Testing for Femoral Anteversion - The Hip Rotation Test
Hip Rotation Test. Patient prone, knee bent 90 degrees - rotate leg outwardly (internal leg rotation) then inwardly (external leg rotation). Note any discrepancy in the excursion of the leg.
Femoral Anteversion
Femoral anteversion is an internally rotated position of the femur. Femoral anteversion causes the knees and feet to turn inward, what is also known as a "pigeon-toed" appearance. It is twice as likely to be seen in girls and most typically is detected when the child is four to six years old.
Etiology of femoral anteversion
Femoral anteversion can be the result of:
Stiff hip muscles due to the position of the baby in the uterus
When the child is first learning how to walk, femoral anteversion can create an intoeing appearance. As the knees and feet turn in, the legs look like they are bowed.
Diagnosing Femoral Anteversion
The hip rotation test is used in the differential diagnosis. The hip joint is rotated through its internal - external range of motion (See Animation above). If the internal rotation is more than 5 degrees greater than the external rotation, femoral anteversion is diagnosed.
