I would agree that it is most likely a broken sesamoid. It seems almost as if it has calcified to remain that large. Sesamoid injuries are fairly common in racehorses, but it is usually diagnosed, treated(sometimes surgically) and the horse receives rest. The sesamoid injuries I have seen are mostly "lines" or small stress fractures. I have seen a few fully broken/shattered sesamoids, and those horses were treated and retired. I guess the horses in those pictures are examples of what happens when it goes untreated. How terrible. Her poor knees, too! I feel so sad for her, and I'm happy she is being cared for now - you are a very kind-hearted person!
