Abstract: A system (10, 110) for identifying a landmark is disclosed. The system includes a field generator (16, 116) for generating a magnetic field, an orthopaedic implant (30, 130) located within the magnetic field, the implant having at least one landmark (31) and a first magnetic sensor (32) spaced apart from the landmark, a landmark identifier (18, 118) with a second magnetic sensor (20, 120) and a processor (12, 112) for comparing sensor data from the first and second sensor and using the set distance to calculate the position of the landmark identifier relative to the at least one landmark. The system allows for blind targeting of one or more landmarks.

Abstract: Systems (10, 110, 1010, 1110) for identifying landmarks (31, 131, 1028, 1128) on orthopedic implants (30, 130, 1024, 1124) are disclosed. The systems (10, 110, 1010, 1110) include a field generator (16, 116, 1016, 1116) for generating a magnetic field and an orthopedic implant (30, 130, 1024, 1124) located within the magnetic field. The implant (30, 130, 1024, 1124) includes at least one landmark (31, 131, 1028, 1128), an optional removable probe (1029, 1129) and a first magnetic sensor (32, 132, 1026, 1126).
