Femoral Anteversion

Most children don't need treatment for femoral anteversion, since the condition usually resolves on it own. For kids who need surgery for severe forms of the condition, the outlook is excellent. The surgeries are quite safe. And in kids, the bones heal quite reliably, so they should do very well.

If your child has been diagnosed with femoral anteversion, you’ll have concerns and questions about her health, treatment, recovery and other issues. It may comfort you to know that Boston Children's Hospital is a world leader in pediatric orthopedics, and we have a wealth of experience helping children with this fairly common and treatable hip condition. We specialize in innovative, family-centered care that supports your child and family every step of the way.

What is femoral anteversion?

Femoral anteversion is an inward twisting of the thigh bone (called the femur — the bone located between the hip and knee). Femoral anteversion causes a child's knees and feet to turn inward and have a "pigeon-toed" appearance.

It usually shows up when a child is between 2 and 4 years old (the time period when inward rotation from the hip tends to increase), and is most obvious at age 5 to 6. The condition is somewhat more common in girls than boys. It often, but not always, occurs symmetrically in both thigh bones.
