Male Group: In this study, the male group consists of 200 healthy adult men selected from hospital radiology archive records, who have undergone pelvic computed tomography (CT) scans for various reasons. These individuals were chosen excluding those with pelvic fractures, anatomical abnormalities, or severe osteoporosis. The age range of the male group is between 18 and 65 years, with a median age of approximately 39.4 years. Analyses conducted on the male group focus on concepts such as the Both Column Fixation Corridor (BCFC) and Both Column Screws (BCS), evaluating the feasibility, gender-specific anatomical differences, and potential advantages of this new fixation technique.

Female Group: Similarly, the female group comprises 200 healthy adult women who have had pelvic CT scans for any reason, selected from hospital radiology archives. Like the male group, these individuals meet the specific criteria set for the study. The age range for the female group is also between 18 and 65 years, with a median age comparable to that of the male group. The analysis of the female group centers on the feasibility of applying BCFC and BCS, taking into account the unique anatomical structures of the female pelvis and their implications for surgical planning. The work on this group aims to enhance the understanding of gender-specific anatomical variations and integrate this knowledge into surgical practices.

The intervention aims to simulate a percutaneous fixation technique that could be applied in a real surgical environment, offering insights into the potential for personalized surgical planning and optimization of outcomes for patients with acetabular fractures. This virtual approach allows for the exploration of various screw placement strategies without the ethical and practical constraints of direct clinical experimentation.

This measure evaluates whether the axial fluoroscopic image of the BCFC can be successfully demonstrated across all participant populations, regardless of gender, and whether it's feasible to place two BCS within the BCFC, one anterior and one posterior, in the surgical treatment of pelvic and acetabular fractures. It also examines gender-specific anatomical variations associated with the BCFC and BCS and their implications for surgical planning.
