The true pathogenesis of spinal longitudinal fracture is still unclear. At present, most scholars agree with the “unified theory” proposed by Pang et al. in 1992, that spinal cord longitudinal clefts are caused by abnormal development during the closure of the embryonic neural tube, i.e., at the time of neural tube closure, a paramedian tube surrounded by the mesoderm is formed between the yolk sac and the amnion, and an endodermal canal splitting the spinal cord and neural plate is formed, resulting in the appearance of two neural tubes. The Pang subtype is similar to other subtypes. Pang staging has the advantage of being less confusing on imaging than other staging methods and is a better guide to surgical planning. There are two main types: Type I, in which the two halves of the spinal cord have their own separate dural canal with a bony or cartilaginous septum; and Type II, in which both halves of the spinal cord are located within a common dura with a fibrous septum. The symptoms are classified as asymptomatic, mild, moderate and severe with reference to Hoffman et al. Mild degree: basically smooth urination with occasional dribbling, occasional dry stool, no foot deformity, no decrease in muscle strength of lower limbs. Moderate: poor urination, dribbling, dry stool, foot deformity, no or mild lower limb muscle atrophy, able to walk. Severe: poor urination, incomplete dripping, and urinary retention. Dry stools and difficulty in defecation. Significant inversion deformity of the foot, significant muscle atrophy of the lower limbs, difficulty in walking. Intraoperative resection of the osseous partition is seen. Minimally invasive surgery is currently the only treatment for spinal cord longitudinal fracture. As the body grows taller, the spinal cord, especially the ends of the spinal cord, is constantly stretched and cut, causing spinal cord injury. As the spinal cord and the spinal column grows and becomes unequal in length, the spinal cord is stretched and cut at intervals, and the dysfunction becomes more severe. In addition, children’s deformed bone tissue is small, and the majority of cartilage components, so the surgery is easy to operate. The principles of surgery are 1, microscopic operation. 2, the application of high-speed grinding drill, nerve stripper to protect the spinal cord. 3.Prohibit excessive stretching and vibration of the spinal cord. 4.Remove the bony partition as much as possible, but if the bony partition is wide, it is difficult to remove the whole partition, only the caudal partition can be removed to release the division of the spinal cord. 5.Protect the blood vessels supplying the spinal cord.
