Arnold Schwarzenegger's son is expected to make a full recovery after a boogie boarding accident.

Christopher Schwarzenegger, 13 - the youngest son of the former Governor of California and his estranged spouse Maria Shriver - has been in intensive care since the incident in Malibu last Sunday (17.07.11) but the couple have revealed his injuries including a collapsed lung, broken bones and broken ribs are not life threatening.

They said in a statement: "A few days ago our son Christopher suffered an accident at the beach. While it has been a very scary week, Christopher is surrounded by his family and friends. He is a brave boy and is expected to make a full recovery."

The couple also thanked emergency personnel and medical staff for their assistance.

The statement continued: "On behalf of our entire family, we want to sincerely thank the paramedics and lifeguards who responded so swiftly as well as the doctors, nurses, emergency room and hospital staff who have cared for our son."

"They have been extraordinary to him and to us. We thank everyone for their thoughts and prayers and ask for respect and privacy for Christopher and our family."

Maria and Arnold - who split after it was revealed he has a 13-year-old love child with their former housekeeper - have three other kids, Katherine, 21, Christina, 19 and Patrick, 17.
