According to NuVasive’s press announcement, “Modulus TLIF-O features porous surface technology that, based on pre-clinical data, provides a favorable environment for bone in-growth and bone on-growth, and consistently achieves stronger osseointegration than solid implants with smooth or rough surfaces.”
“The porous and roughened endplate design promotes new bone on-growth at four weeks and demonstrates the greatest integration strength by 12 weeks compared to alternative implant materials. Modulus TLIF-O’s lattice structure is optimized for each implant size through NuVasive’s proprietary algorithm that balances strength and radiolucency, while also mimicking the stiffness of bone.”
“This optimized lattice structure enables enhanced imaging for visualization of spinal fusion compared to solid titanium interbody implants. Modulus TLIF-O’s lordosis cut in the oblique plane, along with the ability to insert and rotate or impact the implant using the same instrumentation, enables surgeons to restore sagittal alignment of the spine while avoiding introduction of an undesired coronal misalignment.”
NuVasive President Matt Link told OTW, “The most exciting aspect of the Modulus TLIF-O implant, beyond its porous surface technology, is the lattice structure is optimized for each implant size through NuVasive’s proprietary algorithm that balances strength and radiolucency.”
“The implant’s unique geometry facilitates the ease of impaction into the disc space either through straight impaction or an insert and rotate technique using the same instrumentation. This enables surgeons to restore proper disc height while providing maximum sagittal correction.”
“Modulus TLIF-O’s porous titanium technology and optimized lattice structure truly differentiates this implant from what is currently on the market. I am proud of the work our teams have done to further the application of this technology and expand NuVasive’s Advanced Materials Science portfolio to the most common procedure in spine,” he added.

This is a fascinating development. In my practice we've seen similar outcomes with the revised protocol. The key differentiator seems to be patient selection criteria. Has anyone else noticed the correlation with BMI thresholds?
Great point. I'd push back slightly on the conclusion, the sample size in the cited study is too small to draw population-level inferences. That said, the directional signal is compelling and worth a larger RCT.
We implemented a similar approach last year. Early results are promising but we're still gathering 12-month follow-up data. Happy to share our protocol if anyone is interested.
