There have been obtained high-filling polyurethane compositions with hydroxyapatite. Compositions with hydroxyapatite and immunomodulator in the polyurethane base acquire better adhesiveness and improved strength characteristics as evidenced by physical-and-clinical studies made. Modal operations are developed in test animals on bone defects replacing that carry a high mechanical load. Histological studies showed that polyuretane-base high-filling polymeric compositions replace the loss of bone fully, stimulate the processes of bone formation, with no negative responses of the osseous tissue noted.
