According to the Wagner classification of the diabetic foot, gangrene localised to the forefoot corresponds to which grade?
- A Grade 2
- B Grade 3
- C Grade 4 ✓
- D Grade 5
Correct answer: C. Grade 4
Explanation
The Wagner grading runs from grade 0, a pre-ulcerative or healed lesion, through grade 1, a superficial ulcer, grade 2, an ulcer extending to tendon or capsule, grade 3, an ulcer with abscess, osteomyelitis or joint sepsis, to grade 4, gangrene limited to the forefoot or toes, and grade 5, gangrene of the entire foot. Grade 3 is often confused with grade 4, but grade 3 describes infection complicating an ulcer rather than established tissue death.
