35 patients with a smooth, threaded acetabular Mecron type prosthesis were examined with the aid of a table top with wiremarkers and a fixed 30-degree wedge to allow for reproducible positioning. Under fluoroscopic control, pelvic and spot films were made. The inter- and intraobserver variability of anteversion and inclination angle measurements of the prostheses had a standard deviation of less than 1 degree. The method can be applied to other acetabular prostheses as well.
35例使用光滑螺纹型Mecron髋臼假体的患者借助带有金属丝标记的桌面和固定的30度楔形装置进行检查，以实现可重复定位。在荧光透视控制下，拍摄骨盆片和点片。假体前倾角和倾斜角测量的观察者间和观察者内变异性的标准差小于1度。该方法也可应用于其他髋臼假体。
