Percutaneous antegrade scaphoid screw placement: a feasibility and accuracy analysis of a novel electromagnetic navigation technique versus a standard fluoroscopic method

“…However, reduction of perioperative morbidity and collateral damage is of utmost importance . Inferior screw positioning and cortical breach account for up to 30% of complications leading to non‐union, osteonecrosis, osteoarthritis, pain and inferior functional limitations outcome . As the biomechanical advantage of a centrally positioned screw is well known, accuracy is a matter of importance .…”

“…Minimal‐invasive percutaneous screw fixation represents the gold standard in treatment of dislocated scaphoid fractures . In literature different percutaneous techniques for screw placement with either closed or open reduction using a dorsal or volar approach are reported . However, no significant differences were shown in terms of union and functional outcome .…”
