In Gustilo-Anderson classification of open fractures, a Type IIIB fracture is specifically characterized by:
- A Extensive soft tissue injury requiring local or free flap for coverage ✓
- B Wound >10 cm with adequate soft tissue coverage
- C Arterial injury requiring repair
- D Gross contamination with wound <1 cm
Explanation
Gustilo Type IIIB involves extensive periosteal stripping and soft tissue injury with inadequate coverage — local or free flap reconstruction is mandatory for wound closure. Type IIIA has adequate soft tissue despite extensive injury. Type IIIC involves arterial injury requiring vascular repair regardless of wound size. Type I is a clean wound <1 cm. Correct sub-classification drives surgical planning including timing of flap coverage.
