A method and apparatus for automatically identifying surgical implants by
use of a radio-frequency tag (RFID) is disclosed. The method, apparatus,
and system enable a radio-frequency tagged implant to receive an
interrogation signal from a reader and to respond to the interrogation
signal with identifying information about the tagged implants. The
interrogation signal interrogates the implant to ascertain its
information, and the RFID tag affixed on the implant in turn transmits a
signal back to the reader. The method, apparatus, and system can track,
inspect, and verify surgical implants, to assess, for example, any wear
and tear on implants, and/or positional displacement of components of the
implant.
