Abstract
Numerical investigations with regard to the subtrochanteric fracture risk induced by three alternative methods for the treatment of femoral head necrosis are outlined in this presentation. The traditional core decompression technique will be compared with minimal invasive multiple low diameter drillings and the implantation of an innovative tantalum implant. With emphasis to the newly introduced computational strategies and modeling approaches, the modeling of critical loading conditions as well as mesh convergence is outlined in detail. In addition to the immediate postoperative fracture risk, the long-term stability of the different approaches for treating femoral head necrosis is predicted by performing well-established bone remodeling simulation techniques. The computed results are augmented for results obtained from clinical experience.
