Trauma-Related Infections: Prevention, Diagnosis, and Management Strategies







Trauma-Related Infections: Prevention, Diagnosis, and Management Strategies

Вступ

Infections following orthopedic trauma represent some of the most challenging complications faced by surgeons and patients alike. These infections can transform an otherwise recoverable injury into a prolonged, debilitating condition with significant functional limitations and psychological impact. The consequences of trauma-related infections extend beyond the immediate clinical challenges, affecting healthcare systems through increased resource utilization, prolonged hospital stays, and substantial economic burden. For patients, these infections can lead to additional surgeries, extended antibiotic therapy, potential limb loss, and diminished quality of life.

The management of trauma-related infections has evolved significantly over recent decades, driven by advances in our understanding of microbiology, biofilm formation, host-pathogen interactions, and the development of sophisticated diagnostic and treatment modalities. What was once approached primarily through aggressive debridement and prolonged antibiotic therapy has transformed into a nuanced field with infection-specific protocols, targeted antimicrobial strategies, and innovative local delivery systems. This evolution has improved outcomes for many patients, though significant challenges remain in the prevention, diagnosis, and treatment of these complex infections.

The spectrum of trauma-related infections ranges from superficial surgical site infections to deep, implant-associated infections and chronic osteomyelitis. Each presents unique challenges in diagnosis and management, requiring a tailored approach based on infection type, causative organisms, host factors, and the presence of orthopedic implants. The growing prevalence of antimicrobial resistance further complicates treatment, necessitating judicious antibiotic use and innovative approaches to infection control.

This comprehensive review examines the current concepts and advanced techniques in the prevention, diagnosis, and management of trauma-related infections. By understanding both the established principles and emerging approaches in this field, surgeons can optimize outcomes for patients with these challenging complications, balancing the goals of infection eradication, fracture healing, functional recovery, and antimicrobial stewardship.

Висновок

Trauma-related infections represent a significant challenge in orthopedic surgery, with substantial impact on patient outcomes, healthcare resources, and quality of life. The management of these complex infections has evolved significantly over recent decades, driven by advances in our understanding of microbiology, host-pathogen interactions, biofilm formation, and the development of sophisticated diagnostic and treatment modalities. Despite these advances, trauma-related infections continue to present formidable challenges, particularly in the context of increasing antimicrobial resistance and complex host factors.

The prevention of trauma-related infections remains paramount, with evidence-based strategies spanning the preoperative, intraoperative, and postoperative periods. Systematic approaches to patient optimization, surgical technique, antibiotic prophylaxis, and wound management collectively reduce infection risk. For open fractures, timely administration of antibiotics, thorough debridement, appropriate soft tissue management, and fracture stabilization form the cornerstone of infection prevention. The emergence of novel technologies, including antimicrobial surface modifications, local delivery systems, and biofilm prevention strategies, offers promising avenues for further reducing infection rates.

When infections occur, accurate and timely diagnosis is essential for effective management. The integration of clinical assessment, laboratory biomarkers, microbiological sampling, and advanced imaging modalities within standardized diagnostic algorithms enhances diagnostic accuracy. The recent consensus definition for fracture-related infection represents an important step toward standardization in both clinical practice and research. Continued refinement of diagnostic approaches, particularly for biofilm-associated infections, will further improve early detection and intervention.

Treatment strategies for trauma-related infections must balance infection eradication, fracture healing, functional recovery, and antimicrobial stewardship. Surgical management, including appropriate debridement, implant management, dead space treatment, and soft tissue coverage, forms the foundation of successful treatment. Antimicrobial therapy must be tailored to the causative organisms, host factors, and the presence of biofilm, with increasing emphasis on biofilm-active antibiotics and optimized delivery strategies. Local antibiotic delivery systems provide high local concentrations while minimizing systemic toxicity, with evolving technologies offering improved elution characteristics and biodegradability.

Looking forward, the future of trauma-related infection management lies in technological innovation, personalized approaches, and collaborative research. Advanced diagnostics, novel antimicrobial strategies, regenerative medicine integration, and precision treatment based on host and pathogen factors promise to further improve outcomes. Addressing the challenges of antimicrobial resistance through stewardship, alternative approaches, and prevention strategies remains a critical priority. Most importantly, the continued focus on patient-centered outcomes and quality of life will ensure that treatment strategies align with individual patient goals and expectations.

In conclusion, the management of trauma-related infections represents a dynamic field that continues to evolve through scientific discovery, technological innovation, and clinical research. By combining these advances with sound surgical principles, antimicrobial stewardship, and individualized patient care, surgeons can optimize outcomes for patients with these challenging complications, reducing morbidity and improving quality of life.
