ABSTRACT:
A new surgical cement is disclosed. This surgical cement comprises a hardened cement formed from a mixture comprising a cementing component selected from the group consisting of calcium components having a solubility in water at 25.degree. C. in the range of about 0.5 .times. 10.sup.-2 M to about 20 .times. 10.sup.-2 M and mixtures thereof; a setting component selected from the group consisting of water soluble salts of polyfunctional carboxylic acids containing 2 to about 10 carbon atoms, water soluble dibasic phosphate salts and mixtures thereof; and water in an amount effective to form a paste from the mixture which paste hardens into said hardened cement which is biocompatible.
