Abstract

The invention relates to a device for the referenced positioning of two reference points (11; 14) situated on a fiducial screw (2) implanted into a bone. Said device comprises (A) a fiducial screw (2) which can be screwed in to a bone (1) and has a longitudinal axis (9), a screw shank (10) and a screw head (22) provided with means (12) for receiving an instrument used to screw the fiducial screw (2) in and out; and B) a pointer (3) provided with at lea st three means (19) which are not positioned colinearly and emit electromagneti c or acoustic waves, where said pointer (3) has a front end (15), a rear end (16) and a longitudinal axis (9). C) The pointer (3) has means (20) at its front end (15) and the fiducial screw (2) at its head (22) which make it possible for the pointer (3) and the fiducial screw (2) to be joined in the direction of the longitudinal axis (9) and concentrically in relation to sai d axis (9). D) thanks to the known length (x) of the fiducial screw (2), the known length (y) of the pointer (3) and the means (20) described under C) it is possible to achieve a defined, local coordination between the reference points (11; 14) on the fiducial screw (2) and the means (19) of the pointer (3) emitting electromagnetic or acoustic waves.
