Radiographs of a 16-year-old achondroplasia patient not exhibiting flexion contracture after femoral lengthening. a Initial radiograph of the patient. The patient underwent simultaneous bilateral femoral lengthening to gain 6 cm (lengthening percentage of 19.0%). b Postoperative radiograph showing no significant changes of spinopelvic parameters in comparison with initial radiograph
