Новая концепция в профилактической ортопедии. Предупреждение патологических переломов проксимального отдела бедра путем хирургического армирования кости

Abstract

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%.
