spina bifida spina bifida spina bif·i·da (bĭf'ĭ-də) n. A congenital defect in which the spinal column is imperfectly closed so that part of the meninges or spinal cord may protrude, often resulting in neurological disorders.

- Characteristics. The effects of myelomeningocele, the most serious form of spina bifida, may include muscle weakness or paralysis below the area of the spine where the incomplete closure (or cleft) occurs, loss of sensation below the cleft, and loss of bowel and bladder control.pina Bifida means cleft spine, which is an incomplete closure in the spinal column. In general, the three types of spina bifida (from mild to severe) are: 1  Spina Bifida Occulta: There is an opening in one or more of the vertebrae (bones) of the spinal column without apparent damage to the spinal cord.

Spina bifida Myelomeningocele, also known as open spina bifida, is the most severe form. Associated problems include poor ability to walk, problems with bladder or bowel control, hydrocephalus, a tethered spinal cord, and latex allergy.

Spina Bifida Spina Bifida Overview. Spina bifida (“cleft spine”) is a birth defect affecting the spinal column. Spina bifida progresses from a cleft, or splitlike opening, in the back part of the backbones (the spinal vertebrae). In more severe cases, it involves the spinal cord.pina Bifida Overview.

Overview Spina bifida. Doctors aren't certain what causes spina bifida. As with many other problems, it appears to result from a combination of genetic and environmental risk factors, such as a family history of neural tube defects and folic acid deficiency.

- Spina bifida (Latin : split spine) is a birth defect where there is incomplete closing of the backbone and membranes around the spinal cord. There are three main types: spina bifida occulta, meningocele, and myelomeningocele.

Spina bifida Neural tube defects (NTDs) are among the most common birth defects contributing to infant mortality and serious disability. NTDs, which include anencephaly, spina bifida, and encephalocele, occur in approximately 1 of 1000 births in the United States. An estimated 4000 pregnancies are affected with NTDs each year.

What is spina bifida? Spina bifida is a birth defect in which an area of the spinal column doesn’t form properly, leaving a section of the spinal cord and spinal nerves exposed through an opening in the back. Myelomeningocele (MMC), the most common and serious form of spina bifida, may be treated before birth with fetal surgery.

Spina Bifida and Genetics Spina bifida is the most common neural tube birth defect in the United States. At the present time the causes of spina bifida are unknown, though it is strongly believed that both genetics and the environment are contributing factors.

spina bifida occulta spina bifida in which there is protrusion through the defect of a cystic swelling involving the meninges (meningocele), spinal cord (myelocele) or both (meningomyelocele). spina bifida occulta. spina bifida in which there is a defect of the bony spinal canal without protrusion of the cord or meninges. spina bifida ventralis. a defect of closure on the ventral surface of the bony spinal canal, often associated with defective development of the abdominal and thoracic viscera.

Myelomeningocele Myelomeningocele is the most common type of spina bifida. It is a neural tube defect in which the bones of the spine do not completely form, resulting in an incomplete spinal canal. This causes the spinal cord and meninges (the tissues covering the spinal cord) to stick out of the child's back. Myelomeningocele may affect as many as 1 out of every 800 infants.

meningomyelocele Protrusion of the spinal meninges and cord through a defect of the vertebral column, usually at the distal end; when accompanied by a bone defect, it is termed spina bifida. 1:5000 births. Often accompanied by midline defects—e.g., of the anus, heart and trachea (tracheo-oesophageal fistulas). meningomyelocele.

Meningomyelocele and Spina Bifida Spina bifida is a neural tube defect-a type of birth defect of the brain, spine, or spinal cord. It happens if the spinal column of the fetus doesn't close completely during the first month of pregnancy.

- 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.

- Myelomeningocele (my-uh-low-meh-NIN-guh-seel) is the most severe form of spina bifida. It happens when both the meninges and the bottom end of the spinal cord push through the hole in the spine, forming a large fluid-filled sac that bulges out of a baby's back.

Myelomeningocele 1 Spina bifida occulta, a condition in which the bones of the spine do not close but the spinal cord and meninges remain in place and skin usually covers the defect. 2  Meningoceles, a condition where the tissue covering the spinal cord sticks out of the spinal defect but the spinal cord remains in place.

What Is Spina Bifida? This type of spina bifida doesn't typically cause any type of disability. Meningocele: This rare type of spina bifida happens when a sac of spinal fluid (but not the spinal cord) pushes through an opening in the baby's back. Some people have few or no symptoms, while others have problems with their bladder and bowels.

Making Sense of Sandpaper Don't skip grits, usually--Skipping a grit to save time and sandpaper is a common temptation, but not a good idea when working with hardwoods. You can remove the scratches left by 120-grit sandpaper with 180-grit, but it will take you far more work than if you use 150-grit first.

Basics Spina bifida is a condition that affects the spine and is usually apparent at birth. It is a type of neural tube defect (NTD). Spina bifida can happen anywhere along the spine if the neural tube does not close all the way. The backbone that protects the spinal cord does not form and close as it should.ith meningocele a sac of fluid comes through an opening in the baby’s back. But, the spinal cord is not in this sac. There is usually little or no nerve damage. This type of spina bifida can cause minor disabilities.

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 and SSA Disability There are four types of spina bifida: occulta, closed neural tube defects, meningocele, and myelomeningocele. Occulta is the mildest and most common form in which one or more vertebrae are malformed.losed neural tube defects make up the second type of spina bifida. This form consists of a diverse group of defects in which the spinal cord is marked by malformations of fat, bone, or meninges.

Spina bifida Physical signs of spina bifida may include: 1  Leg weakness and paralysis. 2  Orthopedic abnormalities (i.e., club foot, hip dislocation, scoliosis) 3  Bladder and bowel control problems, including incontinence, urinary tract infections, and poor kidney function. 4  Pressure sores and skin irritations. 5  Abnormal eye movement.

- Scientists suspect the factors that cause spina bifida are multiple: genetic, nutritional, and environmental factors all play a role. Research studies indicate that insufficient intake of folic acid—a common B vitamin—in the mother’s diet is a key factor in causing spina bifida and other neural tube defects.

Spina Bifida Signs and Symptoms Symptoms of spina bifida depend on the type of the disease and how severely the spinal cord and surrounding nerves are affected. Occulta is the mildest form of the disease. Vertebrae are malformed but the spinal cord and its covering are undamaged. The condition typically doesn't cause disability or symptoms.

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.
