Abstract
A method for forming an implant for a bone including the steps of generating a first general shape for the implant having a length extending along a long axis of the bone, determining an area moment of inertia of a cross section of the implant, determining an area moment of inertia for a cross section of bone coplanar to the cross section of the implant, calculating a percent stress shielding from the area moments of inertia of the implant and the bone, comparing the calculated percent stress shielding to a preset threshold, and iteratively generating additional general shapes for the implant by locally adjusting the cross section of the implant until the calculated percent stress shielding meets the preset threshold.
