EA Skate what are milestones?

Ive checked everywhere and no one seems to answer any one who asks this question. But since im now trying to finish everything left in the game, but idk what milestones are. Is there a list of them? For example i wanna get the achievement for getting all the medical milestones, so what are the medical milestones. I heard something about breaking each bone 3 times and im sure ive done that twice already lol. And eventually i wanna have the complete all milestones achievement.

Many thanks.

To view all of you milestones go to your backpack and select logbook. Then go to records, then milestones. It will show you the 27 milestones.
