Fig. 2From: Mal-angulation of femoral rotational osteotomies causes more postoperative sagittal mechanical leg axis deviation in supracondylar than in subtrochanteric proceduresBaseline osteotomy planes. In black the mechanical femoral axis. In green the baseline osteotomy planes, defined perpendicular to the mechanical femoral axis and positioned in a way that the respective fixation plates (grey) could be properly placed. Standardized coordinate systems in the center of the osteotomy planesBack to article page
