Permanent Bad Shoulders

What are some chest and back exercises that don’t involved shoulders so much?
Doc said if I continued to do shoulders i would have to get shoulder replacement in near future

is the sensible thing to do not to diagnose what is wrong with your shoulders and correct it?

I would if I could but was told that by Dr Bowen (Chicago Bears Doctor)
So if I continued working shoulders then i will probably be in constant pain for the rest of my life with artificial shoulders

The chest and back muscles basically move the arms through the shoulder joint. Can they not take load via any plane?

Doc said Ok to do pullback exercises but go very light on push exercises
No workouts with arms above shoulders
