With that injury the thereapy and doing it correctly is critical. If you dont rehab it correctly, the injury will occur over and over. I dislocated my right side 19 times in 3 years before I finally quit fucking around and took my thereapy seriously.
I've broken about 4 bones and seperated my shoulder, nothing as serious as suddenly having two spleens, but my stoke always returned. Really depends on the type of personality you are. Hopefully snowboarding will be one of your motivations for PT.
