Mathematisch-kinematische Methoden in der Gelenkendoprothetik

: By the use of mathematical and cinematical methods a new understanding for the construction as well as for the implantation-techniques for endoprosthesis can be developed. With these methods the size of the natural motion and the process of the natural motion can be studied. So we get better informations about the natural motion and we can deduce criterions for the construction of endoprosthesis, for we can compare the motion of a model with the natural way of motion. So we can estimate preoperative the efficiency and the maximal load of the prosthesis as a result of incorrect motions. Such incorrect motions can be caused or can be avoid by the construction of the endoprosthesis as well as the implantation techniques.
