Biomaterial Implants To facilitate fusion, bone graft is often applied in the lateral gutters. A suitable bone graft substitute (e.g. chronOS, DBX) may be used by itself or in combination with autograft. The construct shown is complemented with chronOS Strip precast, which optimally integrates with patient anatomy and implanted hardware.
