Your exampled article did not show one single death from an injury similar. It just showed three cases of a DVT that formed (out of how many injuries)? Yes Virchow's factors can lead to clotting, but again present real data onto how many injuries cause clots that then lead to death. Since the coroner deemed the PE to be from the leg, then yes it was injury related. I do not think the original commenter read the coroner conclusion. She wasn't being dismissive but rather cautious to make a conclusion before that detail was written on the discussion messaging order.
