Demineralized Bone Matrix (DBM)

The natural process of demineralization and then remineralization that happens in our bodies is known as bone remodeling. About 10% of the human skeleton is undergoing remodeling at any given time. The demineralization of donor bone utilizes what we know about natural demineralization, but instead of partial demineralization, the entire bone is demineralized enhancing its ability to facilitate bony fusion.

Demineralized bone matrices (DBM) provide a scaffold and signaling proteins that encourage cells to become osteoblasts. Osteoblasts are bone cells that create the mineral matrix that hardens bone.1,2

DBMs come in a wide variety of forms including chips, particulates, fibers, and cubes. DBMs have enhanced signaling compared to mineralized bone grafts and are used when more biological help is needed to encourage fusion.

  • Osteoconductive: Natural bone matrix facilitates cell attachment and proliferation, and vascular in-growth
  • Osteoinductive: Provide natural levels of proteins that encourage mesenchymal stem cells to become osteoblasts
  • Available in cortical only, cancellous only, or corticocancellous
  • Different shapes and sizes are available to meet multiple surgical needs

*Autograft is partially demineralized, and therefore its osteoinductivity (signals) are unenhanced compared to grafts with fully demineralized bone.

  • DBMs can be used
    • to fill any bony defect
    • as an extender for autograft
    • to enhance handling of challenging types of autograft, such as reamer/irrigator/aspirator (RIA)
  • DBMs can provide enhanced signaling properties for patients who are at risk of a nonunion
