EOS imaging will be working with Montreal-based Spinologics Inc. to develop a biomechanical simulation software dedicated to spine surgery planning. The new software will be integrated into EOS imaging’s cloud-based, 3D planning software.
EOS imaging Partnering With Spinologics for Simulation Software

According to the January 19, 2016 news release, “The biomechanical model of the spine and the pelvis provides input to define a planned correction taking into account the spine stiffness, while predicting if there could be a risk of failure along the course of treatment. It will bring particular value to the correction of elderly patient deformity and degenerative spine conditions for which spine flexibility is diminished. The approach also applies to paediatric surgery.”
Marie Meynadier, Ph.D., CEO of EOS imaging said, “We have a lot of respect for the novel solutions that Spinologics has brought to the market to advance clinical outcomes for patients. Our co-development will be integrated in the next generation of our soon to be released 3D spinal surgical planning. It is a strong added value to our web based surgical planning applications, in line with our strategy of proposing to surgeons “virtual patients”, 3D patient specific models on which planning and simulation of surgeries can be performed. The better surgeries are planned and simulated, the least patients will undergo costly and painful revision surgeries.”
As indicated in the news release, “The joint development effort will utilize patient-specific 3D datasets from EOS exams to simulate in-situ bending, vertebral de-rotation, contraction-distraction as well as gravitational effects. The new capability should allow surgeons to better understand and anticipate the effects of forces on the spine while planning initial and revision surgeries. EOS imaging will have the exclusive rights to sell the new software worldwide with an anticipated release date of the first product by mid-2017.”
Stefan Parent, CEO of Spinologics said: “We are proud to team up with EOS imaging and to bring our technology to what we estimate being today the standard of care in spine imaging. As surgeons, we are convinced that spine surgery deserves adequate planning and simulation and that our technology and co-development will be of high value for a better and safer treatment of spine pathologies”.
Asked how this will affect pre-op planning, Meynadier told OTW, “Our goal is to help surgeons be as prepared as possible to what will happen in the OR, and to allow them to share with their patient a personalized and realistic correction target.”
“We hope to make a significant first step in spine correction planning with spineEOS, which will be launched in 2016, a unique tool that uses weight-bearing 3D patient data to plan spine surgery.”

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.
