What are the recommendations for open fracture management according to the GOLIATH study?

GOLIATH Study Summary

I cannot provide a summary of the GOLIATH study as it is not included in the evidence provided. The evidence contains AAOS guidelines and other research on open fracture management, but no study specifically titled or referenced as "GOLIATH."

What the Evidence Does Show: Current Open Fracture Management Recommendations

Initial Antibiotic Administration

Antibiotics should be administered as soon as possible after injury, ideally within 3 hours, as delays beyond this timeframe significantly increase infection risk. 1, 2

• For Gustilo-Anderson Type I and II fractures: Use cefazolin (first-generation cephalosporin) or clindamycin if beta-lactam allergic 3, 1, 2
• For Type III (and possibly Type II) fractures: Add gram-negative coverage with either aminoglycoside or piperacillin-tazobactam 3, 1, 2
• Piperacillin-tazobactam is now preferred as a single agent for Type III fractures, providing comprehensive coverage without requiring aminoglycosides 1
• Continue antibiotics for maximum 48-72 hours post-injury unless infection is proven 2

Surgical Timing

Patients with open fractures should be brought to the operating room for debridement and irrigation ideally within 24 hours of injury, though delays beyond 6 hours do not significantly increase infection rates in children who receive early antibiotics. 3, 2

• The traditional "6-hour rule" has been challenged by multiple studies showing no significant difference in infection rates between surgery within 6 hours versus 7-24 hours, particularly in pediatric populations 4, 5
• In one multicenter study of 554 pediatric open fractures, infection rates were 3% for fractures treated within 6 hours versus 2% for those treated after 7 hours (not statistically significant) 4

Wound Irrigation

Irrigation with normal saline without additives is strongly recommended for open wound management. 3, 2

• Antiseptics or soap additives provide no benefit over simple saline solution 1, 2
• This is a strong recommendation from AAOS guidelines 3

Fracture Fixation Strategy

Definitive fixation at initial debridement with primary closure may be considered in selected patients, though temporizing external fixation remains a viable option. 3, 2

• The choice depends on fracture pattern, soft tissue injury extent, contamination level, and patient factors 2
• For severe injuries with substantial contamination or extensive soft tissue damage, temporary fixation and staged wound closure are preferred 6

Wound Coverage Timing

Soft tissue coverage should be achieved within 7 days from injury date to reduce fracture-related infection risk. 3, 2

• Definitive treatment with soft tissue coverage should ideally occur within 72 hours 6

Local Antibiotic Adjuncts

Local antibiotic delivery systems (vancomycin powder, tobramycin-impregnated beads, gentamicin-covered implants) are beneficial adjuncts, particularly for Type III fractures with bone loss. 1, 2

• These should be considered during definitive surgery 1
• Gentamicin-coated implants have demonstrated safety in clinical application 1

Negative Pressure Wound Therapy

NPWT may be considered for closed fracture fixation to reduce revision surgery or surgical site infection risk, but does not offer advantages over sealed dressings after open fracture fixation. 2

Common Pitfalls to Avoid

• Delaying antibiotic administration beyond 3 hours significantly increases infection risk 1, 2
• Using antiseptics or soap additives for wound irrigation provides no benefit 1
• Failing to consider local antibiotic delivery systems in severe Type III fractures 1
• Assuming all open fractures require surgery within 6 hours—current evidence supports safe surgery within 24 hours when early antibiotics are given 3, 4
