脊髓分裂畸形(SCM)是一种罕见的脊柱畸形，其分类仍有争议。关于这个实体的胚胎学基础，目前还没有广泛的共识。由Pang等人提出的统一理论。[神经外科1992；31：451-480]，试图将胚胎发生机制解释为发生在原始神经肠管关闭前后的基本错误。我们报告两个罕见的SCM病例，其骨刺位于背侧。我们分析了病变的放射学、临床和外科特征，不能按照统一的理论进行分类。应进行进一步的胚胎学研究以阐明这些病变的发生机制，在SCM手术中应考虑背侧骨间隔变异。版权所有(C)2002 S.Karger AG，巴塞尔。
Split cord malformations (SCMs) are rare spinal anomalies and their classification is still a matter of debate. There is no widespread consensus on the embryological basis of this entity. The unified theory, proposed by Pang et al. [Neurosurgery 1992;31:451-480], was an attempt to explain the embryogenetic mechanism as a basic error occurring around the time when the primitive neuroenteric canal closes. We report two unusual cases of SCMs with a dorsally situated bony spur. We analyzed the radiological, clinical and surgical features of the lesions and were not able to classify these cases according to the unified theory. Further embryological studies should be conducted to elucidate the mechanisms of occurrence of these lesions, and the dorsal bony septum variant should be considered in SCM surgery.
