Definition: Type of spina bifida in which the spinal cord and the meninges protrude from an opening in the spine.
A myelomeningocele is the most common type of spina bifida and is characterized by herniation of the spinal cord, nerves, or both through a bony defect of the spine. Myelomeningoceles are usually open defects in which either meninges or neural tissue is exposed to the environment.
