From: Mal-angulation of femoral rotational osteotomies causes more postoperative sagittal mechanical leg axis deviation in supracondylar than in subtrochanteric procedures

Fig. 6

Effect of decreased postoperative sagittal mechanical leg axis deviation with increased mal-angulation in subtrochanteric procedures. a Subtrochanteric rotational osteotomy in Model 2 using an osteotomy plane with + 5° sagittal mal-angulation. Marked is the sagittal projected 0° axis in black and the femoral head centers for every step of rotation in purple. In grey schematically marked is the relative circle of movement of the femoral head center. b Subtrochanteric rotational osteotomy using an osteotomy plane with + 30° sagittal mal-angulation. In red the femoral head centers for ever step of rotation. Compared to Fig. 6a, the relative circle of movement of the femoral head center is flatter and more in line with the 0° axis
