Hi Doctor, I have had multiple surgeries in the last 4 years. I fell at work going down stairs. I had a rrt shoulder arthroscopy & debridmement, A failed L/S fusion (anterior approach) it was supposed to be 1 surgery but due to complications the second part (insertion of hardware) was postponed. I then had a ivc filer inserted due to DVT. Then I had A tkr LT. Now I am told I require a C?S fusion, A NEW l/s fusion, A lt knee revision & a tkr RT. What is wrong with me ?
