New biomechanics study of hoffmann® external fixation.
While remaining faithful to the Hoffmann Vidal external fixator, the authors have been trying for the past 15 years to improve both the stiffness and versatility of the double frame device. Taking into account the different btomechanical studies about the double frame made by different research laboratories, the authors have improved the double frame device by certain modifications in the pins and rods configuration. They have thus obtained the quadrangular triple frame mounting and the triangulate triple frame. The latter device is comparable to a "chalet," being very rigid under any demands but also very versatile due to its smaller dimensions.
