[Ultrasound measurement of femur neck anteversion].

We introduce a simple method of sonographic determination of femoral neck anteversion in children with which the even difficult angels in terms of measurement, those up to 70 degrees, can be measured with sufficient reliability: The examination was done with a defined internal 40 degree rotation of the legs reached by a supporting wedge. We proved this method on 55 children's hips of which we already had an existing radiologic determination of the anteversion angle. Compared to the radiological results we found an average deviation of 3.6 degrees (standard deviation = 3.2).
