Thank you so much for your reply. At this point I am doing physical therapy to try to build up the muscles in my shoulder. Of the four rotator cuff‘s two are completely severed and one is partially severed. The Achilles tendons from the cadaver are going to be placed over the top of my shoulder connecting near my collarbone. I have had rotator cuff surgery with pins in both shoulders prior to this and have a pretty good understanding of rehab and recovery. I will get to that stage after six weeks with my arm in a brace. Your suggestions are very thoughtful and I certainly am trying now to use my left arm as much as possible to get it trained. Thankfully, I have a husband who is a 15 on a scale of 1 to 10. He will take very good care of me and we have adult children and grandchildren nearby to help also. Any suggestions are always appreciated. Take care. Sally from Oregon.
