The radial head appears to resemble a knob on a pole rather than a funnel shape. The smooth contour of the radial head as one proceeds from the epiphysis to the metaphysis should be carefully inspected. Any angles noted in this smooth progression may represent a fracture, especially if the clinical findings confirm this.
