does any one skate? btw i just smacked my shin really hard
When the bones separate completely, that's just called a complete fracture. A compound fracture is when the broken bones cause other injuries (such as protruding through the skin) which can expose bone tissue to infection and whatnot.
I don't skate anymore, but I used to skateboard in middle school (but that was back in the 90's).
