Three-Dimensional Analysis of the Curvature of the Femoral Canal in 426 Chinese Femurs

Figure 2

The simulation experiment to verify the interaction between the torus and inner femoral cortex. A torus was created using the canal’s centerline and femoral isthmic diameter. Three orthogonal planes were created. The first curved plane (plane D) was part of a cylinder surface (left side), which was perpendicular to the RFC plane (plane A or B). The axial plane (shown in the video of Supplementary Material) was perpendicular to plane (D) and plane (A) or (B), simultaneously, and moved along the canal’s centerline in the video recording. After reformatting the CT scan along the canal’s centerline, the femoral canal became almost straight along plane (C), which was created after stretching plane (D).
