The new classification for split cord malformation, based on the unified theory of embryogenesis includes two types Type I and II defined on the basis of the nature of the medium septum and the state of the dural tube. According to this, these are the only two essential features needed for typing and there is never an overlap between the two main forms. We have described two cases that defy this theory.
We present two patients with split cord malformation who appear to have a combination of features specific to Type I and Type II. Both patients had a partial bony spur within a single dural sac.
An overlap between the two forms of split cord malformation does exist. The role of meninx primitiva in the formation of median bony septum is debatable.
基于胚胎发生统一理论的脊髓纵裂畸形新分类包括I型和II型，这两种类型是根据中间隔的性质和硬脊膜管的状态来定义的。据此，这是分型所需的仅有的两个基本特征，两种主要形式之间不存在重叠。我们描述了两例不符合该理论的病例。
我们报告了两名脊髓纵裂畸形患者，他们似乎具有I型和II型特有的综合特征。两名患者在单个硬脊膜囊内均有部分骨嵴。
两种形式的脊髓纵裂畸形之间确实存在重叠。原始脑膜在正中骨隔形成中的作用存在争议。
