Fig. 3From: Mal-angulation of femoral rotational osteotomies causes more postoperative sagittal mechanical leg axis deviation in supracondylar than in subtrochanteric proceduresMal-angulation of the osteotomy planes. Mal-angulation of the baseline osteotomy plane was performed along the standardized coordinate systems in the frontal plane around the x-axis (blue) and in the sagittal plane around the z-axis (green) in steps of +/− 5°, +/− 10°, +/− 15°, +/− 20°, +/− 30Back to article page
