spina bifida
Pronunciation: SPY-nah BIF-ih-dah
Congenital neural tube defect resulting in incomplete closure of the vertebral column, often requiring orthopedic management.
Full Definition
Spina bifida is a congenital neural tube defect characterized by incomplete closure of the vertebral column during embryonic development. The condition exists in several forms: spina bifida occulta (mildest form with minimal clinical significance), meningocele (protrusion of meninges through the defect), and myelomeningocele (most severe form involving herniation of neural tissue and meninges). Children with spina bifida, particularly myelomeningocele, often require extensive orthopedic management including treatment of paralytic deformities, scoliosis, hip dislocations, and foot deformities. Management requires a multidisciplinary approach involving neurosurgery, orthopedics, urology, and rehabilitation services.
Usage
Usage note: Specify the type and neurological level when documenting. Often abbreviated as SB in clinical notes.
