She learned the pathology reports from her neurosurgery, confirming she was born with spina bifida and tethered cord syndrome. National Institutes of Health, "Spina Bifida Fact Sheet", NINDS, Publication date January 2021, Prepared by: What are the signs and symptoms of Pediatric Tethered Cord? This condition is closely associated with spina bifida, a birth defect in which the spinal cord does not close properly during fetal development. Studies show that women of childbearing age who add folic acid to their diets can significantly reduce the risk of having a child with a neural tube defect. The term “occult tethered cord” (OTCS) refers to where the MRI shows a normal position of … As the spinal columngrows faster than the cord, tethering lesions cause progressive stretching of the spinal cord. Get the latest public health information from HHS Treatment for progressive tethering of the spinal cord (called tethered cord syndrome) can be treated with surgery to help prevent further neurological deterioration. Results of the Management of Myelomeningocele Study (MOMS) (see Prenatal Surgery) showed significant benefit to the developing baby. Tethering of the spinal cord is a condition in which the spinal cord becomes attached to the spinal column via surrounding structures. “Split Spine” caused by incomplete closure of the neural tube, usually in the lumbar or sacral First trimester screens for chromosomal abnormalities also exist but signs of spina bifida are not evident until the second trimester when the MSAFP screening is performed. Developmental studies. There is a well recognised association of tethered spinal cord in patients with spina bifida cystica [ 1 ]. It can be congenital (the person is born with it) or acquired later in life. This study will shed light on how folic acid prevents spina bifida and may lead to improved forms of folate supplements. This study was funded by the National Institutes of Health's Eunice Kennedy Shriver National Institute of Child Health and Human Development. Tel: 914-997-4488; 888-MODIMES (663-4637) If left untreated, this condition can lead to neurological damage as … P.O. Spina bifida, tethered cord and regional anaesthesia. They can come from a variety of causes. TCS in adults is an uncommon entity that … RePORTER also includes links to publications and resources from these projects. Many people with open spina bifida have tethered spinal cords. If it’s the later, there is usually something pulling on the filum terminale or it’s stuck on a physical obstruction or scarred down. Normally, the spinal cord hangs loose in the canal, freely moving up and down with growth, bending and stretching. During that appointment, she hears her spinal cord is permanently damaged, and the spasticity is permanent as well. This story focuses on a 27-year-old woman after she meets with her neurosurgeon. Spina bifida is a birth defect that mainly affects the spine. While all forms of Spina Bifida can be accompanied by spinal cord tethering, it rarely occurs with Spina Occulta. Data concerning acquired tethered cord from prior myelomeningocele repair were excluded. The location of the defect on the spine often determines the type of assistive devices needed. Paraparesis improved postoperatively in both cats. The most common screening methods used to look for spina bifida during pregnancy are maternal serum alpha fetoprotein (MSAFP) screening and fetal ultrasound. For more information on neurological disorders or research programs funded by the National Institute of Neurological Disorders and Stroke, contact the Institute's Brain Resources and Information Network (BRAIN) at: BRAIN Spina Bifida What is spina bifida? A histopathological examination confirmed the diagnosis of a meningomyelocele in case 1 and a meningocele in case 2. The lower end of a normal spinal cord is found in the ... is a form of spina bifida (split spine) in which a segment of the spinal cord is exposed along the midline of … How a tethered spinal cord affects the spine in children and adults, The signs and symptoms of tethered spinal cord syndrome, such as sensory disturbance, significant muscle weakness, pain, and incontinence, How spinal cord tethering occurs in Myelomeningocele, and how it can lead to progressive neurological, urological, or orthopedic deterioration, The factors that play into the decision whether to perform surgery to untether the spinal cord and what typically happens after untethering surgery, The role of medication, alternative therapy, rest, and physical therapy in the treatment of symptomatic tethered cord, Complications of untethering, and whether it could be necessary to repeat untethering, Guidelines for the Care of People with Spina Bifida. Some individuals with myelomeningocele or closed neural tube defects require assistive devices for mobility such as braces, walkers, crutches, or wheelchairs. Women who already have a child with spina bifida, who have spina bifida themselves, or who have already had a pregnancy affected by any neural tube defect are at greater risk of having another child with a neural tube defect. However, some mild cases may go unnoticed until after birth (postnatal). Some children may be able to urinate typically, but most will need to drain their bladders with a catheter or thin tube 4-6 times a day to remain dry in between and to prevent kidney damage. The most common problem that can occur with this form of spina bifida is a tethered spinal cord. Lipomeningocele is a variation in which a fatty mass over the spine is attached (tethered) to the spinal cord and pulls on it. Children with myelomeningocele usually have some degree of delayed mobility, so they are referred to physical therapists early on to maximize their strength and function. The baby will be diagnosed when they are born with a bubble on their back. Often, abnormalities of the brain (such as hydrocephalus, described below) accompany abnormalities of the spine because the neural tube closes first in the middle and then closure proceeds both upward and downward—meaning that if something happens that prevents normal formation of the spine, it may also prevent normal formation of the part of the brain that is forming (closing) at the same time. To evaluate for hydrocephalus, the doctor will request a head ultrasound, CT or MRI to look for extra cerebrospinal fluid inside the brain. Normally, the spinal cord hangs loose in the canal, freely bending and stretching and moving up and down as the body grows. Each year approximately 1,400 babies born in the United States have spina bifida, according to the U.S. Centers for Disease Control and Prevention. The second trimester MSAFP screen may be performed alone or as part of a larger, multiple-marker screen. Otherwise, it can stretch (especially during a growth spurt) and lead to pain, trouble walking, and loss of bladder (pee) control. Myelomeningocele -- the most common and severe form of spina bifida in which the spinal cord and nerves develop outside of the body and are contained in a fluid-filled sac that is visible outside of the back. Although taking this vitamin cannot guarantee having a healthy baby, it can help. Get the latest funding, research, and public health information from NINDS This type of tethered spinal cord syndrome appears to be the result of improper growth of the neural tube during fetal development, and is closely linked to spina bifida. Children with myelomeningocele and some closed neural tube defects have damage to the lowest spinal nerves which control typical bowel and bladder function. Various congenital anomalies, particularly spina bifida, are often associated with congenital tethered cord syndrome. How can I help with research? Multiple surgeries may be required to replace the shunt, which may become clogged, infected, or disconnected. It is pulled tight, where normally the spinal cord hangs loose in the spinal canal. Usually the spinal cord and nerves float freely. The treatments for Spina Bifida vary on the severity of the disease. group of neurological disorders that cause the pulling of the spinal cord at the base of spinal canal. These symptoms of Spina Bifida Occulta could be caused by a tethered cord include pain, leg weakness, birthmark, bladder dysfunction, numbness, and others. Information also is available from the following organizations: Eunice Kennedy Shriver National Institute of Child Health and Human Development This is a result of how their nerves and spinal cord developed during pregnancy. To prevent bowel accidents many people with myelomeningocele and closed neural type defects will use rectal medications or large volume enemas to have planned bowel movements. Spina bifida occulta is usually found when x-rays are done for another reason. Tethered cord syndrome is the most common complication of spina bifida occulta. Many multivitamins contain the recommended dosage of folic acid as well. National Institute of Neurological Disorders and Stroke This information does not constitute medical advice for any individual. They may also develop benign fatty collections within the spinal cord (lipomyelomeningocele) which also can cause tethered cord syndrome which requires evaluation and treatment. Children with a defect lower on the spine usually have more strength in the legs. The specific spinal cord lesions are quite variable, and include the spinal lipoma (lipomyelomeningocele), the split spinal cord, dermal sinus tract and simple tethered cord (also called short filum, fat filum or filum lipoma). In most people the spine grows faster than the spinal cord during development which causes the end of the spinal cord to appear to rise relative to the bony spine next … ©2021 Spina Bifida Association of America. Washington, DC 20007-4266 Normally in the first month of pregnancy, a special set of cells forms the “neural tube.” The top of the tube becomes the brain and the remainder becomes the spinal cord and structures around it. Many people with open spina bifida have tethered spinal cords. National Library of Medicine Because fetal surgery has shown promise, NINDS-funded researchers are also developing new methods, such as stem cell patches and tissue engineering, to add to the prenatal repair of spinal defects. Treatment for bladder and bowel dysfunction typically begins soon after birth. They are more likely to require a caesarian delivery and traditionally neuraxial anesthesia has been avoided due to concerns of worsening neurologic disability. Generally, people with spina bifida occulta will not need any treatment. In addition, NINDS-supported scientists are working to identify, characterize, and evaluate genes involved in neural tube defects. How is spina bifida diagnosed? The MRI may show low lying conus (below the mid L2 level), fatty infiltration, a stretched or thickened filum, a syrinx in the lower spinal cord, scoliosis or spina bifida occulta. Ali L, Stocks GM. NINDS supports and conducts a wide range of basic research studies to understand how the brain and nervous system develop. Surgery. 1. 2005 Nov;60(11):1149-50. These researchers are also studying gene expression during the process of normal neural tube closure, which will provide information on the human nervous system during development. 800-370-2943 or 888-320-6942 (TTY), Spina Bifida Association When this happens, the spinal cord stretches as a person grows, which can permanently damage the spinal nerves. Myelomeningocele This is the most severe form of spina bifida, where the spinal cord is visible outside of the body at birth. Scientists suspect genetic, nutritional, and environmental factors all play a role in spina bifida. Normally, the spinal cord hangs loose in the canal, freely bending and stretching and moving up and down as the body grows. A person’s spinal cord runs from their brain down their spinal column. Although prenatal surgery poses some risk to the fetus as well as to the mother, the benefits are promising and are still being studied. Mild cases of spina bifida (occulta, closed neural tube defects) not diagnosed during prenatal testing may be detected postnatally using ultrasound or X-ray imaging to look at the spine. Prenatal (before birth) surgery involves opening the mother’s abdomen and uterus (or womb) and sewing shut the abnormal opening over the developing baby’s spinal cord. View Spina bifida.ptt.ppt from ECON 344 at Egerton University. Get the latest public health information from CDC. Kidneys are monitored closely so that medications or surgeries can be performed to prevent renal failure. The goal is to understand the genetics of neural tube closure and to develop information that will lead to improved clinical care, treatment, and genetic counseling. All Rights Reserved. In one study supported by NINDS, scientists are looking at the hereditary basis of neural tube defects and hope to find the genetic factors that make some children more likely to have a neural tube defect. Therefore, a child born with these types of spina bifida who has not undergone prenatal surgery will have surgery to close the defect and minimize the risk of infection or further trauma within the first few days of life. Box 5801 Preventing infection of the exposed nerves/tissues is the first step and surgery usually follows. There is no cure but most people with spina bifida lead long and productive lives. Bethesda, MD 20824 More information about research on spina bifida supported by NINDS and other NIH Institutes and Centers can be found using NIH RePORTER, a searchable database of current and past research projects supported by NIH and other federal agencies. Many people with open spina bifida have tethered spinal cords. How is spina bifida treated? 800-352-9424. PMID: 16229704 [PubMed - indexed for MEDLINE] Box 3006 Therefore, it is recommended that all women of childbearing age take a daily vitamin supplement with 400 micrograms of folic acid before and during early pregnancy. People with spina bifida have different abilities and medical issues. Get the latest research information from NIH | Español Spina bifida is a birth defect due to incomplete closure of the posterior spinal cord and bony vertebral arch (lamina). Nuclear Medicine Tests … T1-weighted MRI of spinal cord tethered by a lipomyelomeningocele: Shown is the spinal cord with an intradural lipoma leaving its dorsal surface at L2-3. Other scientists are studying genetic risk factors for spina bifida, especially those that reduce the effectiveness of folic acid in preventing spina bifida. As special cases may vary from the general information presented here, SBA advises readers to consult a qualified medical or other professional on an individual basis. These women should take a higher prescription dose of folic acid before and early in pregnancy. Where can I get more information? askus@marchofdimes.com Download PDF 701.28KB Tethering of the spinal cord is a condition in which the spinal cord becomes attached to the spinal column via surrounding structures.

In tethered spinal cord cases spina bifida can be accompanied by tethering of the spinal cord but in rare cases with Spina bifida occulta. In this paper, we review the major publications that discuss the congenital tethered spinal cord (spina bifida occulta) presenting in adulthood. P.O. Genetic studies. However, a tethered spinal cord does not move; it is pulled tightly at the end. How does folic acid help? Tethered cord syndrome secondary to spina bifida aperta was suspected in both cats. Spina bifida’s impact is determined by the type of defect and in the case of myelomeningocele and closed neural tube defects the size and location of the malformation. The most frequent tethered cord patient is usually a kid with Spina Bifida. Tethered cord due to spina bifida occulta presenting in adulthood: a tricenter review of 61 patients. The procedure does not restore lost neurological function that happened before the surgery, but may prevent additional damage from occurring during the rest of the pregnancy. Both healthy individuals and those with a disease or condition can participate in medical research studies (sometimes called clinical trials or protocols) to help researchers better understand a disease and perhaps develop new treatments. This reduces blood flow to the spinal nerves and damages the spinal cord from the stretching and the decreased blood supply. Treatment depends on the type of spina bifida a person has. Sometimes a tethered cord needs to be released with surgery. It is associated with all types of spina bifida. Very mild forms of spinal bifida are found when doing tests for other conditions or may never be detected. NW The National Institute of Neurological Disorders and Stroke (NINDS), one of the National Institutes of Health (NIH), is the primary federal supporter of research on brain and nervous system disorders. Most people with myelomeningocele have hydrocephalus and most of them will need a shunt placed as an infant. Multiple-marker screens can look for neural tube defects and other birth defects, including Down syndrome and other chromosomal abnormalities. It is pulled tightly Consider joining a clinical study. Tethered cord syndrome. Other NIH research efforts. Learn about 3 types of spina bifida, causes, diagnosis, and treatment. NINDS health-related material is provided for information purposes only and does not necessarily represent endorsement by or an official position of the National Institute of Neurological Disorders and Stroke or any other Federal agency. Tethering can happen before or after birth in children and adults with Spina Bífida, and most often occurs in the lower (lumbar) level of the spine. Tethered spinal cord syndrome may go undiagnosed until adulthood, when pain, sensory and motor problems, and loss of bowel and bladder control emerge. Fetal surgery can also be performed during pregnancy. Children with myelomeningocele usually have hydrocephalus and may require surgery to help drain fluid in the brain, such as the placement of a shunt or ETV. A tethered spinal cord does not move. The symptoms of spina bifida vary from person to person, depending on the type and level of involvement. We would like to report a case of tethered spinal cord in a parturient with spina bifida occulta. Rockville, MD  20847 Doctors may use magnetic resonance imaging (MRI) or a computed tomography (CT) scan to get a clearer view of the spinal cord and vertebrae. Data from the 2012 study showed that prenatal surgery reduced the need to drain fluid from the brain, improved mobility, and increased the chances that a child will be able to walk independently early on. What is Tethered Spinal Cord Syndrome? Meningocele sbaa@sbaa.org The term occult spinal dysraphism (OSD) encompasses a group of abnormalities that occur during the development of a human embryo, beginning in the third week of gestation. These studies contribute to a greater understanding of neural tube defects such as spina bifida and offer hope for new ways to treat and potentially prevent these disorders as well as other birth defects. 4590 MacArthur Blvd. The term neural tube defect describes a group of conditions, including spina bifida, that occur when the neural tube does not close all the way. Spinal cord injuries are just that, injuries that cause damage to the spinal cord. Closed neural tube defects are often recognized at birth due to an abnormal fatty mass, tuft or clump of hair, or a small dimple or birthmark on the skin at the site of the spinal malformation. In addition to NINDS, other NIH Institutes support research on spina bifida and neural tube defects. Spina bifida. All NINDS-prepared information is in the public domain and may be freely copied. They may be able to walk independently, or they may use crutches, leg braces, walkers, and wheelchairs depending on the activity. Excision of the fistula and release of the tethered spinal cord was performed. Suite 250 Children with a closed neural tube defect may need surgery to prevent further complications such as weakness and bowel and bladder function. A tethered spinal cord is attached to the spinal canal. The exact cause of spina bifida is unknown. What research is being done? A tethered cord is a spinal cord that can't move freely inside the spinal canal. Some people with spina bifida occulta also have a tethered cord. A doctor can also perform an amniocentesis test. Folic acid, also called folate, is an important vitamin for the development of a healthy fetus. Many foods—such as some breakfast cereals, enriched breads, flours, pastas, rice, and other grain products—are now fortified with folic acid. Bethesda, MD 20892. Some children with myelomeningocele and closed neural tube defects will need surgery to improve the alignment of their feet, legs, or spine. Anaesthesia. White Plains, NY 10605 Your child might have weakness in the arms and legs, back pain and problems controlling her bladder because of the tethered cord. Close follow-up with a spina bifida specialty clinic is recommended to develop a safe bowel and bladder program. Myelomeningocele and meningocele require a surgery to close the bubble shortly after birth to prevent infection such as meningitis. Babies born with spina bifida … Adult-age presentation of a congenital tethered cord is unusual. In spina bifida, the neural tube doesn’t close all the way and some of the bones of the spine don’t close in the back. This happens when the spinal cord becomes abnormally attached to the body, causing stretching of the cord. The Management of Myelomeningocele Study (MOMS) showed that prenatal surgery to close the defect in the spinal cord improved outcomes compared to children who had postnatal surgery for spina bifida. Women with spina bifida present both obstetrical and anesthesia challenges. a neurological disorder caused by tissue attachments that limit the movement of the spinal cord within the spinal column. Tethered cord syndrome can occur with all forms of spina bifida, although it is very rare in individuals with spina bifida occulta. What is spina bifida? Tethered cord syndrome is associated with Fax: 202-944-3295, March of Dimes Enter “spina bifida” to start your search. Information Resource Center Credit to the NINDS or the NIH is appreciated. Children with a defect high on the spine will have little movement of the legs and will use a wheelchair for mobility. Foods high in folic acid include dark green vegetables, egg yolks, and some fruits. Tethered spinal cord syndrome is a congenital abnormality that results in the lower end of the spinal cord becoming fixed or attached in place, which causes intermittent pulling or stretching of the spinal cord. A tethered cord does not move. Sometimes people with spina bifida occulta can have complications that do affect the nerves of the spine. Both often lead to nerve damage in the spine, so the symptoms of that can be similar. Tethering of the spinal cord tends to occur in the cases of Spina bifida with mylomeningocele. Abnormal traction leads to chronic ischemic changes and neuronal dysfunction. As they do in children, the authors recommend early surg …. 1275 Mamaroneck Avenue Tel: 202-944-3285; 800-621-3141 A tethered cord may go undiagnosed until adulthood when sometimes complex and severe symptoms come on slowly over time. Complications can arise from your Spina Bifida such as hydrocephalus or tethered cord. For information about clinical studies on disorders including spina bifida and how to participate in one, please contact the NIH’s Patient Recruitment and Public Liaison office at 800-411-1222 or visit the Clinicaltrials.gov website. For people living with Spina Bifida, their spinal cord at birth is usually low-lying or tethered. Office of Neuroscience Communications and Engagement A tethered cord means that there is some type of tissue attached to and pulling the cord down. There are four types of spina bifida:   occulta, closed neural tube defects, meningocele, and myelomeningocele. In most cases, spina bifida is diagnosed before birth (prenatal). A tethered spinal cord is characterized by an abnormal attachment of the spinal cord to the surrounding tissues. This is thought to protect the baby’s spinal cord from ongoing damage in the uterus. In rare cases, myelomeningocele and meningocele are not diagnosed during routine prenatal tests. National Institutes of Health In treating myelomeningocele and meningocele, the key priorities are to prevent infection from developing in the exposed nerves and spinal cord through the spinal defect, and to protect the exposed nerves and spinal cord from additional trauma. Advice on the treatment or care of an individual patient should be obtained through consultation with a physician who has examined that patient or is familiar with that patient's medical history. Findings may lead to ways to prevent these disorders. Babies with myelomeningocele and closed neural tube defects may have muscle weakness in their feet, hips, and legs that result in joint deformities first noticed at birth. In tethered cord syndrome, spinal cord is attached to the lower end of the spinal canal and stretch is applied on the spinal cord when the spine is bent causing tearing of the spinal cord and any spinal nerves emerging from the spinal cord. NINDS conducts research in its laboratories at the NIH in Bethesda, Maryland, and supports research through grants to major medical institutions across the country.
