Open fractures: the BOAST standard, timings and the Gustilo–Anderson classification

The BOAST open fracture standard for FRCS (Tr & Orth): antibiotics within an hour, debridement at 12 or 24 hours, cover within 72 hours, and Gustilo–Anderson grading.

  • Intravenous prophylactic antibiotics are given as soon as possible, ideally within one hour of injury.
  • Debridement is immediate for highly contaminated wounds and for vascular compromise, within 12 hours for solitary high-energy open fractures, and within 24 hours for low-energy open fractures.
  • Definitive soft-tissue closure or cover is achieved within 72 hours of injury if it cannot be done at the time of debridement, and definitive internal fixation is performed only when it can be followed immediately by definitive cover.
