Massachusetts-based Ranfac Corporation is now giving doctors the ability to percutaneously harvest a bone dowel using the systems introducer cannula.
Ranfac Corporation Takes Bone Marrow Harvesting to Next Level

As stated in the August 19, 2015 news release, “The Marrow Cellution System allows the user to harvest bone marrow in small amounts in a measured and controlled manner over a large geography inside the marrow space. Independent research has demonstrated that smaller aspirations over a greater sampling area increases cell yield by reducing peripheral blood contamination.”
Harlan Adler, VP of Sales and Marketing at Ranfac, told OTW, “During the development process we learned that there was a large demand to percutaneously harvest bone dowel and combine that with our high quality bone marrow aspirate to be used in a variety of procedures. By using a larger gauge needle with a swaged distal tip and developing a special extraction cannula, we are able to allow users to combine our proprietary bone marrow aspiration method with the ability to percutaneously harvest a bone dowel through a single device.”
“In one year we hope to have distribution established across of the U.S. and Europe and to see the device be incorporated into some of the larger practices in the country.”

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.
