Proximal Femoral Focal Deficiency

Proximal Femoral Focal Deficiency (PFFD) is a congenital disorder consisting of variable degrees of hypoplasia or absence of proximal portions of the femur. In its most devastating forms, the proximal femur as well as the femoral head and acetabulum may be absent. The patients will often present with a varus deformity in addition to the shortened limb. Associated findings in patients with PFFD include ipsilateral fibular hemimelia (absent fibula) and deformity of the foot.

 

Proximal focal femoral deficiency of the left femur. AP radiograph of an infant boy shows a markedly shortened left femur. The left femoral metaphysis and epiphysis are undergoing delayed formation when compared with the normal contralateral side. Note the absence of the fibula in the left lower extremity.
