CHOP Hits 500 Prenatal Spina Bifida Repairs, Cementing Global Leadership — The Children's Hospital of Philadelphia

Event summary

Children's Hospital of Philadelphia (CHOP) performed its 500th prenatal repair for myelomeningocele (MMC), the most severe form of spina bifida.
The milestone follows decades of research, including the NIH-funded MOMS trial that established fetal surgery as superior to postnatal repair.
CHOP's Center for Fetal Diagnosis and Treatment has performed over 2,700 fetal surgeries since its founding in 1995.
The hospital cares for expectant parents from all 50 U.S. states and over 70 countries.

The big picture

CHOP's achievement underscores the growing shift toward prenatal intervention in congenital defects, driven by decades of clinical research. The hospital's dominance in fetal surgery reflects broader trends in pediatric care consolidation and specialization. With over 36,000 expectant parents treated since 1995, CHOP has built an unparalleled network effect in complex fetal medicine.
