Fifteen-month-old twins Mohamed and Souleymane were diagnosed as Siamese twins before they were born. These two boys weighted only 1.7 pounds each were conjoined at the base of the spine and kept in the hospital until they gained enough strength to be operated.

Their surgery took place on December 15 and is first of its kind in France. Similar surgeries have already been performed in Britain, South Africa and Canada and in Singapore, such surgeries represent a routine.

These kinds of surgeries are dangerous because there is a risk of developing paralysis and a type of infection that could develop into meningitis.

However, the twins’ operation went well, and both of the boys moved their legs and feet after they had woken up. Doctors say their chances of normal childhood are good.
