How is a puncture wound typically created?

A puncture wound is created when a sharp object delivers a stab that penetrates the skin but does not necessarily cut through it completely. This type of wound is characterized by a small opening and can be deeper than it appears on the surface. Sharp objects such as nails, needles, or even animal bites can cause puncture wounds.

The mechanism of injury involves the object penetrating the skin rather than tearing it, which differentiates it from other types of wounds. While blunt objects may cause contusions or abrasions, they do not create the narrow, distinct opening associated with puncture wounds. Similarly, a tear in the skin would indicate a laceration, and friction against a rough surface would typically result in abrasions or scrapes, not punctures. Therefore, the key aspect of a puncture wound is the action of a sharp object delivering a piercing force.
