US 6,224,635 B1 · Implantation of surgical implants with calcium sulfate

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.

Dependent claims

A method of implanting a surgical implant within the body of a patient, the method comprising the steps of:

(a) at a pre-operative site, preparing a wet surgical cement comprised primarily of a calcium sulfate having a solubility in pure water at 25 degrees C. in a range of about 0.5×10−2 M to about 20×10−2 M in which said wet surgical cement further comprises an accelerator/stabilizer component selected from the group consisting of alkali metal fluorides, alkaline earth fluorides, and combinations thereof;
(b) at a pre-operative site, coating said surgical implant with said wet surgical cement;
(c) at a pre-operative site, causing said surgical cement to dry upon said implant;
and
(d) at an operative site, grouting said implant and placing said implant into place within the body of said patient using a grouting material composed primarily of said wet surgical cement.
