Myelomeningocele is a serious birth condition in which part of the spine and spinal cord do not form normally, and it is often found before birth or at delivery. People with myelomeningocele may have weakness or paralysis in the legs, trouble with bladder or bowel control, and fluid buildup around the brain. Myelomeningocele is lifelong, and the early signs of myelomeningocele can vary depending on where the opening is along the spine. Not everyone will have the same experience. Treatment usually includes surgery soon after birth and ongoing care such as physical therapy, mobility support, and bladder or bowel management, and survival often depends on severity and access to specialized care.
How many people live with Myelomeningocele?
Worldwide, about 1 million people are estimated to be living with spina bifida (Global Burden of Disease Study 2021); because myelomeningocele is usually described as about three-quarters of spina bifida cases, a rough 70% to 80% range suggests about 700,000 to 800,000 people worldwide are living with myelomeningocele, but this is an estimate rather than a direct count (National Institute of Neurological Disorders and Stroke, 2023). In the United States, about 166,000 people are living with spina bifida (CDC, 2024), which suggests roughly 115,000 to 133,000 people are living with myelomeningocele here using the same range, again as an estimate rather than a direct count.
Overview
MyelomeningoceleSymptoms
Myelomeningocele often affects movement, feeling, and bladder or bowel control. Many living with myelomeningocele have leg weakness or paralysis, foot or spine changes, and skin numbness below the spinal opening. Hydrocephalus can also occur.
Outlook and prognosis
With myelomeningocele, outlook varies, but many people live into adulthood and go to school, work, and build relationships. Long-term health often depends on the level of the spinal opening, movement, bladder and bowel care, and treatment of hydrocephalus.
Causes and risk factors
Myelomeningocele usually develops before birth when the spinal tube does not close fully. Risk rises with low folic acid, certain seizure medicines, diabetes, obesity, high early-pregnancy temperatures, and family history. Most cases are not directly inherited.
Genetic influences
Genetics can raise the chance of myelomeningocele, but it is usually not caused by a single gene change. Many small genetic differences, together with factors like low folate before and during early pregnancy, appear to play the biggest role.
Diagnosis
Myelomeningocele is often recognized at birth from its visible spinal features and a neurologic exam. Doctors usually confirm the diagnosis of myelomeningocele with imaging, such as ultrasound or MRI. Prenatal ultrasound can often detect it before birth.
Treatment and drugs
Myelomeningocele treatment usually starts with surgery soon after birth, or sometimes before birth during pregnancy. Many living with myelomeningocele also need ongoing bladder, bowel, and mobility care, plus physical therapy and treatment for hydrocephalus if it develops.
Symptoms
Many living with myelomeningocele need support with moving around, bladder and bowel care, and protecting areas of skin that cannot feel pain well. The early features of myelomeningocele are often noticed at birth, especially changes in the lower back and in leg movement or feeling. Which features show up depends a lot on where along the spine the opening is, with higher openings usually affecting more of the body. Features vary from person to person and can change over time.
A sac, open area, or thin patch of skin on the back is often visible at birth, usually in the lower spine. Because the nerves are exposed or only lightly covered, the area needs urgent protection and medical care.
Weakness or paralysis in the hips, knees, ankles, or feet is common. For many people with myelomeningocele, this can affect standing, walking, and balance and may mean using braces, walkers, or a wheelchair.
Feeling below the affected spinal level may be reduced or absent. This can make it easy to miss blisters, burns, tight shoes, or pressure sores.
The nerves that help the bladder store and release urine often do not work in the usual way. Many people with myelomeningocele have leaking, trouble emptying fully, or repeated urine infections and may need a catheter routine.
How people usually first notice Myelomeningocele?
Myelomeningocele is usually first recognized before birth, when a prenatal ultrasound shows an opening in the developing spine or a sac on the baby’s back, sometimes supported by a blood test or fetal MRI. When it is first noticed after delivery, doctors and families often see a fluid-filled sac or exposed tissue along the back, most often in the lower spine, and the baby may also have weakness in the legs or trouble moving the feet normally. The first signs of myelomeningocele can vary, but it is most often how myelomeningocele is first noticed: through prenatal screening or clear physical findings at birth rather than symptoms the baby can describe.
Types of Myelomeningocele
No distinct types of Myelomeningocele are widely recognized.
Can I slow down the onset of symptoms?
No. Myelomeningocele, a severe form of spina bifida, develops very early in pregnancy, so there is no proven lifestyle change or treatment that can meaningfully delay the start of symptoms once a baby has it. What is well established is prevention before and very early in pregnancy: taking folic acid and getting good prenatal care can lower the chance of a baby developing spina bifida, but this reduces risk rather than guaranteeing prevention and does not delay symptoms in a baby who is already affected. If your family may be at higher risk, talking with a doctor before pregnancy and getting early specialist care can help with planning and may limit some complications, even though it cannot change when the condition begins.
What genetics can tell you about symptoms
Genetics can explain part of why people with myelomeningocele have different symptoms, but it usually does not predict everything on its own. Small changes in many genes may affect how the spinal cord and surrounding tissues develop, which can influence how severe the condition is, what related problems show up, and sometimes how early they are noticed, although the exact pattern varies widely from one person to another. In everyday life, this means genetic information may help explain differences in movement, bladder or bowel control, learning, or other associated features, but the location and size of the spinal opening and other non-genetic factors are also very important.
Causes and risk factors
Myelomeningocele usually starts very early in pregnancy when the tissue that forms the spine and spinal cord does not close completely. A mix of genetic susceptibility and pregnancy-related factors can raise the chance, and a family history of spina bifida can increase risk. Low folic acid before conception and in early pregnancy is one of the best known risk factors for myelomeningocele. Other risks include certain anti-seizure medicines, diabetes, obesity, and high body temperature from fever, hot tubs, or saunas early in pregnancy. Think of risk factors as pieces of a puzzle, not the whole picture.
What are the most common causes or risk factors?
Myelomeningocele happens when a baby’s spine and spinal cord do not close fully very early in pregnancy. The strongest known risk factors are not getting enough folic acid before and in the first weeks of pregnancy, having a family history of spina bifida or a related birth difference, and certain medicines used for seizures, especially valproate. Risk is also higher with poorly controlled diabetes, obesity, and high body temperature in early pregnancy, such as from a fever or frequent hot tub use.
Environmental and biological risk factors
Risk factors for myelomeningocele matter most around conception and in the first few weeks of pregnancy, often before a missed period. Some risks are carried inside the body, others come from the world around us. Having one or even several of these factors does not mean a baby will definitely be affected, but they can increase the chance.
Folate is needed very early for the spinal tissues to form and close normally. Low folate, and sometimes low vitamin B12, around conception can raise the chance of myelomeningocele. This matters most in the first month of pregnancy.
Some medicines taken in early pregnancy can disrupt early spinal development or interfere with how the body uses folate. The best-known example is valproate, and risk can also rise with a few other medicines that affect folate pathways or cell growth. The amount of risk depends on the drug, dose, and timing.
Diabetes that is present before pregnancy, especially if blood sugar is high early on, is linked with a higher chance of myelomeningocele. The earliest stages of development are the most sensitive, often before routine prenatal visits begin.
Higher body mass index before pregnancy is associated with more neural tube defects. Researchers think inflammation, insulin resistance, and changes in folate handling may all contribute.
Genetic risk factors
When myelomeningocele affects a family, one of the first questions is whether genes played a part and what that means for future pregnancies. Most cases are linked to a mix of genetic influences rather than one single inherited change. Some risk factors are inherited through our genes. Rarely, myelomeningocele is tied to a chromosome difference or a broader genetic syndrome.
Family history: Having a parent, child, or sibling with myelomeningocele can raise the chance in a future pregnancy, although most families still do not have another affected baby. This pattern suggests shared inherited factors, but it usually does not follow a simple one-gene inheritance pattern.
Many genes: In most cases, several genes seem to each add a small amount of risk rather than one gene fully causing the condition. This is why the genetic causes of myelomeningocele are often hard to identify in one clear test result.
Folate genes: Some gene changes may affect how the body transports or uses folate during very early development of the spine and nervous system. These changes may contribute to risk, but they do not explain most cases on their own.
Chromosome differences: A small number of babies with myelomeningocele have an extra, missing, or rearranged piece of chromosome. When this is the cause, myelomeningocele is often one of several medical findings rather than the only issue.
Genetic syndromes: Rarely, myelomeningocele happens as part of a broader genetic syndrome caused by a single gene change. In these situations, genetic testing may help clarify the cause and better estimate the chance of it happening again.
Lifestyle risk factors
Myelomeningocele is present from birth, so lifestyle habits do not cause it. However, how lifestyle affects myelomeningocele can be important for mobility, skin protection, bladder and bowel care, bone health, and day-to-day independence. The most helpful habits are those that reduce complications and support function over time.
Regular, adapted exercise can help maintain strength, joint range, and cardiovascular fitness in people with myelomeningocele. It may also support transfers, wheelchair mobility, standing programs, and overall participation in daily life.
Excess body weight can increase strain on weak muscles and joints and make bracing, walking, or wheelchair use more difficult. A balanced eating pattern and activity plan may lower the risk of pressure injuries, fatigue, and loss of mobility.
Long periods of sitting, poorly fitting braces, and limited repositioning can raise the risk of pressure sores because sensation may be reduced. Daily skin checks, pressure relief, and careful equipment fit can help prevent wounds and infections.
Inconsistent catheterization routines, low fluid intake, or delaying bladder care can increase urinary retention and infection risk. Good hydration and a reliable bladder program can help protect kidney function and reduce complications.
Risk prevention
Myelomeningocele is a birth condition that develops very early in pregnancy, so prevention focuses on lowering the chance of it happening rather than guaranteeing it can be avoided. The most effective step is getting enough folic acid before conception and during early pregnancy, because the spinal cord forms before many people know they are pregnant. Prevention isn’t about perfection, it’s about small steps that add up. Some cases still happen even when someone does everything recommended, but risk can often be reduced.
Taking folic acid every day before pregnancy and in the first weeks of pregnancy is the most important known way to lower the risk of myelomeningocele. For most people, this means 400 micrograms daily, while those with a prior neural tube defect pregnancy usually need a much higher dose prescribed by a clinician.
Because myelomeningocele begins very early, it helps to prepare before trying to conceive rather than waiting for a positive test. Many living with unplanned pregnancies may miss that early window, so a daily prenatal vitamin can be useful for anyone who could become pregnant.
Poorly controlled diabetes before and during early pregnancy can raise the risk of myelomeningocele and other birth differences. Keeping blood sugar in target range with medical guidance before conception can lower that risk.
Some medicines, especially certain anti-seizure drugs, can increase the risk of myelomeningocele. Reviewing all prescriptions, over-the-counter drugs, and supplements before pregnancy may allow safer options without stopping important treatment suddenly.
Can you prevent Myelomeningocele?
You cannot fully prevent myelomeningocele, which is a serious form of spina bifida, because it can still happen even when someone does everything right. But the risk can often be lowered by getting enough folic acid, a B vitamin, before pregnancy and in the first weeks of pregnancy, and by keeping diabetes well controlled before and early in pregnancy. These steps can reduce risk, but they do not guarantee prevention.
Transmission
Myelomeningocele is not infectious, so it cannot be caught from another person through touch, kissing, sex, food, or the air. When people ask about how myelomeningocele is inherited, the answer is that it usually is not passed down in a simple parent-to-child pattern like some single-gene conditions.
Many living with myelomeningocele were born with it because of a mix of genetic susceptibility and factors affecting very early pregnancy, and often there is no single clear cause. The genetic transmission of myelomeningocele is therefore considered complex rather than direct, but having one affected pregnancy can raise the chance in a future pregnancy, which is why genetic counseling and pre-pregnancy folic acid advice are often recommended.
When to test your genes
For myelomeningocele, genetic testing is usually not the main test for early detection; prenatal ultrasound and maternal blood screening are more useful. Gene testing may help if myelomeningocele happens with other birth differences, there is a family history, or you want clearer recurrence risk and pregnancy planning guidance.
Diagnosis
Myelomeningocele is often found before birth or recognized right after delivery because the changes in the lower back and spine are usually visible. Doctors usually begin with a physical exam and pregnancy or birth history, then use imaging tests to confirm what they are seeing. The diagnosis of myelomeningocele also includes checking for related problems, such as fluid buildup around the brain or bladder and bowel issues.
During pregnancy, ultrasound can often show an opening in the spine and a sac that contains nerves and spinal fluid. It may also show changes in the baby’s head shape or brain position that often happen with myelomeningocele.
A maternal blood test may show a higher-than-expected level of alpha-fetoprotein, also called AFP. This does not confirm myelomeningocele on its own, but it can be an important clue that leads to more detailed imaging.
If ultrasound suggests a spinal defect, fetal MRI may be used to look more closely at the spine, brain, and surrounding tissues. This can help confirm the diagnosis and support planning for delivery and early care.
After birth, many babies are diagnosed by examining the lower back and checking leg movement, reflexes, and the way the bladder and bowel may be affected. Some diagnoses are clear after a single visit, while others take more time.
How is Myelomeningocele diagnosed?
Myelomeningocele, a serious form of spina bifida, is often found before birth on a routine pregnancy ultrasound, and sometimes a blood test during pregnancy can raise concern for an opening in the baby’s spine; a fetal MRI may be used for a closer look. After birth, doctors can usually recognize it by examining the baby’s back and checking movement, feeling, and bladder or bowel function, then confirm it with imaging such as an ultrasound or MRI of the spine and brain. Genetic testing is not usually needed to make the diagnosis.
Stages of Myelomeningocele
Myelomeningocele does not have defined progression stages. That is because it is a birth defect present from the start, rather than an illness that typically moves step by step over time. Doctors usually find myelomeningocele during pregnancy with ultrasound and sometimes blood tests, or at birth by examining the spine and legs. After diagnosis, monitoring focuses on related problems such as movement, bladder and bowel control, hydrocephalus, and other early symptoms of myelomeningocele that can affect daily life as a child grows.
Outlook and prognosis
Outlook in myelomeningocele varies widely and depends on the level of the spinal lesion, the presence of hydrocephalus or Chiari II malformation, and complications affecting the bladder, kidneys, skin, and mobility. With modern neurosurgical care, shunting or endoscopic treatment when needed, rehabilitation, and careful urologic follow-up, many children survive into adulthood and can attend school, work, and live with varying degrees of independence. Long-term challenges commonly include lower-limb weakness or paralysis, bowel and bladder dysfunction, orthopedic problems, and a higher risk of learning or attention difficulties, especially when hydrocephalus is present. Mortality is highest in infancy and early childhood when severe brain abnormalities, infection, respiratory complications, or untreated hydrocephalus occur, but survival has improved substantially in high-resource settings. Over time, kidney disease from neurogenic bladder, shunt complications, pressure injuries, and obesity can affect health and quality of life, so lifelong multidisciplinary care is important. Overall, the prognosis for myelomeningocele is best when complications are recognized early and managed consistently across childhood and adult care.
Long-term effects
For many living with myelomeningocele, the long-term picture depends on where the spinal opening is and whether the brain and spinal fluid are also affected. Many grow into adulthood, but day-to-day life can include lasting changes in movement, bladder and bowel control, skin safety, and learning. Long-term effects vary widely, and some people need more medical support than others as they get older. When people ask about the long-term effects of myelomeningocele, doctors usually focus on mobility, nerve-related changes, and complications that can build up over time.
Weakness or paralysis in the legs can affect standing, walking, balance, and stamina over many years. Some people with myelomeningocele walk with braces or aids, while others use a wheelchair for part or all of daily life.
Nerve changes often make it hard to empty the bladder fully or control urine. Over time, this can raise the risk of urinary infections, kidney strain, and wetting accidents that affect school, work, or sleep.
Many people have long-term constipation, stool leakage, or trouble sensing when the bowel is full. This can make daily routines less predictable and may continue from childhood into adult life.
Some people with myelomeningocele also have extra fluid around the brain, called hydrocephalus, which may require a shunt. Long-term concerns can include headaches, vomiting, vision changes, or sudden changes in function if the shunt stops working properly.
How is it to live with Myelomeningocele?
Living with myelomeningocele can shape daily life in very practical ways: many people need ongoing routines for mobility, bladder and bowel care, skin protection, and regular medical visits, while also adapting to differences in strength, sensation, or learning that can vary widely from one person to another. For some, this means using braces, a wheelchair, or other supports, and planning ahead for school, work, travel, and accessibility so the day runs more smoothly. Family members and other close supporters often take on caregiving, advocacy, and coordination of care, which can be deeply meaningful but also tiring at times, so steady support, good equipment, and inclusive communities can make a real difference for everyone involved.
Treatment and drugs
Treatment for myelomeningocele usually starts early and often involves surgery to close the opening in the spine, sometimes before birth and more often soon after delivery, to help lower the risk of infection and protect the exposed nerves as much as possible. Even after surgery, many people with myelomeningocele need ongoing care for related problems such as leg weakness, bladder or bowel control issues, hydrocephalus, and skin breakdown. Doctors may prescribe medicines to help with bladder spasms, constipation, pain, or repeated urinary infections, and some people also need devices such as a shunt to drain extra fluid around the brain. Treatment plans often combine several approaches. For many, this can mean regular physical therapy, mobility aids, bladder and bowel programs, and follow-up with specialists over time, since the best treatment for myelomeningocele depends on age, symptoms, and how much the nerves were affected.
Can you cure Myelomeningocele?
No, myelomeningocele, a serious form of spina bifida, cannot be cured because the nerve damage is usually already there before birth. Surgery during pregnancy or soon after birth can close the opening in the back and help lower the risk of more damage, but it cannot undo harm that has already happened. Treatment focuses on helping children and adults stay as healthy and active as possible, including care for movement, bladder and bowel problems, fluid buildup in the brain, and skin or bone issues.
Non-drug treatment
Living with myelomeningocele often means managing mobility, bladder and bowel function, skin protection, and learning needs over time. Non-drug treatments often lay the foundation for staying as active, comfortable, and independent as possible. For many, treatment begins not at the pharmacy, but with rehabilitation, equipment, and daily routines that support school, work, and home life. Not every approach works the same way, so care is usually tailored to age, symptoms, and the level of the spinal opening.
Physical therapy helps build strength, improve balance, and make movement safer for people with myelomeningocele. It may include stretching to prevent tight joints and practice with sitting, standing, transfers, and walking. For many, this can mean easier movement from bed to wheelchair or safer steps with support.
Occupational therapy focuses on everyday tasks like dressing, bathing, handwriting, and using school or work tools. Therapists may also suggest simple ways to save energy and protect joints during daily routines. Supportive therapies can make home and classroom activities feel more manageable.
Braces, walkers, crutches, wheelchairs, and standing frames can improve mobility and help protect posture and bone health. The right equipment depends on muscle strength, balance, and whether someone can walk short or longer distances. Some may find that the best setup changes as they grow.
Many people with myelomeningocele need scheduled bathroom routines and clean intermittent catheterization to empty the bladder regularly. This can help lower the risk of leakage, kidney problems, and urinary infections. If you are looking into long-term care, bladder management for myelomeningocele is often a central part of daily treatment.
Your genes may have an impact on how drugs work for you
People living with myelomeningocele often take medicines for bladder problems, pain, muscle tightness, bowel issues, or sometimes seizures, and small inherited differences can affect how fast the body breaks down some of these drugs. For many, this can mean a usual dose works well, while for others the same dose may wear off too quickly, not help enough, or cause more side effects such as sleepiness, dizziness, or stomach upset. Genetic testing is not a routine part of care for myelomeningocele itself, but if medicines are not working as expected or side effects are a problem, doctors may sometimes consider whether inherited differences could be playing a role.
Pharmacological treatments
For many living with myelomeningocele, medicines do not repair the spinal opening itself, but they can help manage everyday problems linked to the condition. The drug plan depends on which body systems are affected, such as the bladder, bowel, muscles, skin, or brain. Medication is often just one chapter in care, alongside surgery, physical therapy, bladder programs, and regular follow-up. Common medications for myelomeningocele are chosen to ease symptoms and prevent complications rather than treat the underlying nerve changes.
Oxybutynin is one of the most commonly used medicines when myelomeningocele affects bladder control. It helps relax the bladder muscle, which can reduce leaking, lower pressure in the bladder, and help protect the kidneys.
Antibiotics such as trimethoprim-sulfamethoxazole, nitrofurantoin, cephalexin, or amoxicillin-clavulanate may be used to treat urinary tract infections. Some children or adults with repeated infections may also be prescribed a low daily antibiotic for prevention, although this is not needed for everyone.
Polyethylene glycol, lactulose, senna, or bisacodyl are often used when myelomeningocele causes constipation or trouble emptying the bowel. These medicines soften stool or stimulate bowel movements, which can make accidents, belly pain, and straining less common.
Acetaminophen or ibuprofen may help with mild pain after procedures or during flare-ups of muscle and joint strain. For nerve-related pain, doctors may use gabapentin or pregabalin, especially when medications for pain and bladder problems in myelomeningocele are both part of daily care.
Genetic influences
Genes can affect how the body handles folate and how the spine and nervous system form very early in pregnancy, so they may play a part in myelomeningocele. It’s natural to ask whether family history plays a role. In most families, though, there is not one single gene change to point to; instead, myelomeningocele is usually linked to a mix of inherited tendencies and other factors, such as low folate levels, diabetes, certain anti-seizure medicines, and obesity. This means most babies with myelomeningocele are born to parents with no known family history, but the chance of it happening again in a future pregnancy is higher than average after one affected pregnancy. If myelomeningocele has happened in your family, a doctor or genetic counselor can help explain recurrence risk and talk through steps that may lower the risk before a future pregnancy.
Is Myelomeningocele genetic?
Genetics can raise the chance of myelomeningocele, but it is usually not caused by a single gene change. Many small genetic differences, together with factors like low folate before and during early pregnancy, appear to play the biggest role.
Having a genetic risk is not necessarily a diagnosis
Gene variants are a normal part of human biology and are widely found in the general population. Most of these variants do not directly affect health and simply reflect natural human diversity. For many genes, carrying a variant connected to a condition suggests a possible link rather than a clear diagnosis, especially when several genes and environmental factors are involved. In some situations, though, a single well-studied variant in a specific gene can be enough to confirm a diagnosis.
Pharmacogenetics—how genetics influence drug effects
Many families ask whether genetics change the care plan for myelomeningocele, especially when surgeries, bladder medicines, or repeat procedures are involved. In most cases, genes help explain why myelomeningocele happened, but they do not yet point doctors to one standard medicine choice the way they do in a few other conditions. Not every difference in response is genetic, but a genetic diagnosis can matter if myelomeningocele is part of a broader syndrome, because that may change monitoring, the timing of surgery, and which treatments are safest to use. Day to day, treatment is usually guided more by the level of spinal involvement, extra fluid around the brain called hydrocephalus, bladder and bowel function, kidney health, and symptoms such as pain or muscle tightness than by a routine gene test. If you are wondering how genetics affect treatment for myelomeningocele, it can help to ask whether genetic testing is needed for the care plan itself or mainly to better understand the cause and future family risk.
Interactions with other conditions
For many living with myelomeningocele, health concerns do not happen one at a time, and a bladder infection, skin sore, or shunt problem can quickly affect how they feel day to day. Doctors call it a “comorbidity” when two conditions occur together, and myelomeningocele often overlaps with hydrocephalus, bladder and bowel problems, latex allergy, and weakness or stiffness in the legs. Some may also have scoliosis, hip problems, or kidney damage over time, especially if bladder function is hard to manage well. In children and adults with myelomeningocele, repeated urinary tract infections can raise the risk of kidney disease, while reduced sensation can make pressure injuries or wounds easier to miss. Seizures, sleep-disordered breathing, and learning or attention difficulties can also occur in some people, particularly when there are related brain or spinal cord changes. Because these issues can influence one another, it helps to have coordinated care so treatment for myelomeningocele and any other condition fits together safely.
How genes can cause diseases
Humans have more than 20,000 genes, each carrying out one or a few specific functions in the body. One gene instructs the body to digest lactose from milk, another tells the body how to build strong bones and another prevents the body's cells from beginning to multiply uncontrollably and developing into cancer. As all of these genes combined are the building instructions for our body, a defect in one of these genes can have severe health consequences.
Through decades of genetic research, we know the genetic code of any healthy/functional human gene. We have also identified that in certain positions on a gene, some individuals may have a different genetic letter from the one you have. We call these hotspots "Genetic Variations" or "Variants" in short. In many cases, studies have been able to show that having the genetic letter "G" in the position makes you healthy, but having the letter "A" in the same position disrupts the gene function and causes a disease. Genopedia allows you to view these variants in genes and summarizes all that we know from scientific research, which genetic letters (Genotype) have good or bad consequences on your health or on your traits.
What other conditions can cause similar symptoms to Myelomeningocele?
Some of the main conditions that can look similar are other forms of spina bifida, especially a less severe type called meningocele, and a tethered spinal cord, where the cord is abnormally attached and gets stretched as a child grows. A fatty lump connected to the spinal cord or, less often, other lower-spine problems can also cause leg weakness, foot changes, and trouble with bladder or bowel control. These conditions can overlap, so doctors usually tell them apart with a careful exam and spine imaging.
History
Families and communities once noticed patterns of babies born with an opening in the lower back, even though they had no medical words for what they were seeing. What we now call myelomeningocele, the most severe common form of spina bifida, has likely been present for as long as humans have existed. Earlier doctors described the visible spinal opening and the fluid-filled sac, but they did not yet understand why it happened or why some babies also had weakness in the legs, bladder problems, or fluid buildup in the brain.
By the 1800s and early 1900s, myelomeningocele was being described more clearly in medical writing. At that time, care was limited, and many babies did not survive infancy because of infection or related complications. For families, this often meant a frightening start to life, with few treatment options and little guidance about what to expect day to day.
Over time, surgery changed that picture. As anesthesia, sterile technique, and newborn care improved, doctors became better able to close the opening soon after birth and reduce the risk of infection. Later, treatment for hydrocephalus, which is extra fluid around the brain, also improved survival and helped many children living with myelomeningocele reach school age and adulthood.
As medical science evolved, attention shifted from survival alone to mobility, learning, bladder and bowel care, skin protection, and independence. This mattered in everyday life. A child who once might not have lived long enough to start school could now grow up needing coordinated care, physical therapy, braces or a wheelchair, and support with bladder routines, while still taking part in family life, school, and work.
Researchers later identified that myelomeningocele develops very early in pregnancy, when the spinal cord and surrounding tissues do not close in the usual way. That led to important public health steps, especially the recommendation for folic acid before and during early pregnancy, which has lowered the number of affected pregnancies in many countries. Even so, myelomeningocele still happens, and not all cases can be prevented.
In recent decades, care has become more specialized and more hopeful. Teams that include neurosurgeons, rehabilitation specialists, urologists, orthopedic doctors, and therapists now help many people with myelomeningocele live longer and fuller lives than in the past. This history also helps explain why early symptoms of myelomeningocele and related needs can vary so much from one child to another: the condition has been recognized for centuries, but understanding and treatment have steadily become more precise.
