Gustilo Classification

  • Type I: open fracture with skin wound <1cm in length and clean
  • Type II: open fracture with a wound >1cm in length without extensive soft tissue damage, flaps, or avulsions
  • Type III: open segmental fracture with a wound >10cm in length with extensive soft tissue injury or a traumatic amputation
    • IIIA: adequate soft tissue coverage
      • All farm injuries and gunshots are automatically at least IIIA
    • IIIB: significant soft tissue loss with exposed bone that requires soft tissue transfer to achieve coverage
    • IIIC: associated vascular injury that requires repair for limb preservation
    • Special categories:
      • gunshot injuries
      • any open fracture caused by a farm injury
      • any open fracture with accompanying vascular injury requiring repair

Risk of Infection

  • Type I: 0%
  • Type II: 2%
  • Type III: 6-44%
    • Type IIIA: 2%
    • Type IIIB: 11%
    • Type IIIC: 20%

Management

  • Don't forget tetanus!
  • Antibiotic choice
    • Cover Gram-positives as soon as possible after injury, e.g. with cefazolin
    • Add Gram-negative coverage for type III fractures, e.g. with tobramycin
    • Consider adding anaerobic coverage
    • For example, one Ontario trauma center uses cefazolin, tobramycin, and metronidazole
    • Add high-dose penicillin to cover Clostridium, in the presence of fecal contamination or farm-related injuries
    • Fluoroquinolones should be avoided, if possible, due to slowing bone healing
  • Duration
    • Continue for 24 hours after wound closure
    • If type III, continue for at least 72 hours post-injury if Type III
