Macey And Mackenzie Garrison, Conjoined Twins

7-year-old girls Macey and Mackenzie Garrison from Iowa were born as conjoined twins sharing a third leg. They were successfully separated during a 24-hour operation. Now girls live a normal life and even go to gym and ride horses.
Conjoined twins (also known as Siamese twins) are identical twins whose bodies are joined in utero. A rare phenomenon, the occurrence is estimated to range from 1 in 50,000 births to 1 in 100,000 births, with a somewhat higher incidence in Southwest Asia and Africa. Approximately half are stillborn, and a smaller fraction of pairs born alive have abnormalities incompatible with life. The overall survival rate for conjoined twins is approximately 25%. The condition is more frequently found among females, with a ratio of 3:1.
