In order to be able to ascertain the position of the bone in the body without complicated procedures in a process for the preoperative determination of the positioning data of endoprosthetic parts of a central joint relative to the bones forming the central joint, a respective outer articular point is determined by way or movement of the bones about a respective outer joint which is located at the end of the two bones facing away from the central joint. An articular point is determined for each of the two bones in the area of the central joint, and a direction characteristic for each of these bones is determined by way of a straight-line connection of the two articular points obtained in this manner for the two bones. The orientation of the endoprosthetic parts relative to this characteristic direction is then determined. Apparatus for carrying out the process is also provided.

A plate probe and associated system and method for facilitating the orientation of an osteotomy and the implantation of an artificial joint component during arthroplastic surgery requiring an osteotomy. The probe comprises a coupler and a plate. The coupler is configured so that it can be connected to a position tracker, such that the position and orientation of the plate can be determined from the position of the tracker. The plate is configured so that it can be inserted into an opening of a bone-cutting mechanical guide, which is generally designed for receiving and guiding a surgical saw blade during a cutting operation.
