The Proven Advantages of Zimmer® Trabecular Metal Material
|
Simply put, it simulates bone like no other prosthetic material. That’s because Trabecular Metal Material is designed to replicate the shape, the cellular structure, the elasticity, and the weight-bearing characteristics of bone. It’s a unique, highly porous, three-dimensional biomaterial, not a coating. Thus, it allows significant bone and soft-tissue ingrowth. With over 200,000 worldwide surgeries performed since 1997 using Trabecular Metal Implants, the results are in: Trabecular Metal Material is indeed The Best Thing Next to Bone.™ |
