What is increased femoral anteversion?
Femoral anteversion is an inward twisting of the thigh bone (femur). Femoral anteversion causes a child’s knees and feet to turn inward and have a “pigeon-toed” appearance. This is also called in-toeing.
What age is femoral anteversion more common?
Femoral anteversion is usually most noticeable in children between the ages of 4 and 6.
What is femoral anteversion angle?
Femoral anteversion angle (FAVA) is the angle formed by a line anteriorly projecting from the femoral neck compared to the femoral shaft when the femur is examined along its long axis from top. Assessment entails measurement of the femoral neck angle with modifications made for rotation of the femoral condyles.
Does femoral anteversion cause knee pain?
Background: Excessive femoral anteversion is a developmental condition that can become symptomatic into adolescence and manifest as anterior knee pain, tripping, and or problems with sports. Femoral derotational osteotomy about an antegrade intramedullary nail (IMN) is an accepted option to treat this condition.
What is a normal femoral anteversion angle?
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.
How do you know if you have femoral anteversion?
Symptoms of femoral anteversion
- Signs and symptoms of femoral anteversion include:
- In-toeing, in which a person walks “pigeon-toed,” with each foot pointed slightly toward the other.
- Bowlegs (also called bowed legs).
- Pain in the hips, knees and/or ankles.
- Snapping sound in the hip while walking.
What does it mean to have femoral anteversion?
Anteversion refers to an abnormal forward rotation. What is femoral anteversion? What is femoral anteversion? Also called hip anteversion, femoral anteversion is a forward (inward) rotation in the femur (thighbone), which connects to the pelvis to form the hip joint. In other words the knee is excessively twisted inward relative to the hip.
When to see a specialist for femoral anteversion?
A specialist will observe your child to see if the toes and/or kneecaps turn inward as he or she walks. The physical exam is typically conducted with the child laying down. This position helps determine the degree of the femur’s internal rotation. Femoral anteversion usually improves as a child grows.
What causes the femoral neck to rotate forward?
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. Excessive femoral anteversion;
Which is the anterior orientation of the femur?
In most cases, the femoral neck is oriented anteriorly as compared to the femoral condyles. 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.
