Brief summary
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.
Detailed description
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.
Interventions
OTHERNo 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.
