The correct answer is:
The planning recommended by Sugioka involves anteroposterior and true lateral radiographs should be performed. For the true lateral radiograph, the patient should be positioned supine, with the hip in precisely 90 degrees of flexion and 45 degrees of abduction and with neutral rotation. The preoperative lateral view radiograph shows the A-P view of the femoral head as it will appear after 90 degrees of posterior rotation. In contrast, a preoperative lateral view in a reversed position shows the A-P view after 90 degrees of anterior rotation.
