AAA骨与自体红骨髓复合移植治疗骨缺损

目的 :探讨同种异体低抗原脱钙骨 (AAA骨 )与自体红骨髓复合移植对良性肿瘤刮除后骨缺损修复能力的影响。方法 :58例 66处长骨良性肿瘤刮除后 ,其骨缺损残腔用AAA骨与自体红骨髓复合物充填 ,术后随诊 42例 49处骨缺损 ,每 2个月复查X线照片 1次 ,随访时间 1～ 3年。结果 :49处骨缺损均在 9个月内骨性愈合 ,平均时间为 6个月 ,优良率达 93%。结论 :AAA骨与红骨髓复合物修复骨缺损 ,其疗效显著 ,可视为骨缺损修复的理想材料

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.
