Decortication Dental decortication refers to the intraoperative perforation or removal of cortical bone to induce bleeding and the release of bone forming cells from the underlying marrow. It is routinely used in combination with onlay block grafts or guided bone regeneration (GBR) procedures.What is the biologic rationale for bone decortication?
Background: Bone decortication is often performed as part of a guided bone regeneration (GBR) procedure. The biologic rationale for decortication of bone is to allow progenitor cells easy access to a GBR-treated site and to facilitate prompt angiogenesis. It also may enhance the physical connection between a bone graft and a recipient site.What is decortication and how does it work?
Decortication has been shown to promote the fusion process and provides not only a rich source of vascular supply from the underlying cancellous bone, but also access to pluripotent stem cells within the marrow.Why decortication for spinal fusion?
Decortication has been shown to promote the fusion process and provides not only a rich source of vascular supply … Despite the development of innovative approaches and the general success that has been achieved with spinal fusion, the rate of nonunion in some studies has been reported as high as 35%.
