Zusammenfassung:	A surgical instrument 10 comprises a base member 12 adapted to be attached to a bone, a guide 14 adjustably connected to the base member, a first marker 34 removably attached to the base member and a second marker 36 removably attached to the guide. In navigated surgery, the first and second markers 34,36 enable the position of the guide 14 to be determined relative to the position of the base member 12 and bone, to which it is attached. The guide may have a planar cutting surface 15 for guiding a blade or a circular aperture (115, Fig 3) for guiding a drill.
