Brazil's Kaka Shakes Hands With Bionic Boy

A six-year-old Brazilian boy has received a bionic arm from fellow Brazilian Kaka, the former AC Milan and Real Madrid star and one of the world's top footballers.

Paulo Costa Boa Nova was born without part of his arm due to a genetic defect.

His difficulty came to the attention of students at the University of Central Florida - calling themselves Limbitless Solutions - and 3D printing manufacturer, Stratasys, who worked with students to create an arm for the young boy.

Paulo was brought over to Orlando and, through the Orlando City Soccer Club, presented with his new limb.

After shaking hands with Kaka, he was given the chance to play some football with the team captain and other players, including the UCF students who are studying in different fields and come together to build bespoke hands and arms for free.

Paulo is the first person outside the US to be given such a limb.

"This is what it is all about," said Albert Manero, charity founder and mechanical engineering doctoral student, as he watched Paulo flex his new arm and smile.

"To change a life, to make a difference. That's why we do this."

Kaka, 33, won the Champions League with AC Milan and was named 2007 World Footballer of the Year and Ballon d'Or winner before making a big money move to Real Madrid.

He has made 89 appearances for the Brazil national team, scoring 29 goals. He was part of the squad which won the 2002 World Cup, also competing in 2006 and 2010.
