Spina bifida is the most common neural tube defect. Between 1,500 and 2,000 babies born in the United States are affected each year. There are an estimated 166,000 people living with spina bifida in the U.S.
Spina bifida is a birth defect that occurs when the neural tube (a layer of cells that develops into the brain and spinal cord) fails to close completely during an embryo’s first few weeks of development. As the bones of the spine and the nerves of the spinal cord continue to develop, the bones do not close completely around the nerves. Part of the spinal cord may stick out through an opening in the bones, causing permanent nerve damage.
There are four types of spina bifida:
Spina bifida occulta is the mildest and most common form of the condition. Children born with occulta have one or more malformed vertebrae. This form of spina bifida occurs in 10 to 20 percent of the general population and rarely causes disability or symptoms.
Closed neural tube defects are a group of defects where the spinal cord shows malformations of fat, bone or meninges. In most cases, children have few or no symptoms. In some cases, the disorder can cause incomplete paralysis with urinary and bowel dysfunction.
Meningocele happens when spinal fluid and meninges poke through an abnormal opening in the vertebrae. The malformation does not contain neural elements and may or may not be covered by a layer of skin. Some children with meningocele have few or no symptoms. Others may experience complete paralysis with bladder and bowel dysfunction.
Myelomeningocele is the most severe form of spina bifida. In babies with myelomeningocele, the spinal cord and surrounding structures develop outside the body and are contained in a fluid-filled sac or lesion that is visible on the outside of the baby’s back. The sac is usually located on the lower back, and babies lose function below the area where the defect is located. If the sac is located higher up on a baby’s back, more areas will lose function
Effects of Myelomeningocele
The number and severity of problems in children with myelomeningocele can vary depending on where the sac is located on the spine and how much of the spinal cord is affected. Possible health effects of myelomeningocele include:
Doctors at Riley at IU Health can diagnose spina bifida before birth through:
Since doctors know in advance that you and your baby will require specialized care during and after delivery, you will begin working with a multidisciplinary care team upon diagnosis to develop a plan for your baby’s birth and treatment.
You may have to deliver the baby by cesarean section (C-section) to reduce the risk of injury. In the delivery room, your baby will be placed in a special bag to lower the risk of infection. From the delivery room, your baby will be moved to the neonatal intensive care unit (NICU) for evaluation. If you deliver your baby at Riley at IU Health, he or she will receive specialized multidisciplinary treatment from the Spina Bifida Program.
A neurosurgeon will examine your baby shortly after birth to evaluate the severity of the defect and develop a treatment plan. Many babies with myelomeningocele have hydrocephalus (a build-up of fluid and pressure in the brain). If this is the case, your baby will have a special drain called a shunt placed to drain the fluid. Not all babies with myelomeningocele will need a shunt.
While in the NICU at Riley at IU Health, all babies with myelomeningocele will also have a urinary catheter inserted to help empty the bladder. Depending on the severity of the defect, this may be temporary or long-term.
A neurosurgeon will perform surgery to correct the defect within the first two days after birth. Along with surgery to repair the spinal defect, your baby may also require additional procedures later on to address orthopedic issues and problems with the bowel or bladder.
Learning your child will have spina bifida can seem overwhelming. Riley at IU Health has created answers to some of the Frequently Asked Questions our families ask.
Will I see my baby after he or she is born? Can I hold?
Whether you are able to hold your baby after birth depends on if the opening in your baby’s back is covered by skin or open. If it is open, special care must be done to protect the spinal cord from damage and to lower the risk of infection. Your baby will be gently cleaned, and the area of the back that is affected will be covered and protected immediately after birth. You will be able to have contact with your baby before he or she is transported to the Newborn Intensive Care Unit (NICU).
Can I breast feed my baby with spina bifida?
We do everything possible to encourage breast feeding. However, depending on the needs of your baby we may need you to provide pumped breast milk to promote healthy feeding for the baby. Our lactation consultants will work with you if you are interested.
How long will the baby be in the hospital after birth?
Every baby born with spina bifida is unique and has individual needs. But, on average babies will be in the NICU for about two weeks.
How many surgeries will my baby need?
Every baby is unique and we treat their needs as needed. Most of the early procedures are for the spina cord and brain. If the hole in the back is covered by skin, the surgery may be delayed depending on what your neurosurgery team feels is best. If open, it will be closed within the first 24-72 hours of life. About eight out of 10 babies with spina bifida will need closure of the back, and a tube (shunt) placed in the brain to drain the fluid (hydrocephalus). About 40-50% will need to have the shunt replaced during the first year of life.
If we want to have more children, what is my risk of having another baby born with spina bifida and can I do anything to lessen the risk?
Your OB/GYN and spina bifida team will recommend that you be on 4 mg of folic acid three to six months before your conceive your next child. While not perfect, it greatly reduces the risk of another baby having spina bifida.
Can I deliver my baby at my local hospital?
Babies with spina bifida should be delivered at a medical center that specializes in spina bifida so they can receive specialty care during after birth. By receiving care at a medical center specializing in spina bifida, it will be easier for the baby to have the best possible outcome. The Fetal Center at Riley at IU Health is equipped to deliver babies born with spina bifida.
Can I visit the NICU before delivery so I can better prepare?
Our NICU staff will be happy to give you and your family a tour of the NICU at Riley at IU Health so that you will see where your baby will be cared for and to learn more about the NICU. They will give you the basic information of the NICU such as:
What should I pack for my baby’s NICU stay?
We will supply diapers, breastmilk pump, formula (if needed), clothes and all medical supplies. You may want to bring personal items to decorate your baby’s NICU room. Please write your name on all things you bring to the NICU. The only necessary items to eventually bring for your baby are something to wear home and a car seat.
What specialists will treat my baby in the NICU?
Make sure you know who everyone is before they touch your baby. There will be many members of the care team involved in your baby's treatment. These may include:
This can be overwhelming and confusing until you figure out who makes decisions and is the best to answer your questions.
Can you tell me more about the people caring for my baby?
As you can see it takes many care team members to help manage your baby’s spina bifida. Here are the main care team leaders:
How do I know that we are ready to go home?
We will want to make sure that the surgical site is healing well, your baby is eating and gaining weight, is able to keep their body temperature at a normal range and is healthy enough to go home. The urologist will review all of the necessary urologic tests to ensure that the baby is emptying their bladder well on their own or the parent/care giver is able to help the baby empty their bladder by a catheter. The neurosurgeon will make sure the back is healing well and that the hydrocephalus is stable (either with or without a shunt). All babies will receive a hearing test and newborn screen to rule out other medical conditions. Most babies can go home in a regular rear-facing infant car safety seat but if that is not possible, a specially designed baby car bed will be provided. At discharge, the social worker or nurse will help set up follow up appointments with the specialists and Spina Bifida Program.
What is it like to bring my baby home?
Parents spend the entire NICU stay learning how to care for their baby and looking forward to bringing their baby home. But when discharge day arrives, their excitement and relief can also be mixed with anxiety. For the first time, there won’t be round-the-clock healthcare providers to care for your baby, answer your questions and calm any fears. First-time parents realize (as all first-time parents do) that they will be solely responsible for caring for their baby, and those with other children at home worry about how they will care for the new baby along with their other children. These are all very normal fears.
The first day home will hopefully feel like a huge relief. You made it through the hardest parts of having a baby with Spina Bifida—the pregnancy and the NICU.
Coming home can also be a big adjustment. There will be people to call, appointments to make, prescriptions to fill, diapers to change and a schedule to keep. Many parents say one benefit of their baby being in the NICU is that he or she is already on a three-hour feeding schedule, which is often maintained at home. Friends and family may be eager to visit you and the baby during the first few days at home, but you should protect your time as best as possible so that you can rest and begin recovering physically and emotionally from what can be a stressful experience.
