A puncture wound is a type of penetrating injury caused by a sharp object, such as a nail, needle, or knife. Puncture wounds of the wrist or hand are usually caused by sharp objects that penetrate the skin, such as needles, nails, or knives.
Diagnosis of a puncture wound is usually made by physical examination of the wound. This can include inspection of the wound, feeling for any foreign bodies, and taking a medical history to determine the cause of the wound.
Differential diagnosis of a puncture wound includes other types of penetrating injuries, such as lacerations and abrasions.
Treatment of a puncture wound depends on the severity of the injury and the presence of any foreign bodies. Minor puncture wounds may be treated with wound cleaning and tetanus prophylaxis. In cases of deeper or more severe puncture wounds, a doctor may need to suture the wound or prescribe antibiotics to prevent infection.
The prognosis for a puncture wound is usually good, as long as proper treatment is provided and infection can be avoided. In cases where infection does occur, the prognosis depends on how quickly the infection is treated.
