Spina bifida myelomeningocele spina bifida myelomeningocele myelomeningocele is a severe type of spina bifida in which the membranes and the spinal nerves protrude at birth forming a sac on the baby s back. Because the lumbosacral spinal nerves control muscles and feelings in the lower limbs people with spina bifida have some degree of paralysis.
Spina bifida is what is known as a neural tube defect.
Sacral spina bifida. It s when the spinal cord brain or meninges their protective covering does not completely. This usually involves the lower lumbosacral spine. In spina bifida occulta the meninges and or neural tissue remain underneath skin.
The exposed nervous system may become infected so prompt surgery is needed after birth. Spina bifida is commonly found in the lumbar and sacral spine. Spina bifida progresses from a cleft or splitlike opening in the back part of the backbones the spinal vertebrae.
Spina bifida occulta is a congenital defect which occurs in the neural tube when the bony plates that form the bony spine covering the spinal cord do not form completely resulting in a defect of the spinous process spinous cleft or laminae paraspinal cleft 3 4. This defect is indicated more often by a skin lesion such as a hairy patch dermal sinus tract dimple hemangioma or lipoma the occurrence of spina bifida occulta in sacral region spreading from s1 to s5 has been termed as sacral spina bifida occulta ssbo. The most common location is the lower back but in rare cases it may be in the middle back or neck.
There are three main types. It occurs during development prior to birth. Spina bifida 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.
Spina bifida cleft spine is a birth defect affecting the spinal column. Spina bifida occulta meningocele and myelomeningocele. In more severe cases it involves the spinal cord.
