Myelomeningocele (MMC), also known as open spina bifida, is a serious congenital condition in which the cord and meninges protrude through the spinal column's defective bony encasement due to a defective closure of the posterior portion of the neural tube between the fourth week of pregnancy.

The formation of the defect is influenced by both genetic and environmental factors, while the exact cause is yet unknown. There is currently no effective treatment for this common and debilitating central nervous system (CNS) dysfunction.
