An acetabular cup with a 270 degree rim wire has been designed to assist in the radiographic assessment of acetabular cup orientation in total hip arthroplasty. A study was conducted analyzing the component in various positions of lateral opening and version with three different X-ray-beam centering positions. The 270 degree acetabular rim wire allowed for easy and accurate assessment of component orientation when the pelvis was level and the central ray of the X-ray beam was centered over the hip.
一种带有270度边缘金属丝的髋臼杯被设计用于辅助全髋关节置换术中髋臼杯方向的影像学评估。进行了一项研究，分析该部件在不同外展和前倾位置以及三种不同X射线束中心位置时的情况。当骨盆处于水平位且X射线束的中心线对准髋关节时，270度髋臼边缘金属丝便于对部件方向进行轻松且准确的评估。
