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 bila
teral proximal femoral focal deficiency diagnosed by ultrasound at 30
weeks' gestation. Differential diagnosis, prognosis and management are
discussed.
