Abstract

The present invention relates to a method for measuring or verifying the position of a medical implant located in an anatomical body part(s) and/or structure(s) relative to the body part(s) and/or structure(s) or specific points, landmarks or planes of the same, wherein a device is provided which has an at least partially known or previously determined geometry or at least partially known dimensions and is connected to the medical implant; positional or landmark information regarding the anatomical body part(s) and/or structure(s) is acquired; the position of the medical implant is calculated using a navigation system and a reference structure which is or can be connected to the device; and the calculated position of the medical implant is related to or compared with the acquired positional or landmark information regarding the anatomical body part(s) and/or structure(s) in order to measure or verify the position of the medical implant within or relative to the anatomical body part(s) and/or structure(s).
