What is the defining characteristic of a full-thickness wound?

A full-thickness wound is characterized by the involvement of all layers of the skin, including the epidermis, dermis, and subcutaneous tissue. This type of wound extends through the full depth of the skin, which can result in a significant loss of tissue, and may also expose underlying structures, such as muscles, tendons, or bone.

Recognizing that full-thickness wounds penetrate deeply helps healthcare providers develop appropriate treatment strategies, as these wounds often require more advanced interventions, including surgical debridement, wound dressings that support healing, and potential grafting depending on the area and extent of the injury.

In contrast, wounds that involve only the epidermis, dermis, or superficial layers of skin do not reach the deeper tissues and typically follow different healing pathways. Understanding the specific nature of a full-thickness wound is crucial for effective management and care.
