    Abstract: A system (1010, 1110) for identifying a landmark is disclosed. The system includes a field generator (1016, 1116) for generating a magnetic field, an orthopaedic implant (1030, 1130) located within the magnetic field, the implant having at least one landmark (1028, 1128), a removable probe (1029, 1129) with a first magnetic sensor (1026, 1126), a landmark identifier (1016, 1116) with a second magnetic sensor (1020, 1120) and a processor (1012, 1112) 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: A system for targeting landmarks on devices such as surgical implants is disclosed. The system can include a field generator for generating one or more magnetic fields, an orthopaedic implant located within the magnetic fields, the implant having at least one landmark, a removable probe with a first magnetic sensor, a landmark identifier and a processor. The landmark identifier can contain a second sensor, or, alternatively, the field generator. The processor can utilize sensor data and, if desirable, field generator and other information, to generate and display the position and orientation of the sensor(s) in preferably six degrees of freedom, and thereby, to generate and display the position and orientation of the landmark(s). The system allows for blind targeting of one or more landmarks. The landmark identifier, field generator and/or drill motor may be disposed in an autoclavable housing.

    Abstract: Targeting sensors for use in targeting landmarks of orthopaedic devices. The sensors include a non-cylindrical mounting platform such as a printed circuit board and at least two mounted or printed sensor coils to provide a low profile sensor assembly which can be placed in a predetermined position and orientation on or in an orthopaedic device. The platform has a non-circular cross-section having an aspect ratio of greater than about 1.5:1. The non-circular cross-section of the platform enables the sensor to be placed in a known fixed position within the implant. The sensor coils may be partially or fully embedded in the platform.

    Abstract: A controlled removable fracture-reducing assembly for reducing a bone fracture. According to one embodiment, a controlled removable fracture reducing assembly includes an implant, a reducer, a buttress, and a locking device that engage a proximal bone fragment and a distal bone fragment. The implant is secured to the distal bone fragment by the locking device. The buttress engages the implant through an opening. The reducer contains a compressing screw that applies a force on the buttress, reducing the fracture. According to another embodiment, the reducer contains a cam mechanism which applies a force on the buttress, which does not engage the implant, that pushes the proximal bone fragment to reduce the fracture. According to another embodiment, the reducer is a jacking mechanism that pushes the proximal bone fragment while pulling the implant and distal fragment to reduce the fracture.

    Abstract: A controlled removable fracture-reducing assembly (10) for reducing a bone fracture. According to one embodiment of the present invention, a controlled removable fracture reducing assembly (10) includes an implant (12), a reducer (14), a buttress (16), and a locking device (18) that engage a proximal bone fragment (2) and a distal bone fragment (4). The implant (12) is secured to the distal bone fragment (4) by the locking device (18). The buttress (16) engages the implant (12) through an opening (30). The reducer (14) contains a compressing screw (24) that applies a force (60) on the buttress (16), reducing the fracture. According to another embodiment of the invention, the reducer (114) contains a cam mechanism (124) which applies a force (186) on the buttress (116), which does not engage the implant (112), that pushes the proximal bone fragment (102) to reduce the fracture. According to another embodiment of the invention, the reducer (214) is a jacking mechanism that pushes the proximal bone fragment (202) while pulling the implant (212) and distal fragment (204) to reduce the fracture.
