title: [Remarks on biomechanics of external fixation.].
abstract: In our experimental study we report results of a measurement of the stiffness of different types of external fixators. In model of external fixation of the femur the mechanical properties of Hoffmann, Wagner, Ilizarov and Poldi 7 aparates were evaluated in model of external fixation of the tibia the properties of the different configurations of the unilateral frame and of the combined unilateral frame and bilateral frame were evaluated. Our results have shown the importance: - the stiffness of an applied frame, - the proper interconection of the used configura tion of the apparatus (frame), - the number and placement of an individual im plants screws, pins. Some of the obtained results were applied in our clinical practice. Key words: external fixation, biomechanics.
