Maternal-Fetal Skeletal Disorders Program

Baby spine ultrasound

The Maternal-Fetal Skeletal Disorders Center at Johns Hopkins combines the specific expertise of prenatal specialists in Maternal-Fetal Medicine with pediatric and adult specialists in the Greenberg Center for Skeletal Dysplasias. We provide prenatal ultrasound and other imaging, genetic counseling, diagnostic testing and high risk obstetrical consultation for a variety of bone conditions that present in the mother or fetus. We also provide fetal echocardiography to specifically evaluate for a cardiac anomaly as well as 3D/4D ultrasound to assist with diagnosis. Multidisciplinary care during pregnancy can be coordinated with your provider and our care team, tailored to each couple's unique needs including the transition through the birth process and neonatal care.
