Acetabular hip systems

Acetabular cup systems are built on over 25 years of market history with a focus on bone conservation and flexibility for the surgeon.

Prime acetabular system

The Prime acetabular cup system is the next step in the evolution of the successful Dynasty® acetabular cup system.

BioFoam® Cancellous Titanium

BioFoam® Cancellous Titanium represents a new generation in cementless fixation. It is a biocompatible implant that is designed to provide early fixation without compromising the long-term demands that are required in today’s increasingly young and more active patients.

A-Class® Highly Cross-Linked Polyethylene

The balanced processing of A-Class® Highly Cross-Linked Polyethylene drastically reduces wear while maintaining the material’s mechanical properties to create a superior bearing surface.

E-Class® Vitamin E Blended Highly Cross-Linked Polyethylene

Poly material selection

Specific polyethylene has been chosen to manufacture the acetabular liners with a high impact strength, tensile strength, and yield strength.¹

Cross-linking process

The selected polyethylene is subjected to a radiation cycle to facilitate cross-linking of the polymers and enhance wear resistance. The mechanical properties of the material are maintained.

Surgeon insight

“The return of range of motion is much faster, they get much better motion and they get it quicker. They're out of the hospital sooner, their pain is better and they seem to get back to the activities that they want to do at a much quicker rate.”
