a congenital defect of the central nervous system in which a sac containing part of the spinal cord and its meninges protrude through a gap in the vertebral column; frequently accompanied by hydrocephalus and mental retardation
a congenital deformity of the spine characterized by an opening allowing the protrusion of the spinal cord. The condition is generally associated with an abnormality of the spinal cord as well. Also known as spina bifida.
A protrusion of the spinal cord and its encasing membrane through an opening in the bony spinal column, resulting in damage to the spinal cord. Occurs during fetal development and is often a factor in spinal bifida.
A congenital abnormality where the spinal cord does not roll up into a tube the way that it normally does. The spinal cordstays on the surface of the skin. The nerves that are below the level where the spinal cord stopped rolling up do not work properly.
An "open spine" is a protrusion of the meninges, spinal cord and nerves out of an opening in the vertebral column. Skin, or a thin membrane may cover this spinal cord defect. Known also as spina bifida.
