[Graft of AAA bone combined with autologous red bone marrow for treatment of bone defects]

To evaluate the effect of autolyzed antigen-extracted allogenic bone ("AAA" bone) graft combined with autogenic red bone marrow on bone defects, 58 cases with benign bone tumor(66 long bones) were treated with curettage operation, and the post-curettage bone defects were filled with the complex of "AAA" bone combined with autogenic red bone marrow. Forty two cases(49 bones) were followed up by taking X-ray radiography every 2 months in a period of 1-3 years. The result showed that 49 bones all got bony healing within 9 months(6 months in average). It is suggested that "AAA" bone combined with autogenic red bone marrow may be an ideal material for bone defect repairing.
