四肢骨肿瘤切除后大块骨缺损的显微外科治疗

Microsurgica Treatment Of Massi ve BoneDefect after Bone Tumor Resection

自１９８０年２月～１９８９年３月应用显微外科技术治疗四肢骨肿瘤切除后大块骨缺损共３９例。其中良性骨肿瘤２０例，恶性１９例。吻合血管的腓骨移植２２例，髂骨移植６例；带血管蒂的腓骨移植４例，髂骨移植７例。术后随访时间２～９年。结果成功３７例，恶性骨肿瘤术后局部复发行截肢１例，肺转移死亡１例，成功率为９４．８％。骨愈合时间较传统的骨移植缩短，平均为２．８个月。恶性骨肿瘤术后两年以上无瘤存活率达８９．４％。

AbstractFrom February 1980 to March 1989,a total of 39cases of massive bone defects preduced followin8 bone tu-mor resections were repeired by microsurgical technique. There were 20 ben1gn and 19 mailgnant bone tumors. The surgical procedures consisted of anastomotic and vasculartdisedicle bone grafts,j.e,fibula grafts in 26 cases andiliac bone grafts in 1 3 cases.Chemotherapy was done forthe cases with the malign ant bone tumors.All were fol-lowed up from 2～9years with an average of 4.5 years. The successful results were seen in 37 cases(94.8%). The two years survival rate of the cases with malignanttumors was 89.4%. The grafted bone healed up from 2.5to3.5 months after the operation.
