The animals were divided into 3 study group. All rabbits received the same type of trauma to the femur in the subtrochanteric region - transverse fracture, followed by reposition and fixation of bone fragments by metal rods. Animals of the control group was performed intramedullary metal osteosynthesis with a rod of stainless steel (316L); animals of the second group of rod with a titanium-vanadium alloy (W-6) and the animals of the third group of the rod of zirconium-titanium alloy (Zr-Ti). On the basis of data from clinical and radiological improvement of the formation of callus in the area of the fracture and radiographic manifestations of changes in the bone fragments is determined that for the fixation of diaphyseal fractures of the femur are the most physiologically and biomechanically justified is the use of intramedullary rods-clamps made of alloys with a low elastic modulus and its approximation to the modulus of elasticity of the bone tissue. It is developed at the Institute for metal physics of NAS of Ukraine low modulus -(Zr-Ti) alloy physical and mechanical properties as close as possible to such properties of bone tissue that, in turn, provides the best conditions for the biological existence of hydrodynamic effects of elastic deformation and has a positive effect on the dynamics of regeneration at the site of fracture and the processes of reconstruction of bone tissue. An experimental study shows the feasibility of the development and introduction into clinical practice of orthopedic specialists of the implants and the basis of low modulus -(Zr-Ti) alloy that will improve the results of treatment of long bone fractures and to reduce the postoperative complication rate.</p&gt;}, number={2}, journal={Reports of Morphology}, author={Brusco, A.
