Congenital Spinal Cord Injury Flashcards
Spina Bifida Chiari II Malformation
2 main categories of spinal cord injury:
- Congenital SCI
- Traumatic SCI
Where does congenital SCI occurs?
in utero
Defect in neural tube closure & overlying posterior vertebral arches
Spina Bifida
Two types of spina bifida:
- Spina bifida occulta
- Spina bifida cystica
In what type of congenital SCI there is a failure of one or more of the vertebral arches to fuse in the 3rd month of gestation, there no SC and meninges involved, and is covered by skin with a patch of hair or dimple ?
Spina Bifida Oculta
Are there usually any resultant neurological or musculoskeletal impairments seen in pt with spina bifida oculta?
no
Cystic protrusions of meninges alone or both meninges & spinal cord through defective vertebral arches
Spina Bifida Cystica
What are the types of spina bifida cystica?
Which is the most common type?
- Meningocele
- Myelocele (myelocystocele)
- Lipomeningocele
- Myelomeningocele (most common)
Meningocele
myelomeningocele
spina bifida oculta
Which is the milder form of spina bifida?
meningocele
Neural tube closes normally, but central canal of spinal cord distends & produces large, skin covered cyst:
myelocele (myelocystocele)
Protrusion of meninges & CSF into cystic sac, SC remains within vertebral canal, and is relatively uncommon form of spina bifida
meningocele
- Rare form of spina bifida
- Prompt medical intervention is required
- Neural tube closes normally, but is distended due to cystic swelling
Myelocele (myelocystocele)
Due to vertebral defect associated with superficial fatty mass (lipoma) that merges with lower level of spinal cord
lipomeningocele
Most common & severe form of spina bifida cystica where both spinal cord & meninges protrude into cystic sac, and results in abnormal transmission of neural impulses
myelomeningocele (spina bifida)
