A false profile (FP) radiograph of the hip. Showing the criteria of a sufficient FP view radiograph: (1) the distance between the two femoral heads should be between two and three thirds of the diameter of the targeted femoral head. (2) The same vertical line could be drawn from the center of the femoral head through the axis of the femoral neck and the femoral shaft. (3) The lesser trochanter minor is visible posteriorly.
