Spina Bifida

Spina bifida is a neural tube defect that occurs during early pregnancy when the spine and spinal cord fail to develop properly. This congenital condition affects approximately 1 in 2,000 births and can range from mild, barely noticeable forms to severe conditions that significantly impact mobility and organ function. Understanding spina bifida, its various forms, and comprehensive management approaches is essential for families and healthcare providers to optimize outcomes and quality of life for affected individuals.

Overview

Spina bifida, literally meaning "split spine," is a birth defect that occurs when the neural tube fails to close completely during the first month of pregnancy. The neural tube is the embryonic structure that eventually develops into the brain and spinal cord. When this tube doesn't close properly, it results in defects in the spine and, in more severe cases, the spinal cord itself.

This condition is part of a group of birth defects called neural tube defects (NTDs). The severity of spina bifida varies greatly, from forms so mild they may go unnoticed throughout life to severe forms that cause significant physical and intellectual disabilities. The location of the spinal defect also influences the extent of symptoms and functional limitations.

Spina bifida is a permanent condition, but with proper medical care, educational support, and assistive technologies, many individuals with spina bifida can lead full, productive lives. Early intervention and comprehensive care teams play crucial roles in optimizing outcomes and helping individuals reach their full potential.

Types of Spina Bifida

  • Spina Bifida Occulta: The mildest form, where the opening in the spine is covered by skin
  • Meningocele: The spinal fluid and meninges protrude through the opening, but the spinal cord remains in place
  • Myelomeningocele: The most severe form, where the spinal cord and meninges protrude through the opening
  • Lipomyelomeningocele: A fatty tumor attached to the spinal cord causes the defect

Symptoms

The symptoms of spina bifida vary dramatically depending on the type and location of the defect. Some individuals may have no symptoms at all, while others may experience significant physical and neurological challenges.

Spina Bifida Occulta

Often the mildest form, symptoms may include:

Causes

The exact cause of spina bifida remains unknown, but research suggests it results from a combination of genetic and environmental factors during early pregnancy. Understanding these factors helps in prevention efforts and genetic counseling.

Neural Tube Development

During the first month of pregnancy, the neural tube forms and closes to create the brain and spinal cord. In spina bifida, this closure process is interrupted, typically between the 17th and 30th day after conception. The precise mechanism of this failure is complex and multifactorial.

Genetic Factors

Family History

  • Previous affected child: 2-5% recurrence risk
  • Affected parent: 3-4% risk of having affected child
  • Sibling with NTD: Increased risk for subsequent pregnancies
  • Consanguinity: Higher risk in related parents

Chromosomal and Genetic Syndromes

  • Trisomy 13, 18: Associated chromosomal abnormalities
  • MTHFR mutations: Affecting folate metabolism
  • Single gene defects: Rare genetic causes

Multifactorial Inheritance

Spina bifida follows a multifactorial inheritance pattern, meaning:

  • Multiple genes contribute to susceptibility
  • Environmental factors interact with genetic predisposition
  • Threshold effect - accumulation of risk factors
  • Variable expression even within families
  • Both parents contribute to genetic risk

Frequently Asked Questions

What causes spina bifida?

Spina bifida is caused by incomplete closure of the neural tube during early pregnancy (17-30 days after conception). The exact cause is unknown, but it involves a combination of genetic factors and environmental influences, particularly folate deficiency. Other risk factors include diabetes, obesity, certain medications, and family history.

Can spina bifida be prevented?

Yes, up to 70% of spina bifida cases can be prevented by taking folic acid supplements. All women of reproductive age should take 400-800 mcg of folic acid daily, starting before conception. Women at high risk may need higher doses (4-5 mg daily) under medical supervision.

Will my child with spina bifida be able to walk?

Walking ability depends on the level and severity of the spinal defect. Children with lower lumbar or sacral level defects often walk independently or with minimal assistance. Those with higher level defects may use wheelchairs for mobility but can still lead active, independent lives with proper support and adaptive equipment.

What is the life expectancy for someone with spina bifida?

With modern medical care, most people with spina bifida have a normal or near-normal life expectancy. Early intervention, comprehensive medical care, and prevention of complications are key factors. The majority of children with spina bifida survive to adulthood and can lead fulfilling lives.

Can people with spina bifida have children?

Yes, many people with spina bifida can have children. Fertility may be affected in some cases, particularly in men with higher-level lesions. Women with spina bifida can usually conceive and carry pregnancies to term, though they need specialized prenatal care and may require cesarean delivery.

What is hydrocephalus and why is it common with spina bifida?

Hydrocephalus is the accumulation of cerebrospinal fluid in the brain, occurring in 80-90% of children with myelomeningocele. It's often associated with Chiari II malformation, which blocks normal fluid flow. Treatment typically involves placing a shunt to drain excess fluid from the brain to another part of the body.

How is bladder and bowel function affected?

Most people with myelomeningocele have neurogenic bladder and bowel, meaning the nerves controlling these functions are affected. This can lead to incontinence, urinary tract infections, and kidney problems. Management includes intermittent catheterization, medications, and sometimes surgery to protect kidney function.

What educational support do children with spina bifida need?

Educational needs vary widely. Many children with spina bifida have normal intelligence, while others may have learning differences or intellectual disabilities. Most benefit from early intervention services and may need special education support, assistive technology, or accommodations for physical access and medical needs.

Is spina bifida genetic?

Spina bifida has a genetic component but follows a complex, multifactorial inheritance pattern. Having one child with spina bifida increases the risk for future pregnancies by 2-5%. The condition can also occur in families with no previous history. Genetic counseling can help assess individual risks.

What is fetal surgery for spina bifida?

Fetal surgery involves repairing the spinal defect before birth, typically performed between 19-26 weeks of pregnancy. Studies show it can reduce the need for shunt placement and improve motor function, but it carries risks including premature delivery. Candidates are carefully selected based on specific criteria.
