title: Cervical spondylolysis in children: is it posttraumatic?
abstract: Cervical spondylolysis is a rare defect of unknown etiology. Five cases of cervical spondylolysis as well as two cases of fractures of the pedicles of C2 in infants are presented. Comparison of the cases suggests that a fracture at birth or in infancy may be the cause of some cases of cervical spondylolysis.
