I broke my wrist 2 years ago pretty bad. I didn't have health insurance at the time so I didnt get the surgery I needed, I also didnt get any kind of brace or cast or rehab. I just got vicodin....
Now I may not be able to lift a whole lot of weight, and it gets sore from time to time, but at it's worst I could still play basketball(it's my non-shooting hand as well)
It's one of those things where 1-70lbs does absolutely nothing at all to it, but once you get into higher weights I really feel it. Unless someone lands on it or he falls on it he really shouldn't have to worry about it affecting him. He has the best doctors and tons of rehab he should be fine.
