Open Fractures

Classification, antibiotics, timing, and soft-tissue principles.

At a glance

An open fracture is a fracture that communicates with the outside world. Soft-tissue injury, contamination, and neurovascular status drive urgency more than the bone pattern alone.

Early antibiotics, tetanus care, and a clear plan for debridement and coverage matter as much as the implant. Gustilo–Anderson remains the shared language for communication and exams — use it carefully, knowing real-world grading is imperfect.

Classification

Gustilo–Anderson (clinical communication language):

  • Type I — clean wound <1 cm
  • Type II — wound >1 cm without extensive soft-tissue damage
  • Type IIIA — extensive soft-tissue laceration, adequate coverage still possible
  • Type IIIB — extensive soft-tissue loss requiring flap coverage
  • Type IIIC — arterial injury requiring repair

Grading can change after debridement. Document what you see and what plastics / vascular may need to own.

Decision-making

Ask, in order: 1. Is the limb threatened (vascular, compartment, crush)? 2. Have antibiotics and tetanus been given? 3. What is the realistic soft-tissue envelope after washout? 4. Who owns coverage if the wound will not close primarily? 5. Is this damage-control (span / temporary) or definitive tonight?

Fixation choice follows soft-tissue reality more than fracture personality. A perfect articular reduction under a dead flap is a failure.

Treatment

  • Antibiotics ASAP — typically a first-generation cephalosporin; add Gram-negative coverage for Type III / farm / water injuries per institutional protocol
  • Urgent operative irrigation and debridement; repeat as needed
  • Stabilize bone to protect soft tissue (external fixation often first in high-energy injuries)
  • Soft-tissue coverage as early as the wound and team allow
  • Serial neurovascular and compartment exams

High-yield / exam

  • Antibiotics as soon as possible after recognition
  • Gustilo classification is still the exam language
  • Type III injuries need early ortho + plastics thinking
  • Tetanus status is part of the initial order set
  • IIIC = arterial injury requiring repair
