femur breaks are very dangerous too. And I think it would be IM nailed. Not a doc here, but I have heard that the break tends to swivel if torqued the wrong way so they have to do some screwing too (like a lazy suzan with one part of the leg going one way and one going the other.) The problem with possible escaping marrow, and also the fact that a major artery is right there makes it very dangerous. If it is comminuted ( lots of fragments and not a clean break) it is even worse. When a bone is broken it is razor sharp until the osteoblasts "soften the edges," so you can literally cut yourself up inside (it happened to me because my leg twisted around when it broke). I sort of side with the folks who say more than 3 days in the hospital. Also the wasting and muscle loss really takes a lot of your energy, as your leg literally eats up all building supplies in the area. I don't see how people can get up after only a few days. Maybe someone with a crack, but not someone with a break that requires nailing. The majority of your energy, liquids and building supplies goes to the injured area, and the pain is intense . you are totally jacked up on hydrocodone or something for at least a week after, sometimes 2. Oh well, I'm not a doctor or nurse and have only had broken tib/fib, so I'm just adding my 2 cents worth.
