Three-Dimensional Analysis of the Characteristics of the Femoral Canal Isthmus: An Anatomical Study

Figure 2

In the femur-customized coordinate system, the anatomical parameters of the femur and its isthmus tube were determined, including the femoral length (F-length), isthmus height (I-height), distance between the isthmus and LT in the -axis (LI-distance), isthmus tube length in the -axis (T-length), isthmus tube length (T-length), and the intersecting angles between the axis of the isthmus tube and the horizontal plane in the coronary plane (AP-angle).
