Abstract: The present invention provides a method for generating a bone fixation implant and related preoperative planning. The method comprises a first step of determining at least the orientation and the position of the fixation means, based on a 3D model of the bone fragments. The method may include a second step of defining the shape of one or more bone plates, based on the output of the first step. The method may further include a third step determining tools for applying fixation means during surgery, according the optimized configuration defined in the first step and applying the bone plates from the second step. The method may even further include a fourth step, quantifying construct stability for a given patient following surgery, thereby allowing early weightbearing.
