Estimation of cup orientation on intraoperative fluoroscopy in total hip arthroplasty: how safe is the safe zone—an experimental study
While surgical experience did not improve angle estimation accuracy in degrees, it was associated with more accurate identifications of positions within clinically relevant safe zones. Cup design influenced inclination estimation. Our findings emphasize the importance of precise cup positioning in THA and highlight areas for potential improvement in surgical practice and training.
