The Integra OS Osteoconductive Scaffold - Putty is a resorbable bone void filler made from a porous highly purified collagen matrix that has high purity tricalcium phosphate (TCP) granules dispersed throughout. The implant is provided sterile, nonpyrogenic, for single use in double peel packages. The Integra OS Putty bone grafting construct is designed to facilitate the repair of bony defects. In the dry state, the matrix has a three dimensional trabecular network of pores that resembles the pore structure of human cancellous bone. The Integra OS Putty quickly imbibes fluids, making it easy to combine with bone marrow aspirate. Integra OS Putty guides the regeneration of bone across the defect site into which the Putty is implanted. New bone forms in apposition to the matrix surface when the graft is placed in direct contact with viable host bone. Ultimately the matrix is resorbed and remodeled into bone.
A sterile bioabsorbable device made of synthetic bone substitute materials (e.g., ceramics such as tricalcium phosphate or hydroxyapatite) combined with bone growth factors (e.g., bovine collagen) implanted into the body to provide osteoconductive bone-tissue scaffolds to replace bone lost through trauma, surgery, or pathological conditions (e.g., osteoporosis). It is used to fill cystic defects, repair fractures, and/or extend autogenous bone grafts. It is typically provided as cancellous blocks, chips, or granules of varying sizes, or mouldable materials.
