Surgery Was Not An Option
Naturally, you are probably curious about the anatomy of conjoined twins. So, yes they do have one shared body but you may be surprised to hear they have separate organs. Abby and Brittany each have their own lungs, stomach, spinal cord, spine and heart. Despite this, they share a reproductive system. Unfortunately, surgery to separate them when they were born would have been very risky and dangerous because of this.
Unique Case
Of course, it’s quite obvious that this particular case is unique, but you are probably wondering just how rare it is! Firstly, there’s just a one in 189,000 chance that twins will be born conjoined. As far as Abby and Brittany Hensel go, they’re actually dicephalic parapagus twins, and this means they’re conjoined twins with one body but separate heads. Out of all the conjoined twins, dicephalic parapagus twins make up only 11 percent.
