Our study investigated olecranon septic bursitis treatment, focusing on postsurgical antibiotic use. Analyzing 22 years of Mayo Clinic data, we found that smoking and not administering antibiotics following surgery led to poorer outcomes. A 3-week antibiotic course following surgery was most effective. Our findings suggest that a subset of patients may benefit from longer courses of antibiotics; however, further research is needed to confirm these findings. 

We define an algorithm to optimize bone and joint infection diagnosis in adults on synovial fluid samples. This prospective multi-center study included a large number of synovial fluids and compared the performance of classical culture on different media, inoculation of synovial fluid in blood culture bottles, and broad-range and specific PCR. We proposed an algorithm associating culture onto three solid media and into blood culture bottles and 16S, Staphylococcus, and Streptococcus PCR.

We describe 48 osteocutaneous-flap-related osteomyelitis cases, mostly presenting with early, local signs of infection and/or bone exposure. Main pathogens were Gram-negative bacilli, streptococci, S. aureus, enterococci, and anaerobes, justifying a broad-spectrum empirical antimicrobial therapy. Despite surgery and a 3-month antimicrobial therapy, a 50 % failure rate was recorded, associated with a delayed infectious disease specialist referral and advocating for multidisciplinary management.

Costs related to off-label expensive antibiotics used to treat bone and joint infections (BJIs) in a referral centre in France were analysed in this cohort study. Despite the large increase in the number of patients treated with these antibiotics, the overall costs remained stable (approximately EUR 1 million) and were helped by the appearance of generic molecules at lower prices. Production of generic antibiotics at low cost is essential to limit the financial burden of the management of BJIs.
