Fracture-Related Infection of the Proximal Femur - Diagnostics and Treatment.

Abstract

Purpose: With the aging population and rising life expectancy the incidence of trauma-related injuries, particularly proximal femur fractures, is expected to increase. Complications such as fracture-related infections (FRI) significantly impede the healing process and pose substantial risks to patients. Despite advancements in understanding, diagnosing, and treating FRI, challenges persist in achieving optimal outcomes. This review addresses the significance of FRI following proximal femur fractures, emphasizing diagnostic methodologies and therapeutic modalities to enhance clinical care.

Findings: Notably, a consensus definition for FRI has been established, providing clarity for accurate diagnosis. Diagnostic criteria encompass confirmatory and suggestive elements, facilitating precise identification of FRI. Therapeutic strategies for FRI in proximal femur fractures include a spectrum of surgical and antimicrobial approaches. Surgical interventions, ranging from debridement with implant retention over implant removal/exchange to staged conversions to arthroplasty, are tailored based on fracture stability, individual patient factors, and infection characteristics. The intricate decision-making process is elucidated, highlighting the importance of individualized treatment plans and multidisciplinary collaboration. Antimicrobial therapy plays a pivotal role in FRI management, with empirical regiments targeting common pathogens and local delivery systems offering sustained antibiotic release. Microbiological analysis and collaboration with infectious disease specialists should guide antimicrobial treatment and ensure optimal therapy efficacy.

Conclusion: Managing FRI following proximal femur fractures requires a tailored, multidisciplinary approach. Treatment strategies should be guided by diagnostic precision, patient-specific considerations, and collaboration among surgical, infectious disease, and clinical teams. Implementing comprehensive therapeutic approaches is essential for mitigating the impact of FRI and improving patient outcomes.
