Trabecular Metal Monoblock Acetabular Cup System
Technologically advanced structure redefines performanceTrabecular Metal™ material not only looks like bone, but it also acts like bone. Its high compressive strength and low modulus of elasticity are comparable to cancellous bone. 1,2 These features are what make Trabecular Metal material — The Best Thing Next to Bone.™ |

Material The Trabecular Metal material of the Monoblock Acetabular Cup looks like natural cancellous bone. But, more importantly, it has physical and mechanical properties, including compressive strength and stiffness that are remarkably similar to cancellous bone.1 Strut Configuration The strut configuration of Trabecular Metal material has a high coefficient of friction against bone to help ensure a stable scratch fit. In addition, this 80%-porous tantalum metal material permits extensive tissue in-growth and creates a strong attachment for long-term fixation.1 Primary and Revision Solution Designed to meet the demands of both primary and revision arthroplasty, the Trabecular Metal Monoblock Acetabular Cup System combines these and other outstanding characteristics to deliver performance like nature intended. |

Initial and Long-Term Stability
Unique elliptical cup geometry creates a 2mm interference fit at the periphery of the cup, maximizing bone contact for initial and long-term stability.
Backside Wear
One piece construct eliminates concerns about backside wear.
Cup Styles
Variety of Trabecular Metal cup styles fits specific patient needs
Instrumentation
Practical instrumentation makes the Trabecular Metal Monoblock Acetabular Cup System technique simple and efficient.
