Physiology-Guided Surgical Strategies and Functional Outcomes in Severe Musculoskeletal Trauma

Advanced musculoskeletal trauma represents a major global health challenge, particularly in polytrauma patients where surgical timing, fixation strategy, complication prevention, and long-term recovery are closely interconnected. This review analyzes contemporary evidence regarding damage control orthopedics, early total care, fixation techniques in complex fractures, fracture-related infection, nonunion, and functional recovery outcomes. Current literature supports a physiology-guided approach to surgical timing, emphasizing individualized decision-making based on hemodynamic stability, systemic inflammatory response, and institutional capacity rather than rigid temporal thresholds. Comparative evidence on fixation methods suggests that biomechanical stability must be aligned with biological preservation to optimize healing. Infection and nonunion remain principal determinants of long-term disability, reinforcing the importance of early debridement, appropriate antibiotic use, and soft tissue management. Importantly, functional recovery and health-related quality of life have emerged as primary outcome measures, demonstrating that radiographic union alone does not guarantee meaningful recovery. Limb salvage versus amputation decisions, in particular, require careful consideration of long-term function and patient-centered goals. These findings are especially relevant for trauma systems in middle-income countries, including Mexico, Colombia, and Ecuador, where resource variability may influence the translation of international guidelines into practice. Advanced musculoskeletal trauma care therefore requires dynamic clinical reasoning, multidisciplinary coordination, and outcome-oriented strategies that integrate physiology, biomechanics, and rehabilitation into a cohesive model of recovery.
