Patient's question:
How many categories can spina bifida be divided into?Doctor's answer:
Hello, hidden spinal dysraphism is generally classified into two types:Type I: Double dural sac and double spinal cord, where the spinal cord is divided into two parts at the longitudinal fissure, each with its own dural sac and arachnoid mater. The two are separated by fibers, cartilage, or bony ridges, causing the spinal cord to be stretched. This type accounts for about 50%.
Type II: The spinal cord is divided into two parts at the longitudinal fissure but shares a single dural sac and arachnoid mater. There is no foreign body pulling on the spinal cord, and no clinical symptoms are produced.
