Lecture title: "Poröser Mensch. Von den Wirbeln zu den Muskeln"
To satisfy our curiosity, we typically perform experiments. This is practical for many things, but if it comes to the human body, we often face substantial technical and, more seriously, ethical challenges! For example, understanding the mechanics of the musculoskeletal system would lead to improved outcomes of interventions such as vertebroplasty – a procedure during which bone cement is injected into a vertebra to stabilise the respective vertebra and regain long-term function. Depending on the experiences of the surgeon, he/she might have an ok idea on the impact of this intervention on the overall system. The less experienced one, however, might want to explore first different scenarios. However, he/she has only one trial! Simulations could provide one way to assess the outcome of different scenarios. To make this vision come true, we specifically develop novel computational methods to predict the outcome of vertebroplasty as well as predicting the impact on its surrounding tissues, e.g. adjacent vertebra and the musculoskeletal system. As you might guess from knowing that our body mainly consist of water, is often a mixture of different structures, and, of course, from the title of this exhibition, we consider biological tissues as porous media. This talk will dive into the world of how simulations can be used to predict the mechanical behaviour of biological tissues, exemplified by modelling bone injection processes and the mechanics of the musculoskeletal system.
About Oliver Röhrle
Oliver Röhrle is the Director of the Institute for Modelling and Simulation of Biomechanical Systems and Professor for Continuum Biomechanics and Mechanobiology at the University of Stuttgart. His research focuses on various aspects of the musculoskeletal system, e.g., on novel chemo-electromechanical skeletal muscle models, biophysical recruitment models, virtual EMG predictions, continuum mechanical homogenisation techniques for skeletal muscle tissues and forward-dynamics simulations of multi-muscle systems using three-dimensional continuum-mechanical skeletal muscle models. Moreover, he is interested in dental applications.
