Spina Bifida

Spina bifida is a congenital neural tube defect (NTD) characterized by the incomplete closure of the embryonic neural tube, typically affecting the lumbosacral spine. It ranges in severity from mild, asymptomatic spinal defects (spina bifida occulta) to severe herniation of the meninges and spinal cord (myelomeningocele), leading to permanent neurological and physical impairment.

Spina bifida is caused by a multifactorial interaction of genetic susceptibility and environmental factors. The primary environmental cause is maternal folate deficiency during early pregnancy. Other contributors include maternal diabetes, pre-pregnancy obesity, hyperthermia (e.g., fever, sauna use), and exposure to teratogenic medications such as valproic acid.

During the third and fourth weeks of embryonic development, the neural plate folds to form the neural tube (primary neurulation). Failure of the caudal neuropore to close by embryonic day 26 to 28 prevents the fusion of the overlying vertebral arches. At the cellular level, this disruption leads to exposed neuroepithelium, which undergoes progressive degeneration in utero due to exposure to amniotic fluid and mechanical trauma (the "two-hit" hypothesis).

The prevalence of spina bifida is approximately 3 per 10,000 live births in the United States. It shows a higher incidence in Hispanic populations. There is a slight female predominance.

• Maternal folate deficiency
• Family history of neural tube defects
• Maternal pregestational diabetes
• Maternal obesity (BMI $\ge$ 30)
• First-trimester exposure to anti-seizure medications (valproate, carbamazepine)
• Maternal hyperthermia in early pregnancy

• Inspection: Midline lumbosacral skin defects (sac, lipoma, dimple, hypertrichosis, hemangioma).
• Neurological: Flaccid paralysis of lower extremities, sensory level corresponding to the spinal lesion, diminished or absent deep tendon reflexes.
• Musculoskeletal: Hip dislocation, clubfoot (talipes equinovarus), or joint contractures.
• Head: Enlarged head circumference (macrocephaly) and bulging anterior fontanelle in infants with associated hydrocephalus.

Maternal Serum Alpha-Fetoprotein (MSAFP) Type: Blood Test

• Purpose: Prenatal screening for open neural tube defects.


• Expected Findings: Elevated levels of MSAFP at 15–20 weeks gestation.


• Interpretation: High MSAFP indicates a high risk of open spina bifida, requiring confirmatory amniocentesis or high-resolution ultrasound.

• Purpose: Confirmatory prenatal diagnosis of open NTDs.


• Expected Findings: Elevated AFAFP and presence of acetylcholinesterase (AChE).


• Interpretation: Diagnostic for open neural tube defects.

Obstetrical Ultrasound (Fetal) Purpose: Screening and prenatal diagnosis.

• Typical Findings: "Lemon sign" (scalloping of frontal bones), "banana sign" (curved cerebellum in Chiari II), and visible spinal bony defects.


• Clinical Importance: Guides prenatal counseling and delivery planning (e.g., cesarean delivery or fetal surgery).

• Typical Findings: Ventriculomegaly, Chiari II malformation, tethered spinal cord, or syrinx.


• Clinical Importance: Guides surgical intervention (shunt placement, cord untethering).

• Sacrococcygeal Teratoma: Distinguished by a solid/cystic tumor mass originating from the coccyx without spinal canal dysraphism.
• Caudal Regression Syndrome: Characterized by sacral agenesis and lower limb deformities, but without an open dural sac or meningeal protrusion.
• Spinal Muscular Atrophy (SMA): Genetic motor neuron degeneration causing hypotonia without structural vertebral defects.

• Hydrocephalus and shunt failure
• Neurogenic bladder leading to chronic kidney disease
• Decubitus ulcers and osteomyelitis
• Latex allergy (highly prevalent due to frequent exposures)
• Scoliosis and joint contractures
• Tethered spinal cord syndrome

Long-term survival for infants with spina bifida has improved to over 90% with modern surgical and medical care. Physical disability is typically permanent, but most individuals have normal intelligence and can achieve independent living with appropriate medical, orthopedic, and urological management.

• Daily consumption of 0.4 mg (400 mcg) of folic acid by all individuals of childbearing potential.
• Prenatal screening and ultrasound evaluation.
