Abstract
Only a few cases of infection of an endoprosthesis with mycobacterium fortuitum have been reported, each resulting in functionally unsatisfactory outcomes. We performed a stem revision cementless total hip endoprosthesis six months after primary implantation after the appearance of the typical radiological and clinical signs of aseptic loosening.
Histological and molecular-biological analysis of the intra-operative specimens confirmed an infection with Mycobacterium fortuitum.
Following antimicrobial therapy, the patient is painfree and fully weight-bearing seven months after replacement.
If aseptic loosening of an endoprosthesis is suspected, an infection with Mycobacterium fortuitum should be considered.
