NASS Sees Launch of First New MIS Fully Articulating Expandable Spacer for Spinal Fusion

It’s all spine news this week as NASS is taking place. At the event expandable interbody technology specialist Globus Medical, Inc., has launched ALTERA™, which it says is the first new minimally invasive fully articulating expandable spacer for spinal fusion.


The ALTERA™ Spacer is an interbody fusion device intended for use in patients with degenerative disc disease (DDD) at one or two contiguous levels of the lumbosacral spine (L2-S1).

Its use is indicated in skeletally mature patients who have had at least six months of non-operative treatment. In addition, these patients may have up to Grade 1 spondylolisthesis or retrolisthesis at the involved level(s). The ALTERA™ Spacer is to be filled with autogenous bone graft material and ALTERA™ allows for in-situ delivery of autogenous bone graft into, as well as around, the implant after it has been expanded.

Globus claims its Altera delivers the benefits of minimized insertion height, continuous expansion and optimized fit. Because of the articulation into anterior placement and the option for 8° or 15° profile angles, Altera optimizes lordosis compared to standard static transforaminal lumbar interbody fusion (TLIF) crescent-shaped spacers. It is also designed to maintain sagittal balance while reducing the challenges of insertion: the spacer is inserted at a minimized height, articulated into an anterior position, and then expanded vertically to optimize fit.

Altera devices are intended to be used with supplemental fixation.

Physician comments

“This is a big improvement over other TLIF cages available today. The steerable articulaton and vertical expansion of ALTERA™, tailoring lumbar balance and proper posture without the need for successive trialing, is a game-changer. The ability to completely pack the expanded graft window through a separate port creates optimal fusion conditions,” commented Dr. Paul K. Kim, Neurosurgeon at Carolina Neurosurgery and Spine Associates.

Company comments

“Globus has led the way with our growing portfolio of transformative, disruptive technologies; we have had great reception and ongoing success with our CALIBER®, RISE®, CALIBER®-L, LATIS™, and MONUMENT™ interbody cages. Each of these implants along with ALTERA™ offers a better solution over traditional cages, be it a simplified procedure, tailored and optimized fit, or ease of insertion with minimal impaction. We are excited about the prospects for ALTERA™, which is the fourth new disruptive TLIF expandable technology we’ve launched in as many years for Globus,” commented Andrew Iott, Senior Vice President of Product Development.
