proximal focal femoral deficiency
Also written as: PFFD — proximal focal femoral deficiency
A congenital condition characterized by underdevelopment or absence of the proximal femur, resulting in significant limb length discrepancy.
Full Definition
Proximal focal femoral deficiency (PFFD) is a rare congenital limb deficiency affecting the proximal portion of the femur. The condition ranges from mild shortening with a present but abnormal femoral head to complete absence of the proximal femur and hip joint. Patients typically present with significant limb length discrepancy, hip instability, and functional limitations. The Aitken classification system is commonly used to grade the severity based on the presence of the femoral head and neck. Treatment options vary depending on severity and may include limb lengthening procedures, prosthetic fitting, or rotationplasty.
Usage
Usage note: PFFD is the preferred abbreviation over older terms like 'congenital short femur'.
