摘　　要：目的　探讨骨肿瘤切除后大块骨缺损的修复重建方法。　方法　 1998年 5月～ 2 0 0 2年 5月 ,根据肢体骨肿瘤切除后造成骨缺损的部位及大小形状 ,选择深低温冷冻同种异体骨制备成与之大体匹配的骨半关节、骨干段或骨条、骨粒修复骨缺损 ,辅以交锁髓内钉或加压钢板螺钉行坚强内固定。　结果　本组 2 2例 ,术后随访 3～ 4 2个月 ,无瘤存活 2 0例 ,死亡 2例。其中 1例行半膝关节移植者出现排异反应 ,伤口不愈合 ,经皮瓣修复仍不愈合而截肢 ;其余 2 1例患者摄 X线片和 /或 99m Tc SPECT检查提示均有不等量骨痂生成和 /或核素浓集 ,提示有骨愈合。患肢术后功能恢复以Markin骨移植结果评定标准评定 ,优良率达 81.8%。　结论　应用同种异体骨、关节移植修复骨肿瘤切除后骨缺损是一种理想有效的修复方法 ,值得进一步研究和推广应用。Objective To study the reparative and reconstructive methods for the large bone defect due to the excision of bone tumor. Methods According to the size and shape of the bone defect, we selected the proper bone and joint or manipulated bone segment of the profound hypothermia freezing allograft and gave locked intramedullary nails or steel plate and screws for stable internal fixation. Results In the 22 cases, 20 survived without tumor and 2 died. One patient treated with the allograft of semi knee joint was found rejection. Then the wound did not heal. After the skin flap grafting was performed, the wound still did not heal, so the patient accepted amputation(4.5%). In the other 21 cases, the X ray and 99m Tc SPECT showed some callus or concentration of nuclein which implied bone union. According to Markin bone graft criterion, the excellent rate of function recovery was 81.8%. Conclusion Allografting of bone and joint is a good and workable method in repairing and reconstructing the bone defect due to the excision of bone tumor. It should be further studied and be applied.
