PFFD
Pronunciation: P-F-F-D
Also written as: PFFD — Proximal Focal Femoral Deficiency
Proximal focal femoral deficiency, a rare congenital anomaly involving underdevelopment of the upper portion of the femur.
Full Definition
Proximal focal femoral deficiency (PFFD) is a rare congenital malformation characterized by deficiency of the proximal femur, ranging from mild shortening to complete absence of the femoral head and neck. The condition results in significant limb length discrepancy and hip instability. Classification systems (Aitken, Paley) help guide treatment planning. Radiographic assessment includes evaluation of the femoral head, acetabulum, and subtrochanteric region. Associated anomalies may include fibular deficiency and spinal abnormalities. Treatment options range from limb lengthening procedures to amputation and prosthetic fitting, depending on the severity and functional potential.
Usage
Usage note: Always written in capital letters. Specify Aitken classification when applicable.
