I have seen some posts related to biofilm infections. I would like more information since I have one. New orthopedic surgeon immediately diagnosed me with loose hip stem. Planned surgery to revise and replace. But he was able to pull out old hip stem with his hand and it was covered with slime. He put in spacers. Currently on IV antibiotics - invanz and daptomycin. Ceftriaxone did not work and was switched to invanz. Seems this new combo is working. This is my fourth surgery on right hip. My hip stem loosened after the previous three. Glad this doc figured it out, but bummed I'm still a work in progress.
