Management of Gustillo Type 3 Open Fracture

Wound Management

• The American Academy of Orthopaedic Surgeons (AAOS) guidelines support leaving the wound open until operative repair, as premature closure with staples would trap contamination and increase infection risk 1, 2, 3
• Irrigate the wound immediately with simple saline solution, as soap or antiseptics provide no additional benefit, according to the AAOS guidelines 1, 2, 3

Antibiotic Regimen

• The AAOS recommends starting antibiotics immediately, with a preferred regimen of piperacillin-tazobactam 3.375g IV every 6 hours (or 4.5g every 8 hours for an 80kg patient), which provides both gram-positive and gram-negative coverage in a single agent 1, 2, 3, 4
• For patients with a penicillin allergy, the AAOS recommends clindamycin 900mg IV every 8 hours, plus gentamicin or amikacin, as an alternative regimen 1, 2, 3, 5

Timing to OR

• The AAOS guidelines debunk the traditional "six-hour rule" with moderate strength evidence showing that surgery can safely occur within 24 hours for most open fractures, allowing for better resource allocation with a properly staffed OR 1, 2, 3

Additional Considerations for OR

• The AAOS recommends considering local antibiotic strategies during definitive surgery, such as vancomycin powder, tobramycin-impregnated beads, or gentamicin-covered implants, as adjuncts, particularly useful in Type III fractures with bone loss 1, 2, 3, 4
• Definitive stabilization and primary closure at initial débridement is supported for selected open fractures, though outcomes vary, according to the AAOS guidelines 1, 2, 3

Common Pitfalls to Avoid

• The AAOS guidelines advise against closing the wound before OR, delaying antibiotics, using antiseptic irrigation solutions, continuing antibiotics beyond 72 hours without evidence of infection, and adding vancomycin routinely, as these practices can increase infection risk, resistance, and C. difficile risk 1, 2, 3, 4, 5
