Strength characteristics of the proximal femur in conditions of internal force shunting

The present research describes a method of surgical prophylactic reinforcement of the proximal femur in elderly patients suffering from various diseases that cause degenerative and dysplastic processes in bone (oncology, osteoporosis, cartilage and fibrous dysplasia, etc). These processes cause pathological fractures. Original reinforcement implants (Russian Federation patents number 91845, 98901, 101351, 121725) are installed in the intact bone of the proximal femur to prevent its fractures in case of low-energy trauma, thereby increasing bone strength. Preventive reinforcement technique has a mathematical and economic feasibility. Increasing of the strength of the proximal femur, reinforced by implants from nanostructured titanium, is proved by bench tests.
