Ultrasound measurement of femoral anteversion.

In a recent article by Lausten, J#{248}rgensen and Boesen (1989) anteversion (AV) of the femoral neck was measured directly, by ultrasound, and by computerised tomography (CT). The authors reported poor correlation between the angles measured by ultrasound and the two other methods, and concluded that ultrasound at present seemed unsuitable for the measurement of femoral anteversion. We believe that our findings and their own results (appropriately modified) show that ultrasound is in fact a suitable method.
