Move the needle in fusion with speed and efficiency
MagnetOs Putty
Molding our solutions to your needs. MagnetOsTM Putty is our most robust moldable formulation. Delivering resilient handling with all the benefits of our NeedleGripTM powered surface technology.1,3
Simply warm MagnetOs Putty in your hands, mold into the desired shape, and use it to fill voids and spaces found in joint fusion or traumatic indications of the foot and ankle and upper extremity.1,3
Powered by harnessing the immune system
MagnetOs Putty is capable of polarizing macrophages from the M1 pro-inflammatory to the M2 pro-healing phenotype, which is known to influence bone growth through the secretion of proteins such as BMP-2. Furthermore, MagnetOs has demonstrated the ability to form bone in a canine intramuscular pouch model without the addition of cells or growth factors.*†‡2,4,5 These understandings and evidence combine to define MagnetOs as a powered solution for predictable fusions and traumatic reconstructions of the extremity.
Easy to store with predictable handling
Unlike frozen allografts, MagnetOs can be stored at ambient temperature (max. 45ºC / 113°F) with no special requirements.3 MagnetOs Putty is ready-to-use straight out of the package with no preparation time or thawing needed. The carrier is designed to maximize handling properties, so you can twist, tear, and mold it into any shape desired before implantation and remain confident that it will stay in place during fusion related joint compression while also resisting migration and irrigation.1,3,6,7
Free of animal & human tissues
MagnetOs Putty contains no animal or human-derived tissue – just like MagnetOs Granules and MagnetOs Easypack Putty.1,3 This alleviates patient concerns during consent for use of allograft or xenograft-derived products in surgery.
