Abstract
The present invention relates in general to implantable flexible bone composites, and method for preparing the same. The flexible bone composite includes at least one polymeric layer and at least one calcium-containing layer. The polymeric layer can be a polymeric layer including a synthetic polymer. The calcium-containing layer can include a calcium compound such as β-Ca3(PO4)2. The flexible bone composites of the invention are useful as bone void fillers and have improved handling characteristics.
