A seven-year-old boy who lost half his skull in a fall has been given a new lease of life thanks to a 3D printed skull.
Teddy Ward was just five when he slipped and fell down a cliff in Topanga Canyon, near Los Angeles.
The impact crushed his head, shattering all of the bone on his left side.
After surgery to replace the skull was unsuccessful, he was sent home with a helmet, ordered to wear it 24 hours a day.
