Respectfully disagree sir....about 2 weeks post fracture the osteoblasts start to repair a fracture and a visible line of repair is evident on plain film. The finding is not subtle. A fracture with a fragment is one of the easiest findings to read on an XRay. In my heart of hearts I just have a feeling that the fans and the betting public were taken for a ride on this one....the horse should never have seen the track at Pimlico.
