The hip joint is pretty isolated from the rest of the body I assume, I had the same question for my surgeon and he told me there was no way for that to happen.

Aren’t there any antibacterial sprays or devices they can leave behind? What if antibodies were extracted from the patient’s blood before surgery then sprayed on at the end of the operation?

You wash, irrigate, and provide prophylactic antibiotics but shit happens, this was a very unfortunate case especially as there was no implant.

Pseudomonas infections are rare in healthy patients and few antibiotics work.

any part of your body - besides hair, nails and bones, I suppose - need to be supplied with nutrients, water, etc

Bones are live tissue and are constantly being remodeled. About a tenth of the heart's output flows into the bones.

okay not bones then, but it makes my question stronger

how can you have a bacterial infection in your hip that doesn’t make it to the rest of your body?
