A puncture wound is a narrow, deep wound caused by a pointed object penetrating the skin. Synonyms for puncture wound include stab wound, penetration wound, perforation, penetration injury, needle stick injury, and penetrating trauma. These injuries are common in accidents involving sharp objects, such as needles, knives, and nails. Puncture wounds can be severe and can lead to infection, especially if left untreated. Therefore, it is essential to clean the wound thoroughly and seek medical attention if necessary. With proper treatment and care, most puncture wounds heal completely and without any long-term effects.
