Abstract: BACKGROUND: Navigational simulator use for specialized training purposes israther uncommon in orthopaedic and trauma surgery. However, it revealsproviding a valuable tool to train orthopaedic surgeons and help them to plancomplex surgical procedures. PURPOSE: This work-s objective was to assesseducational efficiency of a path simulator under fluoroscopic guidance appliedto sacroiliac joint percutaneous screw fixation. MATERIALS AND METHODS: Weevaluated 23 surgeons- accuracy inserting a guide-wire in a human cadaverexperiment, following a pre-established procedure. These medical trainees weredefined in three prospective respects: novice or skilled; with or withouttheoretical knowledge; with or without surgical procedure familiarity. Analysedcriteria for each tested surgeon included the number of intraoperative X-raystaken in order to achieve the surgical procedure as well as an iatrogenic indexreflecting the surgeon-s ability to detect any hazardous trajectory at the timeof performing said procedure. RESULTS: An average number of 13 X-rays wasrequired for wire implantation by the G1 group. G2 group, assisted by thesimulator use, required an average of 10 X-rays. A substantial difference wasespecially observed within the novice sub-group N, with an average of 12.75X-rays for the G1 category and an average of 8.5 X-rays for the G2 category. Asfar as the iatrogenic index is concerned, we were unable to observe anysignificant difference between the groups.
