[New information about the biomechanics of fracture fixation].

The better knowledge of the biomechanics of bone tissue and fracture healing resulted in the development of the AO principles and its methods of treatment. I have demonstrated on the femora of rabbits that the consequence of progressive dynamization versus the current unchanging stability of fracture fixation was a more rapid healing. According to our knowledge the more elastic, dynamizating or dynamizable fixation of the fracture are the methods of future. The new biodegradive implantates make not only their removal superfluous but help the fracture healing, too.
