CALCIUM PHOSPHATE CEMENT COMPOSITE FOR BONE DEFECT FILLING Russian patent published in 2013 - IPC A61L24/02 A61L27/02 A61L27/12 A61F2/28

Abstract RU 2484850 C1

FIELD: medicine.

SUBSTANCE: invention refers to medicine and concerns composites for plastic reconstruction of the injured bone tissues. The composite is presented in the form of reaction-set mixed powders: tricalcium phosphate, containing hydroxyapatite particles ranging in size from 38 to 220 mcm. Fluid cement is presented by a solution of magnesium, potassium and/or sodium phosphates, phosphoric acid and water. The components are taken in certain proportions. In the process of the material setting, a solid frame with a uniform distribution of ceramic particles contributing to an increase in strength is formed.

EFFECT: high mechanical properties and availability of raw materials allows using the given material widely for closing the bone cavities.
