Spina bifida (SB; /ˌspaɪnə ˈbɪfɪdə/, [9] Latin for 'split spine') [10] is a birth defect in which there is incomplete closing of the spine and the membranes around the spinal cord during early development in pregnancy. [1] There are three main types: spina bifida occulta, meningocele and myelomeningocele. [1]
Spina bifida, or myelomeningocele, is a type of open neural tube defect that can occur with problems with the early development of a fetus. Most researchers believe that both genetic and environmental factors (such as diet) play a role. During the first 28 days of a pregnancy, the brain and spinal cord form in the developing fetus.
Spina bifida is further divided into two subclasses, spina bifida cystica and spina bifida occulta. [18] Spina bifida cystica includes meningocele and myelomeningocele. Meningocele is less severe and is characterized by herniation of the meninges, but not the spinal cord, through the opening in the spinal canal.
Spina bifida is a birth defect that affects the lowest part of the spine and occurs when a fetus's neural tube does not fully close, causing the backbone that protects the spinal cord not to form ...
After birth, exposure of the spinal cord to the outside environment (myelomeningocele or spina bifida) is associated with several morbidities including weakness or sensory defecits in the lower extremities, bladder dysfunction, fluid buildup in the brain and Type 2 Chiari malformations (herniation of the cerebellar vermis and medulla from the ...
Spina bifida is the most common defect impacting the Central Nervous System (CNS). The most common and most severe form of Spina Bifida is Myelomeningocele. Individuals with Myelomeningocele are born with an incompletely fused spine, and therefore exposing the spinal cord through an opening in the back.
In tethered spinal cord cases spina bifida can be accompanied by tethering of the spinal cord but in rare cases with Spina bifida occulta. Tethering of the spinal cord tends to occur in the cases of Spina bifida with mylomeningocele. In most people the spine grows faster than the spinal cord during development which causes the end of the spinal ...
English: An ultrasound visualisation of the spine of a foetus at 21 weeks of pregnancy. The foetus is affected by open spina bifida (spina bifida cystica). In the centre of this longitudinal scan a lumbar myelomeningocele appears as dome shaped structure attached to the lumbar region of the foetal spine.
