title: Congenital defect of posterior elements of the axis.
abstract: A congenital defect of the posterior elements (spinous process and vertebral arch) of the axis was observed in a 20-year-old man. This anomaly was detected by coincidence during roentgenographic study of the cervical spine for the investigation of headaches and neck pain following trauma. The clinical symptoms were relieved by conservative therapy, and the patient returned to a normal life.
