Fig. 1 Diagrammatic representation of hip viewed in the transverse plane. 1 shows a hip with normal morphology. The shaded area in two represents a cam abnormality; as the hip internally rotates this will impinge on the anterior acetabulum.

Fig. 2 Diagrammatic representation of how to measure an alpha angle in a hip with a cam deformity. Line 1 is drawn between the centre of the femoral head and the anterior point where the bony contour exceeds the radius of the head. Line 2 is drawn along the axis of the femoral neck, between the narrowest point of the neck and the centre of the femoral head. The alpha angle is measured between line 1 and 2.
