This is a 39-year-old woman (G4P3). The patient did not have diabetes mellitus. There was no history of prenatal teratogen exposition, nor drug ingestion or infection. During the first scan, the embryo was normal (with normal nuchal translucency). The triple test was normal too. The amniocentesis was normal (46 XY).
At 22 weeks, a sonographer diagnosed a short left femur. All the other bones were normal. The patient was referred to our unit. The same anomaly was confirmed. The profile and the head measure were normal. There were no bone fractures. All serology screening were negative. The fetal growth was normal. During the pregnancy, the femur anomaly was confirmed and the left femur seemed a little curved with no fracture.
A cesarean section was performed at 35 weeks for preeclampsia. The weight of the baby was 2460 g (45 cm). The baby was not dysmorphic. The diagnosis of the bone anomaly was confirmed with presence of left hip dysplasia. The baby is now with one year old and healthy.
