Day One Hundred & One of Twinipedia Facts
The first twins to be separated were Elizabeth and Catherine Mayer. They were joined "in the region between the Xiphoid process and the umbilicus". Since the Xiphoid process is the tip of your sternal bone that helps keep your rib cage from flopping open, and your umbilicus is basically your belly button region, the girls were joined just below their rib cages and just above their belly buttons. The location these twins are joined is one were the twins are less likely to be connected together by any vital organs other than perhaps their liver/s.
They girls survived the surgery and were the beginning of a long medical history of conjoined twins being separated throughout the world.
