Nexxt Spine, LLC has begun a full market launch of a truly novel corpectomy system for the stabilization of the spine. This system, according to Nexxt Spine, will make it easier to adapt to a patient’s anatomy and the surgeon’s requirements.
Nexxt Spine Launches Novel Spine Corpectomy System

To begin with, explains Nexxt Spine president Andy Elsbury, “NEXXT MATRIXX® Corpectomy has the ability to fuse, as opposed to just being a support structure, and NEXXT MATRIXX is available in 1mm increments from 11mm to 71mm to precisely fit each patient, which has surgeons excited.”
“We designed the NEXXT MATRIXX Corpectomy System to give surgeon users several distinct benefits for the unique challenges associated with the corpectomy procedures, which sets this system apart from traditional static, corpectomy devices.”
According to the company, NEXXT MATRIXX Corpectomy System features include:
- Porous lattice landscapes on the superior/inferior endplates, anterior/posterior sides, and lateral sides of the devices to encourage the potential for fusion from end plate to end plate.
- Aggressive inferior/superior teeth on the endplate and device heights in 1 mm increments provide simple and secure placement.
- Multiple footprints (12mmx14mm, 14mmx16mm), heights (11-50mm) and lordotic options (0°, 6°), designed to meet the needs of the patient’s anatomy
NEXXT MATRIXX, of course, is manufactured using NEXXT Spine’s proprietary technology of intentionally engineered 3D laser printed titanium devices. It also includes the 5 Core Pillars for a successful fusion. But wait, there’s more:
- Varying pore sizes of 300µm, 500µm, and 700µm pores to support vascularization and osteogenesis
- A 75% open porous structure to increase surface area for nutrient exchange and potential volume for boney in-growth
- A 7µm micro-roughened surface to increase osteoblast differentiation, production of angiogenic factors, and surface osteointegration
- An integral modulus of elasticity engineered to be comparable to PEEK devices leading to a more physiological product
- 700µm A/P and lateral lattice geometry to provide robust, unimpeded radiographic imaging by reducing overall titanium material and device density.

Discussion
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.
