Oblique axial (a) and coronal (b) proton density (PD)-weighted MRI images in a 30-year-old man with a cam deformity. There is an osseous protuberance (arrows) at the femoral head–neck junction anterolaterally, with loss of offset of the femoral head–neck junction. The physeal scar extends lateral to the circular region of the femoral head (dashed circle) on the coronal image
