Figure 3:

Original and processed bilateral long-leg radiographs in a 16-year-old male patient after guided correction of both lower extremities by means of temporary femoral hemiepiphysiodesis. A, Original bilateral long-leg radiograph. B, Exemplary display of the manual reference measurements. For illustrative purposes, the femoral anatomic-mechanical angle (AMA) for the right lower extremity (dashed line) and the hip-knee-ankle angle (HKAA) for the left lower extremity (solid line) were determined by using the in-house picture archiving and communication system. C, Automatically determined segmentation outlines of the femoral (red) and tibial (green) bones. D, Automatically determined anatomic landmarks (the apical circumference of the femoral head [yellow], the center of the femoral head [blue], the centers along the tibial and femoral joint surfaces around the knee joint [orange and green], and the center of the distal tibia [red]). E, Automatically determined mechanical (blue) and anatomic (orange) axes of the femur and tibia. These were used to automatically determine the AMA (right, 4.76°; left, 4.41°) and the HKAA (right, 4.40°; left, 0.57° [both varus]).
