Finger - Foreign bodies

  • Fingers are a common site for foreign bodies
  • Always rely on at least 2 views and relate the position of the foreign body to the site of the skin wound
  • Dense materials like glass and metal are easily detected. Less dense material such as wood may not be visible, in which case imaging with ultrasound may be helpful
  • In this case a radio-opaque foreign body is seen at the site of the marker
  • A second foreign body is also seen more proximally
