It's common to use "fracture" to describe a broken bone. But you can also have different fractures, such as a kidney fracture etcetera. Docters etc. for example rarely say that you have a broken bone. They just that it's fractured. There are lots of way to describe broken bones. You can just say 'broken bone' or 'fractured bone/bone fracture' or you can refer to the bodypart you've broken: "broken leg, broken jaw, broken arm, broken wrist, broken ankle" and by using fracture: "leg fracture, jaw fracture, arm fracture, wrist fracture, ankle fracture, skull fracture, etc."
Technically fracture is a better way to describe the problem because bones seldomly snap right through. Especially when talking about facial fractures. If someone's head is actually broken in two pieces, it's kind hard to fix that. That's why they say "fractured skull" which means that the bone tissue is damaged/teared/partially broken.
P.s. I have a habit of googling words I'm explaining to check if there's an appropriate picture or website. But in this case: Don't search for images! :P Unless you have a strong stomach of course. ;)
