Grenoble, France-based eCential Robotics, a company specializing in surgical robotics, and Knoxville, Tennessee-based ChoiceSpine LLC, a spinal device company, have announced a partnership to offer, according to the companies, “common optimized solutions.”
eCential Robotics and ChoiceSpine Announce Partnership
Discussions regarding a partnership began in 2021. The companies plan to combine the benefits of the eCential Robotics platform with the unique features of the ChoiceSpine product portfolio, telling OTW, the new system “combines navigation, robotics, and implant systems that are easy to use, accurate for spine surgeons, and benefits the patient.”
OTW spoke with eCential Robotics Chief Strategy Officer Laurence Chabanas about the partnership. Chabanas told OTW, “The partnership was initiated by surgeons who knew both companies and had seen an interest in having us meet.”
Chabanas continued, “We saw a benefit on both sides: for ChoiceSpine, getting on board the robotics train, and for eCential Robotics, an optimization of our solution in the framework of our ‘open’ model and an additional opportunity to structure our presence on the U.S. market.”
The eCential Robotics platform joins together intraoperative robotics, 2D/3D imaging, and navigation. It offers a single-user interface that incorporates a range of spine surgery applications. In the future, these applications will expand to include, per the press release, “multiple bone surgery indications.”
Choice Spine’s portfolio includes both hardware and orthobiologics. It offers niche spinal implant solutions with a focus on minimally invasive spine (MIS) solutions. According to the press release, its MIS solutions include “the Thunderbolt™ Minimally Invasive Pedicle Screw System and the Triton™ 3D printed SI Joint Fixation System.” Additional solutions include its bone graft solutions as well as its “BioBond™ 3D printed interbodies, a shallow docking access system for direct lateral surgery, and multiple cervical fusion options.”
OTW also spoke with Chabanas about goals for the partnership for the remainder of this year and he said, “We are currently in the early stages of the collaboration, focused on the technical side of integrating our technologies and investigating the market potential of the solution.”

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.
