ABSTRACT

Congenital femoral deficiency (CFD) is a spectrum of severity of femoral deficiency and deformity. Deficiency implies a lack of integrity, stability, and mobility of the hip and knee joints. Deformity refers to bone malorientation, bone malrotation, and soft tissue contractures of the hip and knee. Both deficiencies and deformities are present at birth, nonprogressive, and of variable degree.
