Abstract: Forty-five third-generation human right femur models (Synbone) were used. The results of fixing the new H beam implant and cannulated screws were compared by using biomechanical test with various stabilizes loads. 3 types of fractures were created in the femur models according to the standard Pauwels classification. In 2 different implants after linear fixation of the fracture to assess the hardness and stability of the bone models, the femoral bone models were subjected by mechanical tests based on static and dynamic pressure and torsional tests. As a result of tests, no significant difference was found (respectively, p = 0.046, p = 0.127) in tests of static pressing and torsional between the sizes of the rigidity of the two methods of fixation. Under dynamic load conditions, the sizes of BL and the new implant system, compared with the cannulated screw significantly decreased (p = 0.041), and when comparing the change in the location of the sizes of CL-, significant differences were found (p = 0.018). As a result, if there is no significant difference under static and dynamic load, instability of the new system with respect to the classical system is established. The fact that the early load on the surface surrounding the operating area is not allowed in practice, the reliability of the new implant is shown from a clinical point of view. We consider using the new H beam implant as an alternative of cannula screws of osteosynthesis in the surgical treatment of femoral neck fractures. © 2019 Ministry of Health. All rights reserved.
