I get it a lot with the hip flexor, testing the artificial hip, which is probably going to have to be redone, dammit. When I was a freshman at UA, I broke my left wrist by overrotating on a back flip and throwing my left hand back reflexively to catch myself. I broke the scaphoid bone, which has the distinction of having arguably the worst circulation of any bone in the body. I think I was casted for nine months. A friend of mine, son of one of our BOTs, broke his, they didn't catch it, and he went on skiing for the rest of the season. They had a place in Telluride. The pain drove him in and they x-rayed and did MRIs, CTs, etc. He had gangrene. They ended up having to harvest donor bone from his hip and graft it in. He's OK now...
