What is the angle of anteversion?
Femoral neck anteversion (FNA) is the angle between the femoral neck and femoral shaft, indicating the degree of torsion of the femur. Differences in FNA affect the biomechanics of the hip, through alterations in factors such as moment arm lengths and joint loading.
What causes anteversion?
What causes femoral anteversion in a child? Femoral anteversion can be the result of stiff hip muscles because of the position of the baby in the uterus. It also tends to run in families. Typically, a child’s walking style looks like that of their parents.
What is the difference between retroversion and anteversion?
Femoral retroversion is a rotational or torsional deformity in which the femur twists backward (outward) relative to the knee. The opposite condition, in which the femur has an abnormal forward (inward) rotation, is called femoral anteversion. The condition is usually congenital, meaning children are born with it.

What causes hip anteversion?
Causes of femoral anteversion The exact cause is unknown, however, femoral anteversion is congenital (present since birth) and develops while a child is in the womb. It appears to be related to the position of the baby while growing in the uterus.
How is femoral anteversion treated?
A surgery called a femoral derotational osteotomy may be done to correct femoral anteversion. The surgery involves separating the femur bone and rotating it to the correct position. The pieces are then held in place by a rod that is inserted inside the bone.
When is femoral anteversion?
This condition will usually correct on its own over time, as the child grows. Often by the age of 8 to 10 years of age, it has resolved by itself. However, in some children, the rotation remains.
How is femoral anteversion diagnosed?
The diagnosis of femoral anteversion is made by a history and physical examination by your child’s doctor. During the examination, the doctor obtains a complete prenatal and birth history of the child and asks if other family members are known to have femoral anteversion. Generally, no X-rays are necessary.
Why does femoral anteversion occur?
Femoral anteversion forms during development of the fetus in the womb. It typically affects both legs and is more common in girls. The exact mechanism behind femoral anteversion is unknown. It is thought to be related to genetic factors and the position of the fetus in the uterus.
What does Anteflexion mean?
