"A slipped upper femoral epiphysis (SUFE) can be graded on both AP and true lateral projections."
"AP projection"
"On an AP hip radiograph, a line along the superior margin of the femoral neck (line of Klein) should intersect the lateral corner of the epiphysis."
"AP projection"
"On a true lateral radiograph, the angle (slip angle) that the epiphysis makes with the metaphysis may also be employed (sometimes known as the Southwick head shaft angle) 2:"
