In more severe forms, the spinal cord and coverings protrude through the opening, which means that nerve damage occurs. There is no cure for spina bifida. There is no opening on the back, but the outer part of some of the vertebrae are not completely closed. There may be hair or a dimple at the site. The outer part of some of the vertebrae are split and the meninges are damaged and pushed out through the opening, appearing as a sac.
Cerebrospinal fluid is in the sac.

The outer part of some of the vertebrae are split, and the spinal cord and meninges are damaged and pushed out through the opening. This causes nerve damage and almost always some degree of paralysis.
