Using the reslice function of the Mimics software, the cross-section vertical to the screw is reconstructed. R refers to the radius of the containable biggest circle. r refers to the radius of the hollow screw. T refers to the distance between the center of the containable biggest circle and the screw center. a shows the cross-section reconstructed on the acetabular notch. b shows the cross-section when the distance of screw and iliopectineal line arc roof is the minimum
