1Q: What are the general symptoms of spinal cord tethering? A: In order generally appears dripping urine, dry stool, deformation of both feet or one foot, or even muscle atrophy of lower limbs and paralysis. If there is neurogenic bladder can lead to bladder enlargement, ureteral dilatation, hydronephrosis, and finally renal failure, uremia, and death. 2Q: What is the main purpose of spinal cord tethering surgery? A: To stop or delay the further development of the disease process, for example, patients with only urinary and fecal dysfunction can avoid muscle atrophy and paralysis of the lower limbs after surgery. 3Q: What is the best time to operate on spinal cord tethering? A: The earlier the surgery, the better, so as to avoid the damage caused by the spinal cord tethering due to the growth of the body. However, the younger the child is, the higher the surgical requirements are, so it is not a specialty that cannot be performed. 4Q: Is it necessary to operate on adults who are no longer tall? A: Yes, although the body is no longer tall, but often bending back, bending back will increase the distance, pulling the spinal cord, aggravating the damage to the spinal cord. Therefore, there is still a need for surgery to release the spinal cord tethering in adults. The oldest of the cases we operated on was 56 years old, and her condition improved after surgery. 5Q: Will there be a recurrence after surgery? A: Applying artificial spinal membrane and encouraging early activity can prevent recurrence. 6 How to deal with congenital spina bifida itself? A: If the spina bifida is small and does not affect the stability of the spine, it can be left untreated. If the bifida is large and the vertebral plate is defective, i.e., the spine is unstable, and the spinal cord is poorly protected by the returned spinal cord, a titanium plate can be used to reconstruct the spinal canal. 7Q: Why is postoperative cerebrospinal fluid leakage the most likely complication? A: In children with congenital spina bifida, various tissues (dura, bone, muscle) are defective at the surgical site, and cerebrospinal fluid can easily leak out along the tissue spaces after surgery. 8Q: Some children have been operated before but the result is not good, can they be operated again? A: Children who have undergone surgery before, but only removed the large lumbosacral pouch (i.e., bulging spinal capsule and lipoma) without dealing with the spinal cord lesions in the spinal canal, which is actually equivalent to “cosmetic” surgery on the lumbosacral region, resulting in ineffectiveness or aggravation. For these patients, a new spinal cord tethering release is needed to truly free the end of the spinal cord completely. 9Q: Why does the patient have normal urine and stool before surgery, but dripping urine and dry stool after surgery? A: Patients with spinal cord tethering seem to have “normal” urine and stool before surgery, not necessarily because the nerve function is normal, because the nerve is in the compensatory stage during the course of the disease, so that the bladder sphincter and the forced urinary muscle reach a state of equilibrium, which is normal for urination. This dysfunction will be improved with the gradual recovery of the nerve (3 weeks-3 months) and the re-establishment of the equilibrium state, and this process is reversible. In contrast, the urinary dysfunction eventually caused by non-surgery is not recoverable and is irreversible. The same holds true for stool performance. 10Q: Why do some infants and young children with surgery still have foot deformities after surgery? A: Fetuses with spinal cord tethering have already suffered from nerve damage due to spinal cord strain during the long-term maternal gestation process. After surgery, as the child grows up, the normal nerves have good nutritional support for the muscles they innervate and make them strong and powerful, while the nerves with loss of function have no nutritional support for the muscles they innervate and cause them to be weak and ineffective. This imbalance in muscle strength leads to deformation of the foot due to pulling by a strong group of muscles. It is manifested as clubfoot or hooked foot.
