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.
一名成年患者在轻微跌倒后颈部疼痛，受影响区域的X线片显示齿突分离，残余部分与寰椎前弓融合。这些异常的多发性，加上缺乏明显的外伤，表明这一发现是先天性寰枢椎融合。
