马尾神经受损机制的研究正在引起人们的重视，我们就这方面的实验研究综述如下。１　马尾神经受压的解剖学基础１－１　马尾神经的结构特点硬膜囊内的马尾神经根有硬膜外间隙和蛛网膜下腔两个代偿间隙，而侧椎管内的神经根则只有一个代偿间隙。因此，侧椎管内的神经根容易受压 Research on the mechanism of cauda equina injury is arousing people’s attention, and we summarize the experimental research in this respect as follows. 1 cauda equina anatomy based on the anatomy of the structure of the 1-1 cauda equina cauda equina dura cauda equina nerve root epidural space and subarachnoid space of two compensation, while the lateral spinal nerve roots Only one compensation gap. Therefore, the nerve root of the lateral spinal canal is easily under pressure
