Abstract: A bone material composite granule, a manufacturing method and usage method thereof, and a bone cement constructed using the composite granule. The bone material composite granule comprises a co-polymer of a hydroxyethyl methacrylate (HEMA) and methyl methacrylate (MMA) and a calcium phosphate coated on the surface of the co-polymer. A synthesized bone replacement material has improved biocompatibility, bone conduction, and rheological characteristics, and enhanced mechanics and mechanical performance. The bone material can be used in the fields of osteonecrosis, osteoporosis, osteoarthritis, vertebroplasty, bone fracture, bone cyst, alveolar atrophy, subchondral bone defect, subchondral bone cyst, maxillofacial surgery, plastic surgery, minimally invasive procedure, and the like.
