Infection of orthopedic prostheses after Staphylococcus aureus bacteremia

We prospectively evaluated 53 patients with prosthetic joints and 27 patients with other orthopedic prosthetic devices who developed Staphylococcus aureus bacteremia (SAB). After exclusion of patients with primary postoperative infections, the risk of a prosthesis becoming infected by means of hematogenous seeding after SAB was 34% (15 of 44 patients) for prosthetic joints and 7% (1 of 15 patients) for other orthopedic prostheses.
