BONE FIBER TECHNOLOGY Bone Grafting (Spine and Orthopaedic)


Most demineralised bone products on the market are made with particles, created by grinding the bone into a powder and then demineralising it.

Bone fibers are created by a proprietary milling technique, and they produce a greater osteoconductive structure.1

Medtronic was first to market with a fiber-based DBM. Our aseptically processed fibers have some of the highest osteoinductive scores* on the market and this interconnected mesh of fibers enhances the osteoconductive potential of the product by providing a path for cellular infiltration. Grafton™ DBM and Magnifuse™ Bone Graft are fiber-based DBMs.*

Fiber-based DBM is a more effective osteoconductive structure than particle-based DBM.1 With fiber-based DBM, bone cells are able to attach and proliferate through the network of demineralised bone fibers.
