A technique of providing user guidance for surgical navigation is provided. A method implementation of the technique includes obtaining a predetermined spatial relationship between an optical tracking pattern and a through-hole extending through an implant, obtaining image data of the optical tracking pattern acquired by an imaging unit attached to a surgical instrument, obtaining a spatial relationship between the surgical instrument and the imaging unit at a point in time when the image data have been acquired, determining a spatial relationship between the surgical instrument and the through-hole, obtaining a plurality of predefined spatial relationships between the surgical instrument and the through-hole, and triggering simultaneous display of an indication of the plurality of predefined spatial relationships and an indication of the spatial relationship between the surgical instrument and the through-hole.
