It's interesting that this is what Jane Moore thought her injury was:
"Jane Moore fought back tears as she recalled her time working as a royal correspondent during Princess Diana’s death on Loose Women.
Moore learnt of Princess Di’s ‘heartbreaking’ death while at a colleague’s wedding and initially believed that she had only ‘broken her collarbone’."
