Graft constraint device

A device for constraining graft material packed into a bone defect or a space for buttressing an adjacent bone fragment, said device comprising a graft restraining member having one end with means for constraining the graft material and an opposite end for receiving fastening means for securing the graft restraining member to a stable bone cortex, said graft material comprising a hardenable synthetic material, said means for constraining the graft material being applied as a buttress for containing the synthetic graft material after said synthetic graft material hardens, said means for constraining said synthetic graft material including projecting members inserted into said synthetic graft material before said synthetic graft material hardens so that after said synthetic graft material hardens, said projecting members become integral with said synthetic graft material to hold the hardened graft material in position and prevent translation movement thereof.
