Part of the spine is open at birthSpina bifida occurs when the fetus is growing in the womb and its spine doesn't form correctly (a neural tube defect). Some of the vertebrae (bones in the spine) don't close to make their normal ring shapes around the spinal cord. The opening that results causes one of three types of spina bifida: - Spina bifida occulta: a tiny opening, usually causes mild or no symptoms
- Spina bifida cystica - meningocele: a big enough opening so that some of the membrane surrounding the spinal cord sticks out through the opening
- Spina bifida cystica - myelomeningocele: the most serious kind, in which some of the spinal cord itself sticks out through the opening in the spine.
What type of symptoms the person has depends on where along the spine the opening occurred, since that is where the spinal cord was injured.
