    • A method for placing a prosthetic acetabular cup within an acetabulum comprises implanting an acetabular cup with an eccentric socket. The acetabular cup may be substantially hemispherical with a cup rim and a portion of the cup rim removed defining a relief. The cup may accommodate a concentric liner in an eccentric position. Screw apertures may be present on the periphery of the cup and the screw trajectories may converge toward the dome of the cup. The cup is attached to a tool which is offset relative to the cup because of the substantially eccentric socket. The relief, when the cup is secured to the acetabulum, is positioned substantially anterior and the socket is positioned more posterior to provide a more natural center of rotation of a femoral head within the socket. The first relief reduces impingement of the acetabular cup on soft tissue.
    • 用于将假体髋臼杯放置在髋臼内的方法包括:用偏心套筒植入髋臼杯。 髋臼杯可以是具有杯形边缘的大致半球形,并且杯形边缘的一部分被移除,从而限定了浮雕。 杯子可以容纳位于偏心位置的同心衬套。 螺丝孔可能存在于杯的周边上,并且螺钉的轨迹可以朝着杯的圆顶会聚。 由于基本上是偏心的插座,杯子被附接到相对于杯子偏移的工具。 当杯被固定到髋臼上时,浮雕的位置基本上位于前方,并且插座位于更靠后的位置,以在插座内提供股骨头的更自然的旋转中心。 第一个缓解减轻髋臼杯对软组织的冲击。
