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.
This study focuses on developing and validating a fluoroscopic visualization technique for identifying the optimal antegrade entry point (OAEP) in the anterior column fixation corridor (ACFC) of the acetabulum during pelvic surgery. Using three-dimensional reconstructions from pelvic computed tomography (CT) data of 500 healthy adults, the study simulates screw placement within the ACFC. A cylinder representing the screw is inserted virtually through the OAEP, ensuring that it remains within the confines of the fixation corridor without breaching its boundaries. The study records anatomical measurements, including the corridor's diameter, length, and the angles required for sagittal and coronal plane inclinations to visualize the OAEP.
The study also examines gender-specific anatomical variations, including differences in ACFC diameter, length, and required fluoroscopic angles. By defining patient-specific entry points and establishing a reliable fluoroscopic technique, this study aims to provide a practical and accessible method for anterior column fixation, minimizing complications and improving the safety and precision of screw placement in pelvic surgeries.
This novel approach has the potential to offer a cost-effective alternative to more expensive navigation systems, making it widely applicable in clinical settings.

Counted across the registry records on this site, refreshed daily.
The study population consists of 500 healthy adults, including 250 males and 250 females, aged between 18 and 65 years. Participants were selected based on their pelvic computed tomography (CT) scans, which displayed complete and fully matured pelvic anatomy. Individuals with prior orthopedic surgeries, pelvic fractures, deformities, or any bone pathologies such as rheumatologic diseases, advanced osteoporosis, and bone metastasis were excluded. The study focuses on assessing anatomical parameters and optimal entry points for anterior column fixation using fluoroscopic guidance.

Exclusion Criteria:
This group consists of 250 healthy male adults whose pelvic CT scans were analyzed to define the optimal antegrade entry point and anatomical parameters for anterior column fixation. The fluoroscopic visualization technique and screw placement were simulated to assess anatomical variations and feasibility specific to the male cohort.
Other: No intervention
This group consists of 250 healthy female adults whose pelvic CT scans were analyzed to define the optimal antegrade entry point and anatomical parameters for anterior column fixation. The fluoroscopic visualization technique and screw placement were simulated to assess anatomical variations and feasibility specific to the female cohort.
Other: No intervention
This study is purely observational and does not involve any direct intervention. It utilizes retrospective analysis of computed tomography (CT) scans to simulate the fluoroscopic visualization and screw placement technique in the anterior column fixation corridor (ACFC) of the acetabulum. The objective is to define the optimal antegrade entry point and assess anatomical parameters without performing any physical intervention on the participants.
