a contusion can be any kind of bruise. i think they are basically synonymous, but i was under the impression that a bone contusion is more serious than a muscle or cutaneous/subcutaneous contusion.
is b-dog's injury definitely bruised bones in his spine? because that's fucked up news. spinal contusions (while not as serious as most spinal injuries) are really really painful and can be pretty debilitating. i don't like to complain/rant about x-games that much, those jumps really were too close together
PS that was the most gutter game of SKATE ever. epidemic style illness, for real.
