Mine had surgery two weeks ago. The mri showed a separation, but his doctor said he wouldn't know how severe the tear was until he got in there. I trust this doctor. He is the surgeon for the school and the US olympic ski team. He starts pt today with a therapist that has experience with these injuries and baseball players. I think who is doing the pt is very important. The goal is to be soft tossing by september, and hopefully close to full strength by november. Doc made it clear there are no guarantees. Doc said proper stretching prior to throwing is key to prevent these injuries.
