Proximal femoral focal deficiency

Proximal femoral focal deficiency (PFFD), also known as Congenital Femoral Deficiency (CFD), is a rare, non-hereditary birth defect that affects the pelvis, particularly the hip bone, and the proximal femur. The disorder may affect one side or both, with the hip being either mobile and stable, or immobile and unstable. The affected leg is noticeably shorter than the other, with the degree of discrepancy varying.

Etiology

The exact cause of PFFD is unknown. It is not believed to be genetic, as it does not typically run in families. Some researchers suggest that it may be the result of a disruption in blood supply to the fetal hip during early development.

Classification

PFFD is classified into four types, according to the Aitken classification system. Type A is the least severe, with the femoral head present and the acetabulum well-formed. Type D is the most severe, with a complete absence of the femoral head and acetabulum.

Treatment

Treatment options for PFFD vary depending on the severity of the condition. Non-surgical treatments include the use of prosthetics and orthotics. Surgical options include limb lengthening procedures, rotationplasty, and hip and knee reconstruction surgeries.

Prognosis

The prognosis for individuals with PFFD varies. With appropriate treatment, most individuals are able to lead active lives. However, they may face challenges related to mobility and may require adaptations to perform certain tasks.
