Certain scenarios should raise suspicion for WFBs.  To name a few:

•    Stepping on glass
•    Punching through a window
•    Motor vehicle collision wounds
•    Wounds on the sole of the foot
•    Objects that fragment while in one’s hand
•    Perioral wounds with broken teeth
•    Falling in gravel or soil
•    Scalp wound from glass
•    Punctures

Wounds should be palpated for FBs, but any probing should occur with a metal instrument rather than a gloved finger.  The most important part of the examination is wound exploration, which should be performed in a bloodless field with anesthesia when appropriate.
