The authors report that C-1 horizontal fractures also occur in association with severe distraction injuries of the craniocervical junction.<\/jats:p><\/jats:sec>Methods<\/jats:title>The authors retrospectively reviewed imaging studies obtained in all surviving patients in whom unstable distraction injuries of the craniocervical junction were diagnosed and in whom surgery was performed at their institution between 1995 and 2009.
