What skin injury results from a sharp object creating a small hole?

A puncture is a type of skin injury that occurs when a sharp object penetrates the skin, creating a small hole. This injury typically happens when an object such as a nail, a toothpick, or a needle is pushed into the skin. Unlike other injuries, a puncture wound is characterized by its depth compared to its size, as it may not bleed significantly but can still introduce bacteria and other pathogens deep into the tissue, leading to a risk of infection.

In contrast, an incision is usually longer and deeper due to a sharp object cutting through the skin. An avulsion involves the tearing away of tissue, often resulting in a flap of skin that is partially or completely detached. An abrasion occurs when the top layer of skin is scraped off, often from friction against a rough surface. Understanding these distinctions is crucial as they have different implications for treatment and healing.
