Background: Debridement, antibiotics, and implant retention (DAIR) is an established treatment for early periprosthetic joint infection (PJI) following hip arthroplasty; however, reported success rates remain highly variable, particularly in patients with significant comorbidities, fracture-related arthroplasty, or resistant microorganisms. Augmentation of standard DAIR with structured local antimicrobial strategies may improve infection control but remains insufficiently standardized and evaluated. Methods: This retrospective single-center case series evaluated outcomes of a standardized multimodal DAIR-based strategy, the Mursa protocol, in 16 consecutive patients treated for early hip PJI between 2022 and 2025. PJI was diagnosed according to European Bone and Joint Infection Society criteria. The treatment included radical surgical debridement and exchange of mobile components with sequential intraoperative antiseptic microdebridement using povidone–iodine and hypochlorous/hypochlorite solution, followed by postoperative drain-based local antimicrobial irrigation and systemic antibiotic therapy. Treatment success was defined as sustained infection eradication with implant retention, absence of clinical and radiological signs of infection, no requirement for long-term suppressive antibiotics, and no infection-related mortality at a minimum one-year follow-up. Results: The cohort was clinically complex, with a predominance of arthroplasty procedures performed for fracture-related indications (11/16), a high comorbidity burden (median Charlson Comorbidity Index 5), revision arthroplasty in four patients, and a high rate of resistant or polymicrobial infections. At final follow-up, 15 of 16 patients (93.8%) achieved treatment success. One patient required implant removal due to persistent polymicrobial infection. No irrigation-related complications, wound-healing problems, or clinically relevant systemic toxicity were observed. Conclusions: In this high-risk cohort, a structured multimodal DAIR protocol incorporating sequential antiseptic microdebridement and postoperative local antimicrobial irrigation was feasible, safe, and associated with encouraging infection control. However, these findings should be interpreted as hypothesis-generating, and further prospective comparative studies are required to validate the protocol.

Background and Objectives: Simultaneous bilateral scapular fractures are exceptionally rare injuries and are most commonly associated with high-energy trauma, convulsions, or electrical injury. Their occurrence following low-energy trauma is extremely uncommon. This study aimed to conduct a scoping review of the literature on simultaneous bilateral scapular fractures, with emphasis on demographic characteristics, mechanisms of injury, fracture patterns, treatment strategies, and clinical outcomes. To provide clinical context, the findings are illustrated by a case of a 43-year-old previously healthy recreational athlete who sustained simultaneous bilateral scapular fractures after a low-energy fall directly onto the back. Materials and Methods: A scoping review of the literature was conducted in accordance with PRISMA-ScR guidelines using the PubMed/MEDLINE and Scopus databases. Studies reporting simultaneous bilateral scapular fractures were identified and analyzed with respect to demographic characteristics, mechanisms of injury, fracture patterns, treatment modalities, and outcomes. Results: Thirty-seven studies published between 1946 and 2025 were included, comprising a total of 43 patients. Most cases resulted from high-energy trauma (41.9%), convulsions (25.6%), or electrical injury (16.3%). Low-energy trauma and spontaneous fractures were rare. The scapular body was the most commonly involved anatomical region. Conservative treatment predominated and was generally associated with favorable functional outcomes, while surgical intervention was reserved for displaced or intra-articular fractures. The illustrative case involved bilateral comminuted extra-articular fractures of the scapular bodies and spines without associated injuries and was managed conservatively, resulting in complete fracture healing and full, painless shoulder range of motion. Conclusions: The findings of this scoping review, illustrated by the representative clinical case, indicate that simultaneous bilateral scapular fractures may occur even after low-energy trauma in otherwise healthy individuals. Bilaterality alone should not be interpreted as an independent indication for surgical treatment when fractures are stable and minimally displaced. A high index of clinical suspicion and appropriate radiological evaluation are therefore warranted, particularly in emergency and trauma settings, in order to avoid missed or delayed diagnosis, even in cases with seemingly benign mechanisms of injury.

Acute hyperglycaemia is a common COVID-19 complication linked to adverse outcomes. The combined prognostic value of cytokine activation and acute insulin resistance in non-diabetic patients remains unclear. In this prospective cohort study, we enrolled 144 hospitalised adults with RT-PCR-confirmed SARS-CoV-2 infection and no prior diabetes. We aimed to characterise metabolic–inflammatory phenotypes and evaluate their association with disease severity and post-discharge glycaemic outcomes. Patients were classified as normoglycaemic or dysglycaemic based on repeated glucose profiles. Dysglycaemic patients were further phenotyped as stress hyperglycaemia (SHG) or newly diagnosed diabetes (NOD). This classification was based on post-discharge glycaemic assessment at 3 and 6 months, distinguishing transient from persistent hyperglycaemia. Admission hyperglycaemia was associated with a consistently elevated pro-inflammatory cytokine pattern. However, cytokine concentrations were comparable between stress hyperglycaemia and newly diagnosed diabetes, indicating that inflammatory burden alone does not explain metabolic persistence. In contrast, insulin resistance (HOMA-IR) was markedly higher in the newly diagnosed diabetes phenotype. Along with admission oxygenation and key cytokine signals, this contributed to risk stratification for severe disease. In conclusion, early admission assessment of glucose and insulin resistance identifies high-risk metabolic phenotypes. This enables targeted in-hospital risk stratification and post-discharge glycaemic surveillance.
