spina bifida
Pronunciation: SPIE-nah BIF-ih-dah
Congenital neural tube defect characterized by incomplete closure of the vertebral column and potential herniation of spinal cord contents.
Full Definition
Spina bifida is a congenital neural tube defect resulting from incomplete closure of the vertebral column during embryonic development. The condition ranges from spina bifida occulta (mild form with minimal symptoms) to myelomeningocele (severe form with herniation of spinal cord and meninges). In pediatric neurology documentation, spina bifida classification, level of involvement, and associated complications such as hydrocephalus, Chiari II malformation, and neurogenic bladder must be specified. The condition often requires multidisciplinary care involving neurosurgery, urology, and orthopedics.
Usage
Usage note: Specify subtype (occulta, cystica, myelomeningocele) and anatomical level when known.
