Abstract (original English)

Polytrauma with predominant musculoskeletal (MSK) injury, resulting from blast, blunt, and crush mechanisms, remains a leading and complex challenge in both military and civilian medicine. These injuries not only disrupt tissues structurally but also trigger systemic cascades involving immune imbalance, endothelial dysfunction, mitochondrial stress, and premature cellular senescence. Such pathological processes contribute to both immediate clinical instability and long-term complications such as fibrosis, aberrant bone formation, neuroinflammation, and chronic disability. Conventional injury assessments, which rely heavily on anatomical scoring and nonspecific blood markers, fail to capture the dynamic molecular landscape underlying these conditions. To address this critical gap, we performed a comprehensive scoping review integrating evidence from basic science, translational studies, and clinical research published between January 2000 to June 2025, with particular emphasis on recent advances. The review highlights the discovery and validation of emerging blood-based and molecular biomarkers, including fatty acid-binding protein 3, syndecan-1, galectin-3, and trauma-associated microRNAs, as well as innovative diagnostic paradigms such as wearable biosensors, minimally invasive liquid biopsy platforms, and artificial intelligence (AI)-driven analytics. Unlike prior reviews, ou
