Биомеханическое обоснование устройства и способа стабильного остеосинтеза многооскольчатых переломов дистального отдела плечевой кости

The paper presents the results of experimental studies on determining the stabilizing possibilities of the proposed model of fixation of the distal humerus. In particular it is found that the developed device for osteosynthesis of comminuted humerus fractures, based on the principle of unidirectional compression of bone fragments, in the experiment showed better fixing performance in comparison with pin osteosynthesis at loads exceeding 20 H, which means greater stiffness in the «bone — fixator» system, and therefore greater stability of bone fragments. Effect compressing bone fragments can be enhanced by almost half, in the use of thicker 2-mm needle Ilizarov wire instead of thin Kirschner wire. Our calculations show that osteosynthesis device developed by us effectively stabilizes bone fragments.
