About MagnetOs
Growing bone with MagnetOs^TM gives surgeons confidence where it matters most – delivering predictable fusion outcomes.¹In a Level I human clinical study published in Spine, MagnetOs achieved nearly twice the fusion rate of autograft (79% vs. 47%) in posterolateral fusions (PLFs).¹Among active smokers – who made up 1 in 5 patients – the fusion difference between MagnetOs and autograft was even more dramatic.^*1,2MagnetOs grows bone on its own thanks to NeedleGrip^TM – a proprietary submicron surface technology that harnesses the immune system to stimulate bone growth, without added cells or growth factors.^†3-5Ready-to-use, easy to mold, and reliably staying put, MagnetOs carries no intrinsic risk of human tissue-related disease transmission and is FDA cleared for use throughout the spine, including interbody procedures.^‡6-11 Additionally, MagnetOs Granules, MagnetOs Putty, MagnetOs Easypack Putty and MagnetOs MIS are also cleared for use in the extremities and pelvis.^7-10
