Spina bifida

Also called Myelomeningocele or Neural tube defect

Spina bifida is when a baby's spine and spinal cord do not develop properly in the womb, leaving a gap in the spine. It is a type of neural tube defect. Its effects range from none at all to weakness or paralysis of the legs, bladder and bowel problems and a build-up of fluid on the brain (hydrocephalus). Taking folic acid before and in early pregnancy lowers the risk.

What it is

It is usually found at the 20-week pregnancy scan. Some babies have surgery to close the gap in the spine before or soon after birth.

Lifelong care from a team of specialists may be needed, including physiotherapy, help with bladder and bowel, and treatment for hydrocephalus.
