No other porous material so closely resembles the structure, function and physiology of trabecular bone.
Trabecular Metal Material is a highly porous structure with a nano-textured strut architecture that creates an initial scratch fit and facilitates the long-term biologic attachment of orthopaedic implants via bone ingrowth. Trabecular Metal Material is the most advanced fixation surface available for orthopaedic implants. Clinical use since 1997 demonstrates that this innovative technology provides excellent initial scratch fit and stable, long-term fixation. No other porous metal material so closely resembles the structure, function and physiology of cancellous bone.

Trabecular Metal has a coefficient of friction of .98 against cancellous bone. This produces a good "scratch fit" and increases the material's initial fixation and stability to bone. Good initial fixation secures the implant in place, allowing time for bony ingrowth and ongrowth.
Trabecular Metal Material is ductile, which means it has a "bend before break" quality. The structure of Trabecular Metal allows it to withstand physiological loading. Its flexibility is similar to bone and in turn reduces the potential for stress shielding. The implant moves with the bone, allowing the underlying bone to become stronger and denser.
Trabecular Metal Material has more than 10 years of clinical results and has been used in over 200,000 joint replacement cases worldwide.
