1. A method of creating a model of a patient-specific structure of a cutting block, the cutting block used for assisting an operator in cutting at least one plane in a bone of a patient, the method comprising:

  • obtaining geometrical data of a bone and of an intramedullary canal of the bone;

    determining a penetration of a fixing rod to be inserted in and extending partially out from an intramedullary canal of the bone, the penetration based on the geometrical data of the intramedullary canal of the bone and on a geometry of the fixing rod;

    determining an orientation of a portion of the fixing rod projecting out of the bone relative to the bone based on the geometrical data of the bone, on the geometry of the fixing rod and on the penetration; and

    creating the model of the patient-specific structure of the cutting block using the geometrical data of the bone, a desired position and orientation of the at least one cut plane on the bone, and the orientation of the portion of the fixing rod projecting out of the bone.
