any of the above described plug embodiments the plug can be used alone associated with standard rehydrating solutions such as previously described associated with autograft tissue such as iliac crest local bone and or marrow blood plasma or serum obtained at the time of implantation or sometime prior to implantation as well as combinations thereof in certain embodiments the plug will be placed at an implant site in the as packaged condition in alternative embodiments the plug can be rehydrated just prior to implantation as previously stated the plug form of the osteoimplant herein can be inserted into the cavity of the implant as is or if desired it can be suitably compressed prior to insertion into the implant or defect site when the plug is compressed just prior to its insertion any excess liquid or moisture will be displaced from the material as the volume of the plug is temporarily reduced in this embodiment the compressed plug being smaller than its receiving cavity is easily inserted into such cavity after relaxation of the applied compressive force the plug will substantially return to its original volume thus assuring its retention in the cavity the foregoing description and embodiments were chosen and described to best explain the principles of the invention and its practical applications thereby enabling others skilled in the act to best utilize the invention in its.
