A familial asymptomatic os odontoideum with a Klippel-Feil type II fusion of C-2 and C-3 is reported. The pattern of inheritance within this family is consistent with that of autosomal dominance. The index case, a 16-year-old boy, was studied with plain cervical spine x-ray films, lateral cervical tomography in flexion and extension, fluoroscopic evaluation of the subluxation, and magnetic resonance (MR) imaging of the spine in flexion and extension. In spite of the subluxation noted on flexion and extension, there was no evidence of cord compression on MR imaging. The etiology and management of this condition are discussed.
报告了一例家族性无症状齿状突骨，伴有C2和C3的Klippel-Feil II型融合。该家族的遗传模式符合常染色体显性遗传。索引病例为一名16岁男孩，接受了颈椎正侧位X线片、颈椎屈伸位断层扫描、半脱位的透视评估以及颈椎屈伸位磁共振成像（MR）检查。尽管在屈伸位观察到半脱位，但MR成像未显示脊髓受压迹象。本文讨论了该疾病的病因及治疗方法。
