Management of pregnancy in osteogenesis imperfecta: new perspectives.

Osteogenesis imperfecta during pregnancy presents increased risk to mother and fetus. In addition to the well-known skeletal changes, other recently recognized metabolic abnormalities also may lead to maternal and fetal problems during labor and delivery. A discussion of risk factors and their managment is presented. The importance of considering the possibility of fetal osteogenesis imperfecta is stressed, and cesarean section is presented as the method of choice for delivery. Important genetic factors including the lack of correlation between the severity of involvement of parent and offspring and the use of pyrophosphate analyses are discussed. An illustrative case is presented.
