The Trabecular Metal Revision Shell provides both initial and long-term stability due to its high coefficient of friction against bone with up to 80% porosity to enable ingrowth.1-4
Low modulus of elasticity of Trabecular Metal material can produce more normal physiological loading and reduce stress shielding.5
One-piece construct, created by cementing the liner, eliminates concerns about backside wear.
Elliptical geometry creates a 2-mm interference fit at the periphery of the shell, maximizing bone contact for initial stability.6
The shell is designed for use in revision and primary cases, and it is placed in best position for maximum host bone contact, while 0 degree neutral and 10 degree oblique liners allow for preferred version.
Dome screw holes allow for additional fixation into structural bone.
Longevity® Highly Crosslinked Polyethylene liners in various configurations are available to best meet patient needs.
Trabecular Metal Material has physical and mechanical properties similar to cancellous bone due to its high compressive strength and low modulus of elasticity.1,3
The Zimmer® Trabecular Metal Acetabular Revision System sets new standards in the way surgeons perform revision surgery. It combines Trabecular Metal Technology with the ability to tailor individualized solutions for each patient—a combination no other competitive system offers.
The Trabecular Metal Buttress:
No other prosthetic material simulates bone like Trabecular Metal Material. It's a 3-dimensional, porous material, not merely a coating. Additionally, it's one of the most biocompatible materials in the orthopedics industry.
The Trabecular Metal Cup Cage features include:
Trabecular Metal Material possesses a substantially higher coefficient of friction on cancellous bone than other implant materials.1 This property facilitates direct bone apposition2,3 to increase initial stability at implantation.
Bone interface shear strength (MPa) of Trabecular Metal Material is higher compared to other fixation surfaces.4,5 Trabecular Metal Material is made from Tantalum, one of the most inert elemental metal biomaterials available, Trabecular Metal Material has material properties that are remarkably similar to those of cancellous bone. Its three-dimensional architecture provides for a high-friction bone interface for a scratch fit and excellent initial implant stability. In addition, interconnecting pores enable rapid and extensive bone formation and ingrowth to achieve long-term fixation.
