Abaqus was used to model the push-out load between a hip prosthesis stem and bone with bone-stem contact area and interference, stem-bone friction coefficient and viscoelastic material properties as variables. The push-out loads were used with a device that maps out the geometry of the femoral intramedullary canal to aid a surgeon with optimal prosthesis size selection in real time during hip replacement surgery.
