1. A method of determining an indicator for the stability of a bone implant, the method comprising the steps of: Providing a two- or three-dimensional image of a bone at a location where a bone implant is planned, Determining a bone structural parameter at said location from the two- or three-dimensional image, Providing implant stability data which is related to data representing the bone structural parameter, and Determining, from the determined bone structural parameter and from said implant stability data, an indicator for the stability of the planned bone implant after implantation at said location.
