Zimmer® Trabecular Metal™ Acetabular Revision System

The Best Thing Next to Bone™

Expanding options in acetabular revision surgery

Unique in the industry, 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 individualised solutions for each patient—a combination no other competitive system offers.

 

  • Provides surgeons multiple options to address the wide range of bone deficiencies encountered in acetabular revision—without the need for custom implants
  • A viable alternative to structural allograft, without potential for resorption or disease transmission—plus, a more economical and technically easier procedure
  • Modular design increases intraoperative flexibility
  • Enables an algorithmic approach to reconstructing the acetabulu

Trabecular Metal Material: Looks like bone…acts like bone

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 orthopaedics industry, encouraging bone and soft-tissue ingrowth like no other. You can trust Trabecular Metal Implants for their:

 

  • 75–80% porosity: a permeability similar to bone (1,2,4)
  • Elasticity similar to bone, with high strength and ductility (1,2)
  • Intrinsically high friction and stability (5,6)
  • Enabling of osteoconduction and fixation (1,2,3)
  • 10 years of on going clinical success

Zimmer Total RevisionAbility is a system of comprehensive, intraoperative, solution-making capabilities that combine expert support, instrumentation, and products designed specifically to address the unpredictability of revision surgery.

The development of the Trabecular Metal Acetabular Revision System has revolutionized the way we do acetabular revision surgery. We are now able to create constructs with multiple augment options that reconstruct deficient columns and superior domes, thus providing support to the hemispherical shell and restoring the acetabulum. With Trabecular Metal Material, at five years we are seeing clinical and radiographic results for these severe defects that have been unparalleled in the past using combinations of allograft bone, cages, and plates. - Wayne Paprosky, MD
