MagnetOs for predictable fusions
A bone graft like no other
MagnetOs is a bone graft like no other: thanks to its NeedleGrip™ surface technology, it grows bone even in soft tissues.* This surface technology provides traction for our body’s vitally important ‘pro-healing’ immune cells (M2 macrophages).†‡1,2
This in turn, unlocks previously untapped potential to stimulate stem cells – and form new bone throughout the graft.†§3-6
The growing body of science behind NeedleGrip is called osteoimmunology. But for surgeons and their patients it means one thing: a more predictable fusion.†¶5,6

MagnetOs Mechanism of Action
1. Polarize
Circulating immune cells (monocytes) differentiate into macrophages that are subsequently polarized, by the submicron needle-shaped features of MagnetOs’ Needlegrip surface.
As a result, they become the pro-healing, anti-inflammatory M2 macrophage phenotype.†2,6
2. Regenerate
In natural bone homeostasis, it is well established that M2 macrophages play a critical role.
M2 macrophages communicate with local stem – and progenitor cells via secretion of regenerative signaling factors, including osteoactivin and BMP-2.6,12,13
These signaling factors induce mesenchymal stem cells to migrate, proliferate, and differentiate into osteoblasts that lay down osteoid.6,13-15
Endothelial cells are stimulated to form capillaries that deliver nutrients and yet more osteogenic cells to the site of repair.6,13
3. Propagate
Non-unions tend to happen in the core of large-span defects, as seen in spinal fusions.
NeedleGrip propagates bone in this core region – by interacting directly and indirectly with circulating osteogenic cells – rather than only from the outside-in via creeping edge repair.†‡2-5
What surgeons are saying about MagnetOs
MagnetOs:
the evidence
MagnetOs is proven to be equivalent to the gold standard of autograft for fusions in the spine, in a Level-1 study.16 Furthermore, it is supported by an unprecedented blend of peer-reviewed scientific, pre-clinical and clinical studies through Project Fusion: our global research program, where science and clinical evidence meet.
