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

Fig. 4

Measurement of the sagittal mechanical leg axis. a Starting position with a neutral alignment. b 30° of internal rotation in Model 2 after osteotomy with a mal-angulation of the subtrochanteric osteotomy plane of + 30° in the frontal plane. c 30° of internal rotation in Model 2 after osteotomy with a mal-angulation of the supracondylar osteotomy plane of + 30° in the frontal plane. Schematically marked is the measurement of the altered sagittal mechanical leg axis
