A simple stereotactic method to isolate and remove foreign bodies.

For the past several years, a simple technique using an image intensifier has been employed to isolate and remove foreign bodies from the extremities. Five consecutive cases were recorded to demonstrate its accuracy and simplicity. After the foreign body was identified by an x-ray film, the wound was infiltrated with local anesthesia and the foreign body was "located" by two venipuncture needles placed with the aid of an image intensifier. A small incision was then made between the needles to locate the foreign body at their tips. In this manner, foreign bodies have been consistently removed successfully in the emergency room in a relatively short period of time.
