Well, my sister fractured my right clavicle when I was 5 (she was 14, and a mean, mean bigger sister). I did no rehab other than wearing a sling for a month or 2, if I remember. I may have been given a few exercises as well. Moral of the story is: Today (21 years later) my right arm hangs noticeably (to me, at least) about an inch lower than my left, I can't do dips at all, and front raises are an "only if I ask my shoulder politely" type of manuever.
Your best bet is to get to a qualified sports chiropractor or physical therapist and do what they say, religiously. Good luck.
