A<unk>  is a radiographic<unk>  used to measure the severity of a slipped capital femoral epiphysis (SCFE) on a radiograph. It was named after Wayne O.<unk> , a famous surgeon. The<unk>  is measured on a frog lateral view of the bilateral hips. It is measured by drawing a line perpendicular to a line connecting two points at the posterior and anterior tips of the epiphysis at the physis. A third line is drawn down the axis of femur. The<unk>  between the perpendicular line and the femoral shaft line is the<unk> . The<unk>  is measured bilaterally. The slipped side is then subtracted from the normal side. The number calculated determines the severity. Mild is classified by 50°. 12° is the normal control value and can be used in the case of bilateral involvement.
