AlloSync™ Expand Demineralized Cortical Fibers for Spinal Fusion Cases

The unique long-strand geometry of AlloSync™ Expand 100% demineralized cortical fibers maximizes graft cohesion1 and provides a 3D interconnected matrix to promote cell migration across the bone void. AlloSync Expand fibers have demonstrated superior bone-forming capacity compared to standard particulate demineralized bone marrow.2 After hydration, the graft will expand to fill the void and create endplate-to-endplate contact in spinal fusion cases. AlloSync Expand fibers can be hydrated with biologic fluids, such as platelet-rich plasma or concentrated bone marrow aspirate.
