[Measurement of antetorsion of the femoral neck by ultrasonics. Comparison with x-ray computed tomography].

A method of measurement of femoral anteversion using ultrasounds is presented. It is easily reproducible and non-irradiating. It was tested in 100 hips and compared with measurement by tomodensitometry. The results were similar. Both methods were tested in dry bones and the results again were comparable. It is concluded that ultrasound measurements are reliable and without danger and should be used in preference.
