Most patients with mild to moderate congenital femoral deficiency/proximal femoral focal deficiency can be successfully treated with limb reconstruction and sequential limb lengthening. Initial treatment begins around the age of 18-24 months. This initial treatment consists of joint reconstruction for the hip and knee.
How common is congenital femoral deficiency?
CFD is a rare condition; one or two out of every 100,000 children are affected. Congenital femoral deficiency can affect one side of the body, or both.
What causes congenital femoral deficiency?
Researchers suspect it is caused by a disruption during early prenatal development, which may occur randomly or as a result of an environmental factor such as infection or trauma. Taking the drug thalidomide during pregnancy can cause CFD and other limb deficiencies in an unborn child.
How common is proximal femoral focal deficiency?
Proximal femoral focal deficiency (PFFD) is an uncommon condition that affects about 1 in every 200,000 children, and can vary in severity from child to child.
Is proximal focal femoral deficiency genetic?
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.
Can you be born without femur?
In some children, a birth defect causes the femur to be shorter than it should be. This lead to other developmental issues, such as deformity and instability of the hip and knee. Congenital femoral deficiency typically impacts just one femur, though it can affect both.
What is congenital short femur?
Congenital short femur is a rare type of congenital malformation that occurs during prenatal development and affects the growth of the femur bone in the upper leg.
What are femoral defects?
The Paprosky classification of proximal femoral defects is used to assess the amount of bone loss and define the morphology of remaining proximal femoral bone stock; it also provides guidelines for treatment. Paprosky type I defects are characterized by minimal metaphyseal cancellous bone loss with intact diaphysis.
What causes COXA Vara?
The most common cause of coxa vara is either congenital or developmental. Other common causes include metabolic bone diseases (e.g. Paget’s disease of bone), post-Perthes deformity, osteomyelitis, and post traumatic (due to improper healing of a fracture between the greater and lesser trochanter).
