fetal skeletal dysplasia

Skeletal dysplasia diagnosis. Skeletal dysplasia can cause abnormalities of the bones in the body, such as the size and shape of the skull, legs, arms and trunk. Although more than 450 skeletal dysplasias have been identified, only a few are lethal in the prenatal/postnatal period. They have an incidence of 2/10,000 live births and a lethality of approximately 50%, which makes their prenatal diagnosis of particular importance in determining fetal outcomes as well as in genetic counseling for future pregnancies ( 1 ).
