Management of Fracture-Related Infections
Surgical Management
- The American College of Surgeons recommends serial debridement with hardware removal as the cornerstone of treating fracture-related infection (FRI) 1, 2
- Successful cure of FRI requires not only surgical debridement and fracture consolidation, but also soft tissue management including reconstruction and revascularization 1
- Optimal definitive soft tissue coverage should be achieved as soon as possible, not only for prevention but also for treatment of FRI 1, 2
- The use of free flaps provides a robust antimicrobial barrier, prevents further contamination, creates a biological environment conducive to fracture healing, and improves antibiotic delivery through enhanced vascularization 1
Antibiotic Regimen
- The Infectious Diseases Society of America recommends cefepime for potential Pseudomonas aeruginosa and gram-negative coverage in complex wound infections 4
- Cefepime provides appropriate coverage for the polymicrobial nature of type III open fractures with environmental contamination 1, 2
- Metronidazole is essential for anaerobic coverage, specifically targeting Bacteroides species identified in this patient's infection 4, 5
- The World Health Organization recommends metronidazole for Bacteroides infections in skin and soft tissue infections 4, 5
- Cefepime provides reasonable coverage for Aeromonas species, though fluoroquinolone addition could be considered if clinical response is inadequate 4
Treatment Duration
- The International Society for Fracture Repair recommends 6 weeks of antimicrobial therapy after implant removal in fracture-related infections 1, 2, 3
- IV therapy should be limited to 1-2 weeks until the patient is stable and culture results are known, based on the OVIVA trial showing non-inferiority of oral antibiotics 1, 2
