23 Jul Bone restoration support frame for bone tuberculosis treatment and preparation method thereof
Abstract
The invention relates to a bone restoration support frame for bone tuberculosis treatment and a preparation method thereof, and belongs to the technical field of biomedicine engineering. The bone restoration support frame contains strontium-doped nanometer hydroxyapatite, gelatin and sodium alginate medicine carrying microspheres. The bone restoration support frame has an antituberculous medicineslow release system of a three-dimensional porous support frame structure. Compared with implementing bodies with other forms, the support frame has the advantages that the cell and blood vessel growth is facilitated; the new bone regeneration is promoted; the antituberculous medicine is effectively released for a long time in the local part of the tuberculosis disease; the good local environmentis provided for bone defect healing. The medicine carrying anti-bone tuberculosis restoration support frame has good mechanical property and biocompatibility; the antituberculous medicine can be continuously released; good bone induction capability and bone conduction capability are realized; the regeneration of the bone tissue defect position can be induced.
