Femoral Anteversion

Femoral anteversion is an inward twisting of the thighbone (femur). The femur is the bone that is located between the hip and the knee. This health problem causes a child’s knees and feet to turn inward. The child may have a pigeon-toed appearance.

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.

Symptoms

• Toes, knees, or both facing inward
• Bowed legs

The bowed leg stance actually helps the child balance as they stand. Balance is not as steady when the child tries to stand and walk with the feet close together or with the feet turned in. They may trip and fall.

The symptoms of femoral anteversion may seem like other health problems. Make sure your child sees their healthcare provider for a diagnosis.

Diagnosing Femoral Anteversion

Femoral anteversion is often found when a child is between ages 4 and 6. You may also first notice it when your child is learning to walk. But it may be present in children of different ages for different reasons.

Your child’s healthcare provider can diagnose femoral anteversion with a physical exam. During the exam, they will ask about your child’s birth history and if other family members are known to have the condition. Your child usually will not need X-rays.

Treatment

Treatment will depend on your child’s symptoms, age, and general health. It will also depend on how bad the condition is.

The twisting in of the thighbone usually gets better with time. Many cases correct themselves as the child grows. Your child will likely walk normally by age 8 to 10.

Most studies have found that leg braces and special shoes don't help and they are no longer used. If the femoral anteversion is bad, your child may need surgery to straighten the thighbone.

It is important to know that femoral anteversion usually does not lead to arthritis. However, it can be associated with knee pain.
