Abstract

Creating finite element models of various joints in the human body has been extensively researched using computational methods. Validated and verified computational models can give important information about the load transfer through the joint benefitting clinicians and academics. Computational models will allow for conducting virtual experiments and predict possible outcomes of various in-vivo loading scenarios. These virtual experiments have accelerated the development of joint implants, in particular for the hip and knee. Many finite element models have been created of the hip and knee, but less attention has been paid to other joints of the body in particular multi bone joints such as the wrist and ankle. That can be credited to the geometrical complexity of the joints as each bone within the joint will contribute uniquely to the load transfer characteristics as well as interacting with neighbouring bones. Such contact analysis is computationally costly, but with recent advances in computational power and software, these types of simulations are now possible to be carried out with greater level of detail than before. This chapter will describe the methodology for creating a multi bone finite element model focussing on the wrist and demonstrate the clinical applications that such a model can be used for.
