Objective　To manufacture adriamycin-porous tricalcium phosphate (A-PTCP) ceramic drug delivery system (DDS)as a possible method for bone defect treatment after bone tumor operation. Methods　A-PTCP DDS was made from putting adriamycin into PTCP. Thirty rabbits were divided randomly into group A(24 rabbits) and group B(6 rabbits). A-PTCP was implanted in the greater trochanter of the right femur in group A. Adriamycin were injected into veins in group B. Muscle around A-PTCP and plasma were taken out at different period. Adriamycin concentrations in muscle and plasma were measured by high performance liquid chromatography (HPLC). Results　A-PTCP could gradually release adriamycin over 10 weeks. Adriamycin concentrations in the muscle were higher than that in plasma. Conclusion　A-PTCP may be a new method for repairing bone defects after bone tumor operation.
