Fetal Surgery for Spina Bifida (Myelomeningocele, MMC)

Fetal surgery for myelomeningocele (MMC), the most severe form of spina bifida, is a delicate surgical procedure where fetal surgeons open the uterus and close the opening in the baby's back while they are still in the womb. Fetal spina bifida surgery is shown to offer significantly better results than traditional repair after birth. Because spinal cord damage is progressive during gestation, prenatal repair of myelomeningocele may prevent further damage. (Watch a video to learn more about fetal repair of spina bifida.)
