A pregnant woman was referred to the obstetrics department at a hospital because her doctor considered that her baby might have some congenital skeletal disorder. Echography of the fetus revealed that the fetal femur growth stopped at 27 weeks of gestational age and that the femur length was very short at 33 weeks (−6.7 SD). The chest of the fetus was hypoplastic. In contrast to her baby’s short limbs and narrow chest, its head was large (+1.9 SD). Cephalopelvic disproportion was suspected. Therefore, her doctor chose to conduct a cesarean section.
