What is femoral Antetorsion?

What is femoral Antetorsion?

Femoral antetorsion is defined as the angle between the femoral neck and the femoral condyles (11,26). For the antetorsion measurement, the proximal reference line can be drawn on either transverse sections or oblique sections along the femoral neck axis (11,26).

What is the difference between femoral anteversion and Retroversion?

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.

How can you distinguish between tibial torsion and femoral anteversion?

Internal tibial torsion is commonly associated with sitting on the feet, while increased femoral anteversion is associated with sitting in a “W” position. Torsional deformities become more apparent with fatigue.

What is an anteversion?

Anteversion means “leaning forward.” Femoral anteversion is a condition in which the femoral neck leans forward with respect to the rest of the femur.

Is femoral anteversion a disability?

The condition is severe, with over 50 degrees of anteversion and over 80 degrees of torsion. The child has an apparent deformity more than 3 standard deviations above the mean. The child has a serious functional disability, being unable to walk and run without frequently tripping and falling.

How much femoral anteversion is normal?

Femoral anteversion averages between 30-40° at birth, and between 8-14° in adults 1, with males having a slightly less femoral anteversion than females 2.

When is Intoeing a problem?

Intoeing, commonly referred to as being pigeon toed, happens when children walk with their feet turned in. It’s a common condition that can be present at birth or develop in young children. Intoeing usually doesn’t cause pain or prevent a child from learning to walk or run and often corrects itself.

What causes anteversion?

Femoral anteversion can be the result of stiff hip muscles due to the position of the baby in the uterus. It also has a tendency to run in families. Typically, a child’s walking style looks like that of his or her parents.

Is femoral anteversion rare?

Femoral anteversion occurs in up to 10 percent of children. The condition is somewhat more common in girls than boys. It often, but not always, affects both legs. Most children don’t need treatment for femoral anteversion — the condition usually resolves on its own.

Can femoral anteversion be corrected in adults?

A closed, subtrochanteric derotation osteotomy of the femur is a safe and effective procedure to treat either femoral retroversion or excessive anteversion. Excellent or good results were obtained in 93%, despite the need for subsequent implant removal in more than two-thirds of the patients.

Can femoral anteversion be corrected?

Femoral anteversion is self-correcting in up to 99 percent of cases, and the long-term outlook is very positive for most children with the condition.

Is intoeing a disability?

Since disability from intoeing is extremely rare and most cases resolve spontaneously, observation and parental education are important from the time of diagnosis.

What does it mean to have femoral anteversion?

Hip/Femoral Anteversion. Femoral anteversion is a condition in which the femoral neck is excessively rotated forward on the femoral shaft. Excessive anteversion overloads the anterior structures of the hip joint, including the labrum and capsule, and can cause snapping.

What’s the difference between anteversion and a version?

In context|medicine|lang=en terms the difference between anteversion and version is that anteversion is (medicine) the state or condition of being anteverted while version is (medicine) a condition of the uterus in which its axis is deflected from its normal position without being bent upon itself see anteversion and retroversion.

What’s the difference between torsion neck and anteversion neck?

To differentiate these two different phenomena, the term ‘anteversion’ is used to denote the usual angel described, while ‘torsion neck’ is sued to denote the twist in the neck around its own axis measured in this work. 1,000 femora from 21 cites in different parts of the country have been measured and the average anteversion angle calculated.

Is there such a thing as femoral retroversion?

In the case of posterior orientation, the term femoral retroversion is also applied. Actually describing the intrinsic rotation of the femur over its length from the hip to the knee, femoral anteversion may also be more aptly termed femoral antetorsion.
