Method an device for providing information after insertion of a prosthesis in a hip joint comprising prosthesis stem, and a prosthesis cup and based on this information the position of the components of a hip prosthesis is provided. The prosthesis stem and the prosthesis cup or the part of the body in which the prosthesis is provided can include markers that can be shown on an X-ray picture. The X-ray picture is downloaded in an image processing program having assistance lines for determining the position of the prosthesis components. The X-ray picture is downloaded automatically or manually in the image processing program. The assistance lines are brought into coincidence with the images of the markers on the X-ray picture. Thereafter a calculation unit in the image processing unit calculates the angles for the respective prosthesis components. |
