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.
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.
What is the proximal femoral metaphysis?
The proximal physis is curved, apex proximally. As this crescent shaped physis and its trailing metaphysis grow proximally, it divides the singular cartilaginous epiphysis by forming the femoral neck as a base for the femoral head, and provides a base for the greater trochanter (Fig.
Is PFFD genetic?
Proximal femoral focal deficiency (PFFD) 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 deformed and the leg shortened.
Can you be born without femur?
Congenital femur absence is an extreme form from congenital femur deficiency. This anomaly can occur singly or in associated with another anomaly such as fibular hemimelia (most common), clubfoot, an absence of lateral foot rays, congenital cardiac defects, or spinal dysplasia.
What causes baby small femur?
In most cases, researchers suspect congenital short femur is caused by a disruption during early prenatal development, which can be caused randomly, or as a result of an outside force such as an infection or trauma.
What is congenital deficiency?
Congenital plasminogen deficiency is a disorder that results in inflamed growths on the mucous membranes, which are the moist tissues that line body openings such as the eyelids and the inside of the mouth. Development of the growths are usually triggered by infections or injury, but they may also occur spontaneously …
Where is the proximal femur?
Proximal femur includes the femoral head, neck and the region 5-cm distal to the lesser trochanter. There is a 125°–130° inclination angle between the head and neck and the femoral body. Further, there is a 15° anteversion angle between the plane passing through the condyles of the femoral head and the femur neck.
What are the major features of the proximal portion of the femur?
Answer and Explanation: Th major features of the proximal femur are the head, greater trochanter, and lesser trochanter.
How is a fracture of the proximal femur treated?
Proximal femur fractures are treated with surgery. Proximal femur fractures are treated by using IM nail or an extramedullary sliding hip screw (SHS) or hip arthroplasty methods depending on the condition of the patient or the choice of the surgeon.
What is a femur?
Your thighbone (femur) is the longest and strongest bone in your body. Because the femur is so strong, it usually takes a lot of force to break it. Motor vehicle collisions, for example, are the number one cause of femur fractures. The long, straight part of the femur is called the femoral shaft.
