Spina bifida (SB; / ˈ s p aɪ n ə ˈ b ɪ f ɪ d ə /; [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]
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. The foetus is facing downwards.
For example, studies show that a detailed 2nd-trimester ultrasound, also called a level 2 ultrasound, can detect about 97% of neural tube defects such as spina bifida [citation needed]. Ultrasound results may also show "soft signs," such as an Echogenic intracardiac focus or a Choroid plexus cyst, which are usually normal, but can be associated ...
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 ...

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 ...
Risks of fetal surgery, specifically prenatal spina bifida repair, include premature rupture of membranes, uterine rupture in future pregnancies, premature birth and intraspinal inclusion cysts or a tethered cord in the fetus or newborn baby. [4] Open fetal surgery has proven to be reasonably safe for the mother. [3]
