title: Congenital atlantoaxial fusion. A case report.
abstract: An adult patient, after a minor fall, had a painful neck, and roentgenograms of the affected area showed a separate odontoid with the remnant fused to the anterior ring of the atlas. The multiple nature of the anomalies, coupled with the lack of significant trauma, indicated that the finding was that of congenital atlantoaxial fusion.
