Biomechanical Analyses of the human musculosceletal system

The connection both to the human nature and to medical methods opens new dimensions concerning the research in the field of applied mechanics. The field of activity Biomechanical Analyses of the human musculosceletal system of the Institute of Applied Mechanics (FAM) deals with computer-illustrations of humen bone structures and the simulation of work movements up to the development and optimisation of active implants for fracture healing.

To warrant an individual modelling for each patient, radiological image data especially computed tomography data (CT-Data) are used to get a computer-modells of the bone-structures. That way CAD (Computer Aided Design) Models as well as FE (Finite Element) Models, which are necessary for the simulation, are generated. Concerning the FE-Modelling, the CT-Data do not only supply the bone-geometry. Furthermore essential information about the local stiffness distribution inside the bones is provided.
		Modelling based on CT-Data

As regards the processing of the models, especially the simulation of physical strain and damages as a result of both ordinary activities and sports are important. With the aid of these computer models it is possible to simulate very complex movements and physical strains such as a knee bend, for example. That way injury risks can be estimated and also medical treatments can be improved.
		FE-Simulation of physical strain

In the case of a damage like a fracture, very often the use of implants is inevitable. In this field FAM contributes a valuable part concerning the optimisation of already existing implants and prostheses as well as the development of a new active implant (intelligent healing device).
