We describe nuchal cord changes in four children with os odontoideum who had cervical spine magnetic resonance imaging (MRI) before surgery. In these four children, nuchal cord changes consistent with previous trauma were seen. The presence of the nuchal cord changes supports the concept of trauma as an etiologic factor in these four cases. This study supports trauma as an associated factor in patients with os odontoideum.
我们描述了4例齿突骨患儿术前颈椎磁共振成像（MRI）显示的颈髓改变。在这4例患儿中，可见与既往创伤相符的颈髓改变。颈髓改变的存在支持了创伤作为这4例病因的观点。本研究支持创伤是齿突骨患者的一个相关因素。
