Abstract: Grafting materials are disclosed that are fabricated from citrate-based materials. The grafting materials have particular applicability in forming a biodegradable scaffold and generally include a composition that includes (i) a citrate component, (ii) a polyol, and (iii) particulate inorganic material. The polyol may take the form of a diol, e.g., butanediol, hexanediol, octanediol, or polyethylene glycol. The scaffold may take the form of a crosslinked polymer network, may be biodegradable, and may be 50-90% porous. The scaffold may be conformable and may be adapted to be cut in an operating room.
