Thirty-two macerated femora were examined by CT in order to determine the degree of anteversion and to relate this to the position of the femur and to the various reference lines quoted in the literature. The accuracy of CT is the same as that of the Rippstein method, provided the following conditions are met: 1. Position of the femur with its long axis perpendicular to the image plane. 2. Demonstration of the maximal configuration of the femoral condyles to enable one to construct a tangent to the dorsal aspect of the condyle. 3. Demonstration of the head and neck by a plane which divides the neck into approximately equal portions and sections the femoral head. These conditions are more easily met, even in immobile patients, than the requirements for the Rippstein method.
对32具浸软的股骨进行CT检查，以确定前倾角，并将其与股骨位置以及文献中引用的各种参考线相关联。如果满足以下条件，CT的准确性与里普斯坦方法相同：1. 股骨长轴垂直于图像平面。2. 显示股骨髁的最大形态，以便能够构建髁背侧的切线。3. 通过将股骨颈大致分成相等部分并剖切股骨头的平面显示股骨头和颈。即使在不能活动的患者中，这些条件也比里普斯坦方法的要求更容易满足。
