I broke my ankle 4 months ago and had a plate and 7 screw to repair the fracture. I have had 3 surgeries from this fracture. The hardware was removed on Dec 16th, 2015. A few days ago I was at the Orlando Airport and went through the body scan. After leaving the scan the TSA Agent said "I need to pat down your left ankle". I have seen the pre and post surgery x-rays of my ankle. I know that there is nothing left inside of me. I have the hardware in my possession to prove it. What did they detect in my "left ankle" or was it just a coincidence?
