Prenatal diagnosis of bilateral proximal femoral hypoplasia.

ABSTRACT

Proximal femoral focal deficiency is a rare skeletal disorder, with an estimated incidence of 0.11 to 0.2/10,000 births. The bilateral form is uncommon, occurring in 10 to 15% of cases. We report a case of bilateral proximal femoral focal deficiency diagnosed by ultrasound at 30 weeks' gestation. Differential diagnosis, prognosis and management are discussed.
