Abstract

The present invention relates to techniques for the preparation and implantation of implants with surgical cements composed primarily of calcium sulfate ("CS"). The first of these novel techniques involves the steps of: (1.) precoating an implant with CS; (2.) permitting the implant to dry, and, (3.) thereafter grouting the implant in place with wet CS. The second embodiment involves: (1.) grouting an uncoated implant in place with wet CS. Finally, the third embodiment involves: (1.) precoating an implant with CS; (2.) permitting it to dry; and, (2.) subsequently press-fitting the implant in place without grouting.
