Regulatory officials in Europe have granted the CE mark to Ranier Technology Limited’s fusion cage made of its proprietary polymeric material. Called the Anatom-C, the material has a stiffness specifically selected to match the stiffness of cancellous bone, according to Ranier’s press release. Company officials note that standard fusion cages have been made from materials such as titanium and PEEK which are significantly harder than bone.

Unlike fusion cages made from titanium or PEEK, Ranier officials say the Anatom-C cage is coated with calcium phosphate as well as being anatomically shaped to match the natural cervical anatomy. The Anatom-C comes in 15 different sizes with the smallest being 4mm in height.
Scott Johnson, M.D., the head of development said “Using our unique polymer science coupled with in-line, injection molding technology, we have created a product that meets surgeon’s needs and can be manufactured at significantly lower costs than current products.”

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.
