Spinal cord tethering syndrome may be caused by congenital (e.g., viral infection in early pregnancy of the mother, lack of vegetables and severe deficiency of folic acid, etc.) or acquired (e.g., lumbosacral spinal canal surgery) causes, during human growth and development, the spinal canal grows faster than the spinal cord, so the lower end of the spinal cord is gradually elevated relative to the lower end of the spinal canal The lower end of the spinal cord is tethered and fixed, and the spinal cord is stretched and undergoes ischemic pathological changes, resulting in A series of neurological dysfunctions and deformities. It is one of the main pathological mechanisms leading to neurological symptoms due to various congenital developmental abnormalities, and the resulting series of clinical manifestations is called spinal cord tethering syndrome. The following are five features of spinal cord tethering surgery: 1. The curability of the disease through surgery: congenital neural tube malformation is ultimately anatomically manifested by pathological changes in the spinal cord tethering, which clinically leads to urinary and fecal dysfunction, bipedal inversion deformity, muscle atrophy of both lower extremities (or single limb), and then gradually develop renal insufficiency, paralysis of the lower extremities and other serious complications This is collectively called spinal cord tethering syndrome. Many patients in major hospitals in China are told that the disease is incurable, or some doctors blindly remove the mass, which leads to more serious symptoms. So is this disease incurable? The answer is no, in foreign countries found that this disease in pregnancy the mother can do surgery, and after surgery to continue to nurture the fetus. 2, the severity of the consequences of delayed surgery for the disease: clinically seen very many patients because of the lack of timely surgical treatment or improper surgery, gradually appear urine dripping, dry stool, double or single foot deformation, or even muscle atrophy of the lower limbs, can not walk, manifesting as paralysis, wheelchair, tortured by the disease is extremely painful, and even more so, due to neurogenic bladder, incomplete urination, bladder enlargement, ureter dilatation, hydronephrosis, and finally renal failure, uremia, and lifelong maintenance by dialysis, which otherwise leads to death. The purpose of the operation is to loosen the 5-10 pairs of cauda equina nerves that are attached to the fatty tissue one by one at the end of the terminal filaments, and finally to cut the terminal filaments to make the spinal cord move up automatically to ensure that the symptoms will not be further aggravated and to improve the neurological dysfunction that has already occurred. The procedure is extremely complex, and the slightest mistake during the release will result in irreversible nerve damage. The entire procedure needs to be done under a high-powered microscope and requires intraoperative monitoring with a neurological monitor, as well as extensive experience in spinal surgery. The high risk of postoperative complications is determined by the complexity of the surgery. The incidence of postoperative complications such as loss of limb strength or even paralysis, poorer urinary and fecal function than before surgery, and cerebrospinal fluid leakage is higher even in foreign countries, and because of such high risks, many domestic neurosurgeons and even well-known specialists in large hospitals are reluctant to work in this field, which makes it more difficult to carry out this line of surgery and cannot be popularized. For example, the incidence of cerebrospinal fluid leakage in foreign countries is about 14%, while the incidence of cerebrospinal fluid leakage in our department is only less than 6%. Although postoperative complications are reduced in our department, surgical risks still exist and should not be ignored. 5, the need for postoperative rehabilitation Although the surgery has made the adhesions of the nerves completely loose, the tethered spinal cord fully free, to achieve the normal anatomical state of the spinal cord, but due to their different degrees of deformity, the length of the lesion varies, some although completely free and loosened nerve function has long been lost, postoperative symptoms can not be well improved, which needs to be combined with rehabilitation training. For example, the best rehabilitation method for neurogenic bladder is intermittent catheterization, the weakness of lower limbs requires functional exercises for a certain muscle, and orthopedic shoes or orthopedic surgery are needed for deformed single foot or biped, etc. In conclusion, the treatment of congenital neural tube deformity is a long and complicated process, surgery is the most fundamental and crucial step, and a long rehabilitation is needed, even mental and emotional adjustment and guidance is needed.
