Suggest Treatment For Staph While Having Cage In Spine After Back Surgery

I had back surgery 3 months back and developed an infection. I had a wound pack for over 30 days. Then the infection was gone. 2 weeks later I started having fever and went back to hospital. I developed staph they said and operated on me and removed the hardware from my fusion. I am bed ridden in hospital and now they tell me they removed the hardware but I have a cage in my spine and it is plastic and they did not remove. They say the infection is on the cage. They were going to wait 2 weeks and put the hardware back in but now who knows. The doctor says I might have to take antibodies the rest of my life. I am in fear of getting A Plastica anemia . I had surgery 1 and half years ago on my back and they put hardware in, which my new doctor now removed and my question is could I have gotten a staph a year and half ago and it remained dormaint? I did have a very high fever then
