At the Test Laboratory of CITO five modern devices for transosseous osteosynthesis were studied to evaluate the fixation stability in comminuted fractures. Firmness was defined in compression, twisting as well as frontal and sagittal bends. In all planes the highest level of fixation stability was found in RAPFIS device. Design peculiarity of that device provided the additional increase of fixation stability by roads insertion into bone fragments at an angle and diminution of the «bonefixative» distance (console) that almost 3 times improve the fixation stability.
