In 1987, Carson made medical history with an operation to separate a pair of Siamese twins. The Binder twins were born joined at the back of the head. Operations to separate twins joined in this way had always failed, resulting in the death of one or both of the infants. Carson agreed to undertake the operation. A 70-member surgical team, led by Dr. Carson, worked for 22 hours. At the end, the twins were successfully separated and can now survive independently.
