A new external fixation system has been designed based on previous applied research studies. The design criteria generated were focused on both clinical and biomechanical aspects. An increase in frame stiffness was obtained by means of an independent fixation system of the pins, clamp sleeves and striated hinges. Furthermore, surgical technique has been simplified by means of independent adjustment in the three space planes of movement. The use of a previous guide fixator for drilling and pin insertion was eliminated. Finally, a strain gauge monitoring system has been developed to characterize mechanical callus features during fracture healing.... [Leer más...]
