This cervical fusion device provides an excellent balance between porosity and strength. TM-S is the only cervical spinal implant made with Trabecular Metal Material. It offers a high coefficient of friction to help prevent device migration and expulsion, as well as a low modulus of elasticity that may improve load-sharing, which potentially minimizes stress-shielding. With its average porosity of up to 80% and a consistent open pore structure, the material is also designed to resemble the structure and mechanical properties of cancellous bone, which provides an excellent environment for boney in-growth and vascularization.
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 the potential for 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 the potential for 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 bone ingrowth.
Trabecular Metal Material had more than 10 years of clinical results and has been used in over 200,000 orthopedic cases worldwide.
The Trabecular Metal Cervical Fusion Device is intended for use in anterior cervical discectomy and fusion (ACDF) procedures in patients with symptomatic cervical disc disease from the C3- C4 disc to the C7-T1 disc.
