Slipped capital femoral epiphysis: Anteroposterior radiograph

This anteroposterior radiograph of right slipped capital femoral epiphysis demonstrates widening, lucency, and irregularity of the physis (arrow), blurring of the junction between the metaphysis and the growth plate, diminished height of the epiphysis (double arrow), and increased density in the proximal femoral neck (arrowhead, the "blanch sign of Steel"). In addition, note that Klein line (dashed line) passes along the superior edge of the epiphysis of the femoral head rather than intersecting the lateral portion (as on the left).
