Metal Detector England

that the metal screw in my ankle that I broke the metal detector at the airport?
i double ankle fracture over 2 years and had a steel bolt inserted through a bone that must remain in place. I'm flying to England in a few days and wondered if this would be a problem in the airport security.
I have two metal screws in my ankle and I never had problems with airport security or any security zone detectors of metals used.
Metal detecting in England, October 2007 found my 5th celtic gold coin.
