RESORBABLE RADIOOPAQUE CROSS-CALCIUM-PHOSPHATE CEMENT FOR BONE PLASTICS

摘要

FIELD: medicine.;SUBSTANCE: invention relates to medicine, namely the production of radiogenic contrast cements for closing small cavities in bone tissues. Radiopaque injectable calcium phosphate cement for bone plastication contains as an X-ray contrast material tantalum oxide Ta₂O₅, additionally contains monocalcium phosphate monohydrate (MCPM), and as a quenching liquid – a mixture of colloidal silicate suspension (CCS) with polyethylene glycol (PEG) with the following ratio of components, mass %: dry mixture: TCP – 55.1–62.9 %; MCPM – 29.9–34.1 %; Ta₂O₅ – 3–15 %; gauging liquid: KSS – 90 %, 95 %; PEG – 5 %, 10 %.;EFFECT: technical result of the invention consists in simplifying the composition of the radiopaque injected calcium-phosphate cement by providing the optimal flow and radiopacity parameters without the introduction of special improvement additives while increasing the safety of use.;1 cl, 1 tbl
