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]
Vertebral abnormalities. [14] On rare occasions, brachial plexus irritation can occur. [10] Scoliosis, spina bifida and syringomyelia have also been described. [10] Wide nasal bridge; Crooked teeth; Increased risk of flat foot and knee deformities; High risk of hearing loss caused by infections; Decreased bone density, resulting in increased ...
Screening can detect problems such as neural tube defects, chromosome abnormalities, and gene mutations that would lead to genetic disorders and birth defects such as spina bifida, cleft palate, Down syndrome, trisomy 18, Tay–Sachs disease, sickle cell anemia, thalassemia, cystic fibrosis, muscular dystrophy, and fragile X syndrome.
Anatomy scan of the fetal head at 20 weeks of pregnancy in a fetus affected by spina bifida. In the axial scan the characteristic lemon sign and banana sign are seen. Anatomy scan with power bi-directional colour Doppler of both fetal kidneys at 18 weeks of pregnancy to detect renal agenesis. The videoclip shows a frontal scan with normal renal ...
Infants may show facial abnormalities, micrognathia, cleft lip, spina bifida, as well as other birth defects that result from kidney, limb, and umbilical cord complications. They are also prone to being smaller than a normal sized newborn , a problem that arises while the infant is still a fetus.
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 ...
Jarcho–Levin syndrome associated with spina bifida and diastematomyelia (type I split cord malformation) 4: Duru S et al. 1999: 2: First case of 2-year-old girl, spondylocostal dysostosis with lipomyelomeningocele, and polythelia on the right side. Second case of 6-month-old girl, spondylocostal dysostosis with myelomeningocele and hydrocephalus
Spina bifida occulta means hidden split spine. [20] In this type of neural tube defect, the meninges do not herniate through the opening in the spinal canal. [19] The most frequently seen form of spina bifida occulta is when parts of the bones of the spine, called the spinous process, and the neural arch appear abnormal on a radiogram, without ...
