Figure 1: (a) AP radiograph of the right hip. A focal area of subchondral lucency is present involving the superolateral aspect of the right femoral head (arrow). (b) The follow-up radiograph taken 5 months later reveals near complete destruction of the femoral head. (c) CT scan of the right hip in the axial plane shows loss of the femoral head with two bone fragments within the hip joint (arrows).
