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]
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 involvement of the spinal cord and spinal nerves. [21] The risk of recurrence in those who have a first degree relative (a parent or sibling) is 5–10 times ...
Spina bifida is characterized by a midline cleft in the vertebral arch. It usually causes no symptoms in dogs. It usually causes no symptoms in dogs. It is seen most commonly in Bulldogs and Manx cats. [ 5 ]
Diastematomyelia is a "dysraphic state" of unknown embryonic origin, but is probably initiated by an accessory neurenteric canal (an additional embryonic spinal canal.).) This condition may be an isolated phenomenon or may be associated with other segmental anomalies of the vertebral bodies such as spina bifida, kyphoscoliosis, butterfly vertebra, hemivertebra and block vertebrae which are ...
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 ...
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.
It is a multifactorial aetiology and is most typically accompanied by other defects. Rachischisis is often described as a severe form of spina bifida, with the spine not only being exposed to the exterior environment, but with the opening being large enough to allow the neural plate to spread out of the opening and to the surface.
