Better Insights Needed Into Failure Mechanisms Of Hip Replacements

If a hip prosthesis implanted to replace a worn-out joint itself fails, then what are the reasons? Until now this problem has been little understood: partly due to incomplete records, partly due to insufficient knowledge of the forces acting on the hip replacement. Computation models developed by the University of Twente and UMC St. Radboud can make an important contribution to our understanding in this field, says Prof. Nico Verdonschot in his inaugural lecture as Professor of Implantation Biomechanics at the University of Twente. Such models can, for instance, predict the strength of a bone much better than a specialist can do visually using an X-ray image.
