Unique dans l’industrie, le système de révision acétabulaire Trabecular Metal de Zimmer définit de nouveaux standards en matière de procédures chirurgicales de révision.  Il combine la technologie Trabecular Metal avec la capacité de concevoir des solutions adaptées à chaque patient – une association qu’aucun autre système concurrent n’est en mesure d’offrir.

La conception modulaire augmente la flexibilité peropératoire.

Le système propose une approche algorithmique pour la reconstruction du cotyle.

Il fournit aux chirurgiens de nombreuses options pour répondre aux multiples insuffisances osseuses rencontrées lors de la révision acétabulaire.

Une alternative viable à l’allogreffe structurelle, sans risque de résorption ou de transmission de la maladie.

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:

• Is made entirely of Trabecular Metal Material—no substrate
• It addresses extensive superior segmental defects (Paprosky Type IIIA)
• Serves as an alternative to allograft, without potential for bone resorption or disease transmission
• Is designed to provide a technically simpler procedure, compared to using structural allograft
• Interfaces are cemented, creating a monolithic construct without concerns for micromotion
• Host bone is conserved while implant size, position, and orientation are determined by the defect
• Allows head center to be restored for optimization of patient kinetics

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:

• Cage manufactured of commercially pure titanium for optimized mechanical strength
• Left and right configurations
• Long-flange and short-flange
• Inferior flange designed to be spiked into ischium
• Shaped to fit individual patient anatomy
• Used where Trabecular Metal Revision Shell alone does not provide adequate stability
• Cage spans acetabular defects and pelvic discontinuities to provide mechanical stability of the Cup-Cage construct until biological ingrowth occurs within the Trabecular Metal Revision Shell without concerns of micromotion
• Cementing the Longevity Highly Crosslinked Polyethylene Liners, Cages, and Trabecular Metal Revision Shells together creates a single construct, without concerns of micromotion
