Biocompatible bone implant compositions and methods for repairing a bone defect

Abstract From the Canadian patent

Moldable bone implants for use in a bone defect or wound include a plurality of biocompatible granules and a biocompatible polymer that together form an implant mass. The polymer is softened with a plasticizer to make the implant mass moldable or flowable. The plasticizer can dissipate or be extracted to cause the implant mass to harden. The implant mass can be shaped in-situ or exsitu. Implants formed in-situ are shaped by the bone defect or wound. The implant becomes hard through contact with body fluids which extracts the , plasticizer from the implant mass. Bone implants formed ex-situ such as in a , mold, are shaped by a mold for example, and then hardened by placing the implant …
