Abstract
As a result of the rising threats of terrorism, airport
security has become a major issue. Patients with
orthopaedic implants are concerned that they may
activate alarms at airport security gates. A literature
overview showed that the activation rate of the alarm
by hand-held detectors is higher than for arch detectors
(100% versus 56%). Arch detection rate has significantly
increased from 0% before 1995 up to
83.3% after 1994. Reported factors which influence
detection rates are implant mass, implant combinations,
implant volume, transfer speed, side of
implant, detector model, sensitivity settings, material
and tissue masking. Detection rate has been
improved by more sensitive devices and improved
filter software. Doctors should be able to objectively
inform patients. A form is presented which will easily
inform the airport security staff.
