Duraloc Acetabular Cup System - Design Rationale

Introduced in 1990, the Duraloc Cup has become one of the world’s most widely used cementless cup systems.
The Duraloc Cup introduced a new standard of structural integrity to help address polyethylene failure and maximize polyethylene performance. The Duraloc is a dome loaded cup, which helps ensure maximum liner/shell congruency, a minimum polyethylene thickness of 6mm and a secure locking mechanism. These features, combined with Porocoat® Porous Coating, help enhance the long-term fixation of the shell.
