The purpose of this multi-center, prospective, observational registry is to gather information on the clinical outcomes and real-world use of commercially available bone graft substitutes manufactured by OssDsign® AB, in patients who require spine fusion.

This multi-center study (up to 25 US study sites) is a post market, prospective, observational spine fusion registry.
