A bioabsorbable device made of synthetic material intended to be implanted into the body to provide osteoconductive bone-tissue scaffolds, and sometimes osteovascularization, to replace bone lost through trauma, surgery, or pathological conditions (e.g., osteoporosis); it does not include an antimicrobial agent(s). It may be made of ceramics (e.g., tricalcium phosphate or hydroxyapatite), bioactive glasses/minerals/metals (e.g., strontium), or bioabsorbable polymers. It is used to fill cystic defects, repair fractures, and/or extend autogenous bone grafts and is typically provided as cancellous blocks, chips, or granules of varying sizes, or mouldable/fluid materials.
