The Fictitious Domain Method For Patient-Specific Biomechanical Modeling: Promise And Prospects
Abstract
In this paper we discuss the application of the fictitious do- main method to the numerical simulation of the mechanical processes induced by press-fitting cementless femoral im- plants in total hip replacement surgeries. The immediate concern is to demonstrate the feasibility of the method, its advantages over other competing numerical techniques and its applicability to a wide range of analysis problems in bio- mechanics whose primary input originates from CT- or MRI-collected data. We consider the implantation of a press-fit femoral prosthesis as a prototype problem for sketching the application path of the proposed methodology. Of concern is also the assessment of the robustness and speed of the methodology, for both factors are critical if one were to consider patient-specific modeling. The latter is part of a thrust to develop pre-operative planners enhanced with robust and fast biomechanical feedback. In this communica- tion we present the concepts and report on initial numerical results.
