Gemelas siamesas

Abigail "Abby" Loraine Hensel and Brittany "Britty" Lee Hensel (born March 7, 1990) are highly symmetric dicephalic parapagus conjoined twins, and further, tribrachius, bipedus. They have two spinesand separate half-sacrums, which converge distally within a slightly broad pelvis. Each controls and senses her corresponding arm and leg; a third, rudimentary central arm was amputated in infancy.Brittany's head is about 15 degrees laterally outward, while Abby's head tilts laterally outward about 5 degrees, causing Brittany to appear to be slightly shorter. They were raised in New Germany,Minnesota and attended Lutheran High School affiliated with the Missouri Synod in Mayer, Minnesota. At age 12, they underwent surgery at Gillette Children's Specialty Healthcare to correct scoliosis andto expand their chest cavity to prevent future difficulties with breathing.

Each of the twins manages one side of their conjoined body and are quite effective in cooperatively using their limbswhen both hands or both legs are required. By coordinating their efforts, they are able to walk, run and ride a bicycle normally — all tasks that they learned at a normal speed. Each writes with herhand. Together, they can type on a computer keyboard at a normal speed. The sense of touch of each is restricted to her body half; this shades off at the midsagittal plane such that there is a smallamount of overlap at the midline.
Upon their birth, their parents rejected the option to attempt surgical separation after hearing from doctors that it was not likely that both girls would survive theoperation. As the girls grew and learned to walk and develop other skills, the parents confirmed their decision against separation, arguing that the quality of life for the surviving twin or twins livingseparately would be less than their quality of life as conjoined beings
They both successfully passed their driver's license exam, both the written and driving tests. They had to take the tests...
