Magnetically locatable implants, such as fixation systems, anchor plates or the like, and the determination of their intracorporeal position by means of a medical device comprising at least one impedance-measuring device and a device for generating and coupling a magnetic field which are both connected to at least one intracorporeal electrically conductive probe, the impedance-measuring device being additionally equipped with at least one connector for connection to the magnetically locatable implant. The device is particularly suitable for determining the position of magnetically locatable pedicle screws and the like in a spinal column fixation system with rod-shaped electrically conductive probes as stabilizers.
