The AO/OTA classification grades open fractures based on periosteal stripping, bone vascularity, and contamination. Which Gustilo–Anderson grade specifically requires vascular repair for limb viability?
- A Grade IIIC ✓
- B Grade II
- C Grade IIIA
- D Grade IIIB
Correct answer: A. Grade IIIC
Explanation
Gustilo–Anderson Grade IIIC is defined by arterial injury requiring repair regardless of soft-tissue damage extent; without vascular repair, the limb cannot survive. Grade IIIA has adequate soft-tissue coverage despite extensive injury; Grade IIIB has massive soft-tissue loss requiring flap coverage; Grade II has moderate soft-tissue damage without arterial injury. The IIIC designation specifically drives vascular surgery involvement and amputation-versus-salvage decision-making.
