Infected prosthesis and implant treatment with acoustic pressure shock waves

A method comprising determining a type of infection caused by either planktonic bacteria pathogens or biofilm at an infected interface of bone and a prosthesis or an implant fixed to the bone in a human or animal body and applying extracorporeal acoustic pressure shock waves to the infected interface of the bone and the prosthesis or implant in a sufficient amount, based on whether the infection is caused by planktonic bacteria or biofilm, to at least one of disrupt the biofilm and kill the planktonic bacteria pathogens at the infected interface of the bone and the prosthesis or implant.
