Hi Mike ~ This is my first post on the forum! But your post title most definitely got my attention! I have not had the surgery, but my mother has (70); and I've been helping her with it since then. Now, my mom had her operation under an emergency situation (She fractured/dislocated her humerus in China) Also, I have a friend who has had it, she's 50 - and another friend (a tough-as-nail man) age 65. I think age is a big factor; but all agree - you HAVE to do the exercises as prescribed. After the 6 weeks when everything is healed, and they say it's time to push it - do it. I don't want to scare you; but it will hurt. My friend Roy who is a rugged gold prospector and can take anything, said it was the hardest thing he's ever done. But he's happy and has full range of motion. My mother cannot lift her arm, her only use is bending it at the elbow - but again, she was a trauma case. My female friend has about 50% usage, but has trouble when she over does it.
I wish you all the best, and hope you have a speedy recovery.
