Figure 5
A pattern diagram of different radiographic measurements (a, b). (a) A-B and C-D: the tip-cartilage distance of each screw; E-F: the diameter of screw, used for the calibration of measurements; G-H-I: angle of inferior screw, the angle between the lateral cortex of the femoral shaft and the inferior screw. (b) . CTI is defined as the ratio of the thickness of the cortical bone to the diameter of the femoral shaft 10 cm below the tip of trochanter minor.
