53 also - just had rotator repaired - as well as labrum cleaned up and bicep tendonesis (or whatever it is called - they move bicep tendon down so it isn't pulling on joint) - and you are scaring hell outta me because I want to keep exercising - getting old sucks. Tall, long-limbed Oline guys with that many shoulder issues that young - likely to be a tough thing to over-come for Woletzko I think - is cruddy when joints just not build like the "Larry Allen" or "Mazi" style titanium....
You can still work out. My second tare was fluke. 2 movements will reinjure it. A heavy weighted backhand or forehand sudden movement like tennis backhand or forehand stroke. I had a heavy tree limb and grabbed it and tried to throw it up on a pile. Wrong angle. The other is grabbing something heavy up high and don’t realize how heavy it is and the sudden pull downward. Like some one in the back of a truck handing you a heavy suitcase or something and your standing on the ground and reach up and grab it and they let it go and the sudden weight pulling downward.
Last tare happened when I was sitting in an inflaitable chair about 4 months after the surgery and it flipped over backwards. I put my hand out to stop the fall. Couldn’t pick my arm up for 3 days. I literally cried because I knew what happened. You will be fine. Stay light with lots of reps.
Sounds like you did a doozy on your. Mine was similar. Bicep tendon was out of the groove it’s supposed to be in. Grade 2 AC seperation.
