If you do surgery again, see if they can do a bone graft. My husband just had a total shoulder because he was bone on bone, and also where the bones are in the shoulder, the bone was narrow on the curve, and unfortunately he has some really large "cysts" that filled up with synovial fluid, but REPLACED the bone, so had he fallen, he could have crushed it. The surgeon said he was fortunate to do the surgery now, had he waited, and the bone area got less than 50%, they would never be able to do the surgery. When they did the surgery and scraped out the bones, those cysts break open and fluid comes out. So when they cut off that round shoulder joint bone, they used his own bone material, packed in into the "holes" created by the cysts, and they said his own bone will now fill the empty bone areas, and fuse/grow! Maybe something like that would help you. He did his at Mayo Clinic in Rochester.
