Rariographic estimation of the angles between femoral neck and shaft and of antetorsion is a standard examination, particularly in infantile dysplasia. In the radiographs taken, mistakes are made owing to incorrect positioning of the patient. Recognition and prevention of incorrect positioning are discussed using Rippstein's radiographic technique for measuring the neck-shaft angle. Typical mistakes are shown and guidelines for correct positioning given. Since positioning with the legs abducted is technically limited, and alternative, different technique of positioning is described which appears to be less demanding.
通过X线片估计股骨颈与股骨干之间的角度以及前倾角是一项标准检查，尤其是在婴儿发育异常的情况下。在拍摄的X线片中，由于患者体位摆放不正确会出现错误。使用里普斯坦测量颈干角的X线片技术讨论了对不正确体位的识别和预防。展示了典型错误并给出了正确体位的指导原则。由于双腿外展时的体位摆放技术上有限，因此描述了一种替代性的、不同的体位摆放技术，该技术要求似乎较低。
