It is possible to break top bones and still walk. When I was a teenager my horse stepped/fell on my foot. We went orthopedic surgeon, he said in adults surgery was pretty the only way to fix that kind of break. But he was hesitant for surgery because of growth during the healing, so it was monitored through the next and final growth spurt. All I had to was keep it wrapped and took it easy for two weeks and kept it wrapped a few months as I went about normally. Now I am sure with technology and better surgeries I would've had surgery next to immediately. It's simple if you don't let it go.
