The surgeon had never seen anything like it. When 75-year-old Arthur Lampitt of Granite City, Illinois, had an operation on Wednesday to remove a metal object that was lodged in his left arm, no one was quite sure what they'd find. It turned out to be the turn signal from a 1963 Thunderbird that had been embedded in his arm ever since a car accident more than half a century ago. The St. Louis Post-Dispatch recounted the story of Lampitt's medical mystery, which began one day in 1963 when he was driving his brand-new Thunderbird to work. Lampitt crashed head-on into a large truck, totaling his car and breaking his hip. He also suffered cuts from flying debris and broken glass. The wounds healed, and Lampitt went on about his life, getting married in 1965, raising four boys, and working in real estate, appraisals and odd jobs. Then, as Lampitt and his wife Betty told the Post-Dispatch, 10 or 15 years ago he was surprised to set off the metal detector during a visit to a courthouse. He went for an X-ray and doctors discovered a metal rod, about the size of a pencil, lodged in his left arm. Since it didn't cause him any pain or interfere with the use of his arm, doctors told him to just leave it be. So he did -- up until a few weeks ago, when something in his arm seemed to shift. "The arm started bulging," Betty Lampitt told the paper. Whatever was stuck in his arm seemed to be trying to work its way out. Thinking back on that long-ago car accident, Arthur Lampitt developed a theory. He pored over old photographs of the wreck that a friend of his had taken at the time, and noticed that the metal turn signal lever seemed to be missing from the left side of the steering wheel. Could it really have been embedded in his arm all this time? via CBS News.
