Background Wire navigation, or the ability to target a wire to a precise location through an osseous trajectory, is a fundamental skill in orthopaedic surgery.
Aims Develop a radiation-free electromagnetic sensor-based wire navigation simulator in a proximal femur model Determine if simulator training improves performance in novice (PGY-1) surgeons Compare novice and expert (senior residents/staff) surgeons
Discussion TrakStar wire navigation simulator can distinguish novice and expert surgeons – Increased TAD in novice surgeons Practice on the simulator leads to decreased time and fluoroscopic shots, but no difference in TAD (actually increased)
Discussion Simulator needs to be affordable, user- friendly, demonstrate validity – Trakstar is expensive – Need further validation studies Currently testing the simulator in graduate students and more senior surgeons
