Management of foreign bodies in the skin.

Although puncture wounds are common, retained foreign bodies are not. Wounds with a foreign body sensation should be evaluated. The presence of wood or vegetative material, graphite or other pigmenting materials, and pain is an indication for foreign body removal. Radiography may be used to locate foreign bodies for removal, and ultrasonography can be helpful for localizing radiolucent foreign bodies. It is wise to set a time limit for exploration and to have a plan for further evaluation or referral. Injuries at high risk of infection include organic foreign bodies or dirty wounds. These should be treated with plain water irrigation and complete removal of retained fragments. In most cases, antibiotic prophylaxis is not indicated. If a patient presents with an infected wound, the possibility of a retained foreign body should be considered. Tetanus prophylaxis is necessary if there is no knowledge or documentation of tetanus immunization within 10 years, including tetanus immune globulin for the person with a dirty wound whose history of tetanus toxoid doses is unknown or incomplete.
