قرحة فوق العجز: فقدان كامل لسماكة الجلد، والدهون تحت الجلد ظاهرة، ولا يظهر عظم ولا وتر ولا عضلة، وفيها نسيج متموّت أصفر قليل لا يغطي قاع الجرح. ما مرحلتها؟

A sacral wound shows full-thickness skin loss with visible subcutaneous fat, no exposed bone, tendon or muscle, and a little yellow slough that does not obscure the wound base. What stage is it?

1. Stage 4
2. Unstageable
3. Stage 3
4. Stage 2

Answer: C) Stage 3. Full-thickness loss with visible fat but no bone, tendon or muscle is stage 3. Stage 2 is partial thickness without visible fat, stage 4 exposes bone, tendon or muscle, and unstageable means slough or eschar hides the whole base.
