Spina bifida aperta

• Besides absence of the bone structure, there is an abnormality with the meningocele. (this is the layer of tissue that surrounds the spinal cord)

• Mildest form – protrusion of the meninges under the skin through the cleft in the vertebral arch (pink)

Spina bifida aperta (myelomeningocele)

Spina bifida aperta (myeloschisis)
