Short summary
Fracture-related infections (FRIs) and periprosthetic joint infections (PJIs) fail to recover pathogens, posing a diagnostic challenge and impacting treatment. This new method involves homogenising biopsies with beads to release bacteria, followed by inoculation in blood culture bottles using an automated system. This technique shows similar sensitivity to conventional methods, with improved specificity and faster pathogen detection. To date, no other studies have reported an optimized method for incubating biopsies from patients with FRIs.
