Definitions:

Bony Prominence

Areas of the body where bone is close to the skin, which are at higher risk for pressure sores.

Pressure Ulcers

Injuries to skin and underlying tissues, usually over a bony prominence, as a result of prolonged pressure or friction.

Shear And Friction

Shear refers to a force that causes layers of tissue to slide against each other, while friction is the resistance that one surface encounters when moving over another, both of which can contribute to skin injury.

Stage 3 Pressure Ulcer

A pressure injury that involves full-thickness skin loss, potentially extending into the subcutaneous tissue, without exposure of muscle or bone.
