Objective. Explore and analyze the probability of occurrence of pathological fractures with degenerative-dystrophic diseases of the skeleton, determine the impact of new original designs of implants and implants with loads in the area of proximal femur, assess the strength characteristics of bone-implant prophylactic used for proximal femur using the original designs of implants and implants. Methods. Develop and propose original designs reinforcement implants and implants to which the patents of the Russian Federation and the method of their application. In the bone were virtually introduced original designs of implants in 8 different versions, mathematical modeling, using models of reinforced systems bone-implant proximal femur by laser scanning. Implemented testing various options post-mortem samples stiffening bones and artificial bones mannequin to complete destruction of bone-implant system. Results. Through mathematical modeling established that when loaded on proximal femur, causing distortion in the cranial and caudal cervical parts voltage increases, which results in a fracture at critical points. When this line fracture has direction from the periphery, where there is the maximum voltage inside. Bench test results indicate that the horizontal load on the head along the axis of the diaphysis of the femur neck reinforced strength increased to 93 %, and for vertical up to 152 % depending on the combinations of input implants. Conclusions. Implants when used for proximal femur should be located closer to longer-term cortical layer and further away from the central axis of the femur: the voltage of the external load strain partially redistributed in item reinforcement. All options studied reinforcement increases the strength of bone-implant system as when vertical and horizontal load, with the best effect demonstrated system with the greatest area of contact (screw-corkscrew).
