Abstract

A method for registering an asymmetrical femur implant having a shaft and a collar includes ascertaining a position of a shaft axis associated with the shaft and ascertaining a position of a collar axis associated with the collar. A device for registering an asymmetrical femur implant connected to at least one reference marker is provided. The device includes a detection device for detecting a spatial position of the at least one reference marker and a database in which a geometry of the asymmetrical femur implant is stored. A processor ascertains the spatial position of the asymmetrical femur implant.
