Occult occipital condyle fracture with normal neurological function and torticollis.

Occipital condyle fracture is a rare and easily neglected fracture. We describe a case of type III fracture with torticollis and normal neurological function. A young woman who had experienced a head injury was suffering from neck pain. Torticollis developed several days later and a CT scan of the cervical spine revealed a type III left occipital condyle fracture. She had no neurological deficits. External cervical traction and 3 months of halo vest immobilization were applied. A follow-up CT scan showed good healing and re-attachment of the bony fragment. The patient recovered well without adverse sequelae. We conclude that physicians should be alert to the possibility of occipital condyle fracture in trauma patients.
