Overview of abrasions

Abrasions are caused by friction, shear and force, causing trauma to the skin. Abrasions are usually partial thickness; these heal by regeneration. Scarring may occur if the injury extends deeper into the dermis. Abrasions commonly follow a fall from a bike or skateboard; the body moves across the ground, compromising skin integrity (see Example of an abrasion).

Abrasions are common injuries in active children and adults. They typically occur on the extremities and exposed skin. Skin loses some of its elasticity, strength and hydration over time, which can predispose older adults to injury.
