The authors present an original solution for distal screw fixation in locked nail intramedullary osteosynthesis, traditionally carried out with image intensifier. The system includes the determination of an electromagnetic field produced by a microbobbin placed in the hole and, thus, coaxial with it. The study, conducted through a probe equipped with special magnet-resistant sensors capable of picking up electromagnetic variations, is based on the same principle as a compass. In addition to being effective and simple, the method avoids exposure to ionizing radiations required for the search for holes.
