the wrist owns the one bone that is the hardest to heal in the body and that's the scaphoid bone because it's it's like a carob coated cashew it's almost all in encompassed by cartilage so there's only a couple of little areas where tiny blood vessels can get into that bone and unlike almost all the other if not all the other bones in our body the we don't have what we call anti-grade flow into that bone it leaving the heart going down through the arteries and the capillaries and going into the bone from a point A distally to point B it goes in retrograde so if you if you crack that bone in the middle at Baseline it has very little blood supply then you crack it and you probably disrupt the Bloods exactly and so there's a high risk of non-union
