Overview Spina bifida is part of a group of birth defects called neural tube defects. The neural tube is the embryonic structure that eventually develops into the baby's brain and spinal cord and the tissues that enclose them. Normally, the neural tube forms early in the pregnancy and closes by the 28th day after conception. In babies with spina bifida, a portion of the neural tube fails to develop or close properly, causing defects in the spinal cord and in the bones of the spine.

Myelomeningocele (Spina Bifida) Fetal Repair Myelomeningocele, a type of “open spina bifida,” is the most serious form of the disease. In myelomeningocele, a portion of the baby’s spinal cord and surrounding nerves protrude through an opening in the spine into an exposed, flat disc or sac that is visible on the back. This exposes the baby’s spinal cord to the amniotic fluid in the mother’s womb and can be harmful to the baby’s fetal development.

Medical Definition of Spina bifida occulta Spina bifida occulta: A bony defect in the vertebral column that causes a cleft in that column. The cleft remains covered by skin. Treatment is usually not required.

Spina bifida Spina bifida with myeloschisis is the most severe form of myelomeningocele. In this type, the involved area is represented by a flattened, plate-like mass of nervous tissue with no overlying membrane. The exposure of these nerves and tissues make the baby more prone to life-threatening infections such as meningitis.

What is Spina Bifida (Myelomeningocele)? Spina bifida is a congenital defect consisting of an opening in the spinal column. The most severe form is called myelomeningocele. Most children with this birth defect survive, but they can be left with many disabilities, including paralysis, difficulty with bowel and bladder control, a Chiari II malformation, hydrocephalus (excessive fluid in the brain), and developmental delay.

Spina Bifida Spina bifida cystica causes a problem when the meningeal cyst (meningocele) includes cord tissue extending into the cyst (in which case, it is a myelomeningocele). The condition is also of particular concern when the neural tube is completely open and the ependymal layer is exposed as a myelocele (or myeloschisis).

Spina bifida Spina bifida is the most common kind of neural tube defect (also called NTD). NTDs are birth defects of the brain and spinal cord. Birth defects are health conditions that are present at birth. Birth defects change the shape or function of one or more parts of the body. Surgery can remove the meningocele. 2  Myelomeningocele (also called open spina bifida). 3  This is the most severe and the most common form of spina bifida. 4  In this condition, part of the spinal cord pushes out with the meninges through the gap in the spine to form a sac on the baby’s back.

- A baby with this type of spina bifida usually has some paralysis, and muscle or bone problems as a result of the paralysis. This is due to the abnormal development of nerves in the spine, or to nerves being stretched as a result of the defect.

Spina Bifida (Neural Tube Defect) Spina bifida is among a group of birth defects called neural tube defects. When the fetus is developing, its central nervous system begins as a tube early in its life that eventually forms the brain, spinal cord, and the surrounding tissues. By the fetus' 28th day of life, this tube should be closed.

- Two major types of neural tube defects, spina bifida and anencephaly, are birth defects that. affect thousands of babies every year in the United States. ➤ Neural tube defects (NTDs) are birth defects that occur when the embryonic neural. tube, which ultimately forms the spinal cord and the brain, does not close properly. Anencephaly — the absence of the brain — is a fatal condition that occurs when the. upper end of the neural tube fails to close.

Spina Bifida What Is Spina Bifida? Spina bifida is a group of congenital disabilities (a disability that is present at birth) that affects the spine. A baby who has the most severe form of spina bifida will be born with part of the spinal cord outside the body. Mild spina bifida might not cause symptoms.

spina bifida A congenital defect in which the spinal column is imperfectly closed so that part of the meninges or spinal cord protrudes, often resulting in hydrocephalus and other neurological disorders. [New Latin spīna bifida : Latin spīna, spine + Latin bifida, feminine of bifidus, split in two.]

Basics Spina bifida occulta is the mildest type of spina bifida. It is sometimes called “hidden” spina bifida. With it, there is a small gap in the spine, but no opening or sac on the back. The spinal cord and the nerves usually are normal. Many times, spina bifida occulta is not discovered until late childhood or adulthood.

- Types of Spina Bifida. The two forms of spina bifida are spina bifida occulta and spina bifida aperta: Spina bifida occulta is the mildest form of the condition and can go unnoticed. Occulta means hidden in Latin, which in this case means that the defect is covered by skin.

Spina Bifida In Children Spina bifida is a neural tube birth defect that prevents your child's vertebrae from forming correctly. The nerves in your child's spinal cord may be exposed, or form outside his vertebrae or skin. There are several types of spina bifida. Each type may affect your child in a different way.

What is spina bifida? Spina bifida cystica occurs when the lining (membranes) of the spinal cord and sometimes the spinal cord push out through the defect in the spine. The two main types of spina bifida cystica are called meningocele and myelomeningocele: Meningocele. Spina bifida meningocele is the rarest type of spina bifida. The protective membranes (the meninges) surrounding the spinal cord are pushed out between openings in the vertebrae. The meningocele is sometimes covered by a layer of skin.

What you need to know about spina bifida Knowledge center. Spina bifida is a congenital malformation in which there is something wrong with the bone in the vertebral column, exposing the spinal cord which should be protected within the vertebral column. It is caused by the incomplete closing of the embryonic neural tube. Congenital malformation means a birth defect.

Spina Bifida - Topic Overview What is spina bifida?Spina bifida is a type of birth defect called a neural tube defect. It occurs when the bones of the spine (vertebrae) don't form properly around part of the baby's spinal cord. Spina bifida can be mild or severe. The mild form is the most common. It usually doesn't cause problems or need treatment.
