Plain films were taken from 5 adults femura (with different angles of antetorsion) varying the rotation between +70 degrees to -50 degrees. An astonishingly constant relations between the structures of proximal femur and the axis of the femural condyle has been found, independent from the angle of antetorsion. According to our opinion the rotation in an adult hip joint can be estimated with an accuracy of +/- 10% from a.-p. film alone. A simple method for determining the rotation has been suggested and may be put to further discussion.
对5具不同前倾角度（旋转角度在+70度至-50度之间变化）的成人股骨拍摄X线平片。结果发现，股骨近端结构与股骨髁轴线之间存在惊人的恒定关系，且与前倾角度无关。我们认为，仅通过前后位X线片就能以±10%的精度估计成人髋关节的旋转情况。本文提出了一种简单的旋转测定方法，可供进一步探讨。
