Durham, North Carolina-based Bioventus, Inc. has announced the launch of OSTEOAMP SELECT Flowable, an allograft bone graft substitute solution for a range of procedures including lumbar spine fusion, cervical spine fusion and foot and ankle fusion, but most interestingly, was designed specifically to work with 3D-printed cages.

OSTEOAMP SELECT Flowable, which comes in three sizes from 2.5 to 10 cc, is 100% allograft—no synthetic carrier added.
“Spine, trauma and foot & ankle surgeons are looking for allograft options that handle well for a variety of procedures,” said Dr. Larry Boyd, company vice president, Product Development. “Developed by our team in collaboration with our tissue bank partner, OSTEOAMP SELECT Flowable comes ready-to-use, and is designed to be delivered in a range of methods, and to provide excellent retention characteristics at the grafting site. It is terminally sterilized and processed using advanced procedures designed to comply with the highest standards for tissue banking, including comprehensive donor screening and extensive microbiological testing.”
“A differentiated allograft product with the handling characteristics like OSTEOAMP SELECT Flowable is an asset for a spine surgeon who uses 3D printed cages where grafting can be challenging,” said Dr. Safdar Khan, Ohio State University. “I was impressed to see how the flowable product filled a cage with a tight, porous structure so well and stayed in place during implantation.”
In addition, Dr. Boyd noted, “OSTEOAMP bone allograft is a uniquely processed bone and retains the bone marrow during the processing in order to retain a wide array of naturally occurring growth factors to help with each phase of the bone healing cascade.”
Explaining to OTW how OSTEOAMP helps in cases with 3D printed cages, Dr. Boyd stated, “The advancement of 3D-printed and expandable cage technology has been exciting to watch. However, the traditional bone graft formats can make it challenging or even impossible to graft some of these new cage designs. As the name implies, OSTEOAMP SELECT Flowable will flow through the small channels of a 3D-printed cage and will flow through narrow tips and cannulas to backfill expandable cages.”

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.
