Which stage is associated with exposure of bone, tendon, or muscle?

• A. Stage 2
• B. Stage 3
• C. Stage 4
• D. Stage 1

Answer: (C)

Exposure of bone, tendon, or muscle signals full-thickness tissue loss that reaches deep structures. In this stage the wound goes through the dermis and subcutaneous tissue and may show bone, tendon, or muscle as visible or directly palpable. This distinguishes it from earlier stages: partial-thickness loss is limited to skin layers without deep tissue exposure, and earlier full-thickness loss does not yet expose bone, tendon, or muscle. Recognizing this level of depth is crucial because it indicates a more severe injury that requires more intensive wound management and evaluation for complications.
