NuVasive launches Modulus XLIF 3D printed titanium implants

A Modulus XLIF (eXtreme Lateral Lumbar Interbody Fusion) implant

NuVasive—a USA-based creator of minimally invasive products and procedures for spinal surgery—has announced the launch of its Modulus XLIF (eXtreme Lateral Lumbar Interbody Fusion) 3D printed, fully-porous titanium implants.

Modulus XLIF implants are described as a ‘differentiated offering’ for NuVasive’s XLIF procedure, a minimally invasive means of performing spinal fusion surgery through the side of the body. XLIF is claimed to be the only procedure of its kind, supported by 15 years’ clinical evidence and 400 peer reviews.

3D printing the implants has allowed for the realization of:

  • an organic architecture that mimics the porosity and stiffness of bone for reduced stress shielding1; and
  • a surface topography that is conducive to bone ingrowth2.

These factors, in turn, afford improved imaging characteristics over traditional titanium interbody devices.

‘We’ve seen an increase in surgeon preference to use titanium interbody options in spine surgeries, and we were confident we could develop a titanium option that delivers the porous properties surgeons need,’ said Matt Link, executive vice president (EVP) of strategy, technology and corporate development at NuVasive. ‘Modulus XLIF maximizes the potential of 3D-printed spinal implants through the application of unique and advanced software optimization processes. This product launch further represents our continued commitment to advancing surgical materials and delivering best-in-class implants that provide superior osseointegration and biomechanics.’

‘Surface architecture is an increasingly important part of the fusion process,’ said Kade Huntsman, MD, orthopedic spine surgeon at the Salt Lake Orthopaedic Clinic in Salt Lake City, Utah, USA. ‘The design of Modulus XLIF maximizes the potential of additive manufacturing through the combination of highly porous endplates with an optimized internal structure.’

NuVasive intends to showcase its Modulus XLIF implants at the North American Spine Society Annual Meeting in Orlando, Florida, USA, on October 25-28, 2017.

1 Stress shielding is the reduction in bone density (osteopenia) as a result of removal of typical stress from the bone by an implant. This occurs because bone in a healthy person or animal remodels in response to the loads it is placed under. If the loading on a bone decreases, the bone becomes less dense and weaker because there is no stimulus for the continued remodeling that is required to maintain bone mass.

2 Bone ingrowth refers to bone formation within an irregular surface (for example, beads, wire mesh, casting voids and cut groves) of an implant.
