In order to address acetabular defects, porous metal revision acetabular components and augments have been developed, which require fixation to each other. The fixation technique that results in the smallest relative movement between the components, as well as its influence on the primary stability with the host bone, have not previously been determined.

多孔金属髋臼组件和增强物之间三种固定技术的稳定性比较。

为了解决髋臼缺陷，已经开发了多孔金属修复髋臼组件和增强物，它们需要彼此固定。导致组件之间相对运动最小的固定技术，以及它对与宿主骨的主要稳定性的影响，以前尚未确定。
