Problems solved by technology

[0011] The inaccuracy of the point of entry also compounds the problem of slipping which is often the case with the rounded end of the drill bit, and thus makes it difficult to set another borehole adjacent to one formed earlier
Inaccurate distal locking can lead to premature failure and breakage of the nail passing through the nail hole, breakage of the screw, or breakage of the drill bit in the bone

Abstract

The present invention discloses a system (1010, 1110) for identifying markers. The system includes a field generator (1016, 1116) for generating a magnetic field, an orthopedic implant (1030, 1130) positioned within the magnetic field, the implant having at least one marker (1028, 1128), Removable detector (1029, 1129) with first magnetic sensor (1026, 1126), marker identifier (1016, 1116) with second magnetic sensor (1020, 1120), and processor (1012, 1112) , the processor for comparing sensor data from the first sensor and the second sensor and using a set distance to calculate a position of the marker identifier relative to the at least one marker. The invention enables blind targeting of one or more markers.
