Microport - Model Prime - Orthopedics Acetabular Cup Systems
From Hips - Primary Acetabular Hip System
The Prime acetabular cup system is the next step in the evolution of the successful Dynasty® acetabular cup system. The system is optimized for a highly cross-linked ultra-high molecular weight polyethylene bearing surface, eliminating the compromises associated with modularity to accommodate alternative bearing surfaces. By focusing on a singular bearing surface, the shell has also been optimized for modern fixation surfaces. Designed with simple, versatile instrumentation, the system can be used with a variety of surgical approaches.

Design Features
- BioFoam® cancellous titanium
- Provides immediate initial fixation and acts as an osteoconductive matrix to promote biological fixation
- Optimized Screw hole design
- Position of the screw holes creates divergent fixation, while the geometry of the hole allows for 18° of screw angulation (9° off axis) without interference with liner insertion
- Robust locking mechanism
- Working in conjunction with low-profile, self positioning anti-rotation tabs, this feature maximizes push-out strength while allowing for easy liner insertion and multiple liner configuration options
- Optimized head to shell ratio
- Offers increased jump distance for dislocation without any compromise to liner thickness, which promotes joint stability
- Minimized shell thickness
- Decreases stiffness of the implant, discourages stress-shielding, and allows for optimized liner thickness
- Square impaction dimple
- Provides rotational stability and control to simplify implantation
