- Discussion:
-
Spina Bifida refers to a local failure of primordia of the two laminae to unite leaves vertebral canal open
dorsally (spinal rachischisis, or spina bifida);
- dorsal body wall may or may not be intact over open vertebral canal;
-
sub-types:
-
spina bifida occulta:
- defect involves primarily bone, but skin may be attached to
Dura, spinal cord, or nerve roots by fibrous bands;
-
spina bifida cystica:
- neural tissue may be exposed (myeloschisis)
- meninges may protrude (meningocele)
- spinal cord may protrude (myelomeningocele);
-
diastematomyelia:
- related to spina bifida is condition known as diastematomyelia, in which the
spinal cord is split by bony spicule or a fibrous band,
w/ each portion surrounded by a dural sac;
- as child grows, a long spicule of bone or a fibrous band may tether
spinal cord and produce neurologic deficits;
