescopic or isoelastic intramedullary
implant attached in its proximal part on the basis of a finite element modeling. The load on the femur corresponds to the action of a human’s own weight. Assessment of the ultimate load is carried out using the damage parameter for finite element, evaluated by the ratio of the main maximum strain and critical deformation for cancellous bone tissue. It has been identified that after using of the telescopic and isoelastic implants, the ultimate load on the femur increases approximately by 48 % and 81 %, respectively, compared with the intact femur. It is indicated that the fracture localization after implant attachment is observed in the area located below the greater trochanter that corresponds to the results of clinical observations.
