Bone cement composistion containing microencapsulated radiopacifier and method of making same |
摘要 |
A radiopaque bone cement used to repair bone or other hard tissues is provided. The bone cement is made from combining a composition containing an acrylic powder and a radiopacifier with a corresponding liquid monomer. Prior to being added to the composition, the radiopacifier is microencapsulated with a bone cement compatible material. When combined with the liquid monomer, the bone cement compatible material dissolves releasing the radiopacifier particles into a bone cement matrix. By being microencapsulated, the radiopacifier is prevented from agglomerating in the cement. Instead, the radiopacifier particles become dispersed throughout the bone cement matrix which not only creates a radiopaque cement but also increases the fatigue life of the cement.
