There are 17 different types of fractures (thanks google). I've seen no mention of anything other than a simple fracture/break. The fact that he's out there in practice and has a chance to play suggests that his break tends toward the less severe end of the spectrum I'd say.There is no difference between a bone break and a fracture. Fracture is the clinical term for a break in a bone. A fracture can range in severity from a hairline fracture, which is a small crack in the bone, to a compound fracture, which occurs when the broken bone punctures the skin.
EDIT: Guiness you beat me to it I see. Sorry for the repeat...
