Modulus™
Porous Titanium
Modulus™ is designed through a proprietary optimization algorithm that balances strength and radiolucency. Adhering to the three core principles of Advanced Materials Science™—surface, structure, and imaging—Modulus™ combines the inherent benefits of porosity with the advantageous material properties of titanium to create implants intelligently designed for fusion.
Porous Surface Designed to Participate in Fusion
Porosity elicits a significantly stronger osteogenic response at the cellular level compared to roughened or nano-roughened surfaces1-5 on their own.
A fully porous endplate design promotes new bone ongrowth and ingrowth,1 demonstrating the greatest integration strength by 12 weeks compared to alternative implant materials in an ovine model.1 Microporous endplate architecture maximizes bone-to-implant contact, increasing expulsion resistance.6
The increased surface area and wicking capability of the porous surface is designed to improve blood-to-implant contact compared with traditional interbody implants.
Optimized Lattice Structure
Modulus™ implants are designed with an optimized balance between strength and stiffness to minimize stress shielding7 and subsidence.8 The implants implement a proprietary design optimization methodology, generating a unique internal architecture for a desired effective modulus that is similar to bone.
Enhanced Imaging Characteristics for Visualization of Fusion
Created with imaging clarity in mind, the proprietary implant design and manufacturing process allow enhanced visualization on a variety of imaging modalities.
