Claim One:
1. A method for measuring a position of a medical implant relative to an associated anatomical body part using an associated inserter or impactor device operably coupled with a reference structure and having an at least partially known or previously determined geometry or at least partially known dimensions, the medical implant being axially symmetric about an axis defined by the medical implant, the method comprising: releasably connecting the medical implant with the associated inserter or impactor device such that a relative alignment between the axis defined by the medical implant and the associated inserter or impactor device is fixed or determined and with a rotational position of the medical implant about the axis being arbitrary; acquiring positional or landmark information regarding the associated anatomical body part by using a pointer to which a reference element, an inertial sensor, or a reference element and an inertial sensor is connected; calculating an orientation of the axis defined by the medical implant and a position of the medical implant along the axis using a navigation system and the reference structure operably coupled with the associated inserter or impactor device; and comparing the calculated orientation of the axis defined by the medical implant and the position of the medical implant along the axis with the acquired positional or landmark information regarding the associated anatomical body part in order to measure the position of the medical implant relative to the associated anatomical body part.
