Modulus® Titanium Technology

Unlike any other 3D printed titanium implant on the market, Modulus is designed through a proprietary optimization algorithm that balances strength and radiolucency.


Advanced Materials Science®

Adhering to the three core principles of Advanced Materials Science—Surface, Structure, and Imaging—NuVasive has pioneered design and manufacturing methods that combine 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 surfaces2-5 on their own.

Fully porous endplate design promotes new bone on-growth and in-growth,1 demonstrating the greatest integration strength by 12 weeks compared to alternative implant materials.1

Microporous endplate architecture maximizes bone-to-implant contact, increasing expulsion resistance.6

The increased surface area and wicking capability of the porous surface improves blood to implant contact compared with traditional interbody implants.

Optimized lattice structure

Implants are designed with an optimized balance between strength and stiffness so as to minimize stress shielding7 and subsidence.8

Modulus implants implement a proprietary design optimization methodology, generating a unique internal architecture for a desired effective modulus that is similar to bone.

Capture-Modulus Imaging

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.
