My mother has just been told she needs a reverse shoulder replacement. She has bilateral frozen shoulders from 20+ years of carrying mail and was struck by a car in an auto vs pedestrian accident which fractured her proximal humerus. She was recently told that her right glenoid has been worn down so severely that soon there will not be enough bone to even perform the reverse shoulder replacement. I'd like to speak about the potential for stem cell therapy in my mother's case.
