POROUS CALCIUM PHOSPHATE CEMENT

摘要

A kit and a method for making a porous cement which self sets to hydroxyapatite and has an interconnected porosity is produced by mixing a calcium source and a phosphate source with a carbonate source and mixing thi s powdered component with a liquid component having an acid component. The liquid component comprises water on an aqueous solution containing an acid. The acid and the carbonate react to form carbon dioxide thereby producing an interconnected porosity in the normally solid self-hardening bone cement. Th e method requires only a relatively low weight percent of the acid and base to be mixed with the liquid and powder cement components.
