Partially degradable acrylic bone filling material and preparation method thereof

The invention provides a partially degradable acrylic bone filling material and a preparation method thereof and relates to the biomaterial technology in the field of bioengineering. An acrylic bone filler composition includes a polymethyl methacrylate powder, a contrast agent solid powder, a methyl methacrylate monomer, and MDO. Compared with the prior art, the preparation method has the advantages that the degradation performance of the acrylic bone filling material is optimized, so that the acrylic bone filling material can be gradually degraded in the cone to reduce the volume and is partially replaced by new bones while the original mechanical property is not changed, and the current situation that sclerotin around a filling area is dissolved and necrotic due to the fact that an existing bone filling material is left in a body for a long time is improved. 本发明提供了一种可部分降解的丙烯酸类骨填充材料及其制备。本发明涉及生物工程领域中的生物材料技术。一种丙烯酸类骨填充材料组合物，包含聚甲基丙烯酸甲酯粉末，造影剂固体粉末，甲基丙烯酸甲酯单体和MDO。与现有技术相比，本发明的优点是：优化丙烯酸类骨填充材料的降解性能，使其在不改变原有力学性能的同时，能够在锥
