@martin37350 Oh no, oh no. I was just tortured when I read your post. Let me see if I can wrap my arms and my heart around this unexpected and certainly unwelcome outcome. So....no rotator cuff? Here is a video of a reverse replacement. Does that look familiar to you? Am I understanding the images correctly? I have no rotator cuff.......and yet the ball fits quite well into the socket. My PT and personal trainer worked tirelessly to strengthen the deltoid so that it would be able to lift the shoulder.

What would a second surgery involve? What are the risks? What might the reward be? and then... What is the quality of life improvement your husband can have if he undergoes another surgery....and a recuperation? Essentially I had 2 rotator cuff surgeries that didn't work and then waited another year or so for insurance approval for the reverse.

Have a look at this video and see if the parts of the puzzle are in the right places?
Have you thought of a second opinion with a focus on potential outcomes?

Please hunt me down when you have some info and I will come a-running. Thank you for including me.

May you be free of suffering and the causes of suffering.
