(FoxNews.com) - A 4-year-old boy who was internally decapitated when the car he was riding in crashed during a hail storm was released from the hospital on Sunday and is expected to make a full recovery.

Killian Gonzalez suffered the horrific injury while he and his mother, Brandy, were traveling the icy roads back to Nevada from Idaho after celebrating the boy’s birthday in May, according to a GoFundMe page set up for Killian and Brandy. Their car smashed head-on into another vehicle, fracturing both of Brandy’s legs and her left arm. The other driver was not seriously injured.

Killian, however, had devastating injuries: A right arm fracture, broken ribs, bruised lungs, ruptured spleen – and an internal dislocation of his skull from his spine.

In an internal decapitation, the head is connected to the spine only by strands of tissue or muscle. About 70 percent of those inflicted with the injury die immediately and 15 percent more die at the hospital, according to medical journals.
