Puncture wounds without a foreign body are caused by an object penetrating the skin and underlying tissues, such as a needle, nail, or sharp object.
Diagnosis of a puncture wound without a foreign body can usually be made based on the patient’s history and physical examination. The wound will appear as a small puncture or laceration, which may be accompanied by swelling and redness.
Differential diagnoses to consider include other types of wounds, such as lacerations, abrasions, and contusions.
Treatment of a puncture wound without a foreign body will depend on its severity. Minor wounds may be treated with cleaning and bandaging. More severe wounds may require antibiotics and possibly surgery.
Generally, the prognosis for puncture wounds without foreign bodies is good, as long as the wound is properly treated. However, if the wound becomes infected, the prognosis may be worse.
