A system and method for identifying the position of the distal end of a bone guide wire is provided. A position and orientation of the proximal end of the guide wire is identified with the aid of a medical, optical tracking and navigation system and a reference device on the proximal end of the guide wire. The orientation of a bone in which the distal end of the guide wire is located is identified with the aid of the medical, optical tracking and navigation system and a reference device on the bone. By means of the ancillary conditions for the course of the guide wire, which are given by the position and orientation of the proximal end and the orientation of the bone, and by taking into account the physical properties of the guide wire, the position of the distal end of the bone guide wire is identified with the assistance of a computer.
