Life Spine, Inc. has announced that its ProLift® expandable interbody portfolio is now officially Magnetic Resonance Conditional in accordance with ASTM [formerly known as the American Society for Testing and Materials] standards — a designation that may not make headlines outside our world, but absolutely matters inside it.
MRI-Safe Under Conditions: ProLift Update

The status applies to ProLift, ProLift Micro and ProLift Lateral.
Designed for use across transforaminal lumbar interbody fusion, posterior lumbar interbody fusion, and lateral lumbar interbody fusion, these expandable cages now come with clearly defined MRI safety parameters.
Because We All Know the Post-Op MRI Is Coming
And it is coming for persistent radiculopathy, new contralateral symptoms, monitoring fusion progression or an unrelated neuro workup five years later.
MRI remains a cornerstone of long-term spine care.
An Magnetic Resonance Conditional designation means patients implanted with these devices may safely undergo MRI scans under specified conditions outlined in product labeling.
Engineering Beyond the OR
According to Life Spine CEO Rich Mueller, “Our team is committed to ensuring our technologies meet the evolving needs of both surgeons and patients. The confirmation of MR Conditional status reflects our continued commitment to developing carefully engineered solutions that support both procedural efficiency and long-term patient monitoring.”
The evaluation assessed magnetic field interactions, device heating, image artifact characteristics. This isn’t just a labeling tweak — it’s structured testing to define safe MRI parameters.
For orthopedic spine surgeons, this update offers clearer postoperative imaging pathways, reduced ambiguity for radiology teams, greater confidence when counseling patients and fewer “Can they get an MRI?” chart messages.
Co-Existing With MRI
Expandable interbodies have evolved significantly in recent years — better footprints, controlled expansion, lordotic options, and approach-specific designs.
Now, with Magnetic Resonance Conditional confirmation across the ProLift portfolio, Life Spine reinforces an often-overlooked truth: The surgery may last two hours. The implant stays for decades. And the MRI is never going away.
For surgeons thinking beyond the index case, that’s a practical step forward.

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.
