Spina bifida

Spina bifida describes birth defects caused by an incomplete closure of one or more vertebral arches of the spine, resulting in malformations of the spinal cord. The spinal membranes and spinal cord may protrude through the absence of vertebral arches (called a cleft). These malformations fall into three categories: spina bifida occulta, spina bifida cystica (myelomeningocele) and meningocele.
