We looked at whether routine blood tests could help identify patients at higher risk of infection after hip fracture surgery. Using data from a large group of older patients, we found that higher inflammation levels after surgery, especially when they increased compared to before surgery, were linked to a greater risk of infection. This suggests that simple and widely available tests may help clinicians recognize high-risk patients earlier and guide closer follow-up.

Fungal infection can be difficult to treat, requiring long periods of hospitalisation. Rezafungin is a promising new antifungal medication that can be used to treat complex, deep-seated fungal infection. We examine the reported use of rezafungin in managing fungal infection of the bones and joints in an outpatient setting. Our case helps to provide further experience in the use of rezafungin as a powerful tool in helping patients get out of hospital and avoid further admissions.

Fracture-related infection is a serious problem after broken bones, especially in low-resource settings where specialist care and services are limited. An international expert group developed practical recommendations adapted to these realities. The guidance focuses on early fracture care, simple diagnostic approaches, flexible antibiotic use, affordable local treatments, good soft tissue management, and teamwork, aiming to improve safe and effective care in resource-limited environments.

Culture-negative periprosthetic joint infection (CN-PJI) remains a diagnostic and therapeutic challenge. In this systematic review and meta-analysis of 27 studies (1399 patients), pooled success was 83.6 %, failure was 17.2 %, and mortality was 2.4 %. Outcomes were better with exchange arthroplasty than debridement, antimicrobials, and implant retention (DAIR). Antibiotic regimens were heterogeneous. Overall, CN-PJI may have favorable outcomes, but standardized prospective studies are needed.

This study explores the diagnostic value of sonication fluid culture (SFC) as an adjunct to conventional diagnostic methods for fracture-related infection (FRI). SFC improves pathogen detection and contributes to more accurate diagnosis of FRI. In approximately 6 % to 16 % of confirmed FRI cases, SFC influenced FRI management. These findings support the routine use of SFC alongside standard tissue cultures, with adequate sampling according to protocol.

Prosthetic joint infections are devastating complications of joint replacements, often resisting antibiotics because bacteria hide inside a protective slime called biofilm. We reviewed laboratory evidence on BromAc, a combination of a pineapple enzyme and a mucus-thinning agent that breaks down this slime. Early experiments suggest it can disrupt biofilm and improve antibiotic access, but key questions about safety, stability, and joint-specific testing must be answered before patient use.

Joint replacement infections are difficult to diagnose quickly because standard laboratory cultures can take days to weeks and may miss bacteria after antibiotic treatment. We evaluated a rapid molecular test using fluid from removed implants and found that it provided clinically useful results within hours. This approach may help doctors exclude infection sooner, reduce unnecessary antibiotic use, and improve patient care.

We studied patients with infected hip replacements to determine whether delays between hospital admission and  surgery affected recovery. By reviewing patient records from a specialty center, we found that longer delays were linked to a higher risk of death within 90 d. Older age, poorer overall health, and low blood levels also increased the chance of complications or repeat surgery. These results suggest that prompt treatment and careful health preparation can improve outcomes. 

The current umbrella review showed that prevalence, diagnostic performance of adjunctive molecular methods, treatment strategies, and outcomes vary substantially. Molecular diagnostics appear to be promising as adjunctive tools in selected cases, but their interpretation requires caution, and they do not resolve all uncertainties related to culture-negative periprosthetic joint infections. 

We examined whether patients with musculoskeletal infections need to be separated in hospital. A review of published studies found no support for routine isolation or dedicated wards for infections without multidrug-resistant organisms when standard precautions are applied. An international survey showed wide variation in clinician attitudes. These findings highlight a gap between evidence and perception and support a more risk-based approach.

Bacterial infections on orthopedic implants are difficult to treat because bacteria form protective biofilms. We tested antiseptic solutions against Staphylococcus aureus biofilms on stainless steel. Povidone-iodine achieved the greatest reduction, exceeding 99.9% bacterial killing. Dilute povidone-iodine performed as well as full-strength, important since lower concentrations reduce tissue toxicity. Hypochlorous acid and chlorhexidine showed lower activity, while saline was minimally effective.
