Abstract
In order to improve the precision of determining the articulation point with a method for determining an articulation point of two bones, which are connected by a joint and are connected to pivot relative to one another around at least two non-parallel rotational axes, wherein the two bones are moved relative to one another, measured values describing the movement of a point of a bone in a reference system of the other bone are recorded, a rotational axis describing the movement as rotation is determined from these measured values for a plurality of parts of the path or respectively for one of a plurality of consecutively recorded paths, it is proposed that the deviation in orientation is calculated for the differently oriented rotational axes determined in this way and from the differently oriented rotational axes an articulation point is calculated only when the deviation in orientation of the rotational axes exceeds a specific value.
