Computational fluid dynamics modeling of insertion and advancement of a reamer into the intramedullary canal of a long bone

The effect of reaming velocity on the pressure distribution within the bone was investigated numerically by solving the full three-dimensional momentum equations together with the continuity equation using the finite element technique. Viscosity was also varied to obtain a pressure envelope. It was found that all the experimental data follow the same trends as the envelopes predicted by the finite element model. It was clear that an increase in …
