Bilateral Proximal Femoral Focal Deficiency in a Neonate

SUMMARY
Proximal femoral focal deficiency is a rare and complex skeletal anomaly characterized by failure of normal development of the proximal femur, shortening of the lower limb, and pelvic abnormality especially the acetabulum. It was first described by Aitken in the late 1950s. It commonly occurs as a unilateral form but the bilateral variant is rare occurring in 10-15 % of cases. To the best of our knowledge, bilateral proximal femoral focal deficiency has not been reported in Nigeria. We, therefore, present this case in a 25-day-old neonate who presented to our hospital with features consistent with this complex skeletal anomaly.
