Antibiotic Prophylaxis in Open Fractures: Evidence, Evolving Issues, and Recommendations

Area of Science:

• Orthopedic Surgery
• Infectious Diseases
• Trauma Care

Background:

• Open fractures result from high-energy trauma, causing soft-tissue damage and introducing contaminants, increasing infection risk.
• The Gustilo-Anderson classification stratifies open fractures, correlating fracture type with surgical site infection (SSI) rates and pathogen profiles.
• Prophylactic antibiotic strategies for open fractures have evolved over decades, incorporating various antibiotic classes.

Purpose of the Study:

• To review the evolution and current landscape of prophylactic antibiotic therapy for open fractures.
• To highlight the role of the Gustilo-Anderson classification in guiding antibiotic selection.
• To identify areas of ongoing research, including antibiotic duration and coverage for resistant organisms.

Main Methods:

• Review of historical and current literature on open fracture management and antibiotic prophylaxis.
• Analysis of the Gustilo-Anderson classification's impact on SSI rates and treatment protocols.
• Discussion of antibiotic classes used, including traditional agents and broader-spectrum options.

Main Results:

• Different open fracture types exhibit varying SSI rates and pathogen susceptibilities.
• Antibiotic prophylaxis has evolved from basic penicillins/cephalosporins to broader agents like monobactams and glycopeptides.
• Significant variability exists in antibiotic choice and duration across institutions.

Conclusions:

• Prophylactic antibiotics are essential for managing open fractures to prevent SSIs.
• Standardization of antibiotic choice and duration remains a challenge in clinical practice.
• Further research is needed to optimize antibiotic regimens, particularly for multidrug-resistant organisms.
