This retrospective observational study aims to define the optimal antegrade entry point for screw placement in the anterior column fixation corridor (ACFC) of the acetabulum. Using fluoroscopic visualization techniques, the study examines computed tomography (CT) scans from 500 healthy adult patients to simulate screw placement and measure anatomical parameters. The goal is to determine patient-specific entry points and to assess the feasibility of screw placement using axial fluoroscopic views. The study also investigates gender-specific anatomical variations to provide insights for safer and more precise screw placement during anterior column fixation in pelvic surgery.
