My active sister broke her hip 2mo ago. she had hip replacement, infection, replacement of artif hip with spacer, then removal of spacer. what next?

Revision surgery: She will require antibiotics for at least six weeks, followed by a second hip replacement surgery called a revision.

Replace joint: Two stage replacement of the joint after infection is the accepted and safe practice if the patient is free from infection. Attention, care, and time are the tools for thorough evaluation prior to placement of the second prosthesis.

Revision THA: Once the infection is eradicated, a new hip should be placed.

Try to do again: Minimum of six weeks of IV antibiotic therapy. Once off antibiotics, blood tests to look for signs of infection returning. If incision and bloodwork good then attempt to put another hip repalcement back in. Cultures at time of surgery and tests during surgery possibly may show continued infection and ultimate replacement may need to be delayed further until all signs of infection are gone.
