Abstract (English):
The paper is dedicated to the pilot study of the surgical ways of preventing fractures of the hip among elderly patients suffering from various diseases that cause destructive‐dystrophic changes of the bony tissue (osteoporosis, cancer, cartilage and fibrous dysplasia, etc.) and are the cause of pathological fractures. The research involves the identification of people at risk, the development of preventive techniques and original reinforcement implant designs, the definition of a methodology for mathematical modeling and bench tests to determine the strength of the original implant reinforced hip. Studies have shown that the index of strain in the bone is considerably lower than on its surface (closer to longer‐term cortical layer), and when the load increases, it results in the development of a fracture. As a result of the reinforcement of the bone with different implants the index of strain at critical points is increases up to 11.6% ‐12.1. The bench tests proved that the preventive reinforcement to prevent fractures in low‐energy trauma can increase the strength of bone‐implant, depending on the type, design, quality, implant and method of its introduction up to 23‐93%.
