Allograft cortical bone grafts were used for internal fixation to repair bone defects in the metaphyseal and diaphyseal bone. Twenty-one patients underwent massive allogeneic bone grafting after removal of the tumor segment. The implanted bone did not include the articular surface. Among them, 12 cases were primary malignant bone tumors, 3 cases were solitary metastatic bone tumors, and 6 cases were benign lesions. The malignant patients were graded according to Enneking surgical stage, 3 cases of I_A stage, 5 cases of I_B stage, 3 cases of II_B stage and 4 cases of stage III patients. The average follow-up time of 20 survivors was 4.4 (1–13) years, and 1 patient died of metastatic disease 2 years after surgery. Preoperative examination package
