A laceration is a wound that is produced by the tearing of soft body tissue. This type of wound is often irregular and jagged. A laceration wound is often contaminated with bacteria and debris from whatever object caused the cut.
A puncture wound is usually caused by a sharp pointy object such as a nail, animal teeth, or a tack. This type of wound usually does not bleed excessively and can appear to close up. Puncture wounds are also prone to infection and should be treated appropriately.
