What is Spina Bifida Occulta?
Neural arches of L5 and/or S1 fail to develop normally and fuse posterior to the vertebral canal.
Defect is usually concealed by the overlying skin but its location is often indicated by a tuft of air.
Most people have no back problems
What is Spina Bifida Cystica?
In more severe cases of Spina Bifida, one or more of the vertebral arches may fail to develop completely.
Associated with herniation of the meninges and/or of the spinal cord.
Neurological symptoms are usually present in severe cases e.b. Paralysis of the limbs and disturbance in bladder and bowel control.
Severe forms of Spina Bifida result from neural tube defects such as the defective closure of the neural tube during the 4th week of embryonic development
